this will be for my main server needing 8 ports not realy used raid before so not rely no what i am doing with it but what i wont is 8x 2TB drive to show as one drive dont realy need them for backup as my second server will be used for backup of the main server so just needing fast speeds on the main server with some security
I'd probably go with an LSI megaraid 8 port card with 256 to 512MB of cache and a battery module. Just make sure the model you pick supports 2TB drives. As far as the RAID level goes, I'd use RAID 6. You will lose the capacity of two drives for the array, but will be able to lose any two drives to failure without having your array fail. RAID 5 is another choice and you will only lose the capacity of one drive for the array, but with that large of an array RAID 5 can sometimes struggle compared to 6.
i actually use windows 7 built-in mirroring and/or striping (depending on the machine). the disks/ssd's are connected to the onboard SATA ports and set to AHCI. works as fine as the intel onboard raid. latency's are a little higher i think. but this is just a guess, not a fact.
but if you wanna do a proper raid 5 or raid 6 i'd go for some adaptec 5805 or similar (i.e. 3ware). if you just wanna have SATA with a much simpler and therefore less costly card: i have made very good expierience with HighPoint RocketRAID cards.
if you wanna run linux on that box you're certainly best supported with 3ware and adaptec controllers or simple software raid.
I can recommend an adaptec 5805, but you would need to buy a BBU for it for security. Software RAID has some advantages (it's cheaper), but realistically if you want RAID 5/6 then a dedicated card is what you want. Onboard RAID is a awful. I ran RAID 5 with an onboard motherboard RAID controller and topped out at 5MBps.
On the dedicated RAID card I can get somewhere around 220 on the RAID 0 and 200 on the RAID 5. (2 and 3 drives respectively). If you only have 1Gbps ethernet that is more than adequate.
