Apricorn4TB Aegis Padlock DT 256-bit Encryption USB 3 Hard Drive (ADT-3PL256-4000)

Update July 2014:I have been using three of the 3TB drives for almost 2 years now on a daily basis. I'm very happy with their performance. In response to a couple other reviewers I've been using USB3 on these since I got them on multiple computers without trouble. I would estimate that I get approximately 80 Mb per second transfer speeds (well beyond USB2 speeds.) In regards to it not being compatible with Windows XP - it's also not compatible with DOS 3.1 (sarcasm intended). The only problems I have experienced are problems that we have with all hard drives -- a few sectors going bad - manageable via chkdsk. I intend to buy more of these in the future.Original Post Nov 2012:I have owned several Apricorn secured drives. They have always been easy to use and provide the highest level of security. This newest version has even more features. The most important thing to know is that the encryption security is done by the Apricorn electronics. Take the drive out and try to access the data - no chance. Additionally, because of the way they implement unlocking, the unit is protected from a brute force hack. Documentation is easy to understand (as easy as it can be). I could not be happier. I bought two so I could periodically backup the primary (all hard drives fail eventually) and am going to buy a third (for off-site backup).

I do professional court testimony as well as having a private practice. On my iPad I use PDF EXPERT so I can securely with encryption carry around my cases and testimony with me leaving the drive at home. The two complement each other perfectly and there is no need to use paper again or pay for the paper's destruction. Kudos. Given the sensitive nature and non replaceable nature of the material I am buying a second one to back up just in case as well as to keep in another location in case of fire or theft. If it is stolen I have no worries the data could be accessedI would like to see an initial "open code" that would then let you enter a second unlock code. In this way if the person got lucky with the open code they would have up to a max # of attempts like the iPhone before it is permanently locked up and info destroyed or never again be accessible. This would provide a valuable second line of safety that I think is needed but this is the other reason I am buying a second one. Either way I don't think anyone could ever break the encryption. All in all an excellent investment and I let the lawyers know, as well as my patients, how their information is protected. This eases their minds. I also do not connect my work computer to the Internet. My iPad is but once I'm done in court or at the office I erase the info on the iPad.All in all have no problems sleeping at night... I would highly recommend this item.

Use this for secure files and you don’t waste time with encryption software to run on the drive.

I bought mine on March 2016 and it was no longer working on 08/16. They did replace the unit .

Use these at work. Great devices, encrypted hardware so you don't have to deal with crappy software encryption.

I don't get it - I have one of these at work, supplied by my company, and I use it several times per week to back up my files securely; I have never had a single problem with it. So I thought I'd buy one for my personal use at home. It was nothing but trouble! One big difference is that at work, I use it manually by copying files to it. At home, I wanted to use it for automatic backups of my Windows system image, documents, etc. TIP - An encrypted hard drive that requires unlocking is NOT a good solution for that because you have to have it unlocked when the automatic backup kicks off - my bad on that one, wrong tool for the job.Another difference is that my work PC runs Windows 10; at home I'm still on Windows 7. POSSIBLY the issue below is due to Windows 7 not being able to recognize an 8 TB Drive...? Not sure.However, the reason I gave this a 1 out of 5 is a deeper issue and has two parts.1) After hooking the drive up and getting it ready, I unlocked it and ran a complete Windows Backup - that took almost ten hours (admittedly I'm running it over USB2, not USB3). It appeared to work fine, and when it was done I was able to see that the backup was indeed on the Aegis drive and was occupying about the right amount of space - about 500GB. So I locked the drive and left it alone for a few hours. Later, when I came back to it, it wouldn't unlock - when I entered my code, the green light just sat there blinking and the drive never showed up in Windows Explorer. I gave it a half hour, then called Aegis Tech "Support." The "Support" piece brings us to point 2.2) Aegis Tech "Support" sucks. Totally useless. The guy was so lazy.... I explained the issue and the most helpful thing he said was "that shouldn't be happening"... DUH!! Then he said the only option I had was to call the vendor and work it out with them - that could be Amazon. He never even mentioned the option I tried next...So I got out the manual and used it to guide me through resetting the drive to factory specs - very easy to do, by the way. I wiped the drive, put in the new code, got it all set up again, and tried another backup. It worked great, but then I couldn't unlock the drive again afterward. Same problem, in other words.I gave up - for $585 it should work more smoothly than that.HUGE KUDOS to Amazon - they issued a prompt refund upon my returning the device in its original packaging and the whole ordeal ended up costing me zero money and a few days of my time.Take-aways:If you want something for automatic backups, this ain't it.If you want competent tech support, Aegis is not the company to deal with.If you want a vendor that sticks by their products, Amazon has a stellar track record, at least with me.

Works great for storing tax files and such. I had to reboot the whole drive when new so I could download to it. Their tech support was very helpful

This is my second Apricorn product. Greater storage, more durable product design with all of the original features of encrypted external data storage.

Very Good!

Klappt prima. Schnelle Backups dank USB 3. Man fühlt sich sicher. Es scheinen Toshiba 6TB Platten verbaut zu sein. Beim Dauerbetrieb (>24 Stunden) wird das Gehäuse durchaus warm. Ich schätze mal so ca. 38-45 Grad Celsius.

Una lastima, porque necesitaba un producto como este, pero mi Windows 7 no lo reconoce y ante fallos asi, ni me la juego en tener mis datos ahi.

Hasta el momento ha funcionado muy bien, no me agrado mucho que las instrucciones son poco claras y escuetas pero cumple con los requerimientos de seguridad que yo buscaba. Un punto a favor fue lo rapido del envio, apenas tardo 4 dias

Very secure. Heavier than a brick haha but great unit.
