I want lightning fast HDs - SCSI Raid help

I am doing some database work, compiling, reading, etc. I want it to be super fast, it is far too slow on my 36.7gb raptor right now. I also do other stuff while doing this database work, such as internet browsing, maybe photoshop, hopefully gaming?

So here is my solution: 2 of these in some kind of RAID

my problems are: what controller card should I get? (i will be using this in conjunction with a new ASUS p4C800-E and a 3.2ghz extreme edition P4)

what RAID should I use for the fastest SPEED, but also reliability? would RAID 0 be best since the drives i'm getting should be incredibly reliable and failsafe so 2x chances of failure would be like 2 x 0 = 0?

thanks.

edit: what about newer 22.5k drives or newer 15k drives, worth holding out for?
 
Raid 0 is more like 2x1 so 2x chance of failure. I think RAID 0+1 or 5 maybe better. Adaptec controllers seem to be popular. What local shop here carries
 
hm.

I want to use this setup also for watching HDTV on my HDTV Wonder which is a PCI card. The HDTV signal is pretty huge, so would that saturate my PCI bus and mess up performance on my SCSI array?

Should I go for LGA775 instead?

Advice needed.
 
Read my site and you'll see the parts I ordered. Don't really think you need to run Raid 0 with SCSI, but you can if you want, the controller supports it.

Newegg is where I got them.

When you order the controller, it comes with a ribbon cable, floppy (drivers), and short manual. Make sure you get these pieces. They were missing for me, only got the manual, but I called Newegg back and they sent them.

Now, when you go to install windows, it copies files to your hard drive and then reboots. You need to press F6 and install the SCSI drivers from the floppy. Then XP will continue the install and everything will be fine.
 
It's too bad you didn't get a motherboard with PCI-X or 64 bit PCI slots. If you're looking for a good SCSI RAID card, I suggest looking for the LSI Logic MegaRAID Elite 1600; I have that card and it's wonderful. The performance, however, is much better on a faster PCI bus. Right now your two HDs could easily be limited by the 33 mhz/32 bit PCI bus.
 
look there for your info.


usualy speaking RAID 1+0 is the fastes of them all, but it requires 4 drives minimum.

RAID 0 is great but provides no data protection

so then RAID 1 woul be considered the second fastest for OLTP

followed by RAID 3 - which is great at long streaming reads

RAID 5 is a nice all around performer and most cost effective per MB

Fujitsu MAS3735 is the performance king right now

And your math is wrong
incredibly reliable and failsafe so 2x chances of failure would be like 2 x 0 = 0?

With 2 drives in a RAID 0 setup you have a 2 times greater chance of failure that a single drive, then also add in the RAID controller and possible corruption the chances are much higher than 2x.

in the 2 x 0 = 0, 0 = chance of failure. because these ARE scsi drives, the chance of failure on one drive is way closer to 0 than an IDE, so doubling that tiny chance is nearly 0 as well.

i think i will go for raid 0, and also wait for the new MAU drives coming out.

now my biggest concern is, as stated above, should i run it on the pci bus or go for LGA 775 and do pci-xpress.
 
i run that hard drive, but not in raid. you, my friend, are crazy. the singular solution is more than sufficient. btw i use the tekram DC-390U3D_U3W

if you say so 😉 Good luck
 
Maybe all you need to do is to seperate your os, & programs. Look at my sig.
I use a 36g 15k for OS: win2k & Linux + a partition for backups.

my 2nd 15k drive is used for programs & games
my 3rs 10k drive is a scratch/temp drives for all my programs

Then I use a raid 0 of 73g raptors for video editing. I didn't want to spend $600 on a 74 g scsi drive because I'd need two of them for $1200/pr.

I have the p4c800e w/ an adaptec 29160n adapter.

Its al a matter of money. You want speed, you pay for it. I got the PCI-X 64-bit 133mhz slots, and a good controller, but I am only at U160 and 10k rpm. My next upgrade will be U320 and 5-6 of the 36 or 73 gig drives mentioned in this post (the Fujitsu's) And as for failure rates ? SCSI is in a difference league than IDE, and almost all have a 5 year warranty and a much higher MTBF. Also, if you don;t use tape backup's then you are at risk anyway.

BTW, 5 10k drives will blow you away in raid0, I should know.

Well $ is not an issue. I want super fast speed, but don't need it for my whole comp. So I will have a 250GB WDSE for storage, then the 2x36.7gb 15k drives in RAID0 for my apps etc.

I think I will ghost the RAID array every week or something on my 250GB WDSE, then I should be good.

edit: also how do u like that pci-x card? I think I will go for the next generation route and get the new mobos. Any recommends on the SCSI card I should get? U320 RAID for PCI-X?
 
LSI MegaRaid 320-2x ....... This a 64bit/133mhz dual channel scsi raid card..

So what will you put your OS on ?? not the 250g wdse or the raid0 array ?
I'd put the OS on a seperat 15k drive or on a raid 5 array.

Jose
 
Thats the card I'm using, the MegaRAID 320.. I got 4 73GB Atlas 10K III on it for storage and a few smaller 18gb 15k seagate for boot.

If you backup daily, you dont need to worry about drive failure, why not get 3 or 4 drive raid 0.

I have a db here using 4 seagate 73gb 15k, its not as fast as I wanted but only got room for 5 drive and 1 is hot spare.

What he needs in addition to that Megaraid 320-2 is a 64bit PCI-X slot, and they are available now. Unfortunately, they are are hard to come by except on my Tyan Thunder K8 (assuming you also want an AGP card) And if money is no issue, 4-6 drives would be sweet in raid 0 !
