What is the differances between a25-3pl256-1000 vs a25-3pl256-1000f? besides the keypad, what other features are in the "f" ver?

Hello, Craig from Apricorn here. cchristensen@apricorn.com The F stands for FIPS 140-2 Validated encryption. The National Institute of Standards and Technology (NIST) Validates products for Government use that meet their criteria. Apricorn products that have the letter F imbedded in them have been Validated by NIST. The products that don't have an F imbedded in them use the same encryption chips but they haven't been reviewed by NIST.

I work with data very few people can see. I would rather lose the data than have it retrievable by Aegis, can the back door be locked?

Hello Craig from Apricorn, cchristensensen@apricorn.com There is no backdoor on these products. The data is protected by 256-bit AES-XTS encryption. The drive itself creates the encryption key that it generates through its own random generator. The drive is the only thing / place where the key is (stored encrypted) and without the key, you can't get to the data. If the drive is lost or stolen and it will wipe the encryption key if it detects a brute force attack rendering the data on it useless.

Will it backup automatically considering it has a keypad to access?

It can be used with backups provided that you're computer does not put your USB into power saving. I use mine for the express purpose of backups to help protect them from theft. However, if USB loses power, then the code will need to be re-entered. This is particularly of concern on people that have laptops or tablets with power saving features such as a surface. We had issues with the surface devices but this was corrected by a registry key adjustment to ensure that the USB ports aren't powered down when idle.

What happens if someone cuts the USB cord?

Pretty much the same as if you cut the cord to any electrical device. It won't work.
