Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • Non-heatsink (YM8) and heatsink (M8) part numbers differ in thickness; check slot clearance.
  • DC2000B is the data-center line; Kingston DC600M/DC600R are SATA/SAS data-center drives, not this model.

Why people pick it

  • Hardware power-loss protection with onboard power caps, rare at this price class and valuable for a boot drive
  • Steady-state 4K random-write consistency is what it is rated for: data-center boot and caching duty, not burst consumer workloads
  • M.2 2280 non-heatsink form factor fits standard M.2 slots on server boards and NAS motherboards

Know before you buy

  • 240GB sequential write is only 400 MB/s (480GB/960GB models are faster); this capacity is a boot/caching drive, not bulk storage
  • Thermal throttling on sustained writes without the heatsink version in tight enclosures
  • TLC endurance of 175 TBW over 5 years is modest compared with higher-capacity data-center drives
