We looked at several Seagate Barracuda 7200.10 drives to get down to the performance nitty-gritty. In doing so, we found that there is hardly any difference between two drives that only differ in their cache sizes: 16 MB cache has no significant advantage over 8 MB across our benchmark suite, and this applies both to Serial ATA and to UltraATA drives. We would have expected that at least the SATA drives would show some degree of benefit, but in the case of the 7200.10 family, 16 MB cache is a waste of money if you have a cheaper 8 MB alternative. At the same time, 16 MB cache doesn't hurt either if the price is about the same...
