Speed side i noticed a debit 260MB read and 160MB / write 165Mo which is far from the 240MB specified on the product, however, we must put these figures, this is simply the fastest key (by far) in my possession (rather used to the Corsair brand). To take advantage of this performance it will of course you USB3 compatible equipment!
I'm booked on the retractable USB port system and aging over time, even if he is too early for me to pass judgment on this point, jy return in a while.
The key is of course formatted in FAT32 which will limit to 4GB files to overcome this constraint you will need to format it to NTFS without losing in mind sil are many products still on walking nacceptant that the FAT 32 so if your files are less than 4GB it is not necessarily required to format NTFS (up to you depending on your needs).
Delivered with encryption software PC data you will need to download for product owners apple OSX at this address:

I have not used this software, USB support on applicant does any important files.
To: the writing and reading speed, encryption software.
Against: the length of the key (we must store 128 GB) to see the aging system retractable USB port, the price (the speed may be at this price).
Conclusion: This key is really faster than i had in my possession it gives the impression of working on a SSD it is really extremely pleasant daily, depending on your requirements and files you'll have to transfer you can format it to NTFS (to see when buying), I will return to the retractable system in some time to keep you informed about its reliability.
