whoa - I just discovered ATA100

So I've had an Asus A7V mobo (up to ATA100) since it came out almost 2 years ago - I think. Never got Promise controllers to work along with the existing WD 80GB ATA100(?) so I've been running on ATA66 all this time. Today I picked up the black Friday Maxtor 120GB ATA133 from BB and decided to give it another shot... I guess having XP this time around also helps... it detected instantly and I'm running at ATA100 baby! XP loaded up noticeably faster... woohoo !

Is the jump from ATA66 to ATA133 huge ? I may be due for a new mobo then. 🙂

you sure your old drive wasn't a 5400rpm and the new one is a 7200rpm?

WD 80GB was 7200 RPM also. It's now my slave... bumping an older WD 40GB out of the picture.

You CAN just get a 133 controller card you know!

I have one in my A7V 🙂

Hmm... how much does it go for ? And is it a huge jump in speed ? These speeds are really only access speeds right ? Does it have anything to do with transfer ?

lol.....

Can you say placebo? 😉

There are no drives, AFAIK, that can even take advantage of ATA66, let alone ATA100 and ATA133.

I'm not understanding this last sentence. I noticed all my systray icons were ready to go MUCH faster after my XP desktop initially appeared. There was a difference for sure.

haha, that's what I always thought.
 
Sorry to rain on your parade, but today's 7200 RPM IDE drives in no way reach above ATA66's sustained transfer rate of 66 mb/s. So jumping from ATA66 to ATA100/ATA133 is purely a marketing gimmick until faster hard drives are released. The "noticeable difference" which you "sensed" was a prime example of the placebo affect.

*Edit* damn too late

lol .. why don't you remind us how long before it really utlizes ATA 150. Hell, let me know when we start saturating ATA 100

Let me get this straight, you had an oldish WD drive, you update it to a latest gen product and you think that the speedup is due to changing the interface 😕
Odds are the speed up is due to the massively larger areal density of the new drive, probably lower seek times, and likely larger buffer, not the updated interface.

ATA66 would probably be barely limiting your new Maxtor drive if at all, 7200 RPM drives are just now reaching 60 MBps transfer rates and even then, only at the beginning.

No drives currently available can do sustained transfers of 66mb/sec, let alone 100mb/sec and 133mb/sec.

Are you sure it's not something weird, like you were in PIO mode before and you didn't know it?

The difference between ATA66, 100 and 133 is negligable. Since the drive cannot read that fast anyway, the only thing it effects is cache burst speed... It shouldn't have made that much of a difference.
 
Oh, I kinda skipped over the part where you're using a brand new drive.

In that case, I don't doubt that you saw a speed increase. The speed difference between older and newer generation 7200rpm drives is quite significant.. in some cases close to the 30% boost that the first move from 5400 to 7200 gave.

But yeah, it wasn't from the interface. 😉 Remember, our harddrives represent the biggest bottleneck in our systems. Compared to memory and chipset bandwidth, it's like going from the Grand Canyon to a longneck glass bottle.

Mechanical movement is glacier slowww .. at least compared to electrons. 😉

Guide ? 😀 Do the drive sizes have to be identical ?
 
It wasn't the ATA 100 that made your drive faster, it's because the new drive has higher platter densities leading to faster transfer rates.
