Speaking of durability, this has a very interesting characteristic that I very much like. Unlike an SSD, DRAM has inherently very poor data durability and it is very easy and fast to erase anything. Unfortunately, since they are using a SSD controller, this might still not do what I expected it to do, but one of the big problems with SSDs is you cannot delete anything once written. You can secure erase all of the drive, but not just a few files, you only have the manufactuerer respecting TRIM.

The hope here is that because this controller uses DRAM, the contents of the drive can truly be erased quickly on command, while leaving other data intact.

One use case for this would be systems where file level encryption is untenable, but data can potentially be recorded that you would like to cryptographically remove. It would also provide plausible deniability for erasure of contents.
