Sources & evidence

The records behind this guide, with the dates and limits of each source.

1. 1

   Supplied workload observation 1

   ObservationRecorded 2026-10-09
   Buyer-supplied constraint: Mac mini M6/Mac18,5, 32 GB, macOS 27; measured rear host 40 Gb/s TB4/USB4; Gen2x2 falls to 10 Gb/s
   Buyer-supplied measurements or requirements dated in the ledger; retained on file. They are a use-case example, not independently collected laboratory measurements.
2. 2

   Supplied workload observation 2

   ObservationRecorded 2026-10-09
   Buyer-supplied measurements: 66 GiB workspace + ~22 GiB logs; 88 GiB combined starting case
   Buyer-supplied measurements or requirements dated in the ledger; retained on file. They are a use-case example, not independently collected laboratory measurements.
3. 3

   Supplied workload observation 3

   ObservationRecorded 2026-10-06
   Buyer-supplied measurement: up to 16 GiB writes observed 2026-10-06; quiet days near zero; not established net growth or average
   Buyer-supplied measurements or requirements dated in the ledger; retained on file. They are a use-case example, not independently collected laboratory measurements.
4. 4

   Supplied workload observation 4

   ObservationRecorded 2026-10-09
   Buyer-supplied workload: ~116k files; 0.2–0.3 GiB models/CSVs plus many small files; long writes/heavy reads
   Buyer-supplied measurements or requirements dated in the ledger; retained on file. They are a use-case example, not independently collected laboratory measurements.
5. 5

   Supplied workload observation 5

   ObservationRecorded 2026-10-09
   Buyer requirement: APFS one-volume workspace because cp -c clones must stay on same volume
   Buyer-supplied measurements or requirements dated in the ledger; retained on file. They are a use-case example, not independently collected laboratory measurements.

   Mac link ceiling

   OfficialRecorded 2026-10-10
   Apple specifies rear Thunderbolt 4/USB4 ports up to 40 Gb/s and front USB ports up to 10 Gb/s on Mac mini M6. The supplied host uses the rear 40 Gb/s path. Its USB 3.2 Gen 2x2 drives fall back to 10 Gb/s; 80 Gb/s devices gain no extra link bandwidth on this host.
   A link ceiling is not a measured file-transfer rate.

   APFS and one-volume requirement

   OfficialRecorded 2026-10-10
   Disk Utility supports APFS and encrypted APFS on external disks. The demanding workspace requires one APFS volume because its cp -c clone workflow does not cross volumes; splitting models, logs or caches that need shared clones would defeat this requirement.

   Unattended mount and encryption

   JudgementRecorded 2026-10-10
   Apple describes password entry when an encrypted external device is connected. Unattended unlock after reboot cannot be assumed. Editorial bring-up requirements: connect directly using the included/rated cable; verify mount and unlock after reboot and repeated sleep/wake; gate analysis startup on the intended volume identity; verify cloning and a restore from an independent backup. A working volume is not its own backup.
   This is an operational recommendation, not a certification that a shortlisted device passes these checks or a change to the user's machine.

   Capacity units and reserve

   CalculationRecorded 2026-10-10
   Manufacturer decimal TB uses 10^12 bytes; GiB uses 2^30 bytes. Thus 2 TB = 1862.645149 GiB and 4 TB = 3725.290298 GiB. The planning model reserves 20% of total capacity, an editorial headroom assumption, not an APFS or warranty requirement. Horizon = (0.8 × capacity_GiB − starting_GiB) / daily_net_growth_GiB.
   Reproduced with decimal arithmetic. Nominal units and an explicit reserve are used; formatting overhead, snapshots, metadata and physical allocation can change usable space.

