Compaq IDE HDD problem

Post by acaurora » Fri Nov 18, 2005 4:13 pm

I have a 6 year old Compaq Presario 1800T notebook, specifically an 18XL3, which has the following specs:

Pentium III 850
60 GB 7200 RPM HDD (Travelstar 7K60)
320 MB of RAM (256 MB stick, 64 MB onboard, yah weird I know)
6x DVD Drive
15" LCD @ 1400x1050
and.. the rest is rather irrelevant.

For the past 6 years I've used an 18 GB Travelstar that was horridly loud, and decided to upgrade the RAM / HDD after I started to extensively use it. However, one strange thing is that I thought that this laptop supports Ultra ATA 100 hard drives. However, currently I'm running Windows XP and the IDE controller reports only Ultra ATA 33! Can anyone help me as to figuring out if UATA33 really is the fastest that I can get on this, aka, is there a way to get UATA100, if it supports it? The 7K60 tops out from HDTach at around 33MB/sec, while the old travelstar did around 15 -.-...

Don't get me wrong, this thing is definately faster now, but UltraATA100 speeds definately would speed it up more.

Hard disk interface Ultra-ATA/100
Hard disk controller Ultra-ATA/33

Is what confuses me.

The way I would understand that is that the harddrive itself has an interface capable of Ultra-ATA/100, but the controller in the machine only supports upto Ultra-ATA/33. I don't really know anything about the Compaq laptop in question, but six years is a long time so I suppose it is possible that the controller really doesn't have the ability to do any faster speeds.

Looks like that laptop is based on the venerable Intel 440BX chipset. IIRC, the 440BX's internal controller tops out at Ultra-ATA/33.

How often will you need sustained throughput of 33MB/sec? Usually seek-time is a greater predictor of typical hard drive performance. The new drive will probably have a lower seek-time. I wouldn't worry about the ATA100, burst performance is not that important. UDMA2 will be fine.

Oh. Well, that kinda sucks. Have a fast HDD and a slow interface... oh well. It definately is zippier now, and quieter!
