Hard Drive versis Flash Drive


Hello,

I am planning to buy/build music server based on either MSB DAC or new PS Audio PWD DAC. Meanwhile, I want to start process of ripping CD's. I have not too many may be 500 or so. My question:

Is sound quality differ from storage on hard drive versus that on flash drive ? On one hand, flash drive, as far as I know has only UPS port which is not the greatest for music whereas hard drive may have other digital outputs like HDMI which is (are) much better. On other hand, solid state memory was shown to be superior (for sound again) over magnetic moving memory like a hard disc.

Also, if to use USP port then Flash drive seem to me clearly better (on paper) for one more reason - you plug and play whereas with USP based hard disc you need to use USP inferior cable.

Much appreicate if members will share their sonic experience with these two types of the storage.

Another question: what type of ripping software is the best for sound, and later on for ease of navigation? EAT, Monkey etc.... 955 of my CD collection is classical which may make a difference in navigation, I suspect....

Thank you
Rafael

Like Almarg said, the audio data is sent from the storage to the computer via high speed bi directional error corrected bus, and it shouldn't really matter whether the source is magnetic drive or solid state. On the other hand, SPDIF, HDMI, or USB audio signal is sent over unidirectional bus where the devices on both side need to synchronize on the clock embedded in the signal, thus the timing error or jitter may affect the sound quality.
Being mechanical design doesn't mean it's more prone to the failure. Over 20 years of owning various computers, I have had one hard disk failure but more than half dozen memory failures. Solid state drives do not have moving part, but don't make an incorrect assumption of solid state being more durable. Agreed on the heat, power consumption and noise.
Have also had a half dozen memory failures. Unfortunately, none had to do with flash or hard drives!
