It seems to be a pretty good flash drive such as it is. It's a lot smaller than it looks in the pictures: 1 5/8" long. The metal seems pretty flimsy. I'm planning on keeping it plugged in though so that shouldn't be an issue. If you want something sturdy you can carry around, you might want something else. The Walmart ad and the packaging say USB 3.0 but my Device Manager shows it as USB 3.2 Gen. 1. It's responsive and the transfer rate seems pretty fast compared to my old USB 2 flash drive. I'm happy with it; Sandisk has always do right by me so far. I just got it yesterday so hopefully it keeps working.

Like almost all modern flash drives, this came formatted in exFAT from the factory, which may cause compatibility issues with older Unixbased OS. Its better to format it in FAT32 which limits you to 4GB transfer files or NTFS for maximum compatibility with those OS. And depending on how large the sector sizes are during the format I think it was 4096kB from the factory, your file size on the drive versus its reporting file size may differ. Dont be alarmed by a 1.7 MB file taking up 1.72 MB on the drive, thats because of the size of the sector chosen during the drives formatting.

I have previously bought this product from Tesco Direct, but they have since closed. Also, PC World Curries are too expensive, so this is a good price. The product is small, so be careful not to lose it. I use it at home so I keep it in its packet, so that I recognise where it is put. If you do keep it loose, then I suggest hanging it on a lanyard for safekeeping. Also, if it is kept loose then you may need something to cover the USB end since it is left open and it does not have a lid. The device is sturdy since it is made of metal, but if it is used for very long periods of time then it may heat up. I have used my ones continuously for 2 hours or so and they have been fine, but I suppose if they are needed for longer then you should transfer files in blocks so ... MoreI have previously bought this product from Tesco Direct, but they have since closed.

However, if it may be hot, then there is a black plastic beltbar on one end to remove the USB safely. My laptop memory is pretty full and it runs quite slowly compared to laptops these days, so when it comes to transferring files I do it in blocks to keep it running smoothly for an average pace, but a good speed with regards to the size of the device and its price. Another good reason to transfer in blocks is not only that it appears to transfer quicker, but it is more reliable. I dont know if its my laptop, phone or the memory stick, but when I try to transfer 1000 photos in one go, there is an error and I have to transfer the files that failed again, and manually delete the files that did transfer from my phone both new or old phones. I successfully transfer blocks of 250 photos at a time, although this takes a while as I transfer over 7000 photos monthly. I hope that the figures and information helps to decide if this product will suit your needs. Thank you for reading my review.

Theyre also a slim profile avoiding issues where theres limited space on busy USB ports on desktops and hubs. The build quality is good, they come in different colours, theyre FAST, well priced and reliable.I did have one concern though initially the body is most part made from metal and when is heavy use they get extremely hot. That hot its difficult to handle and a bit of a shock if you forget the temperature and eject them from the machine by the metal surfaces. I have used the Ubuntu disk for extended sessions of 8 hours Ive never noticed a decline in performance or any disfigurement of the drive itself. I have had drives that get hot before not to this level but theyre usually housed in a plastic shell. I can only assume that a. its a design flaw b. its an integral part of the design to disperse the heat generated.Ive been using these for a couple of months now, so its not something I worry about but just be aware that they get rather hot.Ive run some performance tests which you can view in the attached video, and theyre detailed below for both USB 3.0 USB 2.0Tests USB Deview, a small utility for managing USB devices with a feature to execute speed test for both read write.

This was easy to install, it doesnt require additional power and has provided me with a solid set of 4 additional USB 3.0 ports. I tested it to see if it would power some of my more power hungry devices which was flawless. This is impressive considering the PCI card did not require and additional power from the PSU. These ports were used during testing too.Ideapro 4Port PCIE to USB 3.0 PCI Express Expansion Card

I bought 2 of these drives to use as utilities because of their small size. I intended to use one for formatting hard drives and the other for installing Windows. On 2 different computers the same problem cropped up with both of these drives during Windows installations. Files were missing from the flash drives needed to install Windows. And Windows interrupted and halted the install, which means having to start all over from scratch with the install. It happened at different points. One time at 1 complete, another time at 83 complete still another time at 91 complete with no blue screen error. This is how I knew there was something wrong with the software on the flash drive.Being knowledgeable as I am I soon realized it was the SANDISK drives that were causing the ... MoreI bought 2 of these drives to use as utilities because of their small size.

