Could someone please tell me what these types of HDD mean. I believe IDE is the *basic*.

The PC Mech front page has some articles (http://www.pcmech.com/hdindex.htm) on the differences between IDE and SCSI. SATA stands Serial ATA and is due to replace IDE soon. One big difference for SATA there are no master/slave settings, and the cables are much smaller.

Sata = Serial ATA which is the latest and greatest (so they say) uses a smaller cable and is bi-directional in data transfer. Current Hard Drives are still not that much better than IDE drives.
SCSI = The old way to have super fast data transfer and still the fastest way. Expensive and can be difficult to setup. Not really needed for the average PC.
IDE - Parallel interface, cheap, easy to setup, and all boards are equipped to handle them. With 8MB cache drives are fast.
Go with IDE or SATA.

isnt ata133 the same as ide?
133 is the burst transfer rate, this can be used for either IDE (PATA) or serial (SATA). UDMA133 = ATA133.

are there ata33/66/100/133 versions of sata or are they all ata133? What UDMa mode would scsi and sata be? i know mode 6 is 133 and such but would sata be 7? and waht about scsi? does anyoen know if there will ever be faster satas like 166 sata
SATA is ATA150 if the controller is in the motherboard ICH chipset, ATA133 if it's on a card or uses the PCI bus. ATA300 is gonna be next.
SCSI is rated differently according to the type of SCSI, Ultra 320 is the fastest now, this requires a 64 bit PCI bus. Ultra 160 is as high as standard PCI will go.

Where can you get a 64 bit pci slut, just wondering.

thats waht i meant. Thanks.
Is sata 133 faster than normal pata 133?

so sata isnt inherintly faster its just easier to get faster burst speeds with?

IDE (PATA) has reached it's peak at 133MHz where SATA has the potential to go much, much faster.
I think the increase in spindle RPM speed will do more for system performance than increasing burst rate speeds. Moving up from 5400 to 7200 RPM made a big difference in my own computer. I imagine the jump from 7200 to 10,000 RPM would be pretty noticeable too. I'd love to see how a 15,000 RPM SCSI hard drive would improve my system performance, but I can't afford SCSI.

In the recent maximum pc they say that upping the RPM means smaller HDD capacity. Which you can see in the raptors. 36 gigs, i laugh in thine face. I mean the Kia Rio (the car) its motor only spins in the 5000 range, so whose to complain about 7200, lol

There are 10,000 RPM SCSI hard drives with 147GB capacities (which cost around $700) so you can expect to see 10,000RPM SATA hard drive capacities increase eventually. The 15,000 RPM SCSI hard drives seem to top out at 73GB (which cost around $575).
And why are you comparing a car engine to a hard drive? I don't get the comparison.

Okay, but what are they all used for? Come on, I'm very interested in learning the stuff I don't already know. I'm very sure cricket could answer my question now

They are all just different types of hard drives interfaces.
The 73 gig Raptor is due next month. I'm guessing it will hit the streets at $299 and will be available for around $250.

Whats with the weird numbers? 73?
It's based on SCSI technology. SCSI has been 4.5, 9, 18, 36, 73, etc. Next step is 147.

so wont it just end up being more expensive than SCSI? Since its newer, and based on teh same tech?
The 36 gig Raptor is a bit less than a 36 gig 10K rpm SCSI, so I expect the 73 gig to stack up the same pricewise. If it were more expensive than SCSI, why even introduce the technology? It's no *better* than SCSI.

Sata is not scsi. There are differences in performance, reliability, and other abilities, generation of technology between the two being the same, scsi will outperform sata. At a price....

This is confusing me and getting me lost.
I have a IDE cd r and want to plug into a system im goin to build. The system use SATA so, will the components work?

As long as both SATA and IDE are on the board they will work.
