Sata & Sata II data rates...

Just curious as to how Sata and Sata II compare up against the IDE western digital hard drive I have (7200 rpm 8mb cache).

as far as games loading, and general applications like adobe photoshop, windows it's self etc...

I believe sata transfers at 1.5 GB per second and Sata II = 3.0 GB per second?

Whats the regular IDE transfer rate?

what do you guys think..?
 
Ah, the marketing monster claims another innocent mind.

Newer drives are faster than older drives of the same size and speed.
Larger drives are faster than smaller drives of the same type.
The interface has little or no effect on transfer speed.
SATA II is mostly marketing hype for home users, ignore it.
IDE is being phased out, so for future compatability i'd go SATA.

If you want a speed boost then a newer HD can't hurt, but don't expect it to be massivly faster, a second here and a second there eventually builds up to a fair bit of your time saved, but it's not going to be all that noticable.
 
The speeds you list are the maximum theoretical transfer rates.

Comparable rates for ATA devices are indicated pretty clearly: ATA-100 peaks at 100 MB/s, ATA-133 peaks at 133 MB/s, and so on.

But it doesn't matter. Hard drives are not interface-limited. There's not a consumer hard drive on the market that can saturate ATA-100.

As stated, some SATA drives may perform better than what you have, simply by virtue of being better technology internally.
 
Well hehehe, one thing is for certain, this guy bought a SCSI 10K drive at this computer store i visit regularly, and the controller card had slots for ram, and they put 256 mb of ram into it, as a buffer i guess. That thing would load windows and games faster than anything ive ever seen in my life.. Are SCSI drives still the wayt o go this day in age for speed? Because this was like 5 years ago.

well... it depends 🙂 scsi drives are damn fast. When it comes to home computers they are the fastest. When you get into the server segment you have SAS drives (Serieal Attached Scsi), this will most likely become the new standard in disk drives on servers in the next year or two. As for faster drives there's always fiber attached if you got azz loads of money 😉
 
personally i will probably always run at least a 10k system/app/game hdd. i have run 15k(currently selling - too small 🙁) too, both scsi and they are fast, but it is a total option and price/performance ratio is not the best.

i like things to happen as soon as i hit the mouse button, and with 15k they do, 10k is a little bit slower, and i haven't run a 7.2k main drive in over 2yrs so i can't remember. that being said, it is a few seconds here a few seconds there.

everybody else swears by the raptors and they are good too. all i know is that when i game with some friends with bf2, even with my 10k hdd in i am always the top 5 in the map first and always in before my buddies(they have 2GB of ram and raptors, my rig is in sig). not that this means anything, but it is nice to get any vehicle you want first 🙂
