Description

Looking for an effortless way to secure your data while taking advantage of the fastest USB 3.0 speeds? Look no further than the Aegis Padlock 3.0. Featuring your choice of AES-XTS 128-bit or 256-bit hardware encryption the Aegis Padlock 3.0 seamlessly encrypts all data on the drive in real-time, keeping your data safe even if the hard drive is removed from its enclosure. With a super speed USB 3.0 interface, you can now access your files faster than ever before. The Aegis Padlock 3.0 is also backwards compatible with USB 2.0 and 1.1 ports. With no software installation required for setup or operation and the ability to run on any platform, the Aegis Padlock 3.0 provides stress free deployment in corporate environments. The Aegis Padlock 3.0 also employs a useful drive reset feature, which can be implemented with a unique command. This clears all PINs and data, and creates a new randomly generated encryption key, enabling the drive to be reset and redeployed as many times as needed. In addition to encrypting all of the PINs, data and the encryption key itself, the Aegis Padlock adds another barrier between a between your data and a hacker. The encryption chip and circuitry of the Aegis Padlock are completely protected by a super tough epoxy compound, which is virtually impossible to remove without damaging the drive.

Trusted Brand, Solid Performance, and Easy Setup
Capacity: 2 TB Style: Drive Pattern: Padlock
This is a solid product from a great company. I’ve dealt directly with them before, and they stand behind their products. I own several of their devices, and they’ve all been reliable. This drive is a good size and easy to configure. I do recommend reading through all the setup steps first, then going back and following them as you go, since some steps are timed. The drive has a convenient spot to store the USB 3.0 cable and comes with a nice carry case. It also includes an extra cable that isn’t clearly labeled—this is for providing additional power if you’re using an older computer or a low-power USB hub. I haven’t needed to use it, even across multiple computers. Transfer speeds have been good, and overall performance has been very solid. If you need portable hardware-encrypted storage, this is definitely a great option. The company also offers other secure solutions if you need more features. Highly recommended. ... show more

Easy to use secure storage for client files - Customer support also very helpful!
Capacity: 2 TB Style: Drive Pattern: Padlock
I work with many confidential clients (lawyers, doctors, etc.) and when working on their computers I need a secure way to temporarily store their files. Being HIPAA compliant, I need to be certain that my clients' files are not accessible by anyone else. This fits the bill perfectly. It works fine, and had enough room to deal with several clients at one time. I did have one initial problem... the drive kept locking every 30 seconds (Windows 11) until I put it into lock override mode. I sent support an email and they responded within 24 hours with a registry fix, which solved the problem immediately. Five stars for customer support! ... show more

Convenient Piece of Mind
Capacity: 2 TB Style: Drive Pattern: Padlock
I had used several Apricorn Aegis a drives at work and decided to try one for personal use. Case is tough and doesn't feel like it will be damaged easily. Transfer speeds are good given it is a HDD inside. The cable could be longer but it is nice to be able to snap it into place around the device and not carry a separate cable if you don't want to. The one thing I usually have to do on most modern computers I have used it on is to adjust the power saving settings on the USB port it is plugged into. More often than not the power port would enter low power mode during a multi-hour transfer which would trip the auto-lock on the drive. While a nice security feature, and how it should be as it thinks you removed the drive, it could be frustrating to come back several hours later thinking the transfer should be done but it only got 5-10% through before it quit. After adjusting the power saving settings though the issue has not returned. These drives are great and I have recommended them to anyone else who needs a nice hardware encrypted drive that does not rely on software executables on the computer to unlock your drive. ... show more

What It Won't Do.....
Capacity: 1 TB Style: Drive Pattern: Padlock
I have five of these, and all are working fine. There is no noticeable performance loss due to encryption. From a NAS to the USB 3.0 Padlock I've seen burst speeds of 100MBytes/sec. (800Mbits/sec.), then it settles down to a steady 62 Mega Bytes per second. I've transferred a 2.6 GigaByte movie file in about 40 seconds. The Positive: 1. Because there's no software to install, it works with media players and should work anywhere you use a standard USB hard drive. I keep kid's movies on a standard drive, and my movies on the Padlock. No need to worry about the kids watching R-rated movies when I'm not around! 2. Multiple passwords allow up to ten persons to enter their own password using the alpha-numeric keys. This is very convenient if you want to use your Windows password to access the drive. All other encryption devices I have tried allow only one user password or have only numeric keys. A separate Administrator password allows you to delete or add other user's passwords. 3. Low power consumption - I have been able to use the drive on every computer or media player I have without the provided Y-power cable. What it won't do - the down side: 1. Although you can have multiple passwords, all users access the same data on the drive. It would be a real plus if file access could be controlled by which password is entered. 2. Rebooting your computer locks the drive even though power is never removed from the drive. I have a remote office and I do a lot of work using remote desktops. Occasionally I need to reboot the remote computer, and with this drive the data is inaccessible after the reboot. For me, this is a "deal breaker" and I need to stay with software encryption on a standard hard drive. It would be nice to have an optional software program to lock and unlock the drive. ... show more

