    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.

    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.

    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.

    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.

    Memory To Go

    It is a 32G thumb drive with a retractable USB plug, and it works. I don't run high tech tests, I can't tell you how fast it is, or if the power usage info is accurate. I purchased this one because it was a SanDisk, large capacity, portable stick memory with a protected port that retracts, preventing my pocket from destroying it. Now, the port can stick in the lip of the casing (not necessarily a bad thing), so if you chew your nails (I do) or have very short nails, be prepared to use a tool of some sort to jostle it out. But, it sticks in the retracted position, telling me that the port won't come out by itself inside my pocket, so maybe it was intended, Overall, I have had very good results with SanDisk brand. I haven't ever had a thumb drive from them go bad, although I do usually pass them on, or lose them within a month or so of purchase. Of those used for backup and filed away, I have never had an issue utilizing the data, even following years of stationary storage..

    Horrible customer service

    Posted
    VICK

    When I plugged in for the first time, it didn't work. I called the customer care and asked for a replacement. They asked me to send it to an address and I followed their instructions. I then received an email about a tracking number that a shipment has been sent to me. Neither I nor my leasing office had received a shipment and it started showing delivered in the tracking status. When called to inquire, the customer care representative spoke as if she was suspecting that I am not being honest and trying to get away with this "expensive" item! They said that they will ship a new product which I have not received a tracking number for till today! I have been a sandisk customer for years and I don't think I will be buying any sandisk product any more. After paying more money for expectancy of quality, if sandisk also can stop working anytime, why not just go for a cheaper option? Ya I guess I wont be buying sandisk any more. And neither will all of my friends at my university! I am sharing this story with all of my friends so that they don't waste time and money like I did!

    OK, getting the legal stuff out of the way: I've owned quite a bit of SanDisk products, and a mandatory disclosure is that I was once part of the SanDisk family (I worked for Fusion-io, who were purchased by SanDisk.) Moving along, I've been a fan of SanDisk product support even since my first and only support experience. I RMA'd a Dead-On-Arrival 64GB MicroSDHC card months after I bought it (it was sitting on a shelf for quite a bit before I got to it), and had a very pleasant experience replacing it through their usual customer RMA process (and at that point, they were no longer my employer.) I know that if a product of theirs has a problem, they'll replace it, with minimal fuss. Going for a fast, bootable, 32GB USB stick for my work travels from SanDisk was a no-brainer. And of course the fact that it's Ferrari Red doesn't hurt the aesthetics one bit. Good product from SanDisk, good price from Best Buy. Can't complain one bit.

    Locks in better than the older version (take more pressure to release it. when reach around to the back of a computer on the old style I would squeeze it and then it would retract as I'm trying to put it in, this one I don't have that issue. The shape looks to be rounder and looks much fatter than the old one but is more of looks, it is only slightly fatter and still fits if you have multiple USB's used usually with older computers. Easy as any USB to use. I use one for a windows 8 Restore disk on the 3.0 USB, and other for files etc. Got it on sale. In the picture the 2.0 actual looks fatter in this picture, but sitting on the desk the 3.0 looks fatter. I had to run a ruler across both of them to make the ruler tilt to see how much fatter it was.

    Great Sale Price for SanDisk Ultra 32 GB - 3.0 USB

    I buy all types of storage/memory media whenever I see a steal of a price. There are so many different devices out there worldwide, you'll find that buying different storage and memory will ultimately be needed, even if you don't think so. Alot of times you find that Zap, your storage or memory just fried or lost the ability to store. I had a flash drive from +10 years ago that lost its' ability to store. Like a CD or DVD, it is well known that data can "evaporate" based on shelf life. Having a box of various storage units (and memory), you'll realize what a great idea it was, as soon as you need it later on, when the item is no longer sold. I had this issue with a +15 year Olympus Digital Camera. Nobody sells the extra large size card it takes anymore, and mine failed, but I wasn't worried, I had a backup I bought a few years ago. If it's a good brand and the price can't be beat, buy it, you'll be very happy later on.

