Mixing Seagate hard drives

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.

Thank you for your reply, I'll go ahead and order more disks :-)

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.....
