I have a Qnap ts-251A which I have been using for a few years now.
However, the most I have been able to get out of it in terms of transfer speeds when doing a backup (using Macrium Reflect) is about 110 Mb/s. This via a USB quick access cable. I've tried two 1gb ethernet connections with link aggregation, as well as separately trying to connect using a QNA-UC5G1T (which turned out to be incompatible with my NAS).
The problem is a full backup of my machine now takes about 2 hours - which I would really like to reduce. Backup drives are 2 4TB HDDs.
I'm wondering if I went to a 10GB solution (another NAS model), but stayed with the HHDs (ie didn't buy SSDs) then realistically what would a realistic transfer speed for my backups be?
(My PC already has a 10 GB ethernet port).
Thanks

Re: realistic expections
Quick access port is just a virtual 1GbE adapter .. so no wonder.
Depending on the hard-drive moidels used and the RAID level (1,0,SJBOD,(pooled)single), you should get more than 1GbE speeds on sequential transfers on a different model(supporting 2.5-10GbE) .. yes

Thanks, I figured I would get greater speeds - but just how much greater is my question.

Re: realistic expections
Hard-drive models and RAID level were still not disclosed

Re: realistic expections
It would likely be configured as RAID 5; I'm currently using RAID 0 with two drives - but would likely move to RAID 5 with 4 drives in an upgraded machine.
The drives are WD Black 4TB (I don't have the exact model numbers)

Re: realistic expections
WD black are not NAS drives ... WD RED (Plus, Pro) would be
4TB WD Red Plus have a sequential speed of around 140MB\s .. I'd say in a RAID5 you'd get 200-250MB\s of sequential speeds

Re: realistic expections
How are you going to manage raid5 with a 2 disk bay NAS?

Re: realistic expections
I guessed that would go with the "updated other nas model" capable of 10GbE, mentioned in the firts post
