Kali Linux on a Raspberry Pi with LUKS Disk Encryption

Does disk encryption on an SD card cause write amplification at all?

I've killed two decent genuine Sandisk SD cards already in under a year and would worry that this would blast them even quicker even if it is desirable to encrypt the disks.

I'm wondering if you could use a Pi effectively since I gathered that penetration testing is quite CPU intensive.

it's good that they credit the ofthedeed guide for raspbian at the end, which in turn borrowed a lot from the paxswill guide for raspbian. the ofthedeed guide has an image ready to go, which is convenient but not for the truly paranoid.

i've read about a 50% i/o performance penalty for this setup but 50% of not a lot is still not a lot, so most people won't be too bothered by it.

I'm afraid it's gonna be very slow due to LUKS encryption and lack of support for it in the CPU.

Does anybody seen any benchmarks?
