Intel slashes SSD prices

July 23, 2009 –There are still some issues that need to be ironed out with solid-state disk (SSD) drives (e.g., reliability and endurance), but the biggest problem -- and gating factor to adoption -- has been the outrageous price of these devices.

One way to reduce prices is to use the less expensive multi-level cell (MLC) NAND flash technology, as opposed to the more expensive, reliable and durable single-level cell (SLC) technology. But at least for enterprise-class applications, that requires improvements in either controller and/or software technology (which I’ll blog about in an upcoming post).

Another way to reduce SSD prices is to go with a different manufacturing process. That’s what Intel announced this week for its X25-M (Mainstream) line of SSDs, which are admittedly designed primarily for desktops and laptops as opposed to enterprise arrays and applications.

Intel claims a 60% price reduction due to moving from a 50-nanometer manufacturing process to a 34nm process (smaller die size), and a quick price check seems to legitimize those claims.

For example, the 80GB X25-M SSD is channel-priced at $225 in 1,000-unit quantities, a 62% reduction from the original price of $595 a year ago. And the 160GB version is priced at $440, down from $945 when it was first introduced. Both of those SSDs come in a 2.5-inch form factor, with a 1.8-inch version, the X18-M, due in August or September.

Intel claims performance of “the same or better” compared to the 50nm predecessors, citing up to 6,600 I/Os per second (IOPS) on 4KB write operations, and up to 35,000 IOPS on read operations. The company also claims a 25% reduction in latency, to 65 microseconds.

Calculated on a cost-per-GB basis, SSDs are still way more expensive than traditional spinning disk drives, but SSD price wars should come as good news for users with the need for speed.
