Customer Ratings & Reviews

Fast uploads. Will never purchase another 2.0 again.. More than enough memory for what I needed. Got it on Sale, very much worth the money..

The SanDisk USB 3 64 Gigabyte Drive is awesome! I use the SanDisk Flash Drives to copy and move data between computers. I also use them for storing data. I have been using SanDisk Flash Drives for years. I have never had a problem with SanDisk Flash Drives and strongly recommend them! :D

Came in and looks great. Works fine for work. Definitely recommend.

I bought these on-sale. They don't have a built-in activity light They do the job for cheap mass storage. The red color makes them easy to visually distinguish in a bunch of black SanDisk drives.

It's a thumb drive, or data stick, or a flash drive. Whatever you like to call it. It is speedy as advertised. I used it while upgrading some recent computers to save and transfer operating system and other ISO files. I now leave it plugged in as a mirror for photos and other media files that I need to take with me whenever I work away from home base.

What more is there to say then USB 3.0 speed, compact size, brightly colored, and a great price. I would buy this product all day long.

Holds tons of music files. I have 2100+ songs uploaded to one thumb drive with about 58MB of free storage space left.

Nice flash drive...decent size, decent speeds for both uploading and downloading, and easy to fit in your pocket. Good buy...

Yet another example of a fast, reliable flashdrive.

I liked so much due to the portability and keeping clean contact design

THIS IS EXACTLY WHAT WAS NEEDED FOR THE PROJECT AT HAND

So easy to use. I downloaded pictures from my phone and transferred the pictures to my computer. It is so fun going back and looking at the pictures.

Huge amount of storage and extremely fast. Compact and no cap to lose. I have flash drives with more storage but they are much slower.

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.

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

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

This product is compact and affordable. I like the idea that it's bright red so it's easier to see if I am digging through my bag and can't find it. Makes me life a little easier

great quality products fast download easy to use great price

Love it! It's easy to use and stores a whole lot of data!

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.
