Depends on your use case. If you have SSD attached over USB3, you can easilly pull 400MB/s. This would severely limit that, if that is an encrypted drive. On Allwinner H6, for example, you could get that speed on oncrypted drive while still having other cores free for other stuff. So if you need to go through/process gigabytes of data on encrypted drive, having to do encryption in SW will slow you down massively, especially if you also need to process the retrieved data somehow.
