SCSI 7200 vs. IDE 7200

which do you think would be the better solution, let's say both drives are the same size:

A SCSI 7200 drive with 9.7ms seek time, or an IDE 7200 with anything under 9.7ms seek time (lets say it's an ATA/100)?

Which is the better choice? Thanks!

 
I guess it really matters what you want out of the computer. Both of those respective hard drives look like they'd be *roughly* equivalent in speed, so in this case I think I'd just go with the IDE because it's cheaper.

If you goal is maximum data transfer and the fastest seek time, high end SCSI (IE: $$$$) makes IDE look like watching paint dry. If, however, the utmost speed isn't really an issue (and 99.98 percent of the time it really isn't) then IDE's are much more cost effective and generally less picky/sensitive. SCSI can be a real pain in the neck if things aren't working right.

So I guess you have to ask yourself what you want.

On a side note, SCSI CD-ROMS whip IDE ones left and right. I'd have a hard time giving up my plextor, because it schools my brother's IDE at ripping audio and data.
 
Thanks Misterduck.

I've already purchased the SCSI from ubid.com. It was dirt cheap. 9gb for $40. I'm going to use it only for the OS (XP home) when I rebuild my computer.

But I got to thinking about maybe ditching that and going for a 20gb 7200 IDE with faster seek times. I could always sell the SCSI on ebay and recoup the cost. The extra cost of the 20gb over the scsi isn't much of a concern.

Since it will host the OS and programs, should I ditch the SCSI and go for the IDE?
 
depends what the "problem" is
given the exact same access times and str's, the overall speed of the system with be likely marginally faster with the scsi, but maybe not enough to justify its purchase
unless you need higher reliability
 
sorry, post got screwed

unless you're running a server and have multiple i/o's
if it's just for a home use, unless you're going to get a fast 10,15k, or you've already got a scsi adapter and can get the drive cheap, it's probably not worth it.

i've bought a couple of ubid scsi's myself. while not bad, if you have an older generation 7200 scsi, their performance may not equal a cutting edge ide

spring for a quantum atlas III for 200 as an os drive if you want fast scsi.
 
thanks guys...I do have a scsi adapter already, as I currently have two 4gb 7200 scsi drives. They are old, from about 2 1/2 years ago. I don't imagine their seek times are very low by today's standards.

I can't afford to spring for a 10,000 rpm scsi, so I may opt to get the ide 7200 and sell the 9gb scsi when it arrives (if anything, I could still put it in the system as an extra drive, can't hurt and it was only $40!
