Hi, fairly new user to UnRaid here.

The only thing that I am remotely displeased about with it is the write speed, not really a problem but irritating. I understand the reason given that it's writing to both the destination and parity drives but I thought that having the parity drive on a separate controller would help matters. My motherboard has two controllers on board so I tried that but it made no difference. I then fished out a PCIe SATA controller and moved the parity drive to it but still it was the same.

Surely in that case it is writing to two drives via separate controllers on different buses so both should run at full speed? Since that isn't the case, why are writes so slow?

BTW, I have set my UnRaid as JBOD + Parity, is this a common configuration? My reasoning was that if a drive started to fail, I couild move it to my Windows PC and read off as much as I could using tools that I am familiar with. Any form of striping would make this impossible so it's another layer of security. Any known downsides to this?

Simon.

It's a not a bandwidth issue, but see turbo write:

Thanks.

Windows can't natively read Unraid disks.

Yup, I tested it before fully committing to UnRaid, it works pretty well.
