KINGMAX Unveils PQ4480 M.2 NVMe Gen4 SSD

KINGMAX today unveiled the PQ4480, an interesting “entry-level” M.2 NVMe SSD. While it features a PCI-Express 4.0 x4 host interface, it doesn’t really utilize that kind of bandwidth, and should offer nearly-identical performance with both PCIe Gen3 and Gen4 M.2 slots. While the company doesn’t mention the controller + NAND flash combination in play, we predict this to be a Phison PS5019-E19T PCIe Gen4 DRAM-less controller, paired with 3D TLC NAND flash memory.

The PQ4480 comes in capacities of 250 GB, 500 GB, and 1 TB. All three capacity variants offer sequential read speeds of up to 3600 MB/s. The 250 GB variant writes at up to 1200 MB/s and has 4K random access speeds of up to 150k/300k IOPS reads/writes, the 500 GB variant up to 2300 MB/s with up to 300k/350k IOPS, and the 1 TB variant up to 3000 MB/s, with up to 400k/450k IOPS. Endurance is rated at 150 TBW for the 250 GB variant, 300 TBW for the 500 GB variant, and 600 TBW for the 1 TB variant. KINGMAX is backing these drives with 3-year warranties. The company didn’t reveal pricing.
