Pros & Cons

Pros

  • ✓ Up to 535MB/s read and 500MB/s write over SATA III
  • ✓ Backwards compatible with older SATA II 3GB/sec controllers
  • ✓ 3D NAND with no moving parts, so no mechanical failure points

  • ✗ Sequential figures are peak, not sustained large-file write speeds
  • ✗ 2.5-inch form factor needs a bay and cable, unlike M.2

Manufacturer description

The PNY CS900 250GB is a straightforward SATA III upgrade path for any laptop or desktop still running a mechanical hard drive. Built on 3D NAND in the standard 2.5-inch form factor, it delivers up to 535MB/s sequential read and 500MB/s sequential write speeds over the 6GB/s SATA interface, which is enough to cut OS boot times and application launches down from the minute-long waits typical of spinning platters. With no moving parts, the CS900 draws very little power, runs silent, and removes the mechanical failure points that make an aging HDD a liability in a daily-driver machine. At…

Frequently Asked Questions

How fast is the PNY CS900 250GB?

PNY rates it at up to 535MB/s sequential read and 500MB/s sequential write, which is at the practical ceiling of the SATA III 6GB/s interface.

Will this SSD work in an older computer?

Yes. The CS900 is backwards compatible with SATA II 3GB/sec, so it works in older systems, though throughput will be limited by that older interface.

Is 250GB enough space for Windows?

It is sized as a boot drive. Windows plus core applications fit comfortably, but plan on a second drive for large game libraries or media files.

What warranty does PNY offer on the CS900?

PNY states the CS900 supports up to a 3-year warranty. Check the product listing for the current terms that apply to your region.

Is this a good upgrade from a hard drive?

That is its stated purpose. PNY positions the CS900 as a cost-effective HDD replacement.
