Ideal HDD replacement for mainstream PCs

The PNY CS900 500GB 2.5" SATA III internal SSD is built for consumers who want faster boot times and quicker application launches without moving parts. It uses 3D NAND and a SATA connector to fit standard drive bays in both laptops and desktops. Sequential read reaches 550 MBps and write reaches 500 MBps.

SATA III caps real-world throughput at 550 MBps

The SATA III interface limits maximum sequential transfer to 550 MBps read and 500 MBps write, so the drive cannot exceed these figures regardless of NAND speed. Random 4KB performance is rated at 500 megabits per second for both read and write. Idle power draw is 0.3W for cool, quiet operation.

Upgrades any 2.5" hard drive when boot speed matters

Replacing a mechanical HDD with this SSD removes moving parts, delivering up to 50 percent faster boot times and 30 times more robust non-volatile storage. The 512 cache helps sustain everyday workloads. MTBF is rated at 2000000 hours. The jump is worth it whenever an older system feels sluggish on startup or app loads.

Questions about this item

Is the 500GB capacity the only option in the CS900 series?

The CS900 series includes several capacities; the 500GB model shown here is the one currently available from this listing.

What do the 550 MB/s read and 500 MB/s write speeds mean for everyday use?

Those sequential speeds let the operating system and large files load noticeably faster than a mechanical drive, cutting boot time and application launch delays.

How does the SATA III interface affect real-world performance?

SATA III caps the drive at its rated 550 MB/s read and 500 MB/s write, so the CS900 delivers the full benefit of the interface without bottlenecking.
