Jylee - DSD in SACD is PWM done at 2.8MHz. Quality wise it should be equal to 20/96 but as far as I remember resolution of the modulator is in order of 8 bits and higher resolution is achieved by dithering. Converting it to PCM on digital side would require to read asynchronous signal without any slightest timing errors possibly not getting better quality than redbook layer. It is possible to A/D analog signal to PCM but then you have extra conversion.
Esmith3671 - Hard drive is not operating in real time. I'm not sure if you can store DSD there the same way you can on SACD on tape. Getting SACD to hard drive is difficult since there is no SACD computer drives. In addition there is strong copy protection and pit-width modulation that drive has to be able to read.
