received one day earlier than the scheduled day, I admired the beauty of this key where I had hesitation to open the package so the key was beautiful in it! Once unpacked, I admit that the key is a sublime view. she is very big hand and can not be used on nearby ports when it is one above the other the risk of twisting the key. side perf: - Reading: 228mo / s is a little less announced - Writing: 158mo / s where it is much better contrast but for my case, no used, it is 99% that I would use reading - Small 4k files 9.219mo QD32 reading / writing 0.976mo s / s which is pretty good when you see the other hdd, ssd, drives, memory cards on mini files. it is the data in CrystalDiskMark 1000mb 3 passes scan. in practice, I copied over the files of several megabytes and above txt file folders and .dll under 4KB and I admit I was surprised how quickly to copy these tiny files (there were for all 2.97go by meme!) largely exceeding the flow rate announced by crystal because I saw for this folder there (just copy this mini file folder), announced win7 a copy 4.9mo / s constant to the key. the key is not heating or very little, even after playing big 15GB file. It seems both a beefy appearance (by the protective rubber) and low range (plastic) but after the reviews, it is powerful and enduring. only negative point I hesitate to put 1 star less: the cap. it is easily removed when it already protects the harbor, but to fix it in the back of the key, where ca is useless, it does not hold at all. AC will therefore like my corsair, the cap will eventually be lost in time ... for better compatibility let fat32. but if large files over 4GB you do not want / can cut out, format the ntfs. otherwise Alternatively, make 2 partitions, one fat32 and ntfs a.
