ADATA 64GB UV131 USB 3.0 Flash Drive (AUV131-64G-RGY)

Pros: Looks good. Runs fast and cool.

Cons: None

Overall Review: Bought three of these ADATA drives. Two 16's and a 64 GB. Installed a Linux MX-15 operating system on one of the 16GB drives. That is about as hard a workout as I can imagine using a stick drive for. Runs fast and never has heated up past just warm to touch. I carry it in one of those old plastic coin purses which were popular last century.

Pros: Very well constructed thumb drive. Transfer speeds are great! Love the metal case verses plastic. I haven't had an ADATA drive fail yet!

Cons: None

Overall Review: As long as ADATA keeps making solid thumb drives like this, it's all I'll be using.

Pros: Inexpensive. Metal body should withstand some abuse. Looks OK. Key ring.

Cons: I seem to max out at 15MB/s writes and 100MB/s reads. I didn't test it extensively, but large files on a few machines all had similar rates. Not the greatest speeds, but for the price, I'm not angry. Key ring shape is a little awkward. Key ring may be too small for some rings. Stick appears prone to water intrusion, with limited ability to dry out.

Overall Review: Bought two. One is on my key chain, the other is a spare. Pretty happy with the value.

Pros: Shiny, well built.

Cons: Very slow. I'm getting 36 MB/s read, and 24 MB/s write when copying a 2GB file in Windows 10. For the same file copy in the same USB 3.0 port, I'm getting 98MB/s read, 69MB/s write with a 64GB Lexar S75.

Overall Review: Stay away from this USB stick if you're looking for USB 3.0 speed!

Pros: inexpensive, capacious. To expect more performance or space for less money would be unreasonable. Crystal Disk Mark reports seq. read speeds at 130.4 MB/s and seq. write speeds at 26.89 MB/s

Cons: Write speeds are about one-third of other Adata flash drives.

Overall Review: Its amazing capacity, build quality and performance for this price point.

Pros: Faster than my old Cruzer 16Gb Titanium edition. No caps to loose or sliders to mess up. Smaller than I anticipated. No preloaded software.

Cons: Scratch marks do appear where the drive is plugged into USB ports. Two thin lines on each side of the plug portion of the casing.

Overall Review: Increasing the scratch resistance of the plug portion of the drive would make this a five-star review.

Pros: - I like that it's metal - It's not retractable and I find that those wiggly parts are always annoying - I got it for a decent price

Cons: - Collects fingerprints

Overall Review: I have three of these so I've just made a small, different colored sharpie mark on each one so I don't have to plug them all in to figure out which one I need. I haven't found any problems with these so far. They get warm when transferring files on a usb 3.0 port but that's just an observation.

Pros: Good price, nice speeds while it lasted.

Cons: Died within four months of purchase. After confirming the issue with a diagnostic tool from ADATA, received an RMA number to return the product for replacement. However, ADATA apparently has only a single RMA center (in California) serving both the US and Canada, and expects the buyer to bear the cost of shipping back to them, even across the border. Needless to say, as someone living in eastern Canada (having purchased from Newegg.ca), the cost of international shipping means that there's practically no value in RMAing the drive versus just giving up and buying a new one. I'd warn anyone away from this brand if my experience is at all representative. Marketing a product in Canada without providing RMA facilities within the country comes across as distinctly shady to me...

Overall Review: Don't expect the drive to stay shiny and fresh-looking for long, the metal finish smudged, scuffed, and tarnished quickly.
