Customer Ratings & Reviews

Benchmarking this drive right out of the package may be misleading. I'd never bothered with benchmarking until about an year ago when I had some problems with a solid state drive. Since then I have played around with benchmarking various devices. When I bench marked this flash drive the results were terrible, barely better than my average 2.0 drives. At first I thought it might be defective but then I thought to check the 32GB version of this drive which I always thought was quite speedy. I'd purchased it over a year ago. So I benchmarked now and its average speeds were not real great but the interesting thing was that the first third of the drive was reading well over 120MB/sec, well above the advertised rate. The last two thirds were about as bad as my new 64GB drive. That's when I remembered the narrow 120MB/sec read spike at the very beginning of that 64GB drive. The software that comes on the drive? Then I wondered if you only get full speeds to data that's been written. That is, those parts of the drive that have been used, written to or written to and erased. To test this I filled the rest of the 32GB drive and then erased that added data. The average read speed for the entire drive was now 127.4MB/sec. I filled and erased the 64GB drive and it now reads 116.7. Not quite as good as the 32GB drive but I'm happy. I checked some of the poor reviews of this drive and see mentions of poor benchmarks. Maybe this was their problem too. I've had no problems with the 32GB drive and expect none with this one. Good drive. Got it on sale, so great price.

good price good memory and size and capacity. Very convenient and portable. adaptable and works with all my systems and usb ports and computers.

Great value. SanDisk has never failed on me. Glad storage this size is now so compact.

Easy to use, holds lots of data and very affordable-great product

Great flash drive. Functions as any flash drive should.

Quickly transfer files to and from your laptop or desktop using this SanDisk Ultra SDCZ48-064G-A46 USB 3.0 flash drive that features a read speed of up to 80MB/sec. The 64GB capacity offers ample storage space. (Ten times faster than USB 2.0 drives. Write speeds up to 10 times faster than Cruzer USB 2.0 drive.)* *USB 3.0 port required. Based on internal testing; performance may be lower depending upon host device. This says it all. I am a SanDisk fan and have always found their products reliable and safe.

It is a small size flash drive with large capacity. I saved lot of pictures in it now. Easy to use and low cost, I like it very much!

Worked great for me. I used this to do a clean install of windows 11 on my laptop.

I have a bunch of what are now older, slower, smaller USB 2.0 thumb drives. The SanDisk ones have always worked well for me. Boy are the newer USB 3.o ones fast. Also fit is stable when I mount them on my laptop. I bought a fairly large one - 64GB - and recommend them. Bestbuy $27.99 sale. Most new PCs and MacBooks now have USB 3.0. It's nice knowing I can use this one for a few years and not regret it. Yes, I know a rev of 3.2 is coming, but they won't be out until 2017. Enjoy this thumb drive for two years or more.

I really liked the Sandisk 64gb usb storage! Ttransfers are very quick. I copied all files from an old pc to a folder on new pc. Took 5-10 minutes. The item was on sale for large discount. I returned to Best Buy and purchased another 64gb USB a few days later. I was unable to use a portable hard drive which downloaded for more than an hour, then I was unable to transfer data to the new pc.

Technology just keeps getting better. I have purchased 3 of these SanDisk 64GB thumb drives (one to replace a lost drive) and am very happy with the amount of data storage and the speed of file transfers. I use a red drive for my personal information and I use a black drive for my picture/video files; the colors makes it easier to know which drive I need to grab. And the price is such a good value for the storage devices. I'm considering purchasing more units as Christmas Stocking Stuffers.

I love this USB, it's fast, portable & not to mention a decent storage space. Not to mention I got it for a great price!

quick and easy to use. works well. great price. my go to flash drive

If you need extra memory for Video's, Documents, or projects for work this is the Flash Drive you have to have. The Flash Drive also comes with Software already on your Flash Drive that will help protect your Videos, Documents, and Work Projects from getting infected with viruses or software errors. This was the exactly the perfect Flash Drive I was looking for and buy in the future.

Small in size and very easy to use..plus the 3.0 is fast. Comes complete with locking software pre-loaded. A very good buy!

It is a great flash drive to use with my laptop and keep my important information safe in one area.

Fast, easy, quick to use, reliable storage, just plug in down/upload to drive, and that's it.

Love this brand! Great speed & value! Have bought several times before, never disappointed!

I was thrilled to find such a great deal on this flash drive. So far it seems to be working just as I'd hoped, fast transfer of files. The largest I've transferred so far has been around 300 MBs so I can't speak to very large file transfer rate. My one complaint which is that the drive doesn't stay "in" with the drive looped onto a small key ring. The hole seems too close to the slider mechanism so any movement causes the drive to slide open. The purpose of this drive for me was for traveling daily to college classes and I didn't want a drive floating around loose in my backpack. I'm concerned long term about potential damage. I wouldn't purchase this particular model again for the design flaw but it's still a great value. I would recommend this with the caveat that it's best for at home or office use, not for daily travel.

Great price for capacity and speed of Flash drive with USB 3.0