    Capacity horizons with logs and reserve

    CalculationRecorded 2026-10-10
    For an 88 GiB start with 20% reserve: 2 TB has 1402.116119 GiB growth headroom; 4 TB has 2892.232239 GiB. At 5/10/16 GiB per day of net growth, horizons are 280.423/140.212/87.632 days and 578.446/289.223/180.765 days respectively; nearest-day presentation is 280/140/88 and 578/289/181.
    Assumes constant retained net growth, not gross write traffic. The measured peak write day does not establish that forecast.

    Sensitivity to logs and reserve

    CalculationRecorded 2026-10-10
    With 66 GiB start and 20% reserve, 2 TB lasts 284.823/142.412/89.007 days and 4 TB 582.846/291.423/182.140 days at 5/10/16 GiB/day. With 88 GiB start and no reserve, horizons are 354.929/177.465/110.915 and 727.458/363.729/227.331 days. These are mathematical ceilings with stated assumptions.

    Capacity decision thresholds

    CalculationRecorded 2026-10-10
    With 88 GiB start and 20% reserve, maximum average retained net growth for 1/3/5 years is 3.839/1.280/0.768 GiB/day on 2 TB, and 7.919/2.640/1.584 GiB/day on 4 TB. Years use 365.25 days. At sustained net growth of 16 GiB/day, neither capacity is a multi-year solution.
    Rounded thresholds are planning figures, not exact safe limits; choose capacity against actual retention and growth.

    Host writes versus TBW

    CalculationRecorded 2026-10-10
    A constant 16 GiB of host writes every day is 5844 GiB or 6.274947 decimal TB/year; over 5 years it is 31.374736 TB. This is 2.614561% of 1200 TBW and 1.307281% of 2400 TBW. It is a scenario, not the measured average, NAND write-amplification prediction or a warranty extension.
    Warranty time and exclusions still apply even if the rated host-write amount is not reached.

    Corsair post-cache test and capacity limit

    ResearchRecorded 2026-10-10
    Tom's tested the 2 TB EX400U on Windows USB4. Its later same-method comparison with E82 reports about 1.8 GB/s initial writes, then roughly 1.55–1.65 GB/s after about 20 seconds, held for 30 minutes. The earlier review likewise found strong long-run writes and a hot metal top. No controlled 4 TB M6/macOS 27 APFS result or low-QD numerical dataset was established here.
    These are laboratory results for the reviewers' samples, not our measurements. The guide does not promise the 4 TB Mac result will equal the 2 TB Windows result.

    TechRadar's author used an M4 Mac mini, a no-heatsink Samsung 990 Pro 4 TB and Express 1M2, formatted APFS; Blackmagic read/write results were around 3100 MB/s. This is a useful near-target pairing observation, not a post-cache, encrypted APFS or repeated sleep/wake test on M6/macOS 27.

    Macworld tested an 8 TB OWC-configured Express 1M2: AJA write/read about 2736/2980 MB/s and Blackmagic over 3 GB/s, with no reported speed collapse during an hour and surface around 40 degrees C. That SSD and capacity differ from both DIY builds; an hour of transfer does not establish unattended mount reliability.

    990 Pro 4 TB NAND, endurance and internal sustained test

    ResearchRecorded 2026-10-10
    Samsung's 4 TB 990 Pro specification is TLC V-NAND, 4 GB LPDDR4 DRAM, 2400 TBW and 5 years or the TBW limit, whichever first. Tom's internal PCIe test found post-cache TLC writes above roughly 1.6 GB/s. These figures establish the bare SSD's specification/test, not external throughput. The Malaysia release notice dated 2023-09-08 says availability there from early November 2023; it does not prove the first global sale date.

    SanDisk 2 TB Windows sustained and random IO

    ResearchRecorded 2026-10-10
    Tom's 2 TB E82 test on Windows USB4/Ryzen 7600X/X870E shows about 3.5 GB/s for nearly 3 minutes, 1.1 GB/s for the next 5 minutes, then 0.8 GB/s over the rest of a 15-minute Iometer run. CrystalDiskMark random reads were strong in that comparison but random writes were near its bottom. The plotted random-IO ranking is not a matched QD1 APFS measurement; 4 TB and Mac behaviour remain unmeasured here.

    SanDisk USB4 power requirement

    OfficialRecorded 2026-10-10
    SanDisk support specifies E82 needs at least 15 W (5 V, 3 A) at all times for USB4 performance and 7.5 W for USB 3. It warns that some ports reduce power during idle or sleep. The exact Mac port's uninterrupted delivered power under these conditions was not measured; bus-powered does not imply verified unattended safety.
    This requirement is material to the always-on recommendation and remains visible on the short page.

    TRIM and SMART depend on the path

    ResearchRecorded 2026-10-10
    Howard Oakley's own 2024 test found Express 1M2 with ASM2464PD on Apple silicon USB4 supports both TRIM and SMART. His Intel Mac USB 3 fallback still supported TRIM but not SMART, and System Information could disagree with other tools. Therefore a blanket USB-never-TRIM claim is wrong; exact host, bridge, firmware and negotiation matter. M6/macOS 27 support and HMB passthrough were not independently verified here.
    The article is primary test evidence from its author, not merely a secondary summary. No trimforce recommendation follows from it.

    Always-on stability and controller reports

    ResearchRecorded 2026-10-10
    The checked manufacturer pages, Mac reviews and community reports do not provide a controlled repeated sleep/wake/reboot dataset for these exact M6/macOS 27 options. MacRumors includes ASM2464PD wake/eject reports; an OWC owner reports improvement. These are anecdotes with different revisions/cables/settings, not comparative failure rates for ASMedia versus Intel or proof that a whole chipset family fails.
    No brand is certified for uninterrupted attachment, and absence of a test is not evidence that it fails.

    Samsung warranty limits

    OfficialRecorded 2026-10-10
    Samsung's current SSD warranty covers the stated model/time or TBW limit, subject to exclusions; damage caused by assembly/third-party products is excluded. This is not a blanket declaration that all enclosures void an SSD warranty. The checked Malaysian PDF is an older model schedule, so it cannot certify new 990 Pro limits or the exact retailer's RMA route. Data recovery is not a replacement warranty benefit.

Exact selected RM builds and comparable Mac long-run tests remain unresolved; Satechi/Acasis/UGREEN, OWC Envoy, LaCie and newer E83 variants also remain candidates for a follow-up rather than inferred equivalents.

    Capacity and budget tiers

    JudgementRecorded 2026-10-10
    Editorial tiers compare complete-function reference costs, not fixed budgets: lower-cost 2 TB 10 Gb/s T7 Shield reference RM1,169.10; middle 2 TB DIY RM1,502.99 or E82 RM1,599; higher-capacity 4 TB E82 RM2,519, T7 Shield RM3,150 or premium 990 Pro DIY RM3,630.66. The cheaper quotes may be sold out or incomplete, and stock never changes merit. Choose 4 TB for demonstrably retained growth or retention headroom, not merely because one day had 16 GiB host writes.
    These are dated references across sellers with different unresolved support routes, not an actionable cheapest-in-stock list.

    EX400U firmware and recovery qualification

    OfficialRecorded 2026-10-10
    Corsair's September 23, 2025 advisory identifies ULFM91.0 link-power-management exit failures causing frequent disconnects/non-detection on specified EX400U 1/2/4 TB SKUs and affected serial range AA2XB5090–AA2XB5260. Its Windows 10/11 reinitialization utility installs corrected firmware and erases the SSD. Check SKU, serial, current firmware and a backup before using that remedy. ULFM91.2 release notes dated January 8, 2026 provide a Windows-only update and address ThinkPad E14 Gen5 USB-C compatibility and CrystalDiskInfo health display. This is neither a population failure rate nor proof that every current unit is defective; the ranked intended configuration is correctly updated firmware. The latest notes do not certify unattended Mac mounting.

