Description
At 250 GB the drive is a boot volume and nothing else, and the numbers reflect that: read speed holds at the interface ceiling while write speed drops to 2300 MB/s because there are fewer NAND dies to write in parallel.
Key specifications
- Sequential 3500 MB/s read, 2300 MB/s write
- Random 250K / 550K IOPS (4K, QD32)
- 150 TBW endurance, 5-year limited warranty
- V-NAND TLC with DRAM cache
Where it fits
Thin clients, kiosk and signage machines, and repair stock for laptops whose original drive was this size. Not a capacity to quote for a general-purpose desktop in 2026.
Trade notes
Retail-boxed. Held in small quantity — the tier is being squeezed out of the market by 500 GB pricing, so confirm stock before committing to a build sheet.
