Mixing Seagate hard drives

Postby 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?

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 TVS-1282
HD - 6x8TB Wd Red, 2x 8TB Iron Wolf - Raid 6
SSD - 2x Samsung EV0 860 250gb - Static (Raid 1) - VM
PCI-e - M.2 - 2x Samsung Evo 960 250gb - Static (Raid 1) - PMS
2x Intel 120gb - Static (Raid 0) - undecided
M.2 - 2x WD Blue 500gb - Raid 1 - cache
Back up - Synology -1817+(2x10, 4x6, 2x4) Raid SHR & Drobo 5n - 5x4tb Seagate & Buffalo LinkStation -2x 4TB Seagate = 80TB
TV client boxes - 2xShield Pro (2015 & 2017), Shield 16gb 2017, ATV4, Xbox one, Roku3, Roku4, Chromecast & Samsung Smart TV
All my software updated as soon as it's available.

I give my opinion from my experience!