    EX400U exact 1 TB test and specifications

    ResearchRecorded 2026-10-10
    PC-WELT's exact EX400U 1 TB Windows test reports sequential read/write 4057/3595 MB/s, a 1000-MP3 copy at 1068/756 MB/s read/write, a 52 C shell and 2.3 W load, plus one connected-drive PC reboot hang. Those are not a 4K random test, a Mac result or a population failure rate. No exact 1 TB post-cache plateau was recovered. The separately retained 2 TB Windows test holds about 1.55–1.65 GB/s post-cache, while the retained exact 4 TB test has a 69 C case and test error. They are qualified family context for 1 TB, never measured 1 TB claims. Manufacturer CSSD-EX400U1TB specifies USB4, Mac compatibility, included cable and three-year limited warranty. Corsair describes native Phison PS2251-21, SMART/TRIM/garbage collection; the exact-capacity NAND, DRAM/HMB path and contractual TBW remain unresolved.

    ADATA's SE920-1TCBK sheet specifies USB4 40 Gb/s, five-year limited warranty, active retractable fan, mass 181.52 g and 5 V/3 A full power. APH's exact 1 TB sample on Windows/Intel TB4 uses ASM2464PD: cached ATTO peaks 2890/2740 MB/s read/write and uncached write 249.15 MB/s; none is a post-cache APFS result. Fan was audible and the slider could rattle. SSD-Tester exact 1 TB AS SSD 4K read/write is 44.53/74.04 MB/s; inconsistent CDM latency/IOPS are excluded. PCWorld's SE920 family Windows 450/900 GB transfers reach about 850 MB/s after cache, but the accessible prose does not prove the tested SE920 capacity: its 2 TB 990 Pro is the source drive. No exact 1 TB long-cache, Apple-silicon/APFS or unattended recovery dataset is asserted. NAND, DRAM/HMB and contractual TBW are undisclosed; speculative review TBW is not a warranty term.

    SL600 1 TB specification with 2 TB test extrapolation

    Lexar binds LSL600X001T-RNBNG to 1 TB, with USB 3.2 Gen 2x2, five-year limited warranty, aluminium body, sleeve and loop. Macs fall back to 10 Gb/s. No exact 1 TB post-cache or low-queue dataset was found. Tom's exact 2 TB family Windows 15-minute run holds around 1800 MB/s for 90 seconds then the mid-1400s; its 4617-file/50 GB mixed set is strong, with random reads behind LaCie and random writes near X10 Pro. PCWorld's separate 2 TB extended 900 GB write falls to about 700 MB/s after cache. These support qualified family-based editorial merit, not measured 1 TB performance. Capacity-unbound MacBook Pro results of 783/885 MB/s on exFAT and 876/907 on Journaled are not confirmed Apple-silicon/APFS tests. Manufacturer NAND, DRAM/HMB and TBW are not established; inferred TLC and speculative 600 TBW are not contractual facts. The 1 TB recommendation must retain this extrapolation beside it.

    Original Kingston SXS2000/1000G, UPC740617321340, is distinct from refreshed /1000GA. Manufacturer data describes five-year limited warranty and compact IP55 protection with sleeve. Tom's exact original 1 TB Windows sample uses DRAM-less SM2320 and Micron 96-layer TLC: around 103 GB at 1890 MB/s, then 214 MB/s average after cache during a 15-minute run, with no observed thermal throttling. Internal SMART 72 C and infrared shell 36 C are different measurements. SSD-Tester 4K Q1T1 read/write is 27.20/85.83 MB/s. Kingston stability firmware S9I00128 dated March 10, 2026 explicitly covers /1000G. Review BOM is not guaranteed for all later units; no portable TBW contract or M6/APFS uptime claim is asserted.

The tested family has three-bit NAND and DRAM-less architecture; portable contractual TBW is undisclosed. The 2 TB family review supports around 1000 MB/s sustained writes; retained exact 4 TB Windows 450 GB transfer and weak Q32T1 random writes remain distinct.

