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.F3 probe:F3 probe 8.0Copyright (C) 2010 Digirati Internet LTDA.This is free software; see the source for copying conditions.WARNING: Probing normally takes from a few seconds to 15 minutes, butit can take longer.

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

(exFAT)Average Read (22.5 MB/s)Average Write (3.5 MB/s)for a usb 2.0, it works.Boots Linux, although slow to originally write to usb, once synced, everything reads fine.the format matters for how large of files you can transfer. FAT or ExFAT limits, and NTFS is better for larger files. I bought 2 of them.

Perfect size, good amount of storage. It only registers like 58 gigs. But still enough for it being smaller than a quarter. Thank you.

As others have stated, this thing is on the slower side compared to more modern, full-size options.The storage capacity is also nothing impressive by today's standards, either.But there's scarce little else out there with this form factor and price point.This is a USB drive with about the footprint of a microSD card.Some concessions have to be made and I can understand that.Functionality-wise, it's a USB drive. What more do you want? It stores files. Straightforward ease of use.Gave it a format and it worked like a champ.Did not get noticeably hot when putting a bootable OS on it, which was my use case for this product.All in all, I have no real complaints.

If you own a Ford that has the SYNC system and it no longer supports a MP3 Player then you might consider this as a great replacement if you have tons of MP3.

Recomiendo el producto es sumamente rapido me funciono para mi objetivo de memoria swap en Linux Ubuntu para un servidor.

I really like the size and form factor of the drive, however, the drive will not reliably allow me to copy files or stay mounted to the computer. I could copy one file, but copying a second would stall out. File sizes were about 20 MB-50 MB in size.I should also say I am on a Mac. The drive was originally formatted as ExFAT. I erased the partition with Disk Utility and tried other file systems (MSDOS, Mac OS Journaled), however, only ExFat would work with this drive. The drive would often eject randomly and I could not copy over more than a couple files the entire time I tried working with the drive.
