Patriot Launches Viper VP4100 PCIe Gen 4 SSDs: Up to 5 GB/s

Patriot’s Viper Gaming division this week officially introduced its first PCIe 4.0 SSDs, several weeks ahead of schedule. The Viper VP4100 drives use Phison’s PS5016-E16 controller and generally resembles competing products. However, because of a custom firmware, the SSDs may differ a bit as compared to other E16 drives.

Available in 1 TB as well as 2 TB configurations and equipped with Phison’s PS5016-E16 controller as well as 3D TLC NAND memory, the Patriot Viper VP4100 is rated for up to 5000 MB/s sequential read speeds, up to 4400 MB/s sequential write speeds, as well an 800K peak read/write random IOPS. While the rated sequential write speed of the VP4100 is 100 MB/s lower than other drives based on the same controller, its rated random read/write performance is 50K IOPS higher, which looks like a reasonable tradeoff because random speeds usually have a more significant impact on end user experience.
