SATA,EIDE,PATA...difference?

post #1 of 6
Thread Starter 
Hi,
You will have to bear me as i am a uber noob!
can i just ask, what's the difference between - SATA,IDE,EIDE,PATA Hard drives?
i mean if you had a PATA and a SATA running at exacally the same rpm speed and they had exacally the same storage amount ets, why would SATA come out on top?? (as i have heard SATA seems to be more popular)
Thanks

PATA and IDE are the same thing,they are actually PC IDE PATA HDDs. PATA is actually an old name for it SATA HDD's are in a league of they're own. They use am Serial connector rather than a Parallel connector hence the name. SATA came about as a faster way to transport data. In lab conditions an SATA HDD can transfer up to 150MB/s, PATA HDD's are what we all have seen since the dawn of computing, the large connectors that plug into the back and have speeds 33, 66, 100, 133. The Ultra-ATA's have 133MB/s rate but you will never see these results it's just what it is capable of handling.

SATA-II which came out just recently can transfer up to 300MB/s but real world results are obviously much less. ALL motherboard come with IDE controllers and most now have SATA controllers, but if you want fast SATA is the ay to go and the fastest is SATA in RAID-0.

The RPM is the amount of times the head of the hard disk spins. The faster the head the faster the computer and retreive stuff.

An SATA drive will beat any PATA/IDE drive even if it's a 10,000 RPM drive (which none exist), only the WD Raptors but those are SATA

I believe the Raptors are based on PATA, thats why they support both the 4 pin moldex and the SATA power connector.. basically a modded ATA drive.
Below... the dawn of SATA...
"What can be classified as a native SATA hard drive you might ask? With the exception of Seagate, every company took their IDE hard drives and added the Serial ATA interface to them. Seagate on the other hand designed their 7200.7 series around the Serial ATA interface and added certain SATA optimizations."

SATAII or SATA 3G is also NCQ (Native Command Queuing) and only MBs supporting SATAII can utilize that standard.

yup, as stated above, SATA drives transfer data faster. Makes gaming, installations, and saving large files much quicker.

Not all SATA drives will beat PATA drives. Yes the SATA interface spec. allows the drive to achieve a better burst speed (faster interface), but definately isn't any performance guarantee.
