    Samsung provides specs and a lot of technical information on their SSD's. Other SSD and HD manufacturers are more secretive.

  • It depends on a variety of factors, such as:

    1. The mechanical damping in the disk drive.

    Don't HDD's have CACHE. 32MB is common and on Hybrid HDD's 8GB is common.

    Now you have Intel Optane.
    3. The electrical noise characteristics of the SSD or HD controller (very important).

    With the fetch operation not being realtime and being very burst in nature.
    5. The storage topology of the SSD, (2D vs. 3D) and size of the SSD's memory cells. The smaller the cell size, the greater the potential for increase in electrical noise.
    6. Speed, size, number of platters in the HD.

    With my Bryston BDP-2 digital player, I went from an internal Samsung SSD to an external HD because music from the HD sounded better.

    I wonder what this looks like if one creates a silent .wav and plays this back and captures the output into an ADC with ARTA.

    You could always get a NAS that supports iSCSI and a NIC as well and do diskless workstation.

    Man, it sucks I am so paranoid. I have one HD that seems to sound better outside of the internal SSD (too small to hold everything) so I move it back and forth between my systems. I actually have everything backed up on a NAS and like three other portable HD's. I do know that the one that travels with me sounds worse than the home version. I never play from the other ones, I just make sure they are up to date. Hell, it keeps me off the street.

    I am weary of the chase. Are you guys sure about DNLA?

    Oh and I just busted my good sounding portable HD

    all dang Sorry Bruce.

    myself I still really liking the internal SSD 1 TB drive i have in my Mini and have no plans to switch to external or NAS at this time!

    As I started a song on my mini and my SACD at the same time and use the source button on my preamp to switch between them and my Hi-Rz files sounded just as good as the SACD for the most part depending on which album I was playing.

    "IMO USB is the best choice for Aries Mini, though it can be further helped by adding galvanic isolation. I use Intona USB Isolator (industrial edition) for this.

    Also, as with the Aries Femto & Aries LE, the sound of the Mini can be improved as follows:

    * Avoid adding local storage (increases electrical noise)
    * Stream in WAV (PCM) instead of FLAC/ALAC/MP3 etc. to remove the stream decompression workload from Mini's processor
    * I take advantage of MinimStreamer to do FLAC-to-WAV decoding on the NAS
    * Use good linear power supply to replace the included SMPS"

    My internal SSD maybe adding some noise?

    but it is so kənˈvēnyənt to use the SSD with the Lightning app that I could never go back to external or using a NAS/PC setup o:)
