ATA I, ATA II and SCSI

Hi, I'm looking to buy another computer and I'm thinking of taking the plunge into SCSI drives. I really like the 15,000 RPM drives but they're a bit pricey!
Anyway, a friend of mine told me that some ATA drives can run faster than SCSI if configured properly. Is there any truth to this?
Also, I've never installed a SCSI adapter, are there any tricks/configuration to it or can I just pop the card in
Thanks, Lana

If you set up a raid0 configuration I believe I can never remember the raid numbers. http://en.wikipedia.org/wiki/RAID but you have to have a mother board that supports RAID or you can use software but hardware is more desirable, also use SATA HD. I've never used SCSI because I believe that it's outdated by the sata. Anyone correct me if I'm wrong

First let me say I have never used scsi personally. I haven't looked into it for a while so who knows. SCSI is expensive, that's a fact, it's also not as plug and play as SATA as you need a controller card, especially if you have to boot from it, but it's not that complicated either. There are no SATA drives out there that can compare to SCSI, a 15k drive will have faster access time and i/o than even a 10k SATA. If you want a faster drive now, unless you can find a cheap scsi drive, your options are either with a single drive like the WD raptor, or 2 cheaper drives and a RAID 0 setup. You could put 2 raptors in a RAID 0 setup but it's not really worth the price. I would read this: RAID vs Raptor Read more about SCSI drives and get the prices but I can almost gaurentee that with using two cheap sata300 drives with a controller card capable of RAID 0 (unless already supported by your mb) you will be happy with both speed and price. Also SCSI has not been outdated by SATA, it's just that it's too expensive for the general consumer normally.

I wouldn't bother with RAID striping (RAID 0) unless you're doing video editing, that's the only thing that benefits from the increased write speed. Read speed is the same, or slower, as both drives have to do seeking.
If you can get ahold of one, look for a memory drive. There's PCI express ones, as well as SATA, PATA/IDE and SCSI, the fastest being PCIe, a controller board with DIMM sockets you can put ram chips into. It has a rechargable battery so you don't loose the data when you switch off your computer, and the read/write rate is as fast as the PCIe slot it's stuck into.
If I had loads of money, that's what I'd have. Instant load times? Yes please!

In the high end server world, we have mostly moved away from SCSI to SAS (serial attached SCSI). If I were going SCSI, this is the route I would take.
It is hard to make a recommendation without knowing what you are going to be doing. For more things, you are going to find bottlenecks in other areas of hardware that make SCSI vs SATA a pointless debate. However, if you have the hardware to back it up, a SAS array can be amazingly fast...

What kind of application are you plannin on using this for? Just out of curiosity.

Wha? RAID-0 increases performance during both reads and writes since you're bouncing between disk devices. Are you thinking about RAID-1 (mirroring) maybe? That gives slower writes (writing to two disks at once), but the read performance is the same (read from one disk). Some newer controllers will even read a RAID-1 set as if it were striped, giving better read performance.
The way to fly for video editing is RAID-3.

I'm doing statistical analysis of mortgage lending rates over a 30 year span. Interesting I know! (yawn)
The money is there for a good computer so I'm leaning towards one, possibly two SAS drives. Maybe a Western Digital Raptor. I'm still undecided.
