USB vs eSata vs SATA2

post #1 of 11
Thread Starter 
I figured I'd post the results of my hard drive setup just for information purposes. I benched 3 hard drives using HD Tach's quick benchmark. The drives I used are:

USB: 250GB Western Digital IDE 8MB Cache
eSATA: 500GB Seagate eSata 16MB Cache
SATA2: 250GB Seagate SATA2 16MB Cache 7200.10 (PWT)

USB:


eSata:


SATA2:


As you can see, USB (this is USB 2), chokes a hard drive beyond belief. If at all possible, use eSata for your external drives. It's MUCH better. This is common knowledge to many but I figured it wouldn't hurt to share.

USB is definitely not the way to go for devices that have been DESIGNED for another connector.

This concept also applies when people use USB for things like internet (connecting your cable modem by USB to your computer). All it's going to do is choke your connection.

IMO, it's silly that they tried to standardize USB for all devices, it's just not practical. Think about it. A CPU sucks for graphics rendering, why? Because it's standardized for ALL types of instructions. A GPU can ONLY render graphics, it can't do something like calculate your excel spreadsheet.

The other thing is, it's not like the nonstandard ports have ever gone away. Floppy drives still use their own little cable, IDE is still here, firewire is still here, our computers just have more and more ports!

Is the eSATA connector different than regular SATA connectors?

The connectors are different. Regular SATA connectors are L-shaped, and eSATA connectors are |-shaped. It is the same SATA, though, as in same cable and stuff, just different connectors at the ends.

Correct. eSATA is either a)outside the case, or b) close to the back of the mobo with a hole in the back to connect a sata cable from outside, or c) on an expansion card.

So what's the point of the different shaped connectors??? Also, how does the eSATA drives get their power? Do you have to snake a SATA power connector out from the case?
