Seagate performance

[jkingma]

Are these numbers for a seagate ST2000VN000 good or ok?

Is the qnap clever enough to make sure a RAID10 uses the SATA3 connections for reading? and ignore the SATA2s

[jkingma]

can i swap HDD between slots without a problem?

[dolbyman]

These are 7 year old HDD models, so sequential read speeds are 50% slower than modern drives.

Why RAID10 and not RAID6, if dual parity is needed?

If you want to swap the drives around (why?) you can only do that while the NAS is off, otherwise you will cause a RAID rebuild

[jkingma]

Ofcourse they are 7 year old! they have an amazing live span. And what is modern now is not in 7 years.
The reason: the ts435 sport a SATA3 and a SATA2 controller. So here is the thing in a RAID10 It would make sense to have the read section use the SATA3 instead of the SATA2.

What are you doing wit the NAS, that you would care ? .. 1GbE would be your limit anyways.

You can see the SATA speed in the Disks overview
