Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info.

Copying data out of the SLC cache (folding) completes at 239 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The Viper VP4300 Lite is rated for sequential read speeds of up to 7,400 MB/s and 6,000 MB/s write; random IOPS reach up to 900K for reads and 700K for writes.