Peak gross host writes do not establish any net-growth forecast. Constant 16 GiB/day host writes for five years total 31.374736 decimal TB, 5.229123% of a 600 TBW contract; the same writes are 2.614561% of 1200 TBW and 1.307281% of 2400 TBW. Write amplification, calendar warranty, temperature, firmware and component failure are separate; low TBW use is not a lifespan guarantee.

    Model scoring input and rejected partial totals

    JudgementRecorded 2026-10-10
    Seventeen diagnostic scoring calls using Claude Sonnet 5.5 under the model-input EXTERNAL-SSD-3.0 rubric cost a reported total US$0.244685. Ten omitted one or more criteria; their service totals normalize over missing weights, so no diagnostic overall is adopted. Exact T9/X9 tests recovered afterward also correct the input's performance gaps. EXTERNAL-SSD-4.0 retains all weights and clarifies documentary design merit versus unknown exact-host acceptance. The author reassesses every entry and owns each complete criterion grade, not just the missing ones. Value and recency are reproducible formulas; the other grades are subjective evidence-backed assessments with stated extrapolation and confidence. No product catalog score or taxonomy is written. Initial inputs, model outputs, corrections and final complete arithmetic remain reproducible; source measurements are attributed to their authors rather than called Refer laboratory results.

    Buying advice and scope of the ranking

    JudgementRecorded 2026-10-10
    The 1 TB ranking leads, but a high reference-price score does not imply a sold-out drive can be bought now. Lexar's affordable 1 TB reference uses explicitly labelled 2 TB family performance; T7 Shield has exact 1 TB long-write evidence and a separate higher-priced listed offer. ADATA is a listed 1 TB USB4 alternative with fan and incomplete exact post-cache/Mac evidence. OWC/990 Pro offers a replaceable high-performance path at a much higher incomplete parts cost; the closest named Mac/APFS test is the retained 4 TB build, not the 1 TB build. Corsair requires firmware/batch checking; E82 requires continuous USB4 power and is 2/4 TB, not 1 TB. Retain every larger entry and old dated offer as history. Buy a complete supported configuration only after confirming the actual quote, local service and Mac acceptance. Availability is a filter and never changes scores or original capacity ranks.

     Ranked revision and retained capacities

     JudgementRecorded 2026-10-10
     The user requests visible ranks and /100 scores, a stronger 1 TB focus, and retention of the existing larger-capacity work. The revised field has eight 1 TB, five 2 TB and four 4 TB complete configurations, 17 total. Every previous main entry is retained. Ranks are within capacity, with 1 TB first, using EXTERNAL-SSD-6.0. The preceding public version was a seven-entry unranked comparison; its observations and research remain history, not the current merit order. After the independent challenge, the 1 TB order is provisional; DIY recency uses oldest-component parts age, uniformly across all pairs. Later-component build-possible-by remains a separate fact. Listed buying choices lead the short page. After the second challenge, prebuilt drives with only another-capacity post-cache evidence use the same conservative sustained/design baseline of 50: SL600 1 TB, EX400U 1 TB and E82 4 TB. All weights and price/age formulas are retained; this changes grades and orders without fitting weights to a preferred winner.

