South Korean silicon bigwig Samsung has very quietly slipped out its latest 470 series SSDs into Japanese and EU markets. Featuring its latest controller, 30nm NAND and a standard 2.5in form factor, these drives can push up to 250MB/sec sustained read and 220MB/sec sustained write with 31k/21k IOPS for the 128GB and 256GB parts respectively.

The cheaper 64GB option sees a halving of its write performance to 110MB/sec and 11k IOPS, which is consistent with using half as much physical NAND.

Despite some reports of using a SATA 6Gbps interface, the Samsung website is unspecific.

TRIM comes as standard across the range, and Samsung claims 1.5 million hours MTBF (roughly 171 years of constant use) and a three year warranty of writing up to 20GB a day.

While it's evidently slightly slower (on paper) than the Crucial C300 and SandForce controllers out there, it's faster than the last series of Samsung controllers and could be a worthy replacement for the Indilinx mid-market SSDs.

Samsung could be hard pushed to shift them at RRPs of $199, $399 and $699 though, as this makes them more expensive than the Crucial C300 alternatives.
