eSata interface + Ext HDD File Arrangement Settings
Freedom Kira:
USB 3.0 vs eSATA makes no difference; the bottleneck is the drive itself. The fastest mechanical hard disk drives can transfer at slightly higher than SATA I speeds (about 1.5Gbps). But, of course, against USB 2.0, either one is a better choice.
That is, of course, assuming that you are not using SSDs as external storage. That's kind of a waste of an SSD.
Also, for USB 3.0, you require hardware that supports it. If your externals can only use USB 2.0 and eSATA, use eSATA.
(By the way, by "case" I meant "computer case," not "hard drive enclosure")
I'm pretty sure that you can find an eSATA expansion that doesn't need a PCI slot, since it really just channels directly to the SATA port on the mobo. That's a better alternative than what I suggested earlier.
Don't think too hard; it's really not that complicated. It's basically connecting a SATA device externally with a slightly different connector.

esata is just a sata connector with a positive connector retention clip - it does not fall out.

Seen them for about $4 other places.

Im assuming you are using your external drives as storage and not using it for software. As long speeds doesn't cause video play back to skip then the speed shouldn't matter as much.
1TB HDD has a speed around 70MB/s to 100MB/s
2TB HDD has a speed around 80MB/s to 120MB/s
3TB HDD has a speed around 85MB/s to 125MB/s
HDD is still the bottleneck but only compared to the current interface being used. HDDs now do more then double then IDE and just about double of USB 2.0. If you are hitting 50MB/s on USB 2.0 then the interface is the bottleneck. If there any piece of hardware that I know it would be HDDs. I have spend a lot of time researching on speed and performance of HDDs to improve my system.
Another thing if you are using more then one external drive that is sharing the same USB port. USB ports on the mobo do split into two ports so if you are using 2 drives at once to write to the speed will be cut in half for each drive.
bork:
USB 2.0 can push about 480Mb/s and for a single hard drive, it hits about half the read/write speed of the faster hard drives currently out.
To get some higher speed into a external storage device, look into a USB 3.0 or a SATA 3Gb/6Gb connection. To support these type of connection speed, you motherboard will need it have it implemented or buy a add-on card with at least an available x4 PCIe slot (SATA 3Gb could live with a x2 slot.) At least a i5 with 4GB might be needed if you want to push the interface to its full speed.

if you're not in a hurry, you wouldnt mind 2-5MB/s speed of file transfer, if you're in a hurry, then just hardplug your HDD internally and be done with it. other than that, just fetch an eSata adapter and utilize that enclosure with an eSata support, dont ask, just do it! even a cup of coffee is more expensive than that adapter.... theres alot of types of them, theres a card type(uses one pcie or pci slot), theres a screw in slot type(it uses one of your slots behind the case, if you use low profile video cards, you`d know what i mean), theres a floppy slot type too(uses your floppy drive slot) and etc.
