I'm not sure how I can give this any less than 5 stars. Maybe some could complain of price, but it is a great value for what you get. I am an IT professional, so security is paramount on the personal side as well. On the security side, this has military grade encryption and will destroy itself if the wrong password is entered a specified amount of times, but also if someone tries to physically break into it. It will also lock itself after a period of inactivity, so even if you don't have a screen lock, it protects you there.On the physical side, it is heavy which I actually like and built out of metal, so dropping it is not an issue. It can attach to a keyring, which may have saved me on an issue that I am about to tell you about, but I found it too big and cumbersome to attach it to my keys; I just did not like it in my pocket and when driving. It handles the test of time well and for years it looked very nice per the brushed finish. Certainly better than the D600 I replaced it with, where I noticed scratches on the edges immediately.Durability is also where the value is here. I have accidentally washed it multiple times through the years, following up with a nice thorough drying cycle in my dryer, then finding it later. This thing is a tank, which is nice when you consider having some very important files on there. I don't know it's water resistance rating, but it is sealed, and the fact it made it through multiple washer and dryer cycles means it is good enough.Times are not always good however. In December I was leaving work and checked for my drive on the way home. It was not in my pocket and I had literally just used it at work a few moments before and was sure I put it in my pocket. I turned around, franticly searched my office and car; nothing. I then realized it probably accidently fell out in the parking lot when I grabbed my keys out of the same pocket. Problem was, we were having a big snow storm. Once I realized it likely fell out, I went to the parking lot and irritatingly saw our facilities staff right on top of the snow, plowing the lot. I looked, but nothing. Asked the facilities staff to keep an eye out, but at that point cut my losses and since I did not anticipate finding it, replaced it with a D600 (which I don't like as much per less durability and not as secure). Fast forward to today, I was talking with a facilities guy who asked me about the drive. I told him I had been checking in the last couple weeks as the snow melts. I asked him the direction he plowed, and he told me, so I said I would have to check that location he piles the snow because I am not seeing it in the area I normally park, also complaining to him again at the efficiency they had in plowing... Oddly enough, 10 minutes later he comes into my office and hands me the drive. Sure enough, I pop it in and it still works.Interesting because when I lost this, I had some highly confidential personal financial information on the drive. I had just backed it up days earlier, so was not worried about losing data. My only concern was someone getting a hold of the drive and getting my data. However, there is a reason this drive is more expensive than other drives and security is at the top of the list. Even those others that are password protected can still be hacked or compromised physically, where these cannot. It was nice to know that my data was protected and even if someone found it, there was almost no chance anyone would get in unless they were interested in spending thousands of dollars to do it. Even then, good luck...In the end I am oddly no so surprised this still works, but it is amazing when you think about being pushed by a snow plow, being out in sub zero conditions, thawing period, rain and other elements, looks the way it did when found and actually still works. It is ugly now, but pretty darn amazing.So, if you are looking for a drive that is bulletproof, almost literally, and will secure your data to the point knowing any stranger can find it yet you still sleep like a baby at night, it is worth every penny. For the type of files I have on here, no other drive will do. Again, even those other drives having a password is just not good enough in today's day and age. Durability is key as well, knowing your data is intact after you do dumb things like through it in a washing machine multiple times, or drop it in a parking lot.
