The P41 Plus is the first Solidigm-branded SSD product line to be launched, we looked at the 1TB drive late last year, and this time we take a look at the 2TB flagship drive.

The P41 Plus uses a combination of a Silicon Motion controller and QLC NAND and is a DRAM-less design (it uses Host Memory Buffer technology). The controller in question is Silicon Motion's SM2269XT, their mainstream PCIe Gen4 controller. A 4-channel controller built on a 12nm process using a 7mm x 11mm package, it uses a dual-core ARM R8 CPU supporting four 1,600MT/s NAND channels and can be used with either TLC or QLC NAND.  The NAND that the P41 Plus uses is Solidigm's own 144-layer 3D QLC NAND.

The 2TB P41 Plus is rated officially as up to 4,125MB/s and 3,325MB/s for Sequential reads and writes respectively. Using the ATTO benchmark, the best test result figures we saw from the drive; 3,810MB/s reads and 3,100MB/s for writes are shy of the official maximum. Switching over to the CrystalDiskMark benchmark we could confirm the official figures with default test results of 4,139MB/s for reads and 3,336MB/s for writes.

When it comes to 4K random performance the 2TB P41 Plus is officially rated as up to 390.000 IOPS for reads and 540,000 IOPS for writes. With our 4-threaded testing producing best test results of 367,252 IOPS for reads and 298,318 IOPS, we fell short of those official maximums. We got closer to both using the Peak Performance profile in CrystalDiskMark 8 with a best-read figure of 376, 009 IOPS (default test) and 509,872 IOPS for writes (0 fill test).

We found the 2TB Solidigm P41 Plus on Ebuyer for £112.98 (inc VAT) HERE.

Pros

• Solid sequential performance.
• Solidigm Storage Tool.
• Competitively priced.

Cons

• DRAM-less design.
• Not the fastest Gen4 drive we've seen.

KitGuru says: As we said with the 1TB P41 Plus, Solidigm's 2TB version of the drive performs reasonably well for the market segment it is aimed at. Solidigm has given it every chance by giving it a competitive price tag.
