Kingmax has announced the release of the PQ4480 “entry-level” SSD. This is an M.2 SSD with a PCIe Gen4 x4 interface. However, the possibilities of PCIe Gen4 in this case are far from being fully used.
The drive is available in 250 GB, 500 GB and 1 TB. All three options provide sequential read speeds up to 3600 MB/s. The 250 GB variant delivers 1200 MB/s sequential write speeds and up to 150,000 read IOPS and 300,000 write IOPS random access performance. The 500 GB variant achieves a sequential write speed of up to 2300 MB/s and a maximum random access performance of 300,000 read IOPS and 350,000 write IOPS. Finally, the 1 TB variant is capable of sequential write transfers of up to 3,000 MB/s, and its performance reaches 400,000 and 450,000 IOPS in read and write mode, respectively.
A 250 GB SSD resource is declared equal to 150 TBW, a 500 GB SSD is 300 TBW, and a 1 TB SSD is 600 TBW. The drives come with a three-year warranty. The manufacturer does not name prices.
