Today, Intel released the SSD 510 MLC drives with an official IOPS rating of up to 20,000 read (4k random) and 8,000* write (4k random) and sequencial file read/write performance of up to 500/315 MB/s. To take full advantage of these SSDs you need full SATA 6 Gb/s (SATA 3.0) support.
The Intel SSD 510 is available in 120 GB and 250 GB versions. Retail units are already available in many outlets online, and expected to start shipping at the time of writing.
You’ll have to shell out around $315 US for the 120 GB unit or $615 US for the bigger 250 GB unit (current price at time of writing at Newegg).[notice]* Actual write performance is up to 12,000 write operations per second according to early unofficial benchmarks.[/notice]
