Just loaded readynas 516 with these drives (ST8000AS0002)
I just wanted to let people know that the readynas 516 is working just fine so far with Seagate ST8000AS0002 8TB hard drives. I so far have populated it with 4 of them and it has had no problems. Once all 6 are done I will post back to let any one that wants to know these 8tb drives work. So far with 4 populated with 8tb drives and the other 2 are 4 tb drives its working just fine.

- Hey @rgollar. Do you have any performance stats for running these 8TBs in your server? I'm about to put 6 of these in my ReadyNAS 6 and was just hoping it could saturate the gigabit link. With just 2 disks I see speeds vary from 30-160MB/s when writing. Reads have been consistent.
- I have had no problems yet as far as speeds. If I copy a file say 2 gb its stays steady at around 108-118MB/s but when I copy a file say 8gb it usually goes down to around 96MB/s but its stays steady there. What I have found is if I have used my computer alot to download stuff that I need to reboot the computer to maintain speeds. Other then that I have been running smoothly.
- Hey @rgollar. Just had one last question for you. Do you know how long/how fast your initial sync was on these drives? I just installed 6x8tb in my ReadyNAS Pro and the sync is showing something like 6 days to complete, hovering around 16MB/s sync:

I'm ok if this is the one time cost, but even at 15MB/s, this seems low for these drives. - I only upgraded one drive at a time. I previously had it with 4tb drives in each bay. So when I updated it I swapped one out at a time and let it up date. It took about 1 1/2 to 2 days each drive. I also waited 3 days between adding each hard drive, just to make sure there wasnt any problem before I added another drive.

Thanks for the info! I'm assuming you're also with X-Raid2 dual redundancy? This will be about a week for all the drives to sync.. which seems in line with your 1.5-2 days per drive.
