As for performance, the top-spec 32GB drive reportedly rivals desktop hard drives with 90MB/s sequential reads and writing at 70MB/s. The smaller 16GB and 8GB versions can also read data at 90MB/s, but their write speeds drop to 45MB/s and 25MB/s respectively. These low-density SSDs all use the same 3Gb/s SATA II controller as that being used on Samsung’s recently introduced MLC-based 128GB SSD.
Although no details have been announced on pricing, you can expect these drives to be cheap in comparison to SLC-based SSDs. The three new SSDs are sampling now, with mass production set to start in September.
