New standards released for SSD evaluation, rating

By Mike Fischer on September 23, 2010, 8:45 PM
The JEDEC Solid State Technology Association announced today that its standards subcommittee has released two new standards for evaluating the reliability and endurance of solid-state drives. As more SSDs appear on the market, JEDEC hopes to use the new standards to "reduce market confusion, facilitate broad adoption and alleviate product quality and reliability concerns." This should be a benefit to consumers looking to compare SSDs from different manufacturers and make purchasing decisions that accurately meet their needs.

The new system will replace the previous method of testing "mean time between failure" with two new metrics: JESD218 Solid-State Drive Requirements and Endurance Test Method and JESD219 Solid-State Drive Endurance Workloads. Further class ratings will be set to differentiate between consumer and enterprise levels of performance. JEDEC's comprehensive approach to defining these performance factors "will go a long way towards enabling market confidence in SSDs, said Scott Graham, Vice-Chairman of the JC-64.8 flash memory subcommittee. A solid-state drive tutorial is planned for October 5th in San Jose to help with introducing and implementing the new standards.

With so many different companies now selling SSDs under their brand names and the amount of different controllers being used it can be quite difficult to choose a SSD I think.

So anything that helps to differentiate one drive from another is a good thing I think.

When I bought my 60GB OCZ Vertex 2 a couple of months ago I was looking at price primarily, then within my price range: TRIM support was a must, if performance numbers were similar (read and write speeds and IOPS) I then looked at warranty length and MTBF time.

I went with the OCZ Vertex 2 in the end as it had great performance numbers and the best warranty in my price range from the retailer I was using.

If these new standards of comparing SSD's are easy enough for Stan McNormalguy, then I sure hope to see some tests comparing SSD's using the methods described!

One of the main reasons I know so much about SSD's is because I almost religiously follow up on them with Anandtech. Reason being, he's very much on top of things in terms of Controllers, Firmwares, Speed, Bugs, etc. Either way, I refuse to buy an SSD until the price comes down. At least a ratio of $1 to 1 GB.
