SanDisk Extreme PRO Portable SSD 1TB: problems, parts and running costs
Checked: 2026-10-24
Summary
The SanDisk Extreme PRO Portable SSD V2 is a fast, pocketable 1 TB USB-C drive with a 5-year warranty, but the Extreme/Extreme PRO line has a documented, unresolved data-loss and unmountable-drive failure mode that persists even after firmware updates. Treat it as high risk for irreplaceable data and keep a 3-2-1 backup. Value is poor for irreplaceable data at any price.
Common problems and fixes
- No free data recovery offered — Western Digital did not proactively offer free data recovery for affected units, per Ars Technica and The Verge. The manufacturer page sells a Data Recovery Plan (Ontrack) as a paid add-on. [1][4][5]
- Firmware fix of limited scope — the May 2023 firmware update covered only specific capacities (4 TB Extreme; 4/2/1 TB Extreme PRO; 4 TB My Passport) and described the defect only as “unexpectedly disconnect from a computer,” which understates the reported total data loss. Units outside those capacities, and post-update units, still failed. [4][5]
- Performance claim unverified — no independent instrumented test of the V2 was found; the ~2,000 MB/s figure rests on the manufacturer’s “nearly 2x” claim and the prior generation’s tested ~1,050 MB/s. [1][2]
- No activity or power indicator LED — the prior generation has no LED, so transfer and power status are not visible. [3]
- Short included cables — the prior generation ships with ~1 ft USB-C to USB-C and USB-C to USB-A cables. [2][3]
Parts and consumables
No replaceable parts or consumables reported.
Yearly running cost
No recurring subscription or consumable cost is reported in the sources. The only ongoing cost is electricity, which the sources do not quantify, so a yearly figure cannot be computed. A 3-2-1 backup strategy effectively requires additional drives, but that is a one-time purchase rather than an annual cost. [4]
When it is a good buy
No other store price thresholds are given in the sources read here, so no buy-at price can be stated. On the documented reliability record, value is poor for irreplaceable data at any price; only consider the drive for disposable or replicated data at a low enough price to treat it as expendable. [4][5] No named alternatives appear in the sources; buyers needing a trustworthy portable SSD should look elsewhere until a fixed hardware revision is confirmed. [4][5]
