Crucial P5 Plus 1TB SSD Review

Rating: 8.0.

Among the well-known brands offering PCIe 4.0 SSD since day one, one name was noticeable by its absence… but that has changed with the arrival of Crucial's P5 Plus, a drive aimed more at offering value for money than bleeding-edge performance. We review the 1TB model, priced at just under £160.

Crucial's P5 Plus line-up consists of just three capacities (at the time of writing); a 500GB entry model, 1TB (the drive we are looking at here) and a flagship 2TB drive. The P5 Plus uses a combination of a Micron controller (labelled DM02A1) and their latest 176-layer 3D TLC NAND. The drive also supports hardware AES 256 full disk encryption including support for the TCG OPAL 2.0 specification.

The P5 Plus is officially rated as up to 6,600MB/s for Sequential reads for all three drives, with the 500GB drive getting a 4,000MB/s Sequential write rating while the 1TB and 2TB drives are quoted as up to 5,000MB/s. We couldn't find a figure for random read/write performance on Crucial's website but a quick search online came up with figures of up to 630,000 IOPS for random reads and up to 700,000 IOPS for random writes.

The official TBW endurance rating for the 1TB drive is 600TB. For the 500GB drive, it's 300TB and the 2TB drive, 1200TB.
