I sent the NAS with the ATA error back to Amazon, and received another QNAP TS-932PX-4G. The big question in my mind was: “Was the seeming incompatibility with the Samsung quad SSDs a hardware issue in the first NAS, or was it a design issue?” I put 4 of the Samsung 8 TB SSDs in the 2.5 inch NAS sleds — they just snap right in — and set them up as a striped (RAID 0) array. Then I started transferring files.
At first, things went swimmingly.
Not wire speed for the 10 GbE connection, but pretty swift.
But trouble reared its ugly head:
One of the SSDs has dropped out. This is the same behavior that I saw in the first NAS, the one with the hardware issue. Now I think there were two unrelated problems.
I need to find some compatible SSDs. The ones I’m using in the second NAS seem top be working well, but before I order more I should do some further testing.
I went back to NAS2 and started a 6 TB transfer:
Then I went to sleep. The next morning the information light on NAS2 was red? Had it dropped another SSD? As it turned out, no. It was just complaining that the drive was getting full. I deleted the test files.
But the SSD still showed up as full.
I emptied the recycle bin on the NAS.
It still showed up as full.
After a while, the dashboard started displaying mutually inconsistent messages:
I went to breakfast. When I came back, all was well.
My conclusions are that the SanDisk SSDs I’ve using will be alright with NAS3.
