Real HBA's are SCSI based, not SATA based.

The higher end SCSI HBA intelligent I/O controller will smoke anything 3Ware makes. Those are low end stuff folks.

Cheers!
 
Actually the really high end stuff will soon be Serial Attached SCSI based, and I was listing for a single controller pci-x solution. Sheesh. SAS will be great because it will support SATA drives natively. =D
 
SAS is still a ways off and most of our clientele won't touch it until proven. SCSI disks are rock solid, you should some of the places we have them running!

Cheers!

Assuming your tring to say a rocket drive is better than that little raid array i listed you need to pay attention to a few things. First the controller is SATA. The disks have no rpms. Those disk are solid state 90GB. A raid 5 with 12 of them hits 354MBps easily and would be a little under a terrabyte, and have an real-world access time of about 80µs.
 
Well, i guess you can get a Atlas 15k or a Raptor for that now. I never bother RAIDing my system drive. Just install the os and all the drivers I need, and burn to a dvd. with a USB bootable jumpstick, if anything ever happens its back on your feet pronto. =D

 
i have almost everything raided on my server.. and its supermicro dual xeon crap..

Raid is really for redundancy.. I dont have time to waste on rebuilding system.. my server became my domain controller at home, i can log in from any of the 7 notebook/desktop and get my profiles, etc..

centralize storage + tape backup

Raid 1 - boot 73gb 10k scsi
Raid 1 - swap & virtual machines (VMWare) 10k scsi
Raid 5 - Data, 7 - 146 GB 10k scsi drives. 1 hot swap

Its not any faster but its good for storage

RAID is faster. If your OS partition isn't the bottleneck, you won't see any improvement. No need for a benchmark when logic is undeniable. 😛

But... but... that guy at the car shop told me that the "Type-R" sticker he sold me for my car would increase my HP. he swore it would...
 
Until I did the m-sys hunt (and waiting for their page to open), was going to agree with Blain. But Ribbon13 has the winner. Each drive has 100MB/s sustained R/W ops. .02 msec seek.

If your OS partition isn't the bottleneck, RAID0 would be slower because it has more overhead than a single drive. If that concept is too complex for you, time to go read some RAID articles.

If the RAID controler has its own processor (and henceforth is not mooching off the CPU's), and I have a Dual 3.3ghz Xeon machine with a Gig of RAM, I really dont see how any minute ammount of overheard would make a difference to me.

So I guess what I'm saying is, in this instance I do see the OS partition as the bottleneck here. Probably not in every instance of every aplication I'll be running, but danget I dont want to have to wait for anything.
 
That's why i pointed out hardware raid vs. fakeraid. Fakeraid's overhead would be meaningless on a dual cpu anyway though.
