RN214, query on a 2nd vertical expansion
Hello Forum Simply query, just checking. Can I carry out a “vertical expansion” more than once? I have a RN214 ( 6.10.3, X-RAID) which already went from 4x 4TB to 4x8TB, and I am just about t...
Hopefully, you've not unboxed the 12TB drives, because your plan is very inefficient cost wise. Updating all 4 8TB to 12TB only adds 12TB of storage at the price of 4 x 12TB drives. For less money (and fewer re-syncs), you can swap out two for 24TB drives and get a 16TB increase with the option of later swapping another, and then later another, for yet another 24TB for an additional 16TB from each. I believe 24TB to be the best size-to-cost ratio available today. On Amazon, a 24TB Ironwolf Pro is the same price as a 20TB.
The only reasons to be doing what you are is if you suspect all the 8TB drives are in need of replacement or if you are using FlexRAID (which requires all drives be of equal size). But if you are using FlexRAID, the incremental syncs StephenB listed are not what you will see.

I agree that would be more cost-effective to get fewer larger drives.
Though I believe berillio is in the UK, not the US. Looking at amazon.co.uk, the most cost effective combination I see is 3x16TB+8TB. That adds 16 TB at ~£49/TB gained (£784 total cost).
My suggestion above would give him a much smaller storage gain, but would also give him enough capacity in the PC to back up his volume going forward. That could be modified to go with 2x16TB+2x8TB, with a 16TB and one or two 8 TB drives in the PC for backup. Cost would be the same (assuming no exchange fee on the disks), and it would give him more space in the volume than my original suggestion.

FWIW, I am seeing 20 TB at about $400, and 24 TB at about $480. Cost per TB is the same (perhaps that is what you meant)?

When I looked, both were $399US. Amazon prices can change quickly and I now see that as well. But moot since the OP is in the UK.
But looking at the cost per TB, including cost for future expansion, is still a good idea.
Hello Stephen B, TY for your support, Hello Sandshark, Ty for the suggestion.
Too late for that, this afternoon I received the last 2x 12TB drives ( I could return them if I wanted, even if unpacked, see further down). They were £237 each, the only 20TB NAS drive I can see on the same “shop” is the IronWolf Pro @£360, but no 24TB (no WD 24TB but a 22TB Red Pro@£511, and a 18 Red Pro @£365. I searched another shop and they were even more expensive, so, as StephenB hinted, price on this part of the pond may be very different. TBH I am NOT that comfortable with the larger size which Sandshark is suggesting, but that may simply be because I am not used to them.
I didn’t say in the previous posts that the 8GBs which will come out (which are in perfectly good condtion, no errors reported, 19990,19970,19841 and 14845 hours of use), will be fitted to the Zimablade #2 which is in transit. I also have Zimablade #1 which is fitted with 2x 4TBs which came out of other RNs in the past, 2 or 3 more 4TB have been filled with data and are in “cold storage”, I can easily plug them in the Zimablade and read the data off them.
I should eventually end up with 16TB on the Zima plus extra 12TB in the expanded 214.
The initial plan was to get another Zimablade (#2), so I bought 2x 8TB (IronWolf DB002 running @5400rpm); on arrival one tested fine, but the other wasn’t even read by the BIOS, so I filed the return as DoA (Dead On Arrival), but then even before they replied to me, I thought of expanding the NAS contacted the shop and returned both of them.
