PATA vs. SATA

[tjpark1111]

I bet its been discussed many times but I want some user opinions. Does the SATA interface itself really help in performance at all in real world usage?(games, disk defrag, etc.) I am really wondering because IDE can be found for cheap at B&M stores but these noobs keep saying you're a serious dumb one if you get IDE now. Aside from the smaller cables, hot swapping, etc., is there even a performance difference at all? As I understand it, I thought it was the drive's read/write speeds, rotation speed, cache, etc. that made HDDs faster, not the SATA interface itself, but it just seems like SATA drives are faster because better, faster drives are based on that interface.

1) No it doesn't.

2) If you've got the same physical parts then there's no performance difference.

One issue to look at is that a good fraction of the new motherboards only have 1 IDE channel, DVD drives are nearly all still using these so you're not swiming in ports.

You win.

Were it not for drives like the Western Digital Raptor, the SATA bandwagon would be much quieter. The plain fact is that SATA's additional bandwidth is practically useless when drives weren't bandwidth-limited to begin with, and that means the only thing it brings to the table is NCQ. And NCQ for home computers is about useless.

But drives like the Raptor, certain Hitachis, etc. that are SATA and perform well would still perform well if they were on ATA. SATA is not the magical ingredient; a potent drive is.

I still wonder why I havent seen any 15,000 RPM drives for SATA.
It would be nice if something came along that actually showed us how fast the interface could be. My 10,000 RPM raptor is nice, but not mind blowing.

I guess it could be that I'm not looking hard enough.

I think that's going to be SAS territory.

well i do get sata now because cable aren't broad and also the fact its easy to have a raid 5 setup with sata

The simple (small) cabling and the abundance of inexpensive raid solutions make SATA the win for me.

all the stuff that you guys said I tried to tell that newb and he wouldn't listen. well i got my proof now, thx for the replies.

It's my understanding that the new Perpendicular drives trickling out (or still only prototypes?) are tanglible faster than IDE and other SATA, but, of course, the perpendicular drives will only be available as SATA.

Barracuda 750GB available in both SATA and PATA. It IS a perpendicular drive

Most HDDs, IDE or SATA, have real-life performance of 50 to 60 MB/s. If you are going to get a new computer, SATA of course. But if you see some darn cheap IDEs, then why not IDE?

Have u ever heard a 15K RPM drive, they are loud, I doubt u would want one in your desktop system, not to mention it will require active cooling. if they had one available how many idiots do u think would buy one and stick it in there dusty cramped towers with no active cooling just to have the drive die in a year.
