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

Love the tiny form factor, works perfectly, the small formfactor reduces chance of breakage because of sticking out like a pinky like other standard size ones.

Big storage on a tiny drive. I immediately bought a strap in the hope that it will keep me from losing it. Best use might be additional (backup) storage permanently installed in your computer.

Plug it to my laptop and never worry about accidentally breaking it since its so tiny. Have been using it for months and no issue at all. Very robust.

Excellent capacity and performance and from a brand that I trust at a good price.

Size is nice and compact but security software is funky and outdated right out of the box so must download the new version from their site and must be installed properly to function - there is no instructions on this except a few YouTube videos floating around - then update puts a bunch of random garbage files all over after updating- security will only allow privacy but others can still access the vault that holds the folders and delete the whole vault so it just seems silly - I work with photos and I would not suggest using the security vault for photos unless you plan on just storing them on there and moving somewhere else to work with later - the “vault” only allows for image information file names to view and not “thumbnail” image views so unless all your photos are labeled so you know what they are you are not going to like this for scanning over images quickly - it does have thumbnail options for viewing outside of the security vault so if you don’t care about keeping you pictures private then it’s probably ok but definitely wasn’t what I was looking for - also, it will only allow for file transfers up to 4Gb in size - anything larger than that and it will tell you it’s out of memory - took me a while to figure out why my 256 Gb drive couldn’t handle a 7gb movie until I researched it - the size is nice and small, almost too small to the point I think I will just lose it if I drop it in the grass - so in the end you’re better off buying a larger portable HD if you want total security and larger file transfers but ok if you just need a simple storage drive with bad security

As advertised. Good quality!

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.

Capacity is great. Small profile is great. That claimed 130MB is read speed. Please note... write speeds state UP TO 15X over USB 2 speeds. Key words here are UP TO. I use this device to store flac music files for playback in my car. I have plugged this drive into USB 2, 3 & 3.1 ports for writing purposes. I have seen extremely marginal performance differences between USB 3 & 3.1 (fluctuates between 35 - 55 MB when writing anywhere from 200MB - 2GB at a time). On a USB 2 port I get speeds around 20 MB on average. I will post test results and adjust figures as needed later as I am going from memory at this point. On another point, the frame of this no longer appears to be made of metal. I would say it is made of some type of composite material. I believe this was done with a purpose on the manufacturer to alleviate the heat issues with the previous model (which I also own) While it still gets warm while writing, it no longer gets hot to the touch like the previous model did. The heat dissipates much quicker. Given that, I do worry about the longevity and duability of this device should it have to be used and plugged in frequently in many devices. Overall, it serves my purposes. Write speeds could be better and durability could be an issue. Hence, my reason for three stars. **********Edit********** I have included Crystalmark tests (1 @ 500MB in size for USB 2 & 3). I did 5 tests while having it plugged into a USB 3.1 gen 2 port (1 of each @ 500MB, 1GB, 2GB, 4GB & 8GB). Speeds start dropping down the larger the test file was. Speed breakdown for the images is as follows for those that were wondering: USB 2.0 image is the read speed of 40.22 & write speed of 17.01 USB 3.0 image is the read speed of 126.2 & write speed of 50.41 USB 3.1 gen 2 images are the remaining 5 images as well as the windows copying images Just for a test, I copied over an approximately 4GB video file to the drive via the USB 3.1 gen 2 port (see the windows copying images). At the halfway point of the file, the speed starts to drop off and never recovers. Looks like the video file maintained a good 64 MB until the halfway mark.

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.
