Single Client Throughput
- HD Video Play - 720p HD stream from Windows Media Player, 256kB reads
- HD Video Record - 720p HD stream, 256kB writes
- File Copy from NAS - 4GB file copy, 64kB reads
- File Copy to NAS - 64kB writes
We start off testing by setting up the Linkstation 520 with comparable solutions, Zyxel Personal Cloud is likely the closest 1:1 we have while the Asustor and Qsan are much more powerful in the CPU area. That said, Single Client testing gave the Buffalo 83 MB/s in Playback, 106 MB/s in record and 99 MB/s File Copy to and 63 MB/s from the NAS.
RAID 1 was the best scenario for the 520; we see 106 in playback followed by 101 in record. File copy operations sit at 94 MB/s to the NAS and 64 MB/s from.
Benchmarks - Sequential and Workloads
Our Sequential read/write workload is centered on 128K transfer sizes at QD32.
Sequential performance reached 110 MB/s read, and 106 MB/s write for the 520, a touch faster than the Zyxel solution.
RAID 1 showed the 520 and Zyxel nearly identical in performance, both reaching 109 MB/s read and 105 MB/s write.
Moving into workloads, the Linkstation gets a bit out its element but does offer consistent performance across the board.
RAID 1 again was better for the 520, doubling performance across every workload and once again nearly identical to the Zyxel solution.