Didn't work with Windows 10 and a Lenovo W530 out of the box - requires registry changes to get it to work.
Capacity: 2 TB Style: Drive Pattern: Padlock
I originally put this in as a 1 star because the product did not work out of the box. They symptom was after entering the security code the drive would disconnect after about 10 minutes of non-usage. It is a Windows 10 problem and after filling out the form at [...] support replied with the answer to fix the problem. Since then, the product has been working as designed. I would give this a five star for product as it is working as advertised, but the Apricorn web site has an FAQ without this information. It should be there. I lost a day reading all the problems on the internet with Windows 10 and usb drives and found the solution myself before their support organization could reply (they did reply within 24 working hours). The link is here in case it helps save you some time. It does involve modifying some Windows registry settings - Windows 10 is a fiasco: [...] Cheers - Pete ... show more

Reliable and secure
Capacity: 1 TB Style: Drive Pattern: Padlock
I love Padlock drives -- why? Nothing against software encryption, but if you're running in a non-native OS, or a non-Windows environment, you are at the mercy of the OS. This is nice and simple. Program your security code and done. Now, regardless of what OS you're using, it'll be seen by the OS. I've used them with MacOS and Windows just fine. ... show more

MAC OS X issues is Apple's Fault, not Apricorn
Capacity: 500 GB Style: Drive Pattern: Padlock
I purchased this drive based on the review in Wired magazine. I have been a technologist for 30 years, and I specialize in infrastructure theory, quantitative analysis, of Systems, Networks in real-time embedded systems. So I do know a thing or two about this stuff... I initially had problems and gave a one star review. Apricorn worked tirelessly to investigate the problem, despite the fact that MacBook users are really not the biggest target audience. Not that we are not important, but the target for this device is personal PC laptops, corporate, government agencies, and military. These people will have no such problems with this drive because the unique conditions I was using the drive for, and the original failure has more to do with Apple's engineering on USB 2.0 ports on older macbooks and not Apricorn, I felt compelled to recant my review and re-write it. This also says I have also been around long enough to know that you never see it all no matter how often you think you have and you aren't always right. Often as an engineer I am paid to find nearly any possible method of causing failure. In this case I had a failure, but Apple's older model MacBookPro's USB 2.0 ports just barely meet the required 500mA USB 2.0 spec... preserving battery life, (and I know Apple users won't be surprised by that!) but resulted in not likely providing enough power to the drive. Never the less, Apricorn does provide a Y USB power cable and on older Macbooks you should have enough power from two USB 2.0 ports if on the rare event you were to see this issue. If you are planning on upgrading or have already to Mountain Lion, you already likely have a late 2011 or newer 2012 MBP, and have no concerns. I do suspect that under some circumstances older MBP users that want to take advantage of the plug and play encryption technology may need to use the dual Y cable. e.g. 2010 or older. As you would likely suspect, the drives require more power on spin-up. I realize this is more reason for Pre-2011 MBP owners to feel more left out than they already did when Apple mandated new features, and Mountain Lion itself to run only on late model Macs. It should be no secret from the company that comes out with a new Iphone each year just in time for you to buy up and renew your 2 year carrier contract, that Apple wants you to upgrade your MacBookPro! Product genius and marketing genius over there at Apple. So Laptop users, stop reading and buy it, you will love it. I use it to store data that I don't use as often but still need with me. This data don't warrant me keeping it on my my internal 512GB SSD drive. If the drive is stolen, I need not worry, it will be wiped before they could ever decrypt it. I would just replace it. (Of course you are going to back it up right! That should go without saying for your computer and external drives, even USB) As for Apricorn as a company and their technical support, and entire organization that got involved, it is beyond outstanding. They really stand behind their products. ... show more

died on second use, click click clicking sound
Capacity: 2 TB Style: Drive Pattern: Padlock
Setup wasn't difficult but the drive bricked on second use. Copied over 100s of GB of files that I can no longer access. I enter PIN, light turns green and blinks green, then about 10 seconds later turns red and the drive starts clicking loudly several times per second nonstop. Listen to the other reviews, don't buy this junk. Apricorn put a garbage drive in this case, no more HDDs for me. I'd rather make several trips with a smaller, reliable SSD from now on. I tried it with auxiliary power cable and direct cable. No luck. ... show more
