Asustor Drivestor 4 (AS1104T) 4-bay NAS Review

The PCMark 10 Data Drive Benchmark has been designed to test drives that are used for storing files rather than applications. You can also use this test with NAS drives, USB sticks, memory cards, and other external storage devices.

The Data Drive Benchmark uses 3 traces, running 3 passes with each trace.

Trace 1. Copying 339 JPEG files, 2.37 GB in total, in to the target drive (write test).
Trace 2. Making a copy of the JPEG files (read-write test).
Trace 3. Copying the JPEG files to another drive (read test)

Here we show the total bandwidth performance for each of the individual traces.


The Drivestor 4 handles PCMark's 10 Data Drive Benchmark very well. In terms of overall bandwidth, there's not much to choose between any of the arrays. The fastest speed of 54.97MB/s came from the RAID 0 array and the slowest 50.23MB/s came from the RAID 5 array. The same can be said for the individual cps1, 2 and 3 test traces.
