Have tried in the past to utilize USB keys to transport confidential data with various encryption methods. The easier methods required admin rights on the host computers. The IT people at one of the hospitals have made the software impossible to use. The PADLOCK has bypassed this problem very well and with great improvement in read/write speed. Very easy to use and in a form which is convenient to carry. Nicely constructed. Would recommend for physicians where data confidentiality is imperative.

This drive does work like it says: strong encryption (128 is enough), well-built, and fairly easy to use.

Here are the comments that buyers should consider: the drive does not include an owner's manual, which is weird because one exists--I found it online at the company website. It includes a single-sheet instruction for setting passwords. I had no problem doing this, but then became baffled when I was done using the drive and wanted to re-lock it. It seems nobody had bothered to demonstrate this...not the instruction sheet, not the youtube product videos, not even the manual. They go as far as showing you how to unlock and use the drive, but leave it to the user to figure out the rest. There isn't a "lock" button, for example. You have to eject the drive (using the clumsy "eject secure drive" function in Windows, or drag-and-eject in Mac), and then physically unplug the drive USB. when you re-plug it, it's locked (and my Mac responds to the drive every time with the "unrecognized hardware: initialize, eject, or ignore" popup). You could simply eject the drive and leave it physically plugged, too, but again--nobody tells you this. You have to figure it out for yourself.

The drive is moderately fast, but not blazing. It doesn't feel flimsy, and the buttons seem well-constructed (I was worried they'd be cheap and might make drive use clumsy, but they're not).

Size: 500 GB (256-bit) Verified Purchase
I bought one of these less than a year ago and suddenly it quit accepting my user password and the admin password. Same passwords that had been on the device since I first set it up. As a result I lost everything that had not been backed up. With the reliability of disks these days, I am not too conscientious about doing backups so that was quite a bit of data. Usually you have to worry about a disk going bad, but with the Padlock you also get to worry about the Padlock firmware malfunctioning too. Support could not help, and the only recourse was to reset and reformat it.
Bottom line: Be aware that all the data on the Padlock could become inaccessible at any time. I was able to reset it and it is usable again now, but I lost everything that was on it. I will never be able to trust it again.

I was impressed with this hard drive at first by after 3 weeks the access code wouldn't work because of a product malfunction. Contacted the manufacturer who admitted they have had this same problem in other units. Nothing can be done to access the data. Lost everything! They offered to replace it but I told them forget it, too late now I lost everything I had on it which was quite considerable. I would never buy another one.

I prefer the Apricon series of portable hard drives because they are lighter and smaller than the competition, and always work with USB power only. The Apricorn Padlock drive is a great addition to collection, because it provides very easy to use protection against someone stealing my data if the drive is lost while traveling. The built-in hardware encryption is a snap to use, and does not slow down data transfer, at least as far as I have been able to determine.

Faster than the BlackArmor I used previously, and more easily portable, since it requires no driver or other software installation. I like the option to have a really long passcode (up to 16 digits), and the way it deals with the possibility of brute force attacks is well worked out. Reviews, here, that complain about the documentation seem odd to me; the drive comes with sufficient printed documentation to get it running, and there's a PDF saved on the disk that provides clear additional instructions.

You have the option to create multiple passwords for different users, so that if you later decide to remove one person (e.g. if an employee leaves a company), you can eliminate that one password while retaining the rest.

The soft case is nice (same as on Apricorn non-encrypted drives). The passcode-entry buttons feel robust, which is just as well, since you're screwed if you can't enter your code. I dropped my drive on the floor and it continued to work.

Price is right, and the device satisfies all my criteria. I bought two, so that I can keep them in separate locations in case of fire or theft.

No utility software is included (such as incremental backup software), but that's fine by me, as I'd rather do it my way.

This is an expensive external storage device but if you want to protect your stored files it would be well worth it, if it were reliable. Mine stopped working a few months after purchase, the device failed to recognize the password. Apricorn replaced it, but the same thing happened with the replacement after a few more months. Customer service is quick to respond, but they could not come with with solutions other than replacements.
