    This SanDisk Ultra USB 3.0 Flash Drive works exactly as you would expect it to. Transfers to and from the card seem to work quite quickly. The drive is about standard size, and like many others, has a slide button to slide the USB connector in and out. It also has a blue light that indicates readyness, and transfer activity. The drive is labeled in a way that makes it clear which side needs to be turned up for it to be inserted properly. (I hate drives that you have to try one way, and then the other, because you can't tell simply by looking at them which side should be turned up.) Finally, there is a molded, hole, in the curve at one end, to allow the drive to be carried on a key chain. The one negative I found, which is the reason this is a four-star and not a five-star review has to do with the software on the drive. There is an executable that I believe has to do with drive security. When I ran it, it recognized that there was an update for the program, downloaded the update, but then the update would not run. I paid full Amazon price for this flash drive. I wrote this review just to try to help others learn a little about it. I hope you found this review helpful. On the other hand, if you did not find this review helpful, I’d be interested in hearing why, so that I can attempt to edit it and make it more helpful to both you and others. If you leave a comment on the review, suggesting how it would be more helpful, I promise to respond to your comment, and to attempt to incorporate your suggestion in my review, if it is at all possible for me to do so. My goal is to write reviews that help people, as I have been helped by the reviews others have written. Thanks!

    Great for large video/photo transfers

    This is more expensive than USB 2.0 sticks of the same capacity, but the much faster speeds (about 10 times faster than a 2.0 stick) are worth it if you transfer large numbers of photos or large video files. A transfer to the stick that took two hours with a USB 2.0 stick takes only a few minutes with this one. Make sure that it is actually in a USB 3.0 port, though; it will work in a USB 2.0 port, but only at USB 2.0 speeds (approx. 10% of the speeds achieved in a 3.0 port). Not all computers have a 3.0 port, and some (including mine) have both 2.0 and 3.0 ports. Also be aware of the fine print on the package; the 100 MB/s speed advertised on the front of the package is read speed, not write speed. Actual write speed (on my high-end laptop; results may vary) is about 35 to 40 MB/s when writing a single large file (e.g. a video), and around 20 to 25 MB/s when writing small files (e.g. photos). I'm not sure I would pay full price for this (I used $15 in reward certificates, and normally don't mind waiting a while for a transfer at 2.0 speeds), but for those who lack patience, have limited time, or simply can afford the extra cost of this stick over a 2.0 stick, it's well worth the price.

    Excellent Performance in form-factor class.

    Admittedly I am along-time Sandisk fan but recent and SNEAKY changes to the Mfg warranty to many of their memory-cards has made me re-evaluate that stance. This drive features a somewhat standard feature for many USB 3.0 drives... backwards 2.0 compatibility and retractable male port. THE GIST: --> The build of this product is plastic (ABS-like) and is extremely light, BUT feels durable to touch and has held up several months without any flex or fault. --> This device is offered in the very visible RED color and BLACK color... which is great for buying multiple drives. --> Like other USB drives the included lanyard.... is NO LONGER included any longer. This shouldn't be a surprise at this point. --> Speed has been quite impressive in benchmark USB 3.0 testing, and has outperformed larger form-factor competitor USB 3.0 and Sandisk USB 3.0 drives. My bench-marking through Crystalmark yielded: Sequential - read 119-126mb/s, write 24-38mb/s & Random 4K - read 5.9-4.6mb/s, write 1.8-1.7mb/s. VERDICT: This seems to be an excellent choice in this USB segment but I've recently reviewed the OTG (micro and full usb) version of this drive and I would recommend that product over this one for features and performance. If similarly priced and you own Android devices I'd recommend that one over this drive. In general I'd still pass on many Sandisk MicroSD cards but this product proves Sandisk still is a winner for USB 3.0 flash drives.

    May need to plug into back of PC case...

