Summary: I've used 3 other brands of USB drives & none 'cept this ADATA has crapped out on me like this.
Cons: 1st one died w/ in a month. Replacement died 1.5 mos later. Problem same for both:USB became incommunicado during a large file write. After that, drive wasn't recognized by WIN7's file explorer, nor did it appear in Disk Manager. Oddly, it appeared in Device Mgr,, but uninstalling, reinstalling, refreshing, uninstalling/reinstalling USB drivers didn't work,Tried on other PC's;same result. Would note buy this drive again. I've been a NewEgg Customer for 8 years, but no...
Summary: After having a very good experience with Adata's S102 Pro series (bought several of them) I decided to upgrade to this model. Like other reviewers have mentioned, I keeps asking for a re-format, it was bad out the box. It eventually stopped working all together and I lost the data on there, luckily i had a backup on my Passport. Also, sounding off other reviewers, it gets hot and feels like cheap plastic.
Summary: it's might be a defective product. Submitting RMA !
Pros: Slim Design
Cons: Large file copy (8GB), read/write performance starts off fine, but write performance starts degrading significantly and where it's staying while operation takes 60 sec and it takes 8-10 mins to do the job.
Summary: The product I received worked fine, the problem is the picture and description said it was a brushed aluminum surface, not true, the one I received was black and plastic. If the picture and description are wrong. please change it! People buy things based on this and to receive the wrong product, well just say I am very disappointed to say the least, no matter how well the product works.
Summary: Plastic keychain holder broke within a week. Slider broke a day or so later. Now I have the device super glued open, tie wraps as the keychain loops and all held together by electrical tape. Not any good if you plan on using it as an actual travel device. Metal sides just sandwich the cheap plastic in between. My hunt for a durable 64GB USB 3.0 stick continues.
