SanDisk 256GB Ultra Fit USB 3.1 Flash Drive - SDCZ430-256G-G46, Black

This is a great flash drive to use as a Time Machine back up for your MacBook. I have a MacBook Air M2 512G laptop. This works great to back up using Time Machine. It is so small I can just keep it plugged into my laptop. And just eject it if it needs to be removed. It is very small with a little loop on top to place on a small key ring or something else to connect it to so you dont lose it. Even with my C to USB A adaptor it is a small device. See photos

The SanDisk 256GB Ultra Fit USB 3.1 is an excellent choice for anyone looking for a compact and high-capacity USB drive. I have been using this drive for several months now, and I am very impressed with its performance and reliability. One of the things that I really like about this drive is its size. It is incredibly small and compact, which makes it very easy to carry around with me wherever I go. Despite its small size, it has an impressive capacity of 256GB, which is more than enough for my needs. The drive also has a USB 3.1 interface, which provides fast transfer speeds. I have been able to transfer large files such as videos and photos in just a matter of seconds, which is very convenient. In terms of build quality, the SanDisk 256GB Ultra Fit USB 3.1 feels very sturdy and well-made. The drive has a metal casing that gives it a premium look and feel. I have accidentally dropped the drive a few times, but it has held up very well and has not suffered any damage. Another great feature of this drive is its compatibility with a wide range of devices. I have used it with my laptop, desktop, and even my smart TV, and it has worked perfectly with all of them. Overall, I am very happy with my purchase of the SanDisk 256GB Ultra Fit USB 3.1. It is an excellent choice for anyone looking for a high-capacity, reliable, and compact USB drive. I would highly recommend this drive to anyone in the market for a new USB drive.

Its seems pretty good other than it wont work for the primary reason I bought it. I purchased the 512gb version for a MCU2 Tesla to store video from the dashcam and sentry systems. Unfortunately the information system will not recognize it even after trying multiple formats and other troubleshooting. I got a micro SD in an adapter to work fine, but not this USB drive. Seems to work great in my Linux and Windows based computers, just but the Linux system in the Tesla.

Good for travel and extra hard drive space.

Funciona a la perfeccion, lo utilizo para almacenar mis archivos

Dead on arrival. Tried the flash drive on 3 different computers and not one would recognize it. Will exchange and may change rating depending on how the next drive functions. Update: Received a new flash drive in 2 days. The drive is advertised at 512 GB but you only get to utilize 460 GB. The flash drive seems to function well so far for the first few hours of backing up files.

