Benchmarks I
The widely used CrystalDiskMark is a perfect showcase for PCIe Gen 4's headline figures, with our own results confirming that Seagate's quoted 5,000MB/s read and 4,400MB/s write are very close to the mark.
FireCuda 520 is easily the quickest M.2 drive we've tested to date, and for benchmark fiends, the advantage of PCIe Gen 4 is unmistakable. Do also be aware that Gen 4 drives are backward compatible; with the same drive attached to our regular Intel test platform via PCIe Gen 3 x4, we managed sequential read and write speeds of 3,481MB/s and 3,358MB/s, respectively. Handy to know if you're planning to use the drive on an existing rig before upgrading to PCIe Gen 4 at a later date.
