Storage Solution - RAID card?

Last response: in Storage

I'm converting one of my boxes to a storage server for local use.
Any advice for a good PCI RAID controller or where to read up on some good comparisons?
This will be multi user access, up to ~10 at a time, with somewhat large amounts of data going to and from. For drives I'll be using 6x WD RE 4TB in RAID 10, (though I'm debating RAID 6, Suggestions for this are also welcome)

Thanks in advance!

If you use RAID10, may as well use software RAID to save money! there is not a whole lot of load with RAID10 just one or TWO SATA6 PCIe card then you are done...
But if you want RAID6 then use PCIe HW card like:
This can get your about 600MB/s

Or you can use a low cost HW raid driver-less - RAID5 can be use with ANY SATA host port
This can get you about 250MB/s

Since your data being access via network app 100MB/s, therefore both of solution will work

ONE thing that most pp fail, there is when a HDD failed, out of panic they shut it down and replace the HDD... That is a BAD practice.

RAID1/10/3/5/9 are hot swap RAID... it behaves much better when replace BAD HDD hot (while RAID is running).

Are you sure you meant a PCI raid card?
If so don't bother building. PCI might be decent for a basic home user but 10 people with large files will be a big bottleneck with pci's 100MB/s transfer speeds (which is shared by everything on the pci bus)
Consifdering a modern harddrive can hit 200MB/s and SSD's more than twice as fast; PCI is not the way to go forward.

I doubt there is RAID6 PCI controller
