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

The capacity and speed are fine. Whats not good is the oh so thin plastic casing of the drive. Its cracked open and almost broken away. Not good Sandisk!

So far I have two of these flash drives. Both are currently connected to my laptop via a USB 3.0 hub. One is older than the other. Both have been functioning well. I have the 256 gb version on both. Nice amount of space for not a lot of money, helping me keep my hard drive cleaner. At one point I did have the older one directly connected to the computer. Ive not noticed any difference in the transfer rate since I swapped it to the hub, which was something I worried over. Both have nice transfer speeds, more than geared to my needs. *Edit, August 2021* Since I originally wrote this review sometime in 2020, I have invested in several more of these drives. I now have somewhere around 12 to 15 or so ranging in size between 64 gb all the way up to the 512 gb version. They are used in multiple applications. Three are TV drives, attached to the three smart TVs in the house (unless Im adding to them, in which case they spend some time in one of the two USB hubs I have.) One is about to be geared towards my Wii, and the rest are computer storage for my desktop and laptop. Those computer storage ones are the ones that live in the hubs full time. I use them for everything. Ive a massive music collection, and that is now split between about 4 of the 512 gbs. My movies are on another, one is for computer file storage (which is my catch-all drive for program files, pictures, and documents.) I could keep going with the uses I have for these, but the long story short is I no longer have to worry about losing everything if my hard drive fails me. Because even if one or two of these lock up, loss will be minimal. Speed is still not an issue at all, And to date, none have locked up on me, and they see quite a bit of use.

Good and easy to use.

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.

The product is good but the durability is bad as you can see in the photos the USB flash drive banded, easily. made with really thin plastic.

Very good addition to my backup tools.

Worked instantly out of the box. It wanted me to download some sketchy Mac software but it works perfectly without it.

Pros: 1. This drive has been very reliable, and Ive never had any problems with reading or writing data from it. 2. Its tiny! It could, in theory, be plugged into a laptop semi-permanently without much trouble. Cons: 1. The thing is made of cheap, flimsy plastic that looks like it would break if I ever tried to carry it around in my pocket. 2. Its super slow. Plan for USB 2.0 (or worse!) speeds. Other thoughts: Originally I got this for archival purposes, as 512GB flash storage was nothing to sneeze at in 2020. Earlier this year (2023) I switched to a much better archival system, and so nowadays I instead keep it plugged into my main rig as permanent storage, with recycle bin enabled. I basically use it in place of the Downloads folder, for all the stuff, both wanted and unwanted, that you accumulate browsing the internet, watching media, etc. This has allowed me to use my main SSD for more important files, and saved me the inconvenience of upgrading to something larger. So, its definitely nice to have. I wouldnt recommend it though, as there are much better options out there. Speed really does matter a lot.

I am amazed that I can load so much into such a small item-I will be buying more in the future

I can keep this little drive attached at all times and not accidentally karate-chop it off like I have with drives that stick out two inches. Adds an instant 500G to my computer inexpensively.
