SanDisk 128GB Ultra Fit USB 3.2 Gen 1 Flash Drive - Up to 400MB/s, Plug-and-Stay Design - SDCZ430-128G-GAM46, Black

I've been using the SanDisk Ultra Fit 128GB USB 3.1 Flash Drive for a few years now, and I’m thoroughly impressed with its performance and convenience. The drive's compact design is a standout feature—about the size of a wireless mouse receiver—which makes it incredibly discreet and perfect for leaving plugged into a laptop, car stereo, or smart TV without sticking out or getting in the way. Its sturdy build ensures it can handle daily use, and the plug-and-play capability means it worked instantly on both my Windows PC and LaptopThe transfer speeds are solid, averaging around 130 MB/s read speeds, thanks to USB 3.1, enabling quick movement of large files. The 128GB capacity offers plenty of space for documents, movies, and media backups, making it ideal for on-the-go storage needs.However, a couple of minor points to consider: during heavy use or large transfers, the drive can get warm, but it hasn't impacted its performance or durability. Also, because of its tiny size, it’s easy to misplace—adding a keychain loop or some form of attachment could be helpful. Despite that, it's a small trade-off for such a high-capacity, high-speed device.Overall, I highly recommend the SanDisk Ultra Fit for anyone seeking a reliable, portable, and fast USB drive. Just be mindful of its small size, and you'll have a fantastic storage companion at a great value

Micro sized 512 GB Flash drive is fast, secure, compatible with PC, Linux, Mac, Android. Small design is great for the laptop, looks so discreet. Easy to carry on keyring and take anywhere. GREAT PRICE! GREAT QUALITY! HIGHLY RECOMMEND!

This thing is so tiny and works so great. This can easily be mistaken for a computer mouse chip. I haven’t had a problem of files loading or downloading too slow. It is so convenient to add extra memory onto your device. I put this in my laptop to add extra memory without having to take it apart and adding memory inside. With its small size it still has great quality. This is a great option for adding extra memory without taking nearly any space compared to other flash drives.

Ridiculously fast and a great tiny size. I’m glad it was a multi pack as they disappear fast…

Great price for 512GB, but performance is really mediocre at best. Write performance does burst immediately to 120-140MB/s, then slows to a sustained 80MB/s. Anyone else testing this and posting faster write performance probably is testing incorrectly. I purchased this for a home lab server to dump VM backups to locally without having them be on the local drive or having to push them over the network. Seems to work fine, although not very fast. The compact nature of this is nice so it doesn't cause problems when working around the device. For the price, I'm happy, although I may have opt'd for something a bit faster if the write performance had been known.
