Home server advice

[Davide]

What should I run for my new home server RAID 5 or 6?

How much of a performance differences is there and How much more secure is my data?

One other Question should I go with

Western Digital Red 3TB

OR

Seagate Barracuda 4TB

I know The reds are built for home severs/nas but the seagates have a lower cost per GB and a higher RPM.

Performance difference = pretty much nothing. Data security? That's up to how you do things.

I'd personally go with 2TB drives; from what I've seen 3 and 4TB drives tend to fail more often and also not all systems can read 3 and 4 TB drives because of the way things used to be done.

You'll need an extra drive for RAID 6 for the same amount of usable storage (minimum 3 vs 4 drives). RAID 6 allows 2 drives failures. This is going to be pretty rare and only really starts getting important with larger arrays (7-8 drives or more). RAID 6 will also allow the array to be built back up quicker if a drive fails. I'm pretty sure there is no read/write difference between the two. If using 5-6 drives or less I'd probably just go with RAID 5.

I like WD drives & the Reds are built for RAID so I'd pick them.

Get 3TB Reds in a RAID 5 solution

This post pretty much says it all.

For reference, I have 4xWD red's in raid 6 off of an LSI 9260-4i and I get 185MB/s reads and 200MB/s writes. That being said I would advise raid 5 because you don't need a controller and you get n-1 drives worth of usable capacity instead of n-2
