scsi raid

[fredaliasjoe]

I would like to use scsi raid, but i'm concerned that most motherboards only have a 33mhz 32bit connection to the scsi card. Doesn't this limit the throughput to 132mb/s or even as little as 80mb/s (including overhead), and wouldn't one scsi raid drive easily fill that?

Yes many SCSI RAID adapters do require the 64-bit/66MHz PCI slot for optimum performance. One will have to be willing to shell out for a server-level mobo as that is the only place they are found as yet.

it really depends as stated at www.2cpu.com(upaboveit wrote the scsi raid faq there and gave this answer to me when i was looking into scsi raid on my rig i have yet to add this to my rig as i'm still saving lol) 2 scsi hdd's in raid zero wont max out a regular mobo bus and 4 would only max out the bus when at max str's ie if you are transfering huge files all day long then yes obvously you want a bigger bus (server board) but if all your transfering are small (less than 1 gig files or ocassional large files)then you should be fine

if you are looking at two drives raided a 32 32 bus should be fine
4 drives raided you might look into 64 32 buses

and anything over definately go for 64 64 buses

now before you go shooting me and all i'd still recommend if your going to spend the money on scsi raid get more headroom than you need especially if you are considering adding on to it later but on a gaming rig ?then a standard bus should be fine😉

If your using it for gaming, it's not worth it. I have a server board and I even have a pair of fibre scsi cards. But that machine is use for video editing and second counterstrike machine. my game machine is still a p3 1ghz cusl2 with ide drives.

SCSI 64bit mobo, starting price 400
SCSI RAID starting price ~250
18GB SCSI Drive ~200
36GB ~ 300
76GB ~ 540

Have you look at serial ata ? You can get a 12 channel card and use cheaper ide drives.
