Asustor Lockerstor 4 (AS6604T) NAS Review - NAS Storage Performance Benchmarks

File copy performance

We'll also look with a file-explorer-copy, and some storage utilities to see what performance is like. Basically, we make a network share and measure the storage unit. It is the most simple test but for any centralized network-based storage probably the most used copy feature, making it a very important one. The most basic and simple test anyone can perform. We copy back and forth a 110 GB MKV file. 

copy from NAS - performance / 2.5 Gigabit 

Above you can observe copying a file from the NAS towards your local storage. The configuration was averaging out at 279 MB/sec. But now let's startup the write performance towards the NAS again:

Atto Disk Benchmark

One of the more common tools available to measure storage performance is ATTO. It is very reliable and produces accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a sequence of 4 KB files up-to 1 MB files. This gives us a pretty good overview of overall performance with small and large files in a queue.

We've seen this in the past with RAID configurations as well, write performance on these NAS units have a hard time remaining close to that 280 MB/sec marker, and remember we're utilizing the NVMe M.2 unit here. This likely is related to the SoC from Intel.
