Bottom line: The Patriot Xporter XT Boost 16 GB is a good USB drive but far below the performance I expected. Its tests average slightly below a Class 8 flash drive or 50X.
I will update my review on the cap status in the future since most rubber caps loosen with age and this one is a pocket gripper. I may epoxy a little leash on it to the body.
Reading so many of these reviews does not help in purchase decisions. Frankly, they drive me nuts. "It was so fast!" "It was so much faster than my old drive!" "Some people are too scientific." "It booted immediately on my Windows... (version)/Mac [computer]." (Please do not take any of these comments as personal attacks on your reviews. I have been hammered in past professional writing to ensure I provide hard, substantive data for any statement I make.)
Can I please have objective data to assist in my purchase decision? The first thing I do is benchmark when I receive a flash drive or flash card. I have returned fakes, counterfeits, and below spec units. Formatting new drives appropriately upon receipt is a smart decision, since it removes any crapware from the manufacturer and any viruses a disgruntled employee could have placed. (Does anyone remember the WordPerfect employee who knew he was going to be fired back around 1990?) Although not a Mac user. I use flash drives for Windows Vista/7 and Linux OS purposes.
Flash "class" is based on write speed. I have included a conversion table toward the end of my review. I am sorry I forgot to specify sequential write testing for my benchmarks. To increase accuracy and reduce extraneous hardware reductions in test results, I do not use USB extension cables and clean format the flash for each test. Here are some hard data for you on the 16 GB Patriot XT Boost I received from Amazon:

Four sector errors in last block of flash, 2nd Pass: No errors (I did a second pass since the first showed physical errors and it could have been caused by factors outside of the flash, which it was.)

Thank you for reading my review. I hope it helps you. Please approve or disapprove so I know if I should continue writing and submitting results from this several hour process for future drive or card purchases.
