Crucial has clearly put a lot of time and effort into their new P5 SSD. Instead of using an off the shelf solution from a company like Phison or Silicon Motion, this new drive has been engineered from the ground up. Everything from Micron's cutting-edge DM01B2 controller, with its innovative technologies, to the 3D TLC NAND flash has been developed in house. Combine all this with a PCIe Gen3 x4 NVMe 1.3 interface and you have drive that is capable of delivering the performance, reliability and features that gamers and creative professionals are looking for. The P5 flew through our sequential transfer rate tests, reading at speeds as high as 3,504 MB/s and writing at more than 3,252 MB/s. The drive's performance wasn't nearly as impressive when doing random writes. Nevertheless, it was able to produce more than 165,000 IOPS at low queue depths.
