ATTO Disk Benchmark

The ATTO disk benchmark tests the drives read and write speeds using gradually larger size files. For these tests, the ATTO program was set to run from its smallest to largest value (.5KB to 8192KB) and the total length was set to 256MB. The test program then spits out an extrapolated performance figure in megabytes per second.

Once again the Black Edition 4TB represents a major improvement over previous generations. For the most part, it is everything you would want to see in a new high performance HDD meant for the consumer marketplace. However, it does appear that the firmware of the Black has been tuned with drastically divergent priorities when compared against its simbling, the RE 4TB.

The most noticeable difference is not in the read or write curves per say, but in the whisper quite operational acoustics. Unfortunately this noise reduction appears to come at the expense of a moderate performance impact. Most consumers will agree that this is a trade-off well worth making as previous Black generations were anything but quiet.
