Mini XL+ quick sanity check: 8X 4TB to 14 TB disks

[1Chris]

About 99% sure it wouldn't be a problem, But just in case:

I have a (2 years old) mini XL+ , 32 GB ram, 8 4tb disks. Use case is personal-use, mostly longterm storage for a few people with Emby running for video streaming, Windows file history backup and not much else. Been great so far, But used disk space is slowly creeping up so swapping in larger disks is probably going to happen. Any problems with this setup if I just went all-out and jumped all the way up to 14tb disks? (From the approved drive list) Given the cost, more ram wouldn't be a huge deal if it was needed but buying them and finding out it just can't work reasonably well would be an unpleasant surprise.

Good to go, Or dumb idea?

jumped all the way up to 14tb disks?

Like this?

Code:

<ATA WDC WD140EDFZ-11 0A81>        at scbus3 target 0 lun 0 (pass3,da2)
<ATA WDC WD140EDFZ-11 0A81>        at scbus3 target 1 lun 0 (pass4,da3)
<ATA WDC WD140EDFZ-11 0A81>        at scbus3 target 2 lun 0 (pass5,da4)
<ATA WDC WD140EDFZ-11 0A81>        at scbus3 target 3 lun 0 (pass6,da5)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 0 lun 0 (pass7,da6)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 1 lun 0 (pass8,da7)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 2 lun 0 (pass9,da8)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 3 lun 0 (pass10,da9)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 4 lun 0 (pass11,da10)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 5 lun 0 (pass12,da11)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 6 lun 0 (pass13,da12)
<ATA WDC WD140EDFZ-11 0A81>        at scbus4 target 7 lun 0 (pass14,da13)

Which is a dozen of them in a Supermicro 2U chassis.

(From the approved drive list)

That's the important bit. As someone else recently discovered, accidentally putting in 7200RPM drives results in a very hot-running unit. You are advised to at least glance at the following article.

Although I guess there are also accusations that some of the WD drives are actually stealth 7200RPM drives that are labelled 5900RPM.

Given the cost, more ram wouldn't be a huge deal if it was needed but buying them and finding out it just can't work reasonably well would be an unpleasant surprise.

As for the RAM, performance may be better with more RAM, but it certainly isn't problematic.

Well that was nice and simple, Thanks!

I did run into that thread about the hot drives - Really highlighted that sticking to the approved drive list is a good idea even if cost per disk runs a bit higher. The size of the headache getting disks I couldn't use isn't worth it. I'll definitely give it a re-read in case I missed anything.
