Seagate Backup Plus 1 TB External HDD Review

CrystalDiskMark

CrystalDiskMark is a hard disk drive benchmarking program that measures sequential and random write and read speeds. We compared the results in sequential read and write, and in random read and write using 512 kiB blocks. We configured it for five repetitions of each test of 1 GB of random data.

The graph below shows the sequential read speed for each drive, in MB/s.

In sequential read, the Seagate Backup Plus was 27% faster than the Toshiba Canvio 3.0. It was 26% faster than the Western Digital WD10EARS, and reached the same performance of the Seagate ST1000LM024, that is the same hard drive used internally by the Seagate Backup Plus 1 TB.

The next graph shows the write speed of sequential data, in MB/s.

In sequential write tests, the Seagate Backup Plus was also 27% faster than the Toshiba Canvio 3.0, and between 18% faster than the Western Digital WD10EARS. It was 6% faster than the Seagate ST1000LM024, the same hard drive used internally by the Seagate Backup Plus 1 TB.

The following graph presents the random read speed using 512 kiB blocks, in MB/s.

In the random read test using 512 kiB blocks, the Seagate Backup Plus 1 TB was 14% faster than the Toshiba Canvio 3.0 1 TB. It was 21% faster than the Western Digital WSD10EARS internal drive, and performed as well as the Seagate ST1000LM024 (which is the same drive used internally by the Backup Plus).

The following graph presents the random write speed using 512 kiB blocks, in MB/s.

In the random write test using 512 kiB blocks, the Seagate Backup Plus 1 TB, the Toshiba Canvio 3.0 1 TB, and the Seagate ST1000LM024 achieved the same performance level. The Western Digital WSD10EARS internal drive was 39% faster than the reviewed hard drive.
