Would using this flash drive with usb 2.0 limit the read speed significantly?

With this drive, the USB 2.0 read speed is 30 megabits/sec, and the USB 3.0 read speed is 255 megabits/sec.

Sorry, I made a mistake. The USB 2.0 read speed is 30 megabytes/sec and the USB 3.0 read speed is 255 megabytes/sec., i.e., bytes not bits.
1827011
Of course. USB 2.0 will never match 3.0 speed. When the drive worked read on 3 was at least 4 times faster

I suppose it would depend upon what you're attempting to transfer. In normal use, 2.0 doesn't differ greatly from 3.0. It does make a difference if you are transferring files of significant size (6, 10, 20gb). That said, I have been extremely happy with this drive's performance overall and I go back and forth between 2.0 and 3.0 ports all the time without any true impediment. I'm not sure that I've answered your question since I don't run any programs off my drive, but the transfer rate seems robust whether using 2.0 or 3.0.
1827013
Yes, it would. This flash drive would dumb down to the 2.0 speed which is significantly slower than 3.0 speed (nearly 10 times slower). However, nearly all newer computers have some of the 3.0 ports on them.

Yes. The limit is the speed of the usb 2.0 interfaces. But, if you use with usb 3.0 the speed grows up significantly.

Yes. USB 2.0 devices work in USB 3.0 ports - they just aren't making full use of the fast transfer rate.

You bet! USB 3.0 supports exponentially faster transfer rates, but it's also backwards compatible to work with 2.0 device connections.

If it has a USB port.....It will work like a thumb drive does......You don't need 3.0 USB.....It's a bit slower with a 2.0 naturally.....

My similar drive (5TB) is also equipped for USB 3, but it works great on my 2.0 ports. I assume it could transfer faster on 3.0, but there's no incompatibility.

Yes, it is backward-compatible with USB 2.0 and works on USB 3.0 ports. Your read and write speeds will be lower on a USB 2.0 port, but this will work fine with either USB version.

It's faster, but unless you know that your computer has a 3.0 USB port,better get the 2.0 reader.

Well I used to know, and was disappointed with the speed (less than like 40mbps read or write which is pretty bad for USB 3.0), but then the aluminum case was crushed by me simply sitting on it on a padded chair.... Would not recommend.

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.

You can use the cable that came with the drive (actually, you have to since USB 3.0 has one different end). It will automatically transfer data at 2.0 speeds.

Thanks, I'll look into how that is done. Also, can a flashdrive handle a program this large or only just files?
1997445
No, It needs to use USB3.0 for the speed, it will not work in a USB 2.0 port.
695275
Yes it will work in a USB 2.0 port, however you will only get USB 2.0 speed out of the drive when it is used in this way. To get 3.0 speed, the drive must be plugged into a 3.0 port.

Yes, I've used it in USB 2.0 drives and it works fine, a bit faster than a USB 2.0 flash drive but of course not the speed of 3.0 if used in a 2.0 port. USB drives are generally backwards compatible with earlier USB standards.

No. Connecting a 2.0 to 3.0 in any direction will always result in the lower speed of the two. However, they ARE compatible with each other, but you can only get a maximum of USB 2.0 out of this particular reader.

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.

If your computer has only USB 2.0 ports (rather than the USB 3.0 that this drive is designed to work with) you won't see a lot of improvement with this drive.
