Hi all, I didn't see this posted anywhere, so I thought I'd post it.

 

I've just been migrating away from QNAP due to the cost of their hardware when you need a decent CPU / docker / VM etc.  I had a QNAP 669-L and a UX-500p cabinet.  After copying all my data off, I thought I'd just plug it in to my Unraid box to see if it saw it and after a bit of disbelief, it does!  All the disks show up individually and are able to be assigned to the RAID etc.  The screen is stuck on 'system booting' which doesn't seem to affect performance obviously, but that's about the only glitch I can see.

 

QNAP are moving away from these USB 3 cabinets I think, so there may be some coming cheap at some point.

 

In this kind of setup, I'd say it would be good to have a second array option - rather than just a single array so that parity doesn't have to go across the whole lot (might be kinda slow doing a parity check)?  On performance though, I actually found this cabinet faster than the on board drives on my 669L. I suspect just because the UX-500P had newer 8TB drives in it, whereas the internal ones were 4TB.

 

Anyway, thought I'd just post this here in case it helps someone one day.

Does SMART info. can read ?

Does Up/Dwon speed be ~300MB/s ? And what is the form (string) of disk identify.

 

Thanks

I've just put some of the disks in it, into my main machine via a Dell H310 Card.  I was going to wait until the party was done before playing around with it again, however being USB I can probably do it.  Will let you know - I think I did see smart info but need to double check.

 

I had a friend whom got an Orico external USB device and that did not work, so I was surprised somewhat when this one did.

Thanks, just interest to know more about QNAP USB DAS with Unraid.

I've just plugged it in again (live hot plug while system running with a set of different disks).  I can see all the smart info, temperatures and everything.  It looks EXACTLY like any other disk to me.  I'll try a speed test too - but given Unraid is really only good for gigabit network, it's not going to suffer that kind of speed.

 

I don't want to actually put a disk in my array for obvious reasons, but I'm just connecting it through the unassigned devices plugin.

Suppose sdm - sdq ( 5 bay ) was that, seems good.

dd if=/dev/zero of=test1.img bs=1G count=10 oflag=dsync

10+0 records in

10+0 records out

10737418240 bytes (11 GB, 10 GiB) copied, 67.169 s, 160 MB/s

 

Even the HDD LED activity works.

That's raw disk, no raid array or anything - so it's faster than a 1G connection anyway.

It doesn't work with the disk speed container though - I expect that just how the container is written, probably doesn't work with USB drives.  Yes drives sdm to sdq are the external disks.

Also confirmed, auto power down of drives works.