     Complete editorial scoring method

     JudgementRecorded 2026-10-10
     EXTERNAL-SSD-6.0 is active, agent-set under standing authorization. Weights: connection/data path 0.20; sustained transfer/thermals 0.17; mixed/small IO 0.10; Mac/platform fit 0.12; endurance/support 0.10; RM value 0.13; physical design 0.08; release recency 0.10. Sum 1.00. The v2/v3 weights are unchanged. Final author-owned ratings assess sourced design, documented support and labelled empirical tests. They are editorial merit estimates, not measured failure probabilities or uptime certification. Unknown exact M6 sleep/wake and encrypted APFS results remain acceptance conditions, not fabricated observations. A documented single-cable compatible path receives 60 for connection merit; the OWC Apple-silicon diagnostic path 65; E82's explicit continuous-power condition 55; EX400U's official firmware recovery/host-fault qualifications 45. None receives an excellent connection grade. Value is min(100,100 times the lowest exact reference RM/TB among ranked entries of the same capacity divided by the candidate's RM/TB); a sold-out dated price is valid price evidence. All eight criteria contribute at their original weights; no missing-criterion normalization or availability/ownership points. Family/component performance extrapolation remains explicit, and small point differences do not establish statistically measured superiority. After the independent challenge, the 1 TB order is provisional; DIY recency uses oldest-component parts age, uniformly across all pairs. Later-component build-possible-by remains a separate fact. Listed buying choices lead the short page. After the second challenge, prebuilt drives with only another-capacity post-cache evidence use the same conservative sustained/design baseline of 50: SL600 1 TB, EX400U 1 TB and E82 4 TB. All weights and price/age formulas are retained; this changes grades and orders without fitting weights to a preferred winner.

     How release recency is calculated

     CalculationRecorded 2026-10-10
     EXTERNAL-SSD-6.0 recency is min(100,max(0,round(100*(1-age_days/(2*cycle_days))))), with 1120 cadence days and check date 2026-10-10. Single-brand cadence is a proxy, not an industry median. Exact documented dates and sale/order-by bounds are distinguished. DIY parts age uses the oldest documented component uniformly after the challenge; the later 2023-12-07 enclosure date remains build-possible-by, not scored age. A later sale-by bound can overstate recency if an earlier sale is later found. Assembly does not reset either component clock.

     Sensitivity and close score orders

     Reproduced sensitivity of the complete editorial assessments: ["V6 keeps the v5 oldest-component clock uniformly for DIY. Only SL600 1 TB, EX400U 1 TB and E82 4 TB sustained grades move to the same conservative baseline 50. Baseline 1 TB order: 1M2 + 990 Pro 62.7 > SL600 62.5 > T9 60.9 > T7 Shield 60.4 > 1M2 + SN850X 59.8 > SE920 56.3 > EX400U 53.7 > XS2000 48.1. Build-possible-by remains separately 2023-12-07.", "The v6 baseline is provisional: grades are calibrated editorial judgments, not exact-1-TB lab results or demonstrated statistical superiority. SL600 family evidence and its sold-out reference-price advantage need particular caution.", "The separate RM773 T7 Shield 1 TB buying offer changes 60.4 to 57.5/100 (about 2.95 points), moving from rank 4 to 5; its RM545 dated reference is not currently purchasable.", "Restoring the optimistic v5 SL600 sustained grade to 65: SL600 65.0 > 1M2 + 990 Pro 62.7 > T9 60.9 > T7 Shield 60.4 > 1M2 + SN850X 59.8 > SE920 56.3 > EX400U 53.7 > XS2000 48.1.

The proxy cadence and sold-out reference prices are modelling choices, not hidden confidence.

All same-capacity value scores were recomputed, with no stock points. Small differences can change order under these assumptions and should not decide a purchase alone.

     Independent challenge and author adjudication

     JudgementRecorded 2026-10-10
     Three read-only Claude Code second-opinion reviews challenged EXTERNAL-SSD versions 4, 5 and 6; all returned unsafe as-is, not PASS. The author accepted corrections to DIY component age, portable family-based sustained grades, price and grade sensitivity, actual buying-offer visibility, test/cache attribution, capacity order and short-page qualifications. The final reviewer still disputes positive component-based grades for untested complete external builds, the modest OWC connection grade and ordinal separation of close totals. The author permits explicitly labelled same-capacity NVMe/enclosure component merit without claiming measured external throughput, retains the predeclared cost-efficiency scale and exact-rational ordering, and labels the Mac-use ratings provisional. Final author decision: PASS for the qualified provisional editorial ranking; this is separate from and does not relabel the independent verdicts. The sealed briefs, original replies and full author adjudication are retained as evidence. No physical-host or exact-pair post-cache acceptance is claimed.
