What's the point of SATA and 3 Gbit/sec xfer rate?

[JEDI]

sure sata is a little cheaper because it's 8pins vs ide's 40pins.

but hard drives have a mechanical limitation. it's platters can only spin so fast. 133mbit/sec is the limit.

flash drives use USB.

So what's the point of killing IDE, and creating Sata?

Tiny little cables > big fat cables

for the people that need to can use a port multiplier and add more hdds until it uses all 3gbit/s per controller

burst speed, there's cache on HD that can run closer to 3gbps

what?

sorta like a USB hub, except for sata?

133MB/s, that's 1.064Gbps, and right at the limit of UDMA133.

Now, some SSD's and future mechanical drives should be able to beat that (and SCSI mech. drives do, so I suppose a 15K SATA drive would too?), and you begin to see the reason for the headroom.

That and IDE cables suck.

Another perk of SATA over IDE is no master/slave setup problems.

It is a big mistake (like putting a Blinders) to evaluate a component in isolation from systems.

You can not reflect every thing in life through isolated "speed" capacity (that any time is Not even ans issue).

SATA is advance in the technology by using SATA it is easier and more reliable to build Motherboards, Laptops, External Storage devices, and more.
