Customer Ratings & Reviews

Initially bought this product for its size but I was pleasantly surprised by it's speed. Recommended if you have a USB 3.0 device. It really does show a difference.

I love these things it is a great way to not use up valuable space on your computers HDD cheep storage load files fast and easy to transfer if needed..

Excellent thumb drive. The Sandisk ultra 64GB USB 3.0 flash drive has very fast read and write speeds when used with an Acer Chromebook. Right now 64GB seems to be the optimum balance between speed and capacity. That will no doubt change as thumb drives expand beyond the current 256GB max size, but for now these are fantastic drives at a good price point when Best Buy puts them on sale. As far as I can tell there is no difference (other than color) between the Sandisk 64GB USB Type A Flash Drive - Red and the Sandisk Ultra 64GB USB 3.0 Flash Drive - Black.

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.

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

great quality products fast download easy to use great price

Easy to use and have a lot of storage. But is confused on how to save things

The flash drive is great, copies very fast for storage. Can back up to cloud. works on 2 types of USB ports. Slides easily to open and close.

We frequently use these large capacity flashdrives instead of CDs as they are much easier to write to, don't get damaged by dust or scratches, can be reused easily, and are fairly cheap. We send them to clients, always with good results (if they make it through the USPS). We have taken to sending these in a package instead of an envelope because despite several "hand stamp only" stamps on the envelope, the USPS will run these through the machine which causes the flashdrive to tear through the envelope and get lost.

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..

I needed a flash drive in a hurry, got this one at a great price

This an excellent 64GB capacity USB Flash drive made by Sandisk. The product quality is consistent with other SanDisk drives that I have purchased in the past. This Sandisk USB drive is easy to use and fits in well into the USB ports on my laptop. The drive recesses well with a simple slide of the thumb and appears to be well designed and sturdy. The price was quite good for a 64GB flash drive.

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.

Sundisk 64 Ultra drive is an excellent product and kept all my information

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.

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

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.

For the price it cannot be beat! Loads fast too! Also the pritective case is an added bonus!

I have loaded an insane amount of my Mp3s. 100+ Hours

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.
