SanDisk 128GB 5-Pack Ultra Fit USB 3.2 Gen 1 Flash Drive (5x128GB) - Up to 400MB/s, Plug-and-Stay Design, Non-Retail Packaging - SDCZ430-128G-B5CTA

I bought it for my laptop, to cache my steam game content off of my hard drive.Pros: large drive, super small profile (so you don’t need to remove it) and reasonably good transfer rateCons: it worked well for games that didn’t require loading super high Content really quickly. But, when transitioning through medium to high quality “open world” style textures and content, It was a little laggy and I had too many lag deaths. This only happened on 1/4 of my games.So, my solution was to move the content back-and-forth from my hard drive to the removable drive for those games that require a little more speed on their transfer rate. A minor inconvenience, but on the whole, it has satisfied my ability to load 400 GB of games, and have them available on my gaming laptop.All in all good drive, maybe my expectations were too lofty.

They’re that good, one is currently in my old X-Box 360 making that thing run games blazing fast once again and the other has Linux Mint on it for my 10 year old MacBook Pro. High transfer speeds and super tiny, highly recommend.

I purchased the USB in February 2019 and it failed in Nov 2019, ten months hmmm. From new it required far more pressure to insert then my other USB drives and the housing became noticeably warm when in use. At that point, I should have sent it back but instead dismissed it as the consequence of its small architecture and poor manufacturing tolerances. After less than fifty applications the housing broke but more annoying the stored data became unrecoverable. I have several full size SanDisk and other maker USB drives and none have exhibited the above noted concerns or failures. Unfortunately four days ago my wife purchased the SanDisk 256 model and it also requires more insertion force than should be required, foreshadowing dear reader. Would I recommend this product? Absolutely not. Will I continue future Sandisk purchases? Probably, but not their miniature series. SanDisk, if you wish to offer me recompense, I will gladly include your response as an appendix to my review.Cheers EUpdate: Nov 25, 2019The day after submitting my Amazon review I contacted the SanDisk warranty department by email requesting recompense as the USB was less than 5 years old. I provided them a copy of my Amazon purchase order and the next day I received a follow-up email from SanDisk® Global Customer Care stating SanDisk did not have a 128gb replacement in stock (in the warehouse) but would I settle for two 64gb instead to which I replied, yes. Within a day or two I received another SanDisk email this time different in tone. It referenced my Amazon.com review and included the following highlighted in blue, "Note: Refurbished, physically damaged or non-authentic products are not covered by SanDisk warranty". The email also included an RMA (Return to Merchant Authorization) but no mention of the previous replacement offer.So what happened, a SanDisk employee armed with my Amazon purchase receipt trolled the Amazon.com website and located my review. Upon reading it they identified I had mentioned the USB casing had broken and presto SanDisk feels the warranty claim is disqualified, hence the blue highlighted script. To appear as a good corporate citizen they now offer me an RMA (Return to Manufacturer Authorization) so we can go through the process. Okay I will, with the clear understanding that I intend publish every SanDisk response regardless of the outcome.Other critical Amazon reviews about this product identify similar concerns, it runs hotter than a full sized USB, it is a tight fit especially in USB 3.0 ports, the housing cracks and this device prematurely ends in software/hardware failure. See a similar Amazon.com posted review provided by Gennaro M. on March 15, 2018. It is one of the many provided by dissatisfied consumers. My complaint, like those generated before me, does not originate from consumer misuse, abuse or accident but by product failure and warranty issues.Stay tuned for SanDisks response which I intend to publish when I receive it.Cheers EOn 2019.11.27, I received the following email from James P.. a SanDisk® Global Customer Care rep, "Thank you for writing back to us. Please be informed that the statement which was sent in the e-mail is a standard statement which we use in all automated RMA approval e-mail for letting customers know that Refurbished, physically damaged or non-authentic products are not covered by SanDisk warranty. Also we understand that you are not very satisfied with the model of flash drive which you were using earlier i.e. SanDisk® Ultra Fit USB 3.1. Therefore we would like to offer you an alternative product i.e. SanDisk® Cruzer Glide USB 3.0 128GB (SDCZ600-128G) in replacement. Please suggest if you are agreed for the alternative model".I agreed to accept their offer and on 2019.12.10 I received without cost to me a full size USB SanDisk® Cruzer Glide USB 3.0 128GB (SDCZ600-128G) delivered to my door. In the end SanDisk® or the parent company Western Digital Technologies Inc honored the warranty. I will continue to use SanDisk® as long as the honor they warranty. However I would not again purchase or recommend this specific product the SanDisk® Ultra Fit USB 3.1.cheers e.

Great Multipack. Doesn't come in retail packaging as described in the listing. Great if you require multiple Usbs. The computer had no issue finding the drive and they have the listed size. They will stick out of the usb so you can drop them but will work great in laptops on the go as they are small enough that they won't break off in the usb slot.

I use this to expand my storage on my laptops. I try not to store much on the laptop itself and store on these instead. 1TB is more than enough storage for me. I've used many different kids and this is the only one where my computer recognizes it every time. All the others had problems being recognized by my laptops. They would work when they wanted to. My laptop would say, don't recognize device. Or they would be there and then they completely disappear from the laptop. They would be plugged in but not seen by the computer. This is the only flash drive where I have zero problems with. Sometimes saving to this flash drive is really slow but so what. As long as it gets saved on it and I can access it whenever I want. It's reliable and that is all I'm looking for. Just plug it in and leave it there. Very small so you don't worry about it getting snagged on anything. Very secure in the USB slot. I bought 2 more of 32gb that I plugged into my Amazon TV Fire Cubes 3rd Gen for extra storage. Again, very secure in the USB port.

Perfect expansion for my aging laptop. It's sleek and barely noticable, but it holds so much info and it's easy to transfer between my laptop and my PC for transfer of files. Best peripheral purchase I've made in a long time!

The SanDisk 512GB Ultra Fit USB 3.2 Gen 1 Flash Drive is a compact and efficient storage solution. Its slim design allows it to fit snugly into a USB port without sticking out, making it perfect for laptops and desktops where space is at a premium.In terms of performance, the drive boasts impressive read speeds of up to 400MB/s, which is great for quickly accessing files. However, some users have reported slower write speeds, averaging around 10-15MB/s, which can be frustrating when transferring large files.The drive is also praised for its durability and reliability. Many users appreciate its ability to store a significant amount of data, including photos, videos, and music. It’s compatible with various operating systems,On the downside, the thin plastic construction might feel flimsy to some, and the small size can make it easy to misplace. Additionally, the lack of a protective cover means extra care is needed to prevent damage.The SanDisk 512GB Ultra Fit USB 3.2 Gen 1 Flash Drive is a solid choice for those needing a reliable and compact storage solution, though it may not be the fastest option for large file transfers.
