I tested the TVS-682 both with and without caching - the cache drive used was a Crucial MX200.
As you can see in our RAID 0 chart, the cache didn't help much over a single Gbe connection. In fact, in some cases, we lost performance.
RAID 5 did get a very slight boost from the cache while the standard setup was able to reach a peak of 115 MB/s in playback and 110 MB/s in file copy.
RAID 6 shared similar performance, topping out at 114 MB/s in playback and 112 MB/s in file copy.
112 MB/s was the peak for our RAID 10 array while adding in the cache brought that to 122 MB/s.
Benchmarks – SMB Performance
SMB performance is tested over several test sizes including 100, 800, 1000 and 8000M with each test ran three times. The average of these three runs is recorded in the charts.
The TVS-682 performed quite well with RAID 0 at 116 MB/s while RAID 5 and 6 came in at 109 MB/s and 88 MB/s, respectively. RAID 10 wasn't quite able to match RAID 0 and landed at 89 MB/s.
Write performance, on the other hand, showed steady performance across all RAID modes including RAID 5 and 6 where I expected to see more of a performance hit.
