I wonder how much this affects the read and write speed?
Hopefully it will not affect the read/write speeds at all. I believe Toshiba has released a SSD similar to this, in which the read/write speeds are the same as a regular SSD so hopefully the same will be for this drive.
Treacherous Computing, er... Trusted Computing's main use is to support DRM and create customer lock-in. I don't want any product associated with the TCG, even if it seems as harmless as this one. The less traction they get, the better.
