With the rest of the system, the MSI Spatium S270 interfaces using a SATA 6 Gbps connection. The SSD controller is the PS3111-S11-13 from Phison, a DRAM cache is not available. MSI has installed 64-layer TLC NAND flash on the Spatium S270, the flash chips are made by SpecTek. Please note that this SSD is sold in multiple variants with different NAND flash or controller, which could affect performance, the "Notes" section at the end of this page has more info.

Copying data out of the SLC cache (folding) completes at 50 MB/s. The Spatium S270 is rated for sequential read speeds of up to 500 MB/s and 450 MB/s write; random IO reaches 55K IOPS for read and 80K for writes.
At its launch, the SSD was priced at 62 USD. The warranty length is set to five years, which is an excellent warranty period. MSI guarantees an endurance rating of 500 TBW, a relatively low value compared to other SSDs.
