Addlink today refreshed its S20 line of SATA SSDs with the new S20M series. The refreshed lineup uses 96-layer 3D TLC NAND flash memory, and a Maxiotek MAS080X controller replacing the Phison S11-series controller on the original S20. The 2.5-inch, SATA 6 Gbps drive comes in 256 GB, 512 GB, and 1 TB capacities, which offer varying performance. There is no 120-128 GB variant in the series. The 1 TB variant offers sequential reads of up to 560 MB/s, and up to 500 MB/s sequential writes. The 512 GB variant offers up to 550 MB/s reads, with up to 500 MB/s writes. The 256 GB variant does up to 510 MB/s reads, and up to 400 MB/s writes. Addlink claims increased endurance and MTBF over the S20, although it didn't specify numbers. The company didn't mention pricing, although availability is expected by late-May.
