64GB USB Flash Drives Slim Thumb Mini Nano Micro Waterproof

I wanted this for a wallet-sized flash drive. It works fine for what it is, and is authentic and functional, if slow flash (~3MB/s write ~25-30MB/s read). I think this is about as well as one can do if you just want to be carrying a flash chip+minimal USB contacts around. This device enumerates as VID 346D / PID 5678 "USB Disk 2.0" with a generic vendor name field. Write speeds are typical of a device with a small SLC cache and slower underlying MLC storage (~3MB/s overall including occasional bursts to USB 2.0 speeds of 20-25MB/s and slowdowns to ~1MB/s). Read speeds are ~USB2 (28.6MB/s for a full-drive read). The drive is ~of the stated capacity with typical loss to overhead (58.59GiB=61.44GB, received as EXFAT and formatted as NTFS here). Tests with F3probe/F3write/F3read indicate it's all usable. Build quality seems fine for what it is - it's a small chip-on-board type device with the expected level of thermal solution (i.e., virtually none - there is no room for a heatsink given the size). Given the write speeds it doesn't heat up appreciably during operation. It's very slow flash relative to modern devices, but anything USB3+ would probably just throttle anyway in this application. I would prefer a name-brand device but I think this is probably the realistic limit for this type of minimal device and it probably can't be done much better.

use for a while - run fine . Not too high speed but size good

I am very pleased with this flash drive so far. It can be a bit slow sometimes to transfer files to it, but I got it more for durability and size anyways. If I wanted something high speed, I'd just get a portable SSD. I've had this drive for at least half a year. In that time, it has often been submerged, or gotten wet in not exactly clean water. Still seems to work fine to me. It does need to dry before being used as far as I can tell. I guess it was still a bit wet inside when I tried to use it once, and it didn't work. But when I tried again a few hours later, it worked fine again. I've kept it safe from impacts and other rough environmental factors besides water though, so I can't attest to its durability with those. I did run H2testw on it when receiving it, and the near full capacity is writeable and seems usable. There is some minor size discrepancy between the advertised space and what shows up on the computer, but that's expected for anyone familiar with storage drives. Physical size is probably as small as you can make a USB-A flash drive, so I'm satisfied with that. I spent a lot of time looking for and trying quite a few other things, before I found this product. I wish I found it sooner.

Be careful with this thing, it is tiny. But it CAN be formatted to fat 32 to work in older USB car stereos.

Excellent to store and play my music in my car !! My favorite Flash Drive !

Design is nice and low profile. I use my to boot my OS on mini pc as I am using sata and m.2 port to get max storage for home made nas

This flash drive is extremely slow; it takes a bit over 20 minutes to copy a 4.5GB ISO image to it. In contrast, a different (major-brand) flash drive I just tried takes 35 seconds, or about 34.3X faster. Edit: I noticed after posting this that the sales page claims 21mb/s. The above is only about one fifth that speed. I bought this for hiding an emergency-fund crypto stash while traveling. This can be fit under a large-sized bandaid. I installed a bootable Linux distribution on it (which took a loooooong time to write; so long that I thought the drive was defective) and it will boot up and run on my laptop, but anything that tries to write much data to this (e.g., swapping) is going to freeze.

Excellent and compact very fast transfers

Buono per qualità prezzo

Es muy pequeña, pasa desapercivida. Dejó de funcionar al mes, justo después de terminarse la ventana para devolución.
