Small Computer System Interface, a high speed media system of hard drives, used mostly in high end and server applications.
I get 10,000 and 15,000 rpm drives of 9,18,37, 50,73,and 100 Gb sizes, really cheap, on ebay and from salvagers of servers.
I also buy the controller cards and cables, and some adapters, the same way.
Pros: If you want a Redundant Array of Independant Drives, RAID, there are about ten defined cofigurations, for two to 100 drives, which all mirror one another, and continue to function even if one or two drop out, or get destroyed.
SCSI drives are typically warranteed to operate 24/7/365 in a stressful environment, for 7 to 10 years! IDE and SATA drives can do a 50% duty cycle, at MOST, and you'll see most are guaranteed for ONLY 1 year, a few for 3 years!
If you pay the premium, a tiny, rare amount of IDE or SATA drives, come with a 5 year warranty! These can cost you, as they need to be shut down daily, and that thermal stress kills Power Supplies, and other components in the computers! All mine run 24/7/365!
SCSI drives can read/write concurrently, up to 16 heads, which is fine for users of true multi-tasking and multi-user environments, even in the nome computer network, running GNU/Linux or BSD!
If editing video files, or composing and creating music, SCSI rocks!
Secure multi- backup! Very high speeds of data transfer, for multiple users. Only rivaled by the recently introduced SATA modus.
Can be HOT SWAPPED if you'll get the cage, caddy's, in an array server box, or an older Compaq or Intel server box off of ebay, for one...
I can daisey chain 14 devices (yeah, some scanners, Burners, and CDroms are SCSI, too!) per cable, and have glommed onto some controllers with two or even three ports!
Cons: There are 16(?) SCSI formats of hardware, and, it can be exciting getting all the right hardware to run smoothly.
Conclusion:
I run LVD/SE Ultra 320 stuff, but, after three years of purchases and installations, have had only one failure on a 9 year old salvaged Seagate Cheetah 10,000 rpm 18 Gb drive. I have invested about $0.40 per Gigabyte of storage in my 8 computer systems on this home network, including controller cards on 8 systems, and, 20 drives. Lots of folks just give the stuff away!
High speed SCSI drives make a bit more heat than do other drives, especially at 10,000 or 15,000 rpms! There might be a tiny bit of a shrill tone, upon spin-up...
GREAT for 64 bit computing!!! Great for NO DELAY of your music, or video, or games!
Love it in http://pclinuxos.com http://ubuntu.org and, http://livecdlist.com FREE isos of Linux, BSDs, that can really scream in SCSI!

it's not scasi it's SCSI (small computer system interface) it's like an IDE channel but it's much faster then IDE. It's use in Servers, Mainframes, Blade's.
Rair field ? don't know nothing about it Maybe u want to say RAID.
Search yahoo for RAID if u want it's very much to explain about it but i can give u something about it.
RAID is a controller that that connects 2 or more hdd's into a matrix. That can be set to mirror, or stream (mirror means that one of the hdd is visible and other is a real time backup). Stream is like you have 2 hard disks and you see then as 1. These are the most frequent settings of RAID. There is 0+1, 5, etc.

Guess this will help you to understand :
The common computer utilizes either ATA or SATA hard drives, as was discussed in this previous Tech Tip. There is another standard for connecting hard drives which doesn't find its way into too many personal computers, but is quite prominent in servers and high-end work stations: SCSI.
SCSI stands for Small Computer System Interface, and if you don't want to pronounce each letter individually, it's OK to call it "skuzzy." SCSI, like ATA (Advanced Technology Attachment) or SATA (Serial Advanced Technology Attachment), can be used for connecting more than just hard drives to a computer system, and some of the other peripherals that can support SCSI include tape drives, optical drives, printers, and scanners.
Cheers

do you mean scsi. thats small computer system interface. its outdated today. don't bother with this interface.
not sure what's rair field? unless you mean rare field. that something that's uncommon.

Good answers. I just wanted to point out that in Italy they actually are called SCASI disks. I was once riding in a car with an American guy in Italy, as he tried to phone in a configuration to a supplier. It was like an Abbot and Costello act.
... and two scusi drives.
scasi?
scusi...
scasi.
scusi?
scusi, scasi?
what?

NOW thats what I call song. the unique. what huge variety are they on now? Like NOW a million,547? That and Joanne Shennandoah (community AM. Singer) I were given them on my birthday, with a CD participant, i presumed i changed into the best.
