Four 3 TB Hard Drives, Tested And Reviewed

Features

Hard drives able to hold 3 TB of data need to be considered carefully because they might not always work as expected. This round-up of four high-capacity disks compares products from Hitachi, Seagate, and Western Digital, then covers their caveats.

Benchmark Results: 4 KB Random Reads/Writes And Streaming Reads/Writes

In random reading and writing of 4 KB data blocks, the 7200 RPM drives don’t beat their power-optimized competitors, but rather fall slightly behind those "slower" devices.

Thanks to their faster spindle speeds, the Seagate Barracuda XT and Hitachi Deskstar 7K3000 have lower access times, allowing them to come out in front in the streaming Iometer benchmark.
