SanDisk Professional 4TB G-Drive ArmorLock SSD - Encrypted NVMe Solid State Drive, 1000MB/s, USB-C, High-Level Security, Ultra Rugged - SDPS41A-004T-GBANB

If you do everything on your home/office computer then this device is perfect for your peace of mind knowing your more private information is secured. I especially when I get a report from my Interprovider and Norton Antivirus that our Modem was hit/blocked with over 300 attacks in one month. This caused me to purchase this device and remove all my family/business documents on this device. I love the fact that no one can access it unless I unlock it and when I leave my office or if I forget to lock it when I leave the house. I can just use my phone to lock from it anywhere. It's easy to setup and yes you need your cell phone to unlock the device. Think of it as a 2nd Authentication you use for your bank or email accounts. With the need of a 2nd device to verify you wanted to open/unlock your files you know not just anyone can gain access to your personal information. My only recommendation is that they provide a longer cable for Desktop users where the USB ports are on the back of the PC and with their provided cable the device will hang unsecure. Unlucky for me I had an extra port on top of my PC to allow me to plug in without having it hang off the back. I used the box it came with to create a buffer away from the PC. Two Thumbs up!

This is a great idea in theory but execution is TERRIBLE. The armor lock feature should be able to be turned off and the app developers need to fix some serious issues and bugs before you sell this to another working professional. I have wasted so many hours of my life and my energy trying to connect these drives. Not trying the first time, but trying almost every time I plug the drives into my computer. Forget about trying to give this drive to an editor or to a client because they will never get into the drive. Sure they are very fast but I've wasted so much time connecting these drives that it ends up being slower that a 7200 rpm drive. Save your money and buy one of the other SSD drives without the armor lock.

I'm sharing my feedback because, like many or my work associates and friends who daily push huge amounts of data and large files, I'm always looking for efficient tech solutions. I have been using this drive for a few weeks, with no issues at all. I do not have any high degree in computer technology or IT, and I was able to set up my ArmorLock drive and have it working in 15 minutes. It's a fast backup storage solution that is secure. As another reviewer wrote, definitely save the recovery codes! Which is easily done. I backed them up on my desktop and in an email. Also, before buying this drive I called Western Digital for more information, and they provided great customer support.

I still have not figured out how to get this to work. You must have a Computer Degree I assume it is above my head and I work with Computers daily. I even had my friend who is very Tech Savvy to try and help me make it work and he gave up! I had planned on sending back but time ran out. At this point such a waste of my money not to mention frustration.

Do not buy this drive. On January 5th 2026, Sandisk ended their support for Armorlock to access drives and removed it from the app store. I'm very lucky to have seen the notice, managed to unlock all of them in time, and spent several weeks backing up my drives just in case as they can "stop working at any point in time." They could anyway, but SanDisk didn't give much notice. Only thing I'm grateful for is the kick in the pants to do redundancy again.

When you get a new phone, restore your phone, or delete armorlock app you will lose the connection to your drive. Save the recovery key in a safe spot bc if you make the mistake of losing it on a backup drive there is no access to your drive. I lost everything bc I had no clue restoring from a backup to my our phone breaks the connection to the drive. Armorlock seems awesome but I lost everything to this stupid idea.

Seriously? Only apps made for Mac, Android and iPhone? How lazy does the developer of this drive have to be to not sell a universally compatible drive? Now I have to explain this to the heads of major company who invested in these that we made a huge mistake going with SanDisk. What a joke and headache!

It's a disgrace after owning this for over a year that the product support on this product is ending in January 26. I tried to move the app to a new phone and scan it in but this could not be done. Best to steer clear of any SSD encrypted drive that needs a phone to turn it on or off

The ssd worked great once I worked out the reason that it kept connecting and then disconnecting was due to a faulty usb c to usb c cable. Not the end of the world but annoying at this price range. Also had I not checked the cable I would have assumed the product was faulty. Other than that, a great product which was quick and easy to install, not sure about the formatting comments from other users as this happened automatically in the fast installation process and required no imput from me other than choosing my required format. For anyone who requires a secure ssd this is a great choice and I would be happy to leave a 5 star review was it not for the faulty cable provided with the product.

Produkt entspricht vollumfänglich den Erwartungen. Da das Gerät ggf. für MAC vorbereitet ist und die Vorbereitung nicht nur beim PC sondern auch ggf. beim MAC nicht den eigenen Vorstellungen entspricht oder nicht funktioniert über die App: Die Umkonfiguration einer bereits eingerichteten Festplatte vom Status "immer entsperrt" in den gesperrten Modus funktioniert ggf. nicht: Abhilfe: keine manuelle Umformatierung der Festplatte für den PC oder dergleichen. Direkt bei Auslieferung die App mit der Festplatte verbinden und über die App die Festplatte zurücksetzen (siehe Bild zwei, in den Manager-Einstellungen "zurück auf Werkseinstellung". Dann läuft der Assistent sauber durch und alle Parameter einschließlich der Voreinstellungen für die Nutzung am Windows-PC mit NTFS-Formatierung der SSD funktionieren tadellos. Aber bedenken: diese Einstellung ist mit vollständigem Datenverlust aller bisherigen Daten auf der SSD verbunden. Ich beschreibe hier die ERSTeinrichtung.
