Seagate Barracuda ST3500630AS 500GB USB 3.0 Bottleneck
Will my ST3500630AS Hard Drive bottleneck transfer speeds when I connect it to an external storage device which is USB 3.0 compatible. I've tried transferring files to and fro from an external storage device and I get 30 MB/s. I have the latest USB 3.0 drivers so why is it slow?
Hm... try running a hard drive benchmark, like this one: HD Tune. That'll tell you how fast the hard drive can run.
Alternately, you can just copy-paste a fairly large file on your hard drive and see how long it takes.
Thats an old 7200.10 drive. Top speed with data near the outter edge of the platter is about 75mb/s, dropping off to 65mb/s at half full, and finishing off to just under 40mb/s when full.
Yes this will easily bottleneck a fast usb3 drive, as would transferring lots of small files. You would probably see the numbers fall into the mid-teens with lots of small files on a nearly full drive.
Thanks for your answers guys! I think i'll buy an Intel SSD 730 series!
