1TB PNY CS900 SSD Reviewed

Recent years have seen solid-state drives (SSDs) improve in speed and capacity, as well as falling in price significantly. 

It is now common to find SSDs in mainstream laptops and desktops as opposed to hard drives as the primary storage option. This technology was previously reserved for enterprise users and PC performance experts. In addition, adding an internal SSD to an older PC as a new boot drive remains an excellent, cost-effective upgrade. If you have been relying on spinning disk platters for your storage, this is one of the easiest ways to increase storage speed.

The PNY CS900 2.5-inch SATA-III (6Gb/s) solid-state drive (SSD) is PNY’s mainstream performance SSD. An excellent upgrade option from a traditional hard disk drive (HDD), this is an easy and cost-effective HDD replacement for your existing system, without sacrificing performance.

PNY rates the drive as capable of sequential writes at 515 MBps and sequential reads at 535 MBps. There is no significant difference in its performance ratings across the four capacities. A summary of its performance in each capacity:

480GB / 500GB550 MB/s500 MB/s
960GB / 1TB535 MB/s515 MB/s

The PNY CS900 is not meant to compete with other high-end SSD entries, but to provide a cost-efficient drive for mainstream users who will not be continuously writing large amounts of data. Consider a typical gamer, an office worker, or a light content creator who deals with smaller files. Individuals like them are the target audience for the CS900.

If you are still using 2.5-inch bays and SATA connectors for adding storage, then the PNY CS900 would be a great option for you. It makes the best use of an interface that had reached a point of relative stagnation years ago. PNY has carefully optimized the drive, enabling it to keep pace with high-end offerings, proving that SATA drives are not dead yet.

Final Thoughts

The drive may not be an ideal choice if you are a heavy data writer who pours massive amounts of data onto your drive every day (such as a video editing or constantly dealing with large files). Likewise, if you plan on using the SSD as a frequently written scratch disk in your NAS, this is not the best choice. However, if you are a lighter writer seeking a high-capacity, high-speed drive that does not come with the same high price tag as an SSD, this is an excellent option for you.
