|

Ok, next question.
I'm looking at possibly a new hard drive. I wanted to get one of those 15k rpm guys to be my windows & (online game of the day) HD. Now... I've been hearing that it won't just be a ribbon cable plug in, and that I'd need to buy a SCSI controller that'll plug into a PCI slot. Any truth to this?
How much does a controller run?
Could I get a new mobo that has a controller for SCSI built in, as well as standard IDE hd ability?

Why would you want a SCSI? These days with ATA-100 and IDE raid capabilities it makes no sense.
From a gaming standpoint a SCSI will do absolutely nothing for you. They are more expensive plus you need to have a scsi controller. SCSI's used to be great when they were the only RAID solution. There is a reason why PC's don't come with SCSI by default.
Stick to ATA-100 or whatever your MOBO supports.
However, if you are deadset on on buying a SCSI HD for whatever unfathomable reason, decide on the HD first, find out what type of SCSI it is, then look for cards. You can get PCI slot SCSI no problem, price will vary on what type of SCSI it supports. I doubt you will find a MOBO with integrated SCSI support outside of server MOBO's, which will cost you alot more than a standard desktop one.
Also, in case you don't know, SCSI HD's can be relatively loud compared to regular IDE HD's. I put my Cheetah in a standalone box and hid it behind the desk, it still drowned out my PC noise by a large margin.

You'll want SCSI, there are fewer I/O issues and it'll make a noticeable difference, prices vary head over to www.pricewatch.com and you can find something on the cheap.

serial ATA. SCSI might be faster, but it's dying out before it's a pain in the ass and so fickle.

you know..
15000 RPM doesnt really make a difference ..
the bulk of the read/write time on your hard drive is in trying to find where to read/write (the seek time) .. the RPMage is just how fast it reads/writes once it finds where it needs to go ..
a 15000 RPM hard drive is barely faster than a standard 7200 RPM one .. and dependant on the seek time it can even be way slower
if you want me to try and find my powerpoint file with exact info on how much seek time vs. RPM effect use time .. .. .. id say no because its a b***h to find

SCSI offloads the I/O to the scsi controller freeing up your CPU for other tasks.
Not really something you need for a home PC due to the fact you spend x4 more for SCSI than IDE for the same speed. Where SCSI really kicks in is when your reading and writing to several harddrives at the same time.
You can go cheap and buy older SCSI controllers and drives and yes ATA100 will be faster. Your best bet for speed on a home PC is a SATA-150 raid0 setup.

good points guys, I'm thinking from a linux perspective where IDE performance isn't as good as it is in the Windows world. If you're building a windows box, definately go serial ATA it really is the future of home based systems for sure. If you were going to run Nix though I'd defaintely say SCSI since its better supported then SATA atleast at the moment and would blow the nuts off of IDE.

i need a new hard drive 
my old imb was acting up, i thought it was just a windows problem ... bleh bleh
anyway, after a week of testing this, that, the other, and everything, hubby whiped the drive repartitioned tried to put windows xp pro on it but the bios kept resetting
then it happened, black screen of death (not blue). ran bios diagnosis = its toast, on it last legs not even good as a doner to spare comp or a server.
the old one lasted a good while and through three computers (upgrade rebuilds). so i cant totally complain, but loosing alot of stuff and needing a new one sucks
im on my hubbys comp now for the time being (should steal my video card and put it in his comp as its better).
so now im screwed as a new one isnt in the budget and wont be for a long time

If your mobo is relatively new, it prolly has 2 SATA ports on it. If you're really a spead freak but still want to keep it simple, get a a pair of western digital Raptor SATA drives, they spin at 10k rpm same as your basic SCSI, for less than half the price and no controller card added expense, their seaktimes are also about half of what a regular 7.2k rpm SATA drives are.
