Intel has revealed some sweet numbers for their ‘refresh’ for the Postville, and they call it the Postville Refresh. For your info, the current X25-M G2 carries the Postville codename. The new drive will use 25nm IMFT Flash, which probably means twice the capacity at the same price. Even though Intel is sampling the 25nm MLC NAND, it is not certain whether the drive itself will be available this year. Will probably arriving in first quarter of next year. The expected capacity ranges from 40GB (X25-V) all the way up to 600GB.

Intel is listing the new X25-M as being 3Gbps SATA only. The SATA employment has been updated to support ATA8-ACS so it’s possible we may see official 6Gbps support once Intel has a chipset with native support. The third generation X25-M will probably have a huge write amplification, as Intel upgraded the total 4KB random writes spec from 7.5TB – 15TB on the G2 to a much higher range of 30TB – 60TB.

The new X25-M will be available in both 1.8” and 2.5” versions. The 1.8” drive tops out at 300GB; you’ll need the 2.5” form factor for 600GB.

Intel is also planning to launch their first Intel Enterprise SSD to use MLC flash, which is called the X25-E and due out in Q1 of 2011. It uses a modified version of the 25nm process that trades data retention for longevity. The X25-E will be 2.5” only.