Purchased 9 months ago. Pulled from USB port on laptop today and discovered part of the plastic connector had broken off and is currently stuck inside the laptop, making the port inoperable. Did nothing to stress or create the failure. It just broke because of the cheap plastic construction that SanDisk used for this product. I have been buying SanDisk USB drives for many, many years. This UltraFit was the first that had all plastic construction, including the connector which is typically metal. I was concerned but assumed SanDisk knew what they were doing. Wrong. As I prepared to write this review, glanced at customer photos and see that my problem is not unique. There are multiple users who have had the same problem. SanDisk should recall this product. This product is a mistake. Good news / bad news - Contacted SanDisk and they responded promptly, providing an RMA and prepaid label to return the USB drive. Bad news - they will be replacing with another plastic USB drive so wonder how long it will last. This product should be recalled. Funny thing, I usually do not post images or clips with reviews but had one in order to complete the RMA request process for SanDisk. I was going to post the image but Amazon is not allowing any attachments within reviews for the product??? UPDATE 5/12/20 Recd replacement 256GB from SanDisk support, about a 3 week cycle after starting RMA process. Replacement is same all plastic construction as original. Expected that but now scrutinizing closely and realize what a bad product this is. Began reloading backup files and noticed file transfer seemed exceedingly slow. I was loading a 25GB folder of large media files averaging 600 - 800MB each. Watching Windows Explorer real time performance graph, there developed a cycle of rapid writes lasting 10 - 15 sec, perhaps 700-800MB, which was then followed by a complete halt for perhaps a minute or more. Believe this is the result of protective circuitry within the drive that monitors heat, perhaps a safeguard required by the cheap plastic construction. The continuous writes of these long files heats up the SanDisk drive (which does get hot), the SanDisk drive shuts itself down for a minute or so to cool. After cooling off, the SanDisk starts writing again for 10-15 seconds and then shuts down again, repeating the cycle until finally completed. Wondering how much of the heat retention is due to the solid plastic construction and perhaps needed to prevent a meltdown. Out of curiosity, performed the same file transfer to a Samsung Fit Plus 256GB USB drive (Samsungs offering for compact USB drive). The Samsung completed the same task in a relatively brisk 8.5 minutes. I repeated the same test again with the SanDisk using same files and USB port as the Samsung. The SanDisk required almost 37 minutes to complete the same task...4 times longer / slower. The Samsung costs a few dollars more and clearly worth it. In conclusion, stand by my earlier recommendation that SanDisk should recall this product. See that they have just released a 512GB version, same all plastic construction, which I feel is an outrage. Combine the cheap construction and miserable performance, these Ultra Fit drives are JUNK, an accident waiting to happen. I am so disappointed in SanDisk that they would offer such a bad and unreliable product. UPDATE 5/13/20 More I fool around with this drive, the more angry that I get. Angry for the inconvenience but probably more disappointed with SanDisk, felt they were a better company than this. Aside from the flimsy construction which may save them a few pennys in manufacturing, the drives are completely unsuitable for any reasonable use. If all you want to do is transfer some small files and light use, it may be OK. But, if that is the expected use, then why get a large capacity drive? The whole point of owning 256GB of storage is to move around large amounts of data but these drives do not appear able to operate for even minimal periods of sustained activity without overheating. And then there is the issue of the cheap construction. Reading thru some of the other reviews, there are several commenting about how the drives lock up and unable use after that. I am guessing that the user sees no activity, thinks the computer is locked up and removes the drive. Believe the removal leads to corruption of the files. My experience says, be patient, allow the drive to limp its way thru. What is likely happening is that the drive has shut itself down momentarily due to heat. As stated above, mine started out seemingly great but after about 2 or 3 minutes of continuous writing, it started a cycle of randomly stopping and eventually resuming the copy task. After several more minutes of this, it settled into a pattern of writing data for 12-15 seconds, around 700-800MB and then pausing for 60-80 seconds before resuming, again writing 700-800MB in 12-15 seconds before stopping for another 60-80 seconds. The drive was hot so it appears the drives have heat monitoring and suspend operation until the drive cools down some. Making the drive useless for moving large amounts of data. Simple Truth - SANDISK IS SELLING JUNK NOW. UPDATE 6/21/20 - Recd the replacement of the replacement. Took about 3 weeks again to get replaced. Same lame performance documented above so must be part of the SanDisk design. Regret buying the 256GB Ultra Fit drive. If you have the option, buy the Samsung version and avoid this like the plague. A truly bad product.

I love the size. It is quite tiny and can be hidden almost anywhere. For securing information this is the optimal size.

This is my second time buying the disk on key 512 GB by SanDisk. The product arrives with about 50 GB less they are occupied for system files and background stuff. I noticed while transferring photos and videos that it is pretty slow lower to be precise slower than I expected it to be after running a few tests. I found out that my discount keys are running slower than advertised on the package and in the description. Overall I am going to be using these due to the fact that they still have a decent amount of storage for my usage and their size which is the biggest perk in my opinion.

Purchased two of these 512GB Ultra Fit USB 3.1 Flash Drive. Unpackaged both USB Drives and added them to my laptop. BOTH DRIVE SPACE ONLY = 460GB each!!!! << NOT EVEN CLOSE >> NO ADDED SOFTWARE ->> >>> 52GB SHORT per-USB Drive. -- TOTAL LOST Drive space = 104GB. You need to do better SanDisk!
