ATA 133 vs 100

I just order some new ATA 133 IDE cables im wondering if it will effect the performance of my harddrives i have a 7200 rpm maxtor and a 5400 rpm WD caviar?

What im doing is replacing my old ata 66 IDE cable for my cd rw and dvd with my old ata 100 cable and buying some new ata 133 cable for the hard drives so will this help with my cd burning speeds and and drive access time a noticable difference anyways?

thx guys
 
um,, those hard drives will only go at the speed of the slowest. for example, if your 5400rpm is ata100 and ur 7200rpm is 133, it will only got at ata100 because it's the slowest one on the channel. i think. correct me if i am wrong though.
 
ATA133 is a marketing gimmick (and so is ATA100 for that matter).

The fastest IDE drives on the market barely surpass proposed ATA33 levels with sustained transfers. I wouldn't waste your cash on "special" ATA133 ribbon cables; they really won't do a thing for you.

That is true to some extent, but ATA133 actually brings the ability to handle drives over 127GB in size. The thought of maxing out 133MB/sec with two drives is just silly though. It's not going to happen any time in the near future. Hardrive technology seems to move much slower than CPU, video card, memory, or any other technology for that matter. It's too bad, harddrives really bottleneck a lot of tasks.
 
Ku, If ran on an ata133 controller (either pci card or on-board motherboard controller) and appropriate cable it doesn't matter what the other device is running...modern chipsets can correctly set to each individual device. That example was true a few years ago, but not now...

I agree that most ata133 drives will most likely do sustained transfer rates of around 40-45mb/s with some burst of speeds hiting near the 133mb/s range. So not much of a performance enhancement. I notice that each time the rives are climbing in udma rate and size of platters the drives access times are reducing and that can help...

Good lord!!! someone actually agrees with me!!

While it is actually not just nothing... the practicality is 99.9% nil. If anyone buys an hdd BECAUSE of the fact it's ATA/133 they're way off... I would rather have a 7200RPM ATA/33 than a 5400RPM ATA/133. ATA/33 is all you REALLY need.. ATA/66 is about the highest that is actually used so to speak...
 
Getting new cables won't help your speeds at all. None of your devices are Ultra133 and even Ultra133 components are only marginally faster than their ultra66 counterparts at best. You'll need a faster burner if you want to speed burning up.
 
"correct me if i am wrong though."

That's not correct. IDE can operate drives at different specs.

"The fastest IDE drives on the market barely surpass proposed ATA33 levels with sustained transfers."

The newest WD 7200RPM reaches 50MB/s which is well past the real world ATA33 max of around 29MB/s. You would definitely not want to run any current 7200RPM drive on anything slower than ATA66.

"I wouldn't waste your cash on "special" ATA133 ribbon cables"

There are no ATA133 cables, just like their are no ATA100 cables. Any 80wire IDE cable will work fine.

I believe Maxtor is the only company curently producing ATA133 drives, not surprisingy since they developed the standard. IBM and Seagate definitely will not be, I'm no sure about WD.

You will get a minimal speed boost as you bump up ATA standards even if the drive can't sustain that level. There will not be much boost at all going from 100-133 as you run into PCI limits before you hit the ATA limit. An increased burst limit of 10-15MB/s at those speeds is a very small percentage. If the drives had larger caches, like the WD special edition, the increased bus potential would yield larger overall performance increases.

If you have two ATA133 drives on one channel, can you split the bandwidth in half and transfer from two drives simultaneously like SCSI can?
