The pSSDs use less-expensive, higher-capacity multi-level cell (MLC) NAND flash, as well as more reliable, traditional, but lower-capacity single-level cell (SLC) NAND, according to SanDisk. However, the company's currently available datasheet lists only MLC-based parts in the new pSSD product family. SLC-based parts appear to remain available in its older uSSD line, which shipped last Fall.

Like the low-cost Z-P230 SSD announced by Intel earlier this week, the new pSSDs use parallel ATA (PATA) interfaces to conserve power in mobile devices. Usable for both operating system files and user data, Sandisk's products support both Windows XP and Linux.

Availability

The pSSDs are being fabricated in Yokkaichi, Japan. SanDisk says it will share the output with its long-time partner, Toshiba Corporation. Availability is expected in August. Samples are on display at SanDisk's booth, M320, in Nangang Exhibition Hall.
