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

I will be making future purchases of this product.

Been downloading music and photos to this drive and so far its worked flawlessly. Although Ive only used about 10 gigs of music and pictures, Ive experienced none of the overheating issues others here have claimed. All I did was plug it in, create some new folders and I was off to the downloads! Great portable drive for backup storage, music, photos, just about anything you can store on you HD/SSD, you can do with this drive, and it fits in your pocket so easily.

Big capacity, small size. It does get a bit warm when used for a while

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!

Exactly what I wanted - its so small and has excellent capacity. I loaded up my entire music library and plugged it in to the dash of my car. Youd never know it was there. Only problem is, the fit is so snug, and the lip of the drive is so small, I cant grasp it to remove it! The lip is just a bit of plastic. Im afraid if I try to remove it with a tool Im going to crack it.

Small size that can remain connected to PC.

I dont know how many Ive bought now. I did crack one and lost all the data that was in it, hence the minus one star. I would be raving about it if it had been durable enough to withstand taking the brunt of the fall when my laptop slid off a low chair. I keep it inserted all the time. So when my laptop fell, the flash drive cracked from the pressure of being crushed between the floor and my laptop.

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.

SanDisk is generally my go to for flash drives & SD cards. So far they have not let me down. These drives are great to use in applications where you just want to plug it in & leave it there. They dont stick out to get in the way. I got one to load my music collection to use in my cars infotainment system. I just plugged it into the usb port & it stays there w/o getting in the way. Since then, I started using these for a few raspberry pis where I wanted bigger, more reliable storage you can boot from them ( you may need to flash a newer BIOS). If you are looking for a flash drive to carry around, Id either attach this to a key chain or something using the lanyard hole, or go with a physically larger drive. These are small enough that it could easily be lost w/o noticing

I use this device to store drum kits in my Yamaha DTX900 e-drum module. Im not sure if I will ever run out of storage. I have dozens of kits stored on one drive so far. Since it is so small, I leave it in the module.