This is how I knew there was something wrong with the software on the flash drive.Being knowledgeable as I am I soon realized it was the SANDISK drives that were causing the problem. For reasons built into the drive they dont copy all the files being transferred to them. It is kind of like a speed of date transfer over integrity of data transferred type of situation. Imagine how this affects a Windows installation after one has already erased their hard drive.So I tried another flash drive I had lying around with Windows 10 installation files on it and it installed Windows on both computers the first time. I therefore now do not recommend Sandisk USB flash drive products. Once it stopped working, anybody else not as knowledgeable as me in this situation, could have wound up replacing their computer thinking there was something wrong with it without knowing the problems stem from this inexpensive but deadly Sandisk flash drive.I rarely if ever give a bad review, but the situation above caused me such a panic at first that I feel obligated to share my experience.Because this happened consistently with 2 separate Sandisk 16GB Ultra Flair 3.0 flash drives, I am 100 convinced thedr drives are not as good as others. No fault of B H Audio.The drives I used to install Windows that did work I also bought from B H a while back so it is the Sandisk that is not suited for Windows installs. Thats my review.

I was not expecting too much from this and I was not disappointed in my expectations.The images show this flash drive formatted as FAT32 with default allocation unit size, NTFS and exFat formatting resulted in much poorer results, in particular the write speed which was about 110 of the Fat32 write speed.

That is twice the size too. The forth image is a Sandisk Extreme Go 64GB flash drive, NTFS formatted which cost me 26 about 7 months back, they are now only 17.99 on Amazon. It is much faster but the Ntfs formatting is slowing it down because it is meant to have 150MBs write speeds and Ntfs does seem to really slow down write speeds.Overall this drive is okay if your hard up, providing you do not do much writing to it. Some of the other benchmarks do suggest that the speed is very variable and my results come in lower than the stated speeds 130MBs. It might be okay to use as a Windows install flash drive because it does offer fairly quick read speeds and requiring a limited amount of writes. I would still use an Extreme Go flash drive.

Sandisk Ultra Flair USB 3.0 Flash Drive (128GB, SDCZ73-128G-G46)
22 October 2020

This little flash drive is a speed demon on a USB 3.0 bus...and of course its backward compatible with USB 1.0 and 2.0. Its tiny, and unlike many other flash drives, its slim profile enables it to fit easily into the USB port on Apples most recent extended keyboard without interference from the underside of the keyboard plate. Some flash drives are just too fat to fit there. And its sufficiently narrow that it wont interfere with other items plugged into adjacent ports on MacBook Pro models that actually have ports...you know, the ones Apple made before they stopped caring about user convenience. Actually, I have only two gripes with this Ultra Flair USB 3.0 Flash Drive 1. It has no cover to protect the connector. I dont mind the fact that it doesnt have a builtin ... MoreThis little flash drive is a speed demon on a USB 3.0 bus...and of course its backward compatible with USB 1.0 and 2.0.

Actually, I have only two gripes with this Ultra Flair USB 3.0 Flash Drive 1. It has no cover to protect the connector. I dont mind the fact that it doesnt have a builtin cover that would just make it fatter when its plugged in...not necessarily a good thing. But SanDisk should have at least provided a slipon plastic cover to protect the connector when the device isnt in use. I keep mine in a small plastic medication bottle to protect it. 2. The device gets very hot...I mean VERY hot, which makes it unacceptable for use in any application that requires the flash drive to remain plugged in for long. Thats not a good thing high temperatures reduce the lifespan of all electronic components, and I suspect that this little flash drive wouldnt last very long if I left it plugged in. Fortunately, I only use it for transferring files, and its so fast I never have to leave it plugged in for very long. One star off for the gripes, but otherwise its worth what I paid for it. If all you need is a file transfer device that doesnt stay plugged in for long, this does the job.

Sandisk Ultra Flair USB 3.0 Flash Drive (128GB, SDCZ73-128G-G46)
28 July 2021

I formatted the stick as FAT32 to plug in the car. However, the second time I did this, the format program responded with an error. From that time on, only a couple of programs recognise that the USB exists even the NAS linux based doesnt recognise it now. Windows finds it and that would be OK if I were only using it on windows but the car wont recognise it. Ive tried reformatting in different formats and back to FAT32, different format programs all to no avail. So now I have 128G stick thats useless for what I purchased it for at least if it had of been a card, I might have got away with it in the camera. Ive never had issues with other brands before, so I wouldnt recommend this particular Sandisk USB. In fact, I dont think Ill buy another Sandisk product again.