    Posted
    Andrepartthree

    Going to add my positive review to the many others for this device.. have only had it for a day so far but works exactly as advertised (if I don't come back and update this review even years from the time that I post it then assume that it's still working great ! ) ... loving the usb 3.0 transfer speeds, I'd say it's about five times as fast as the old school usb 2.0 flash drives I was using. Having said that , you may find that these perform better when you plug them into the usb 3.0 port on the back of your PC ... which is a general observation that applies to all usb 3.0 devices not just this one in particular.. while it is indeed a pain in the butt to reach all the way back there, I find that plugging it into the front usb 3.0 port is "hit and miss" probably because that means you're dealing with the usb 3.0 cable for your PC case that plugs into your motherboard .... with the back usb 3.0 ports on the other hand (behind the PC) you're plugging the flash drive directly into the usb 3.0 ports hardwired into the motherboard meaning you can bypass any potential poor performance related to your PC case... This isn't to say my flash drive didn't work when plugged into the front of the case, matter of fact it was true "plug and play", Windows 8.1 immediately recognized it and had it up and running very fast ... I'm just saying sometimes it would seem to run slower than it possibly could with the front ports...

    Finally my private files are safe

    Finally, I can keep my private files safe and not have my mom find out about them, you know? My name's Eugene, and I have my own personal computer, but still my mom goes on it to pay her taxes, and I am worried that she will stumble across something she's not supposed to. So I bought the SanDisk - Ultra 32GB USB 3.0 Flash Drive, and let me say, this thing is a dream come true. I can plug this baby into my PlayStation 3 and watch all my favorite private movies directly on my big screen Samsung TV. There's even protective software that comes pre-loaded onto the drive so you can protect yourself from having strangers snoop your stash. The 32GB Capacity is great, and the front end slides back and forth to protect the device. Even my best friend Leet Larry loves it, because I can bring over my favorite private movies, and we can watch them together on his Xbox. The only thing I recommend is formatting it to NTFS, because FAT32 is for chumps, and usually won't let you put a high definition movie on it because it won't copy files of a gig. Most of the private part files I download are in 1080p and are roughly 1-2gb in size. I would highly recommend this product, as it's compact, has a robust amount of storage space, and is USB 3.0 compatible, making the transfer time super fast.

    Works well enough - no boot issues

    Due to Microsoft Windows 8 and 10 needing USB flash drives to create bootable recovery media, and also using several utilities (BooIt Bare Metal, Clonezilla) that also use/create bootable USB drives I purchased the SanDisk brand since I have never had boot trouble with this brand drive. One would think that all known brand USB flash drives would be fairly close in performance - yes maybe one is faster than the other, but generally functionally equivalent. Unfortunately I've had constant trouble with reliable booting from PNY (Inostor) 32GB USB 3.0 Flash drives. Given that the Windows Recovery disk is now a bootable USB flash drive, one cannot afford to have intermittent boot trouble with these drives. Thus my experiment with the less expensive PNY drives as bootable Flash drives has ended - and now I use SanDisk for these type of drives. You can still use PNY for data - I've never had a problem with lost data on a PNY drive.

    Big data storage in a tiny package

    I bought this flash drive initially because I noticed that it was on sale for a good price, while browsing my local Best Buy store. Specs: 32GB, USB 3.0 It is smaller than most flash drives that I have come across, with a retractable function that saves space and protects the part that inserts into a computer. The design even includes a cutout that would make it easy to attach to a keychain. The surprise came when I first opened and used the flash drive. It has a bonus "vault" feature, that allows you to have a password protected folder within the flash drive. It's perfect if you want to use it to share data with friends or coworkers, but have some files that you want to be kept private. Very intuitive and user friendly, and an excellent way to make this product stand out among the normally uniform crowd of flash drive storage devices.

    Extremely fast, made to travel

    I bought this product to hold text documents and presentations, but so far I've mainly been using it to transfer games, since the internet at my house is blazing slow. The first thing I used it for was to transfer Guild Wars 2, thus turning what would have been a week-long download for me (and probably three or four hours for someone with better internet) into a matter of three or so minutes. Given that the file size was around 23 gigabytes, this is pretty impressive. It is worth noting that the initial format of this flash drive won't allow you to put in files larger than four or five gigabytes, but you can fix this fairly easily by right clicking on it and going to format, then instructing it to convert to NFTS (just back up the proprietary software elsewhere if you plan to make use of it, because reformatting will wipe it). Once you do that, you can easily transfer files in the twenties of gigabytes. The retracting connector is also a nice touch. It helps ensure that the USB drive will not get bent out of shape if you stick it in a backpack with a bunch of other electronics or somesuch.
