Serial v. Parallel ATA


Recommended Posts

I have heard a lot of hype about how much performance serial ATA was suppose to give you and I have been a little skeptical. Is it not true that an ATA-133 Drive is suppose to move 133Mb/sec, well it's more like 80Mb/sec because physically the heads cannot pull that much data off the platters so my way of thinking is why another controller upgrade?  Why don't we start working on making solid state drives a reality instead?  I had to be optimistic about this and see if adapting an old ATA-133 hard drive to a serial ATA controller would gain any performance.

Yikes! I was expecting a much greater improvement than that. I did like the cpu utilization though. So I think the message is don't shell out extra bucks on that new motherboard for the SATA, go for the standard version.

Guys: I just bought a WD Caviar 16bit 250 GB hard disk (WD2500KS). Do you have any experience on how to I can connect it internally without having to change my IDE motherboard desigened for ATA disks ? Also, have you any experience on connecting it externally via an ATA/SATA converter through the USB. Your thoughts and suggestions would be much appreciated.....Ravi :(

First off, that article was written in 2003. The WD2500KS is a 3Gb/s drive. That is 300 Megabits per second. That is MUCH FASTER than IDE. If you look on page 2 of the review you can see our benchmarks!

You can connect this drive and use it as just storage by connecting it to your motherboard. As long as you don't change your Boot order in your BIOS you won't change anything about your startup. If it were my rig, I would use that as my primary drive as it will give you greater performance over you older PATA disks.

I haven't connected any of these drives externally yet, and I don't think I ever will. (don't quote me on that)

Why wouldn't you use it externally, other than the fact that it requires a separate power cable, compatible motherboard and eSATA hba, lol?
