Seagate Barracuda 7200.11 (1.5TB) review

Cheap and fast - the Seagate is an excellent high-capacity choice.

After the 2TB Caviar Green, this is the largest disk on test this month - and alongside the cavernous amount of space, provided as four 375GB platters, is a 32MB cache.

Cramming so much storage into such a small space didn't seem to slow down the Seagate. An average read speed of 99.1MB/sec and write speed of 84.5MB/sec placed the Barracuda second on our performance leader board. Access times weren't spectacular, though - a file-write seek time of 7ms lagged behind many of the other drives here.

Nevertheless, other benchmarks were encouraging. The burst speed of 231.3MB/sec was one of the best results this month, and an average sequential read speed of 104.9MB/sec was the fastest of all the Seagate drives.

Also impressive is the price: at 7p/GB the Seagate offers the best value this month. Couple this with its rapid performance and it's clear that this is one of the best high-capacity storage options available.
