KINGMAX today unveiled the AX448 line of M.2 NVMe SSDs. These drives come in high capacity variants of 1 TB, 2 TB, and 4 TB, and take advantage of the PCI-Express 4.0 x4 host interface, and NVMe protocol. The 1 TB variant offers sequential transfer rates of up to 4500 MB/s reads, with up to 1750 MB/s writes. The 2 TB variant does up to 4700 MB/s reads, with up to 3300 MB/s writes. The 4 TB variant tops the charts with up to 4800 MB/s reads, and up to 3450 MB/s writes, at least on paper. Endurance of the three variants is rated at up to 200 TBW for the 1 TB variant, up to 400 TBW for the 2 TB variant, and up to 800 TBW for the 4 TB variant. The drive is likely using QLC NAND flash, given these endurance numbers, although the company didn’t mention the controller or NAND flash type.
