SK hynix launches 3D NAND QLC consumer SSDs under the Solidigm brand

Solidigm, founded by SK hynix after buying Intel’s NAND flash business last year, has introduced the P41 Plus PCIe 4.0 x4 series consumer SSDs. The family includes three models – with a capacity of 500 GB, 1 and 2 TB.

Solidigm P41 Plus drives are based on Silicon Motion SM2269XT controllers, which have no DRAM buffer memory and 144-layer 3D NAND QLC flash memory chips. The controller claims to support the PCI Express 4.0 interface and conform to the NVMe 1.4 protocol specifications. The drives are available in the M.2 2280, M.2 2242 and M.2 2230 formats. SSD versions in the latter two formats are sold by OEMs in laptops and standard PCs.

The P41 Plus series drives are said to have sequential read speeds of up to 4125 MB/s and sequential write speeds of up to 3325 MB/s. At the same time, the performance of new products reaches 390,000 IOPS in random write and 540,000 IOPS in random read.

One of the main features of the new Solidigm P41 Plus series drives is the Synergy software offered for them, which increases the speed of random reads and writes when the SLC cache is full, the volume of which is 75, 150 and 2 TB models with 512 GB, 1 and 2 TB or 300 GB.

For the younger model, the company claims a resource of 200 TB of rewritten information, for models of 1 and 2 TB – 400 and 800 TB of rewritten information, respectively. The manufacturer grants a 5-year guarantee on new goods. The company does not name the price of the drives. However, based on the characteristics, it is not expected to be high.
