This may sound stupid, but I haven't looked much at hard drives much, and figured I'd better learn something.
What's the difference between ATA, SATA and IDE?

ATA is IDE, well ATA is the connector on the mother board and drive, IDE is the data cable that connects them
SATA is serial ATA and is a bit faster like mentioned above, the connectors are VERY different

that could be too, i don't really know but if a drive or cable says its ATA or IDE there the same
if im correct
ATA= alternate technology attachment
IDE= integrated drive electronics
if im correct
ATA= alternate technology attachment
IDE= integrated drive electronics
I bought an IDE drive to save a few dollars. I should have gone with SATA soley for the smaller cable. I had a heck of a time installing my drive and trying to keep the fat IDE ribbon cable out of the way of air movement.
See the entry underneath the forum categories to the left?

Seriously, it's been discussed many times.

i heard that most if not all HDD's will be going to all flash memory in a few years
im glad i bought my IDE

IDE (Integrated Device Electronics)/EIDE (Enhanced Integrated Device Electronics)/ATA (Advanced Technology Architecture)/PATA (Parallel Advanced Technology Architecture): This is the previous generation of technology for communications between the motherboard and hard drives, optical drives, zip drives, etc. It uses a parallel interface which isn't quite as efficient or fast as SATA as you can see with the link that Cook1 provided. Mainly, because it sends 16-bits of data down the bus at a time and the timing for sending and receiving the data has to be perfect, otherwise the data will be corrupted. As a result, the whole process has to go slower to prevent this from happening.
SATA (Serial Advanced Technology Architecture): This is the latest and greatest communications method for hard drives. However, the technology hasn't migrated to optical drives so much yet. Yet again with a quick Google search and the link above it seems that SATA is better because it can check the entire instruction and data packet. And it can send it's single bit of information much faster down the pipeline then a PATA drive can. This seems to be because it only has to deal with one bit at a time instead of sixteen.
Hope this helps.

I went looking for info on SATA-II and found this Serial ATA FAQ.
If anyone knows the Reader's Digest version, i.e. what is the real world difference between SATA and SATA-II, please let us know. It looks to be fairly minor to me, nothing like a huge speed increase or anything. I did see an nForce4 motherboard that supports SATA-II.

I know that with ATA or IDE I can have 2 drives per cable. Is that the same with SATA or am I limited to to one drive per cable. I.E. Get rid of my parallel cable and have 3 HDDs on 2 SATA cables and 1 DVD burner on a parallel cable (since optical drivs do not have SATA connections).
I don't know why you bumped up a month-old thread to ask this (and did you read the part in the thread where they talked about searching???)
1 device per cable with SATA (but you can have more than devices/controller, at least with the more expensive ones). On the plus side, you don't have master/slave jumpers, and you don't have to worry about slowdowns while transferring data between devices on the same cable anymore. They also make SATA optical drives nowadays, if you hadn't noticed.
ATA is the official standard. IDE is a generic term that has been often used in place of the correct term ATA. Enhanced IDE (EIDE) is the WD coined marketing term.
ATA stands for AT Attachment since the IBM PC/AT was the first PC to use the ISA bus ATA was originally connected to.

Thats an incorect and half ASS answer! SATA, IDE, ATA are all very similar.
IDE stands for Intergrated Drive Electornics, It goes back to the old days of computing when hard drives did not have the electonics on board. When they found a way to shirink things they started to intergrate them on to the drive it's self. It was also a way of improving cost and performance.
EIDE- is an improvement over standard IDE as it alows the hard drive to directly access the system ram with out involving the cpu like IDE did.
ATA stands for Advanced Technology Attachment. ATA is an IO standard for PC's and got it's name from the old AT (advanced technology) style IBM computers. In modern days ATA now most often refers to the old paralell interface but is also avalable in a Serial version called SATA
SATA- Serial Advanced Technology Attachment. The same as Parallel ATA but send's data in a series of bits (kind of like single file line) one right after the other.
Serial Is faster than Parallel. Although a parallel interface sends mulitple bits at the same time, a serial interface is faster; Because a parallel interface has to be timed and the faster the data travels (ie ata100 vs ata133) the harder it becomes to time the data so all the bits arrive to their destination at the same exact time.

Until they figure out a better way of keeping everything synchronized. That'll be about the time when SATA is pushing the limits of what it can do - then we cycle back to parallel. Heck, look at the external interfaces - serial wasn't fast enough, so we got parallel ports. Then they weren't fast enough, so now we're back to serial - USB.

You are right, it is a funny cycle of things. But something tells me serial will last much longer than parallel if it does recycle. Serial has better scaleablitly than parallel. Just compaire the original rs232 vs IEEE 1284 and look at how well RS232 scaled as it matured.
This is incorrect too. DMA transfers were already in the ATA-1 standard. EIDE was never an official standard. EIDE is the name WD gave to its enhanced version of the ATA-1 that contained most of the improvements that the official ATA-2 standard would have before it was officially released, and some additional features including, ATAPI support, and dual controller support. Today EIDE means nothing as it contains no additional features vs the current official ATA standard.
Performance wise there is no difference at all. You might see maybe a slight advantage in a synthetic benchmark favoring SATA, but thats about it.

I also have a feeling something like that will happen.
