Seagate Barracuda 7200.11 (750GB) review
Unpredictable performance and poor value ruin this Seagate.
Seagate varies its specifications more than any other manufacturer. The 640GB Barracuda boasts two platters and a 32MB cache; this 750GB drive has four 188GB platters but only 16MB of buffer, resulting in predictably reduced performance.
Average read and write speeds of 82.8MB/sec and 77.4MB/sec respectively saw the 750GB Barracuda lurching towards the bottom of our results table, and seek times of 17ms and 5ms were also average.
Its burst speed of 114.2MB/sec was half that of the fastest drives, with most of the field scoring more than 200MB/sec, although the 16ms random access time and 87.4MB/sec average sequential read speed were respectable enough.
Performance is coupled with a high price of £65 exc VAT (and a high cost per gigabyte of 9.3p), which makes this Barracuda an unpalatable proposition. Other 750GB drives - such as the Samsung SpinPoint F1 - offer better performance and value, and are far worthier choices.
