The PNY CS900 120GB is an entry-level SSD storage from PNY, an American PC peripheral manufacturer. The storage unit comes in the 2.5-inch form factor providing speed up to 6 Gb/s. The unit I have with me is SATA III 120GB storage. In general, the PNY CS900 series engineered to be cost effective storage replacement for your existing storage.

Upon unboxing the storage unit, you only will get a unit of PNY CS900 120GB SSD. Sadly, there are no additional screws given. I would be recommending you have to have four-extra screws to properly mount the SSD in your PC case.

Benchmark Analysis

My benchmark PC has the following specification:

ProcessorIntel(R) Core(TM) i5-8400 CPU @ 2.80GHz 2.81GHz
Operating SystemWindows 10 Pro (Build 2004)
System Type64-based processor

In order to make sure the I able to get a good benchmark reading, I’ve make sure that the disk is healthy and optimized it to produce a peak storage reading.

I’ve used a few free disk benchmark tools to measure the read and write speed of PNY CS900 120GB. The first tool used is the CrystalDiskMark Standard Edition.

Based on the result above, the PNY CS900 produce a better read and write rate. The benchmark process was done three times to get a solid result before recorded down. I am really surprised to the result since the storage unit is an entry level, yet outclassed the performance of an entry level gaming SSD.

The next benchmark tool used is AS SSD Benchmark to analyse and record the performance of the storage unit, if the result produced may differ compared to the result obtained in Figure 6 above. However, the PNY CS900 still outperform the Galax Gamer 120GB.

When it comes to acceleration time performance test, it is really important to see a true performance of a storage unit, especially SSDs. Looking at Figure 7, the acc.time of PNY CS900 is lower than the Galax Gamer 120GB. If a higher read and write speed indicates a good characteristic of an SSD, the result produced by the acc.time should be lower. In other word, lower is better.

Looking at the overall scores plotted on Figure x on above, the PNY CS900 has a higher score compared to Galax Gamer L SSD. Being a cheaper in price, the PNY CS900 performs better than its competitor.


Figure 10: PNY CS900 Review - Conclusion
Figure 10: PNY CS900 120GB Review – Conclusion

To conclude the review, the PNY CS900 120GB is a decent storage. The real-world transfer rate in between the SSDs are 1.81GB/s while the transfer rate in between the HDD to SSD is 184MB/s – 200 MB/s. The SSD is suitable for standard use such as running an operating system or being a dedicated virtual-machine playground, thanks to its excellent read and write speed. I can certainly recommend the SSD to budget users. If you’re expecting for a higher read and write throughput, it is better to invest on a PCIe NVMe SSD instead.
