The Predator 512GB USB3 Drive is a unique product right now, being the largest USB stick you can really buy at the moment, but just as importantly, it is very fast as well for a USB drive. It's no SSD, BUT, as removable storage goes, it's very fast, outpacing my external mechanical hard drives and high-end SDXC cards by a fair margin.
And this is what I need it for, LOTS of FAST external storage all in one place.
Crystal DiskMark results, posted below, show this is about twice as fast in large file operations as my SandDisk Extreme SDXC 45 MBps card in my laptops built-in SD card slot, and about 3X as fast as my WD Passport 1TB connected via USB 3. Net, my go to portable storage device at this moment.
+Very fast for removable storage
+Rugged
+Secure and convenient key ring holder with quick release
+Protects the USB connection well via sliding mechanism without using an all to easy to loose cap
+Big-ish for a USB thumb drive, but small for something that holds 512GB!
-Performance drops off for 512mb writes
-No hardware encryption, must rely on a software solution
Highly recommended, but do wish for the hardware encryption option and can't wait for the 1TB version to come out!

---------Aug. 3rd, 2013 Update 512GB mSATA alternative delivers size and speed but not simplicity for ~65% of cost ----------
Thought I'd look into the possibility of using a 512 GB mSATA drive with USB3 case as an alternative. So, combined the Samsung MTD5120 mSATA drive from provantage with a mSATA USB3 case MyDigitalSSD Bullet Proof USB 3.0 mSATA SSD Enclosure Adapter MDMS-BP-USB3, connected through the best USB3 Express card adapter I've found to date, the Transcend USB 3.0 Express Card Adapter for Laptop TS-PNU3. Total cost was about four hundred fifty, so about 65% of the Kingston HyperX. Speed is good, size is small, but downside is having to have a USB3 power cable and adapter to use it. Net, for price I'm glad I got it, but given the need to have the USB3 parts all the time, I'll use this new mSATA setup in something a bit less critical with less frequent use, i.e., as a mobile backup for the MyDocs folder on my laptop when traveling.
Have posted the Crystal Diskmark results for the mSATA drive below, connected via USB 3 to the same laptop as my HyperX, so therefore, should be pretty comparable results. Note that the large file sequential read/write are deficient vs. the HyperX, while the random large file write and small file results are better. Net, usable, comparable speed.
