can anyone tell me the story of serial ata.what it actually means.i know its a hard drive feature.but i need to know the actual facts about these types of hard drives and any of the previous/current/upcoming harddrives..
All I know is that they don't use the old 80 pin ide cables, they use a much neater, 4pin (i think) cable. It's also faster to access the drive, and you don't have to worry about putting a hard disk on the same channel as a cdrom, for example. So you can keep the ides for cd roms and still have fast hard disk and cd access.
its faster than ide and the hdds can go up 2 10000 rpm as appose to 7200 but u dou need a raid controller but on newer motherboards there often buit in but if not u can get pc versions. hope this helps dave :good:
Advanced Technology Attachement SATA has a peak throughput of 150MB/s or 300MB/s if it's SATA II. Now keep in mind this is a burst rate, not sustained, so it's actually not as big of a speed increase over PATA as you might think. You factor in spindle speed and cache and compare two drives that are basically the same other than the SATA or PATA inteface and you may not have as big of an increase as you'd think. Now the Western Digital Raptors are the sole exception. They run at 10,000 RPM, vs 7200RPM of most SATA and PATA drives available these days. Western Digital no longer has a SCSI line of hard drives and can afford to put up a 10k RPM drive. Maxtor, Seagate and Hitatchi have SCSI divisions that ATA drives running faster than 7200RPM could very likely impact their SCSI sales. Additionally, SCSI is a much more robust interface and designed to take a beating, so the prices aren't simply to grab money. SATA uses a much smaller data cable, which is good for airflow. Each drive has it's own port and doesn't have to share, hence the Serial part of Serial ATA. Parallel ATA (IDE) allows for a maximum of two drives per channel, but only one can access it at a time, and where you get the master/slave relationship thrown in.
i know i have a western digital 40gb hdd..how will i know whether i have a SATA or PATA? by the way,thx4 all da info..
SATA is better than PATA. Better cabling, better throughput, etc. Most of the latest mobos offer between 4 and 8 SATA connectors. SATA I is only 150, whilst SATA II is 300. But that's the theory. A lot of drives never see that much traffic. Raptors maybe the only drives that would benefit from SATA II interface right now. One thing I am looking forward to is SATA burners. Plextor just put some on the market. I'm sure the rest will follow. Right now I have a 16x PATA burner so I don't see a big reason to buy a new DVD drive until another speed bump. IE 32x DVD Sata burner would own.
