The fast SCSI drives are nice. I had one on my HP workstation and it's definitely faster , including booting up. I don't know that I would pay extra for it though.
If you want a fast HDD system, put together 2 drives in a RAID config. Ideally, use 4 drives so that you can use RAID0+1 or whatever it's called - striped and mirrored. That will be both faster and safer than one big drive. Areca make fast RAID cards. Mine works well with 4 x 250gb drives. http://www.areca.com.tw/products/pcix.htm Suss
Indeed, SCSI are faster, and you don't need a stopwatch to mesure the difference. But when i compare my tradingresults between my ATA period and my SCSI period there seems to be no difference.
I have the same set-up in my Dell Dimension 8300. It has not made a measureable difference, AND for what it's worth, who in their right mind wants to deal with a FRESH FULL INSTALL of an operating system? That takes hours. Not fun.
I got it down to 10 or 11 sec, after trimming craps out of the system and a small overclock on a P4EE 641 3.2Gz, overclock to 3.84Gz, massive heatsink, 2G 667 ram with heat spreader. Even the set the charts with less data today, felt like a 100% improvement, LOL A question comes to mind, should I go 2 x 10k on Raid 1 or 4 x 7.2k on Raid 0 +1 ???
Getting better, too. The new Corsair Voyageur GT is 2X faster than the prior fastest... and a 2G is only $29..... comes in 4G and 8G, also.
if you think a few moving average can still give you a R/R around 3, and be able to do it day in day out, then keep on paper trade Saxon22, coz you really have no idea how the market operates nowadays.
