gonna build a rig, can i raid 0 4 rators? or only 2?

[Esquire]

i do video, would i need a pci sata raid card with 2 or 4 ports?

thanks

 

[Lonyo]

You need 4 ports, since one port can only do 1 device.

Check manufacturers specs to check they will do RAID-0 with 4 drives. 2 ports will only do 2 drives though, because it's one device per channel.

 

[Nebor]

WOw... raid 0 with 4 raptors... Post your transfer rates.... Also, what stripe size do you plan on using?

 

[UlricT]

you could do that (get a PCI card).... but its almost a guarantee you are gonna be losing data sometime in the next 6-8 months. Also, you might be limited by the PCi bus if you go 32Bit. Get a Xeon mobo with 64Bit PCi slots, and you should be good to go

 

[Esquire]

ok, you guys are fast.....

so unlike ide only 1 drive per channel...

any 4 port pci sata raid cards around?

so 64 bit pci slots

what would you recommend as stripe size?

 

[digitalsm]

3ware
Promise

4 Raptors in raid 0 would be awsome on that 32bit promise card with a 256mb cache module! With such a setup, if one Raptor bites the dust, you will lose all data on all drives. So you would be best off to pick up an ata100 160gb drive to ghost the array with. I'm sure someone on here could explain how.

I would like to know this information

could you do two separate raid 0 setups or two drives each, which in turn are hooked up via raid 1?

. Raptor
. RAID 0 <
. / Raptor
RAID 1 <
. \ Raptor
. RAID 0 <
. Raptor

that would give him the speed of raptor raid 0 with the reliability of raid 1?
(i apologize, i really just wanted to draw the picture).

Why do Raid 0+1? Raid 1 is mirroring. In RAID 0+1 the two RAID 0 arrays are mirriored.

Depending on his budget Id suggest a 5 drive RAID 5 array with a 3ware 8 port SATA controller. Or RAID 0 with 4 drives and a backup drive to ghost the array.

yeah, you have the idea but it was a hypothetical thing. like, if you are going to buy 4 raptors anyway, why not ___________?

coz you will only get the speed and space of 2 raptors, as the other two will be saving the same info, and not adding to the speed.

How would you ghost the 4-drive array? Im not familiar with this.

just like ghosting a singe drive, windows will recognise the array as single drive.

yes, 4 drives in RAID0 with 1 IDE for backup is good

or RAID 5 with 5 drives, but if you want RAID 5 youre gonna be buying one of those expensive hardware RAID cards, not the cheap $50 ones

i thingk 4 drives in RAID 0 w/ single 160g to backup is optimal.

BTW, do you really have the cash for this kinda rig? or is this hypothetical. personal or bussiness?


Edit: esquire, the link in your sig has an extra "https"

 

[Lonyo]

I'd say go for some backup, maybe not mirroring the RAID, but a general backup of important files, just in case something does go horribly wrong (4 times the chance of failure than normal)

 

[Boonesmi]

i would buy one more (5 raptors) and run them in raid5... it will be that way if 1 harddrive fails the array can rebuild itself without loss of data, and you still get tons of speed

** edit to add: you dont actually need 5 drives to run in raid5 (anything 3 drives or higher can run raid5) but you get more performance with each additional drive... and the total capacity of the array will be the sum of the drives minus one (so 5x36gb drives will give you 4x36gb total capacity)

 

[sniperruff]

why not go full flag and build a SCSI server?

 

[Nebor]

Don't forget the advantage of RAID0 w/ 4 raptors is that you get 4x 36gb of HD space....

 

[Esquire]

thanks for the heads up on my sig

personal/buisness

i'm working in after effects & photoshop & premiere

ok, so which raid adapter will let me get a 5th ide hd for ghosting?

i can get 4 of these bad boys for 497 - 40 rebate so not to bad

 

[Nebor]

Well, you could just put your last IDE drive on your motherboard.... and ghost onto that.

 

[Esquire]

would that hit performance? ide ghost

 

[Schadenfroh]

dang... i need to get a job

 

[AgaBoogaBoo]

I would do a Raid 5 setup if I were you. That will still give you awesome speed and reliability if you can get a nice Raid 5 card.

 

[Esquire]

whats the price on raid 5 cards?

 

[Boonesmi]

i really like 3ware raid cards (they are hardware based raid cards so they cost more, but they are faster and dont require your cpu to do the work)

its about $300 for a 3ware card that supports 4 drives (supports many types of raid including 1, 0, 10, 5)
the cost goes up if you want a card that supports 8 drives, or 12 drives
