Benchmarks

Data Transfer Performance

Those were the days! These days you can barely do anything with maximum transfer rates of some 8.6 MB/s (Quantum UltraDMA/33). The first truly remarkable improvement in performance was brought about by the first generation of IDE hard drives featuring 7,200 rpm and UltraDMA/66.

Burst Performance

This clearly shows what each interface has to offer. While the first two UltraDMA/33 drives had access times of some 30 MB/s, the maximum (reading from the hard drive's cache) jumped to over 50 MB/s with Seagate's Barracuda ATA (UltraDMA/66), and today's UltraDMA/100 hard drives feature an impressive 86 MB/s. This upper limit will soon be pushed significantly, with the introduction of Serial ATA.
