Solidigm came into being at the end of 2021 as a result of SK Hynix's acquisition of Intel's SSD business and the Dalian NAND flash facility in China. The P41 Plus is the first Solidigm-branded SSD to be launched and is aimed at the ever-growing and increasingly competitive value end of the PCIe Gen 4 market.

The P41 Plus is built around a 4-channel controller and QLC NAND. The controller is a Silicon Motion SM2269XT. Built on a 12nm process using a dual-core ARM R8 CPU, the DRAM-less SM2269XT (it uses Host Memory Buffer technology) uses a 7mm x 11mm package and is the company's mainstream PCIe Gen4 controller. It supports four 1,600MT/s NAND channels and can be used with either TLC or QLC NAND.




Solidigm rates the Sequential performance of the 1TB drive as up to 4,125MB/s for reads and up to 2,950MB/s for writes. Using both the ATTO (3,860MB/s reads, 2,780MB/s writes) and AS-SSD (3,530MB/s reads, 2,580MB/s writes) benchmarks we couldn't confirm those official maximums. However, using the default CrystalDiskMark 8 test we could confirm the official figures with test results of 4,191MB/s and 2,966MB/s for reads and writes respectively.

When it comes to 4K random performance the 1TB P41 Plus is officially rated as up to 225,000 IOPS for reads and 520,000 IOPS for writes. With our 4-threaded tests, we could confirm the random read figure with a test score of 226,160 IOPS but fell well short of the official write figure with a best test result of 247,641 IOPS. Using the Peak Performance profile in CrystalDiskMark 8 we could once again confirm the official read maximum with a test result of 226,615 IOPS (default-test) but once again fell short of the maximum official write figure but this time not by much with a test result of 514,222 IOPS (0 fill test).

We found the 1TB Solidigm P41 Plus on CCL Computers for £70.20 (inc VAT) HERE.

Pros:

• Solid Sequential performance.
• Solidigm Storage Tool.
• Competitive Pricing.

Cons:

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

KitGuru says: Solidigm's first branded Gen4 drive performs pretty well for the market segment it is aimed at and is competitively priced and it needs to be as it's entering a segment that is rapidly becoming very competitive.
