i have a 3-4 year old computer, with the following motherboard: Intel (Mickelson Trail) Q965.

how can i find out if this is usb 3.0 compatible? i bought a 2 Port USB 3.0 PCIe Controller Card, but when i use my usb 3.0 passport external hard drive, the speed is the same as usb 2.0.

thanks.

the speed is the same as usb 2.0.

Which "speed" are you referring to? If you're meaning the data transfer rate, ie how long it takes to copy a file to or from the drive, it's likely the drive in the enclosure has a sustained data throughput less than the level USB2 can already handle (theoretically around 60MB/s, although that doesn't happen IRL). Especially when writing to the drive, which is always slower than reading.

If it's this "performance" aspect, then unless the device was being held back by USB2, there's nothing to go faster over USB3.

by speed i meant how long it takes to read data. the results were: usb 2.0 (26 Mb/s), usb 3.0 (34 Mb/s).

when i used the program HD Tach, it gave these results for a sequential read test: usb 2.0 (32 Mb/s average, 36 Mb/s peak), and usb 3.0 (78 Mb/s average, 113 Mb/s peak).

it seems the test results with HD Track show more than a double increase in speed, but with my informal timing of transfering data showed much less improvement.

so in real life, it looks like the increase is negligible?

A 30% increase sounds reasonable to me, for a device that isn't stressing the bandwidth of USB2 to begin with. HD Tach will naturally report a higher potential performance increase from benchmarking just the drive itself, as this removes the rest of the process of writing the copy onto your computer, which takes the same write time whichever interface you use for the external drive.

So HD Tach measures how fast data can be read from the drive straight into memory, but when you're timing the copy process, it's also including the time taken in writing the copied file.

The 32MB/s gets slowed to 26MB/s by the writing delays, which the potential 78MB/s USB3 can't improve by the same amount, but there'll be reduced latency which brings to overall transfer rate up to the 34MB/s.

The base 32MB/s rate might be a bit low to begin with - what size and spec (model) Passport is it?

i have the following: Passport Essential SE WDBACX7500ABK 750 GB. i have a dual core 2.8 GHz CPU and 4G RAM. i assume the writing speed is based on those parameters, plus maybe related bus speeds?

The USB2 benchmarks you get do seem a bit lower than those I found in a review of a 1TB Passport, although a larger drive can have higher performance.

I guess the simplest way to check if your computer is the limiting factor is to see how the drive benchmarks on another computer.
