Mixing Seagate hard drives

Post by hyvokar » Thu Jul 05, 2018 8:41 pm

Hi!

Some time ago I bought QNAP TS-853A-4G and housed it with 4x 6TB seagate drives, ST6000VN0041. I configured them in raid 5.
Now I need to increase the storage but the ST6000VN0041 line has been discontinued and has been replaced with with ST6000VN0033 .
Can I add ST6000VN0033 drives to existing array?
TS-853A 4GB 5x Seagate IronWolf 6TB + 2x SSD 860 QVO 1TB
TS-1673U-RP 24GB 12x Seagate IronWolf Pro 12TB + 2x SSD 860 EVO M.2 2TB

Check the compat list, quicker than asking here.

Hi,

yes, they both are on a compatibility list, but my question was can I mix different type of disks in the same array.

Yes, there are no problems with mixing compatible disks (even from different manufacturers) in a RAID. The only disadvantage being if performance is vastly different between the disks, the RAID will be slowed down by the slowest member disk.

I would recommend a migration to RAID 6 sometime around 5 or 6 disks.
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!

A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.

All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!

I would think of going with the 8TB.

Yes you will loose 2tb on each now but think ahead.

Replace each broken 6 with an 8 and before 2 long u have 6x8

It probably comes down to a budget thing but think about it.....
Qnap TS-1277 1700 (48gb RAM) 6x8TB WD White, 2x8TB WD Red - Raid5, 2x M.2 Crucial 1TB (Raid 1 VM),
2x SSD 860 EVO 500gb (Raid1 QTS), 2x SSD 860 EVO 250GB (Cache), 2x M.2 PCIe 970 500gb NVME (Raid1 Plex and Emby server)
Qnap TVS-1282 i7 (32GB RAM) 8x10TB WD White - Raid 6, 2x M.2 Crucial 500gb (Raid1 VM),
2x SSD EVO 500gb (Raid1 QTS), 2x SSD EVO 250gb (Raid1 Cache), 2x M.2 PCIe Intel 512GB NVME (Raid1-Servers)
Synology -1817+ - 2x10,2x8,2x6 (Ironwolf) 2x6 (WD Red) - SHR
Drobo 5n - 3x2TB WD Green, 2x3TB WD Red - Drobo Raid
Buffalo LinkStation - 2x2TB WD
ProBox 8 Bay USB3 - 8x4TB Seagate - JBOD
All software is updated as soon as it's available.
I give my opinion from my experience i.e. I have (or had) that piece of equipment/software and used it! :roll:
