Stripe 4 HDD drive to RAID 0

[sentosa]

Hello ,

I have a Sil 0680 Ultra-133 Medely ATA RAID COntroller
Im planning to stripe 4 hdd drive to RAID 0 . 2 hdd on primary and 2 hdd on secondary .

Rite Now Im using 2 hdd drive using RAID 0 .
Here's my question .
1.If using 4 hdd drive , do I Get 4 times speed faster than a single drive .
2. Are Sil 0680 Ultra-133 Medely ATA RAID COntroller , a good raid controller ?
3. if not good raid controller , can any one suggest a good raid controller .

I will be very happy and thanksfull if some one can give me info .


My PC :
P4 2.4 GHz
Asus p4s8x-x
512 RAM

1. No, more like 2-3 times, up to the maximum for your PCI-bus.
2. No idea, never saw a review of them.
3. 3ware Escalade 7506.

Actually , What is the max speed of the PCI Bus ?
Thank U

133 MB/s unless you overclock it or are using a 64 bit and/or 66 MHz bus.

Depending on your PCI bus, theoretically
<pre>Standard PCI2.0
32bit*33MHz=132MB/s
64/66PCI bus
32bit*66MHz=264MB/s
64bit*66MHz=528MB/s
PCI-X
64bit*133MHz=1064MB/s
PCI-X 2.0
64bit*266MHz=2128MB/s
64bit*533MHz=4264MB/s
3GIO
2.5Gb/s/direction=250MB/s/lane

Well, actually I just read an article in Maximum PC, about RAID setups. Here is the results of the tests. The configuration was with a Promise FastTrax TX4000 ATA PCI RAID controller on an Intel 865GBF motherboard. The hard drives were Maxtor 250 GB.

Read Performance:
1 drive = 47 MB
2 drives = 95 MB
3 drives = 113 MB
4 drives = 107 MB

As you can see, the 4 hard drive setup was actually slower than the 3 drive setup. It seems to me, that the 4 drive setup may be faster, if given more headroom. The PCI bus can only send data at 133 MB, so if that was more, there may be an advantage to a 4 drive setup. Hope that helps.

What do you use your computer for? Using 4 hard drives is gonna to be very bad for latencies.

The only advantages to a 4 drive setup is writing large files. Ex. video editing. A 2 drive setup will suffice for most users. I am going to be setting up a RAID 0 with 2 160 GB Western Digital SATA for video editing.

Im going to use for video editing ... likely reading and writing at the same time ..
