Our take on the Plextor S2G M.2 2280 256GB SATA III TLC Internal Solid State Drive SSD PX-256S2G

The Plextor S2G is a 256GB M.2 2280 SATA III SSD built on TLC NAND, rated at up to 520 MB/s sequential read and 480 MB/s sequential write. It uses the older SATA interface over the M.2 slot, so it fits boards and laptops with an M.2 SATA key rather than NVMe. That makes it a modest upgrade for an aging machine, not a fast drive by current standards. Reviewers of this class of drive note that SATA M.2 models trail NVMe drives sharply in real-world transfer speeds, and TLC with a small cache can slow on long writes. It suits budget builds, secondary storage and reviving older laptops that cannot boot NVMe.

Pros
  • M.2 2280 form factor saves space and cabling
  • SATA III interface works in older M.2 SATA slots
  • Rated 520 MB/s read and 480 MB/s write, solid for SATA
  • 256GB is enough for an OS and core apps
  • Silent, shock-resistant, no moving parts
Cons
  • SATA M.2, not NVMe, so far slower than modern drives
  • TLC NAND with a small cache can slow on sustained writes
  • No DRAM cache on this tier, which hurts random performance
  • 256GB fills quickly with games and media
  • Not compatible with M.2 slots that only accept NVMe

Questions and answers

Is this drive NVMe or SATA?
It is SATA III over an M.2 2280 connector. It will not reach NVMe speeds and needs a slot that supports M.2 SATA.
Will it fit my laptop?
Only if the laptop has an M.2 2280 slot keyed for SATA. Many newer laptops accept only NVMe, so check the slot before buying.
Is it fast enough for gaming?
It loads games faster than a hard drive, but load times will be longer than on an NVMe SSD. Fine for older or budget systems.
How much can I store on 256GB?
Roughly the operating system, core apps and a handful of games. Plan on adding another drive for large libraries.
Does it need a heatsink?
No. SATA M.2 drives run cool and do not need the heatsinks used on fast NVMe drives.
Is it worth it over a 2.5-inch SATA SSD?
It performs about the same but saves the drive bay and cables. Choose it when you want a cleaner install, not more speed.
Where is the Plextor S2G M.2 2280 256GB SATA III TLC Internal Solid State Drive SSD PX-256S2G cheapest?
At Newegg, for $125.90, as of our latest check.
