    Performance & Benchmarks Below Average

    Disappointing, but adequate for moderate speed writes. Tested with Ubuntu Linux 14.04.2 on Sony VGN-NW270F using default Disks utility. My computer has USB 2 ports. Benchmarking parameters:: Transfer Rate Samples = 100, Sample Size = 10 MB; Access Time Number of Samples = 100. Results:: Averages: Write = ~12 MB/s Read = ~39 MB/s Comments:: Reads were fairly constant at ~39 MB/s with insignificant fluctuation. Writes spiked sharply between 12 and 7 MB/s. Access times were constant at ~0.99 ms. Conclusions:: I have a few PNY flash drives of the same capacity, purchased recently, that benchmark about the same on read and access, but are twice as fast on write. The waveform on the PNYs are square and may contribute to the better write speeds. The SanDisk had sharp points on the top and bottom of the waveform. I'm not an engineer, but I suspect the controller in the PNY flash drive may be more modern and advanced than the one in this specific SanDisk flash drive.

    Great storage for quick access

    Not much to say, other than it works for my needs. First, the one feature anyone these days should be checking for in flash storage is making sure it is USB 3.0 compatible. With the amount of computers, tablets, etc. utilizing a USB 3.0 connection, you'll thank yourself for having the faster transfer speed, when moving something like a few movies before a plane flight. It'll cut down the transfer time substantially from a traditional USB 2.0 flash drive. In other words, spend the couple more dollars to get the faster speed and always spring for the most storage you can comfortably afford, as opposed to what you think you may need. Its easier to have the storage there, then need it and you have run out of space. SanDisk is one of the leaders in flash storage so quality and performance have been great. I personally hold this on a lanyard for work because I deal with constant file transfers and application downloads throughout the day. Works perfectly!

    Fast drive that generates heat

    The drives are fast (> 100 MBytes/sec on read, ~30 Mbytes/sec on write but they get hot when doing large amounts of writes. I attempted to write ~30 GB of data to each of 5 drives simultaneously and after approximately two minutes the drives would go off-line. The problem was caused by overheating of the drives. I found that I needed to leave an empty slot between drives to allow the heat to dissipate. Without the spacing, my Anker hub was not able to adequately dissipate the heat. My other thumb drives don't have this thermal problem but then they don't transfer data as fast. Granted writing to 5 drives simultaneously is uncommon but my application is to distribute large files to many PC's via USB thumb drives. This is just something to keep in mind.

    Great value...imperfect design

    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'dn't purchase this particular model again for the design flaw but it's still a great value. I'd recommend this with the caveat that it's best for at home or office use, not for daily travel.

    The best flash drive I bought yet !

    Posted
    Chris

    This drive was reported by Crystal Disk Mark that it had a maximum speed of 165.7 MB/s in the test. I also transferred 21GB-ish of data from my 32GB Sandisk Cruzer Glide, which was a regular USB 2.0 Drive. That flash drive is a good one too. The data transfer took about 10 minutes! The time it took to transfer that data from my laptop to the 32 GB drive took about 25 minutes. I bought the USB 3.0 drive because I needed the space, and I just like sandisk. I have a 4GB sandisk Cruzer that cost $25.99 in December 2009 and it's still being used daily as my UBCD drive. Consider Sandisk for flash drives. however, it's also the warmest drive I have ever owned as it can get pretty warm when in operation, but not to the point of overheating.

    Great Sandisk USB 3.0 Flash drive 64GB deal

    The Sandisk USB 64GB 3.0 was a great buy. I purchased it on sale. It is easy to plug into my laptop's usb port. The flash drive downloads my files quickly. I like the fact that it is red, portable, large storage, light weight, has a 5 year warranty, and 100mb/sec read speed. The read speed is quicker than the black version. I am happy that I purchased it on sale. Sandisk does not included a key or a pouch to carry it. This is not a deal breaker. The regular price is expensive, but sale price was a good deal. If you need a portable lightweight, reliable brand, and with 64GB storage, this is for you.

    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.

    Pros: 64 GB on sale 20 bucks. USB 3.0 capable speedy upload/download times for larger files. Red and black Deadpoolesque color scheme if you treat your electronics purchases as fashion accessories, or you constantly lose thumb drives and want a highly visible one. Cons: No convenient key chain/necklace lanyard included to get caught on furniture, doorknobs and assorted junk in your work space. Slightly awkward usb sliding switch, doesn't allow Clint Eastwood quick draw word document uploading. Feels like Fisher Price designed the thumb drive housing.

    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.

    I bought a USB 3.0 stick from Staples earlier that same day. It performed better than my old USB 2.0 stick. I was in the middle of a project and had massive amounts to copy over to a new stick. Then I plugged in this SanDisk and started another copy to it even the the copy was partially completed on the Staple's stick. Wow - the copy to this SanDisk still finished quite awhile before the Staple's copy. Would buy again. One thing - the hole for adding to a keychain could be stronger.

    Walked into the store and saw this on sale, had to pick one up! :) Very fast transfer speeds using USB 3.0 (10x faster than USB 2.0) and lots of room for storage! It comes with a free code where you can go to SanDisk's website and download some software that helps you recover software if it's accidentally deleted. Durable build quality and a reliable brand. Definitely will have to buy a couple more next time I go into the store. Can never have "too many" flash drives! :)

    Having tried other brands and being disappointed this is the only brand I now buy for flash drives. Good transfer speeds, high capacity, and great value when on sale. I like the fact that this drive mounts as a Hard Drive as opposed to other brands that mount as a removable device. To me this makes the device more reliable. I have been using this flash drive for a few weeks now, and have many other SanDisk drives that are going strong after many years of use.

    I use SanDisk exclusively since over the years I have never had one go bad. However, the standard SanDisk thumb drives are very slow. It can take up to 30 minutes to backup 8 GB of data. The SanDisk Ultra claims to be ten times faster and that does seem to be the case. So with the increase in speed and decrease in price, it is a win win. After this excellent experience, I will only purchase the SanDisk Ultra. The Utra models do not cost much more.

    I have owned several thumb drives in the past but ever since USB 3.0 I have been in love with these things. The speed of these drives are insanely quick and being able to copy/backup data to these is a breeze. I use one for backup and safe keeping while the other I keep with me all the time. I will throw videos, pictures, save games, documents, music, and school work on these and not have to worry about space. Great investment!!

    SanDisk products have always proven reliable and long-lived in my experience, so they are a natural choice for me. In the case of this USB 3.0 thumb drive, it really zings along; the data transfer rates does depend, of course, on the speed of the source (or destination) drive, but this drive will not be the cause of any speed reductions, believe me! Makes an excellent drive for a complete system backup, too! Highly recommended!

    Reliable Flash Drive but slow to write

    Sandisk makes a good product, but the key is to look at the "Write speed," which is not always listed. "Read" speeds are almost always faster---usually double. The problem with "larger" flash drives for me is that I expect to store larger files, which makes the "write" speed equally important. In my opinion, if you have the extra cash, go for the "Extreme" line of Sandisk drives

    I am forever in need of a fast way to share work files between computers, co-workers, and locations. USB 3.0 drives like this one have the speed to make saving and reading files fast enough, the capacity is hefty (lots of graphic and CAD files eat up space quickly!), and it is convenient enough to pop one in the mail or overnight express when the files have to travel.
