40 TB NAS storage recommendations...

Thanks all for your suggestions and recommendations..
I ended up buying the Synology Diskstation DS2015 with 8 x 8TB hard drives.
Now waiting for the shipment..:) -
@Francesco-Provino This data needs to be onsite due to the size of files and nature of usage, so cloud hosting is not an option.

What disks did you decide to use? 8TB are very large disks.

I know that this is a little late, but we use Buffalo TeraStations here. The 7000 series have has dual power supplies. It comes in 24TB, 48TB, 96TB, and 120TB flavors. That's about the extent of my knowledge about them though.While we do not use the 7000 series we have had good luck, and only one disk failure (knocks on wood) with our three (3) TerraStation 5400's. Support wasn't a terrible experience either.
note: when I say "we" I do not mean osTicket. I actually mean the company that I work for [which is a medium sized non-profit].

@StrongBad I bought WD WD80EFZX 8TB Red 3.5” IntelliPower SATA3 NAS Hard Drive
In fact I didn't worry much about the disk spec. as this data is used rarely for reference purpose and I do have a copy of this data offsite. -
@ntozier Thanks!
I am based in Australia and probably that is why I never came across with this product when searching online. -

@Reid-Cooper RAID 5 (SAM - please excuse me :))

Uh oh, you'd better start running now. I'll try to distract him.

You are kidding, I hope. With 40TB on WD Red (consumer, URE 10^14, 5400 RPM) the chances of RAID 5 saving your bacon approach zero. Even at 4TB RAID 5 is totally useless in that scenario. At ~4TB the chances of recovering a failed disk from URE risk alone is 50%. At 10x the size, 40TB has essentially no chance of recovery, and that is only from URE risk. Add in the risk that one of the seven remaining drives will fail during the long, slow resilvering process and the risk gets higher yet.
In ALL seriousness, RAID 0 is actually likely better at this size. You are passed the inflection point I believe where RAID 0 actually is less likely to lose data than RAID 5!!

Many year old article on why RAID 0 gets safer than RAID 5 at scale.

It's a big deal knowing that someone like ioSafe will respond to a query here in like hours if not minutes.
Oops.....

LOL. Better late than never.

@scottalanmiller So what would you suggest in my case? RAID 10?

Or RAID 6, but 40 TB might be close on 40 TB. I don't recall what the line is for moving to RAID 7 is.

RAID 7 isn't available on any units like that. So not an option for him. He'd need a SAM-SD to look into that.

RAID 6 can be okay at that size still. Pretty big, but not overly big.

I was wondering... Wonder also if a SAM-SD would cost less ...

Pretty much once you are into rack mount gear, SAM-SD costs less than "store bought." Plus you get more choices, features, flexibility and options like RAID 7.
