Raid help – onboard controller or Raid card. . .

[Bob Zelin]

2 Hitachi or Seagate SATA drives with an E4P will give you about 128mb/sec.
So 4 drives (put them in a nice external enclosure, like a Firmtek 4 bay, or Sonnet Fusion 500) will dramatically increase that performance.

maybe try the nvidia raid, if you haven’t already. i switched to it and got much better results.

Maybe I have been asleep, but NVidia makes graphics cards, not RAID controllers. What model NVidia raid controller do you have ?

the motherboard for that model is a nivida nforce4 motherboard chipset. the newest drivers for the raid are
on the nividia website.

Hi Jamination,
I am also looking at that motherboard for a system. Do you mind sharing what drives you are using and what kind of performance are you getting with NVIDIA RAID O?
Thanks,
Gary

i have 3 wd320 drives connected with a read/write speed of 163.
we have been using it for about 2 months with no problems. when i had
them connected to the other controller i had speeds less than 80.

Thanks Phil,
Those are some pretty amazing numbers or onboard RAID. Did you ever try it with all four SATA channels?
Thanks again,
Gary

[Phil Harbath]

no i hadn’t tried yet. some time in the next couple months i will add a drive. i have another decklink computer with 4 and an adaptec card that gets
around a speed of 200, i am hoping i get something around there.

Vince,

I’ve been using a Silcon Image 3124-2 Multiport host board with two outboard boxes (inside a Silcon Image 3726 chip) with 4 WD SATA II 250G in each, read speeds are about 214-220 with write speeds averaging about the same. This is a fairly inexpensive way of moving to an outboard raid system without having to drop some big bucks.
