OCZ: Super-Affordable Core Series SSDs Use MLC Flash, Will Reach 256GB
July 2nd, 2008 by Jeffrey L. Wilson
When memory-manufacturer OCZ announced its new “Core Series” line of low-cost, high performance solid-state drives, our resident storage nuts went bonkers with the prospect of securing wallet-friendly SSDs. Naturally, our inquisitive minds began to wonder how OCZ could crank out 32GB, 64GB, and 128GB solid-state drives for $169, $259, and $479, respectively, while maintaining read/write speeds of at least 120MBps/80MBps.
So we spoke with OCZ CEO Ryan Petersen about these potentially game-changing SSDs. In our interview, Peterson confirmed that the drives are made Multi-Level Cell (MLC) flash, and that they will be available for purchase July 12th or shortly thereafter.
Because MLC flash memory has a reputation for being less reliable than SLC, we asked OCZ a follow-up question about estimated number of write cycles to failure, and we’re still waiting for an answer beyond the 1.5 million hour MBTF number quoted in their specs. Our interview is below.
How did you manage to get the prices so low on the Core Series?
The biggest barrier to SSD adoption has been price, and we have been exploring ways to bring down the price without sacrifices in performance. With the Core Series SSD drives are able to take advantage of lower cost multi-level cell technology in a multiple channel configuration and when coupled with new proprietary firmware we can maximize the speed while simultaneously lowering the cost. The previous issues with using MLC technology in SSD limited the write speeds, reducing the overall performance to that below current high speed HDDs, with the core series this is no longer an issue.
Does OCZ manufacture its own flash memory chips? If not, who is the supplier?
OCZ, while not a foundry, is able to leverage our existing relationships with partners, in this case Samsung to bin flash ICs for the highest possible write and read speeds.
