Andrew Ku at Tom’s Hardware published a little gem of an article that discusses SSD performance relative to HDD performance in a very interesting and very sane way. Ku writes: “As a point of comparison, a file operation completes 85% faster on a low-end SSD than it does on a high-end hard drive, but there is only an 88% speed difference between a high-end hard drive and a high-end SSD. That why you shouldn’t let less aggressive benchmark results at the low-end deter you from making the switch. You don’t have to have the best SSD to get great performance relative to a hard drive.”
Ku’s article then places 39 SSDs in a 10-tier hierarchy to help you sort out the fastest performers (Tier 1) from the slowest (Tier 10). Just remember, even Tier 10 SSDs are really fast compared to HDDs.
