What are the USB 2.0 read / write speeds for this one?
2006096
Per a review by PC Magazine on June 21, 2012, after it was first introduced, this USB 3.0 drive out paced its closest competitors, even running on a USB 2.0 connection. On a USB 2.0 connection it tested out at a 29.5 Mbps write speed versus about a third that for each of its two closest competitors at the time (Kingston and Verbatim). Similarly it produced read speeds of 31.7 Mbps, about one and a third to one and a half the speeds faster than its two closest competitors. And course it REALLY soared on a USB 3.0 connection! SanDisk makes this drive in three sizes: 16GB, 32GB, and 64GB. While they are essentially equivalent, there are apparently very slight performance differences due to size and configuration. PC Magazine noted that when running on a USB 3.0 connection they might have been running so fast they were bumping up against the limits of their test PC. (I really love my own SanDisk Extreme 64GB!)

It claims 3.0 but the read speed is determined by the card you put in it more than the 3.0 USB. I get similar speeds on either bus.

Sorry, I haven't had a chance to try on USB 3.0, but, I know it's faster compared to my other WD Passport 2.0.

Yes, this drive functions on USB 2.0 ports but the file transfer speed is a bit slower.

The Write speed was between 9.83 MB/s and 14.43 MB/sThe Read speed was between 64 MB/s and 78 MB/sI have the 16 gb and I used usbflashspeed for benchmark

The box only mentions USB 2.0. I would guess a USB 3.0 should be ok, just won't get the 3.0's speed rate for data.

Yes! I have USB 3.0 and 2.0 I really can't tell the difference between the two in speeds...

I'm surprised most people have not noticed this being USB 2.0. To achieve anything close to advertised AC speeds you need 3.0 at best.

The transfer speeds are only as fast as the weakest link(s). For most cases this weak link will be the maximum speed of USB 2.0 itself or anywhere from 30mb/sec - 50mb/sec. This is not the fast speeds that this usb 3.0 manufacturer boasts, but it can only transfer at the usb 2.0 speeds if that is what it is plugged into. However a Usb 2.0 older tech thumb drive I have only transferred speeds at 7mb/sec - 15mb/sec, so this is still a significant improvement. Other factors of speed transfers are determined by formatted allocation sizes, ssd vs. non ssd, etc. I have learned recently to format drives of the same capacities to match the allocation sizes or maximum 2x and 4x. For example a 64gb thumb drive format to 64kb, (2x)128kb or (4x)256kb. The more kb = more speed and performance, but this will cause the drive to take up more space with written data blocks. So, a 2gb file transferred to a 256kb formatted thumb drive may take up 2.1gb of space, because the 256kb block sizes will hold a smaller size of data and occupy the entire 256kb block size.

I'm getting just under 130MB/s read and write. It took under 2 hours to copy some files (around a TB) that took seven hours under USB 2.0.

These drives are kind of strange. It transfers off the drive at high speed (~20 MByte/sec) but only writes at ~2 MByte. So I think it's USB 2.0 but the internal flash management chip on the drive must be pretty inefficient so it can't keep up with the comm. speed when it's doing write operations. Delete operations are also really slow. So overall I probably wouldn't recommend this product. I got them because they were cheap and I don't need high performance for what I'm using them for.

The answer to your speed question is not cut and dried. Generally, you will find USB 3.0 to be the fastest.This page has a good explanation: http://www.itworld.com/hardware/98987/usb-30-vs-esata-is-faster-better

IT seems it is USB 2. I have had no delays or problems loading up 15 gig thumb drives or with other USB devices.

Of course. USB 2.0 will never match 3.0 speed. When the drive worked read on 3 was at least 4 times faster

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.

The PNY Turbo Plus Attache USB 3.0 Flash Drive (32GB model) reads as fast as 140MBps* and writes up to 70MBps* . (From Google search)
