The Intel SSD 510 Reviewby Anand Lal Shimpi on March 2, 2011 1:23 AM EST
A Word on Reliability
Marc Prieur has been around writing about hardware for as long as I can remember (think back to the old school Tom days). Late last year he published some particularly controversial numbers on his website: failure rates of various PC components according to a French etailer. Among the components were SSDs and the numbers are below:
|SSD Failure Rates - Hardware.fr|
I should add that the numbers Marc published were accurate (confirmed by some of the manufacturers involved), although they don’t paint the complete picture of world wide failure rates - they are an important sample to look at.
Other than Intel, none of the companies listed in that article were particularly pleased with the numbers.
I mentioned earlier that the 510 would go through Intel’s extensive validation testing, just like any other Intel product. Presumably this means that the SSD 510 should have similarly low failure rates in the field (unless there’s something horribly wrong with the Marvell controller that is). Compatibility should also be a strong point of the SSD 510 due to Intel’s stringent internal testing.
Note that I am separating reliability and compatibility from drive longevity. There’s typically a good correlation between high random write performance and low write amplification. The Intel SSD 510 doesn’t have particularly high random write performance, and in turn should suffer from fairly high write amplification in highly random workloads.
I’ve already proved in the past that at 5,000 p/e cycles there’s no cause for worry for a normal desktop user. The likelihood that you’ll wear out all of your NAND within the next 5 years is very, very low. However I will say that when faced with enterprise workloads you’re going to have to pay much closer attention to write amplification and spare area than you would on say a SandForce drive.
