Israeli firm touts SSD endurance breakthrough


— 9:14 AM on June 16, 2010

An Israeli start-up claims to have developed technology that makes solid-state drives with multi-level-cell flash as reliable as their single-level-cell siblings. According to ComputerWorld, Anobit Technologies' Genesis SSDs have 20 times the endurance of typical consumer SSDs on the market right now—and they might not be much more expensive.

At the heart of the Genesis SSD is the Memory Signal Processor, which "boosts MLC NAND flash memory reliability through a special error-correction algorithm," the site says. Thanks to this processor, Anobit's 200GB Genesis drive can purportedly withstand 2TB worth of writes per day for five years. The 400GB Genesis can handle twice that.

Anobit's error-correcting algorithm might remind you of SandForce SSD controllers, which also include some special sauce to boost durability. On that topic, Forward Insights analyst Gregory Wong told ComputerWorld, "[SandForce uses] 24-bit/512-byte ECC hard coding. However, the fundamental issue is that the signal quality is declining, and Anobit's technology helps to get a 'cleaner' signal."

Genesis SSDs will be available in the two aforementioned capacities, 200GB and 400GB, with Serial ATA interfaces. ComputerWorld notes that an "external bridge" can give them Serial Attached SCSI or Fibre Channel connectivity. The drives are rated for top sequential read speeds of 220MB/s and write speeds of 180MB/s. That's not too shabby. Anobit Business Development VP Gilad Engel claims these SSDs will be "very competitive" with SLC-based enterprise offerings.