    So far so good, it only cost me about $6 on sale for the 32gb one and it works great. I can transfer a 1gb file in about a minute as opposed to the 3-5min it would take before on a usb 2.0 stick. I've only had it for about a week so far so I can't say anything about it's durability just yet, which is a known problem with some flash drives. One point of warning though is the connection feels visibly warm after just a few of the larger transfers, much like if you used a 2.0 over a long period of time. I guess the faster data transfer means more heat and electricity passing threw the stick so I would advise long continuous use, if you want that get an external HD. And in case your curious USB 3.0 is backwards compatible with 2.0 ports, it just doesn't gain any extra speed while using them.

    Cheap USB 3.0 Flash Drive - Not much more to say

    • My Best Buy® Elite Plus MemberElite Plus Member

    The SanDisk Ultra 32GB USB 3.0 Flash drive is what you would expect for about $10 dollars. While it isn't super small like many of the PNY drives, it's read and write speeds are much better on average and those read/write speeds won't degrade as quickly overtime as the many of the PNY flash drives are known to (performance will often will drop 50%-75% within a year). Again, this is on of SanDisk's budget flash drives, so don't expect speeds anywhere close to the claimed 100 MB/s speeds. If you want speed like that, take a look at the SanDisk Extreme line-up (realistic speeds between 100-150 MB/s) or the SanDisk Extreme Pro which is blazing fast with read/write speeds close to 200 MB/s. But all that speed comes at a cost. I just needed to store some documents so those drives would have been major overkill.

    Ideal for HD and UHD video playback

    Most Televisions today and devices like the ROKU Ultimate have support for HD and UHD video playback from USB devices. To insure stutter free play of UHD video you will need USB 3.0, 60Mb/s performance out of the device. This gives you a reasonable margin while allowing 60 fps UHD video to play smoothly. The lowest cost device I've found for this purpose is the SanDisk - Ultra 32GB USB 3.0 Flash Drive which provides for playback at up to 90 Mb/s and read speeds up to 100 Mb/s. With my Roku Ultimate it provides fast access and flawless playback of UHD 60 fps video with Dolby Atmos or DTS:X audio.

    I purchased this drive to create an external copy of new Windows 10 upgrade before permanent installation on my lap top. Unfortunately, I encountered hardware problem with my first purchase of product. I had to return to my local Best Buy. The exchange went super smooth, used the pick-up at store method. I found the designated parking (customer pickup only) spot and I was in and out with new USB flash drive in no time. The first one must have been defective, because the 2nd one worked perfectly. Easy to use and not complicated to understand instructions. You just need a USB port and then just insert. I really like the retractable feature which keeps data safer. No more caps or covers, just slide the the connection forward and pull it back when complete.

    I bought a couple of these thumb drives because they were at such a good price for USB3 drives. I was converting and transferring old 8mm films of my kids to digital to give the videos to them to both bring back memories and to show their children what their mom looked like when she was their age. I was surprised on how fast those large files transferred to the drive compared to how long it took when I first tried to copy the videos to an old USB drive. That ended up being too small to hold all the videos prompting me to buy this larger 32bg thumb drive. I sent these new thumb drives to my kids and each played the videos on their PC's without any problem even though their PC's didn't have USB3 drives. Worked perfect. Now I wished I had purchased more of these drives at the time. Highly recommended

    Nice amount of storage for the price. Very compact. 3.0 is very fast compared to standard 2.0. I have actually purchased several of these USB sticks. I used them to install Windows 10 on my latest computer. I downloaded Windows to one USB stick and all of the drivers to the other before the installation process. With USB 3.0 and an M.2 hard drive on my new computer Windows 10 was loaded and up and running in about 5 minutes! Drivers loaded in a flash from this USB stick. I like having a couple of these around, many uses for them. I trust SanDisk reliability over other memory.

    I bought this as a Christmas gift for a loved one. While I like LG tvs, the one thing they miss that both my converter box and Insignia tv has is the ability to read a summary of the tv show I am viewing and also see a listing of the tv shows that will air in the next three hours on the channel I am viewing. I don't have cable tv (refuse to get it), so this option is a wonderful feature to have. LG needs to consider getting it. I purchased an LG for myself about a few months before the converter box requirement for non-digital tv (I have one in my house), and was hoping that tv show summary and programming preview was a feature that was going to be added in the near future. Seven years later and I have yet to run into a LG tv with the features.
