Hello,
First the story, why I did what.
I have an Qnap 673. Which is perfect for fileserving, and 2 VM's.
Yet it lacked power while using it as a Plex server at home.
So did build an AMD 3700X pc, and added 4x 1 TB 2.5" WD red.
And used Windows 10 Storage Spaces for building a raid system.
Now the problem
Then I did find out that the performance of the Storage Spaces is lower then the Raid 6 I had used in the Qnap.
The Qnap had the same disks in them, and The read performance was high. Write was a bit slower.
I think that the diskspeed was around 100MB per disk. In a Raid 6 it had a readspeed of over 300MB. Write was around 100MB
Though on the AMDcomputer the readspeed is 200MB and the write speed 25-35 MB for small files and 40-70MB for large files.
I considered that low. And I bought an LSI 9361-8i from Ebay. Build it in, and had about the same performance.
Wether I used raid 10 or 6, did not matter.
Does this mean that the Linux version on the Qnap is so much faster then the Windows version?
I had tried running Freenas and other Linux versions on that mainboard, but as it has an onboard 10Gb networkcard, which appeared to be the bottleneck. It was simply not recognized. And of and on other hardware was not recognized.
Back to the issue.
Why is the LSI having the same performance? It is even a tad bit slower than Storage Spaces?
I did read on several places that adding a CacheVault would solve the issue, as the availability of a battery, tells the Cache on the board that it can work fullspeed.
But I cannot imagine a battery speeding up a disk. Can somebody give some insight?
I have been thinking about the CacheCade. But I do not think that it will add anything. Adding SSD's in the Qnap for cache did not help there either, as I am using to few files to have advantage of cache. Maybe I am mistaken.
Some advice would help me.
Thanks ahead,
RobB
