Seems hard to believe, but you never know. Did you capture the different signals and do a null test?
Do remember reading that SSDs were a nono for recording audio, can't exactly remember why, but then I also remember reading that the issue had been sorted. Sorry, not much help I know!
Some factors that may contribute to playback differences of identical data between HDD and SSD could be:Jitter in playback from reading the data from the HDD due to increased and variant read latencies -- if this were the case, the fault would more likely be with the playback software for not having a realistic buffer.If the analog audio out interface is inside the computer, EMI from the HDD servo's (or even the spindle motor) could be injecting noise into the sound card as the hdd arm is moved to seek and read dataSimilar to the point above, mechanical vibration from the HDD seek activity could be causing a component on the sound card to vibrate (oscillate) in an undesirable manner.I note these. At first I thought highly unlikely, but still possible. There are probably a few other really esoteric factors that may be considered as well.I would recommended capturing the output of each playback with another audio interface and DAW to compare and analyze to see what is different.One simple test would be to use a simple sine wave test tone for your playback source. It's regular, and predictable. When working with regular music, it can look effectively random and can be hard to see problems on a scope without using advanced analysis tools.
Thomas why do you say it is impossible ? I believe there is a fundamental difference in the drives in that the mechanical Sata drive contains a motor and moving parts whereas the SSD drive does not ; so even at the most basic level when replaying the same music from the the two drives the mechanical drive is also creating it's own low level of physical background noise plus possibly creating EMI from the motors. What may be impossible is if the files contained on the two drives sounded different when transferred onto a third party machine with a separate SSD and then replayed.Well this is my wild theory at least All the very best - Andrew
Yup.. Same here. Win7 64bit and I have the C: SSD set-up to back itself every 7 days to the NAS, so, in case of a C failure, I roll back to an event within the 7 day mark. A loss I'd have to live with. But, at least no re-installations etc..Ciao'KAyo
I know it is impossible and we are working with "1" and "0" but my ears tell me that I have much better transient response from my newly installed SSD work drive.Here is what I haveCustom built computerSSD drive for the main drive and and new SSD drive for a work drive. Both are Samsung EVOsWindows 7 Pro with all the updates8 Gigs of memory2 SATA drives for work drives.Quad Core Intel processor chip NIVIDA Video cardRME audio card.Wavelab 8.5.3 for my DAWIf I play a file off the SATA drive it sounds great. When I play that same file off my SSD drive I can hear so much more of the details and the space around the instruments. Not sure what is going on. I know from an engineering standpoint they should sound exactly the same...but they don't.Any ideas? Thanks in advance.
