Please advise on 25TB storage requirement

[bhvn]

Hi,

I have a requirement of around 25TB space with redundancy so planning to buy a RAID enclosure.

- ~25TB usable space
- No need for NAS capability
- RAID 5 (for redundancy & speed is not an important issue)
- atleast 5 bays
- USB 3 or 3.1 is fine
- planning for 8TB x 5 drives OR 6TB x 5 (6TBx5 might be tight as usable would be around 22-23TB. I might go with 6TB as they are cheaper if I buy 8-bay enclosure)

Could anyone please advise decent RAID5 enclosure with HDDs? Less the price the better.

Thanks!!

We are in Professional photography and video business. ATM we have lot of individual disks and making 2 copies of each video/photo (these are very HQ, big size files and we must maintain 2 sets of copies). It's very difficult to manage data on multiple drives. So instead of 2 sets of copy/backup we thought of RAID solution with huge volume so its easy to maintain data/integrity. Thanks!

RAID5 isn't a good idea for this. The odds of loosing the entire array during a rebuild is too high.

Look at RAID6 or some other dual parity option.

More complete information on how it's going to be used would help with providing suggestions.

Could you please throw more light on why i should NOT use RAID-5? It has one 1 disk redundancy with distributed parity. If one drive goes down and I replace it immediately (before 2nd one goes down) then I should be good, right? Also we are using smart disk monitoring tools to keep a track of drives.

We have few machines but We want to restrict the storage only to 1 machine. Maybe we will use "Windows share" temporarily when needed. Thats why not preferring NAS option. BTW what would be the cost difference between "NAS storage" vs "RAID enclosure connected to a PC"?

Thanks!

You never said how much you want to spend

Because I have no idea about it.
I would like to hear from experts here about few models/solutions with their rough prices then I can perhaps make a decision.

Thank you bledd & everyone for your replies.

Any suggestions on just RAID enclosures please ( without NAS option) as I prefer to connect it directly to a PC.
