What setup would best suit my needs?

post #1 of 5
Thread Starter 
Hello

I have been browsing numerous threads but cannot come to a decision as there are so many choices.
JBOD, Raid 1 - 6, ZFS, NAS, SnapRaid, Mdama... etc etc.

I have 5 x 2 TB hard drives which I need to store video media.
I do not know in detail the benefits over each of the storage setups I mentioned although Raid 6 sounded like a possible choice.

Thanks in advance.

Are you going for maximum redundancy or a balance of performance? RAID 5 provides a good balance between space, speed, and redundancy. RAID 6 is comparable but sacrifices space for added redundancy and may not be as commonly used or found on controllers.

I question the likelihood of two drives failing simultaneously and prefer to have as much storage capacity as possible. So, I suggest you use RAID 5 as it offers all the benefits of various RAID configurations to an extent that is within relative reason.

RAID5 is too long in the tooth, with the current 2-4TB drives, as the likelihood of encountering an URE duringa rrebuild is incredibly high. I dislike parity RAID and have found RAID10 to be the best solution for all my needs across multiple systems, but if you really want parity, R6 is the minimum I would use.

You mentioned you have 5 X 2tb drives. So between Raid 5,6 and 10, I would rule out Raid 6 as Raid 6 only makes sense from 6+ drives onwards. The less drives you have, the less exposed you are on drive failure.

Between Raid 5 with your 5 x2tb drives that gives you 8TB use able space, as one drive is parity.

Between Raid 10 with you 5x 2TB drives that will give you 4TB Use able, + 1 drive sitting in hot standby. Remember Raid 10 drives are added in the array pool in pairs for Mirror (1) + Stripe (0).

If your drives were each 3tb+ in size I would say Raid 10 all the way...for the reason I'd want my failed drive to be rebuilt within less than 24hours.

Raid 5 with 3tb drives possibly could take close to a day and a half to rebuild.

Remembering while your using 2TB drives, your raid rebuild should be achievable under 24 hours if your using a good raid controlller.

Speede: Raid 10 reads and writes significantly higher than Raid 5.

For your usage requirements.... consider whether space is more important than speed or not. Raid 5 or 10.... is what I recommend to choose between.

Just to repeat : Raid 6 is only beneficial over Raid 5 when your going above 5 disks in the storage pool, and Raid 6 does require a very good raid card as it can be more taxing on the CPU than Raid 5. Anyone with 6 drives or more... I would not recommended Raid 5.

What's my personal choice? For me it's Raid 10.

Raid 5 or 10 for your small requirement...you will be happy.

That's my 2cents from working in storage industry.
