for non SSD drives would there really be a noticeable difference in speed between this and USB3.0 or would the drive's own speed negate the benefit?

I bought this for my iMac that did not have USB3. Hence, I cannot benchmark it against USB3. It performs as expected -- very fast. I can keep the drive saturated with writes at 125+ MB/s. I am happy with the purchase.

USB 3.0 is a much faster connection to a computing device. USB 3.0 is about 10 times faster than USB 2.0. USB 3.0 is downward comparable with 2.0. One can plug a 2.0 device into a 3.0 connection, but will get only he lower speed of the 2.0. Conversely you can plug a 3.0 into to 2.0 receptacle, but you still get the lower speed of 2.0

They claim it is a USB3, I even questioned them about it, but it does not seem to work any faster than a USB2. It does use a USB cable. It is a good drive and is probably limited by its read-write specs.

The drive would be compatible, but I am not seeing a dramatic increase in performance.

Based on when this was introducer, I doubt it's USB 3. If your internal storage is either flash or SD, it really doesn't make much difference whether you have USB 2 or USB 3 port speed - the storage element write speed will be the gateing item.

If you are using an older machine that does not have USB 3.0 support the slower transfer rate can cause an issues such as this and there is no fix. If you are using a USB 3.0 port make sure your motherboard drivers and bois settings are up to date. After trying all this if the drive continues not to perform to your expectations I would exchange it for a different one.

I bought the 480GB and the speeds are pretty awesome read about 6GB (SSD) and the 250 (originally built in) over USB 3.0 about 3GB/S Hope this helps

Summary: all functional tests were fine but no speed tests. Used it with a Samsung 840 Pro SSD, 256GB. Tried it first on a Windows 7 machine to delete the partitions. Moved it to an iMac with Mavericks and installed OSX to run externally on the drive. The machine boots and loads software much faster through the external USB port with this case/drive than from the internal 7200 RPM drive. While a SSD is faster than the hard drive, the internal SATA port is much faster than USB3. It comes with a Y cable, one for the USB signal connection and a second thinner cable for extra power. The power cable is not needed with the SSD and I suspect it would not be needed with one of the slower 2.5" hard drives.

The drive is used for dvd backups and picture storage. When the old drive failed, I purchased another USB 3.0. That didn't help. I recovered almost 1 TB in two days. Then, since I had not yet received the new 3.0 card, I tried using the USB 2.0 to transfer from another backup (a western digital) to the Seagate. In 3 days, I moved about 300 Gb. That was left on 24 hours, too. After I got and installed the new 3.0 (I still doubted the old one), all remaing 500 plus Gb moved in less than 3 hours!. I never measured or recorded the speed. And the old 3.0 USB worked similarly.

It really doesn't matter, because no CD/DVD drive is going to send or receive data faster than USB 2.0 can comfortably handle. Having a USB 3.0 connection would not speed up the drive's performance. (As pointed out elsewhere, USB 3.0 ports are backward-compatible with USB 2.0 peripherals, so the drive will work whether the port you connect it to is USB 2.0 or 3.0.)

Yes, you can use a 3.0 flash drive in a 2.0 usb slot. I would be faster if you have a 3.0 slot. You can tell if the slot is 3.0 by looking at the slot, if it is 3.0, it will have SS next to the slot.

Hi Bandi, Technically, your drive is capable of making disk-to-host transfers of up to 110 MB/s, and USB 2.0 maxes out at 60 MB/s, where USB 3.0 maxes at around 125 MB/s. Your drive will probably never reach 110 MB/s, but I would suggest using a USB 3.0 enclosure so that your drive can run as fast as it pleases. Besides, at some point you'll probably upgrade even your "backup drive", and you'll want the speed. On a personal note, I love this enclosure. You'll need to buy some little rubber feet from the hardware store to keep it from sliding around, but other than that, it's great! Jack

Another internal should generally be faster, as it's not hindered by USB speeds. But whatever burns put your main drive is likely to kill the secondary drive,too. The external is good for portability, but tend to have a shorter lifespan compared to a internal drive. ( That's why people say "mine has lasted over a whole year now". My current HDD is over 4 years old now.

I wondered the same thing when I bought it since I wanted to be certain of this. The manufacturer said it was "compatible" with SATA III, but that does not necessarily mean anything. The external interface is USB 3.0 and limtied to 5Gbits/sec max throughput, of course. Anyway, after testing with a fast 3.5" 7200 disk drive, I came to the conclusion that the drive internally is running at max performance for its platter write speeds - as you can see from my reported review. Unless I were to check with an SSD, I would not be certain of the interface, but my educated guess is that it is is an internal SATA III interface ... hope that helps!

I've had no issues with the speed of the unit. It really depends on the drives you use.

All flash drive speed will be throttled based on the technology you are working with. This ADATA drive works well with 2.0, but speed is reduced, in comparison to 3.0 USB speed. It's not the device, but the platform you have that restricts the high-speed.

USB 2.0 will be as fast as it was designed for. Inserting it into a USB 3.0 slot will only allow it to run at it max speed 480 megabits / second.
