Solidigm P41 Plus 2TB SSD Review

Rating: 8.0.

Late last year we took a look at the 1TB version of Solidigm's entry-level Gen 4 SSD, the P41 Plus. Now it's the turn of the 2TB flagship drive, coming in at £115 here in the UK. Can it do enough to stand out in a fiercely competitive market?

The 2TB P41 Plus is the flagship model of a three-drive family along with 512GB and 1TB options. The P41 Plus uses a combination of a Silicon Motion SM2269XT controller (4-channel PCIe Gen 4 x4) and Solidigm 144-layer 3D QLC NAND. It's a DRAMless design using Host Memory Buffer technology instead.

Officially the 2TB drive is rated as up to 4,125MB/s and 3,325MB/s for Sequential read/write performance respectively. The entry-level 512GB model is rated at up to 3,500MB/s for reads & 1,625MB/s for writes. The 1TB drive has the same 4,125MB/s read figure as the 2TB drive with a write speed of up to 2,950MB/s.

The official 4K random performance figures for the 2TB drive are up to 390.000 IOPS and up to 540,000 IOPS for reads and writes respectively. The 1TB drive has figures of up to 225,000 IOPS for reads and up to 520,000 IOPS for writes. The 512GB drive makes do with 115,000 IOPS reads and 390,000 IOPS writes.

Solidigm quotes power consumption figures for the drive of active 80mW and active 80mW idle. The endurance of the 2TB drive is rated at 800TBW and Solidigm back it with a 5-year warranty.
