External HD VS Flash Drive Sound Quality Question


Hi have an Oppo BDP-95. I am up to around 25 Flash drives which is getting ridiculous.

2 questions (hoping for folks who know the definitive answers; I have my own guesses, bu that's all they are.)

1. HD Tracks has written that the Flash drives sound better than any spinning disc or drive due to lack of jitter from lack of a spinning disc. Is that accurate?

2. I have noticed a new generation of external hd's that get all there power through the USB port, & do not require an out board power supply.

A. Would there be any detectable sonic difference either way? If so, which is better: the cheap wall wort power supplies or getting power solely through the USB line?

B. The Western Digital USB drives with no power supply have a proprietary cable that looks quite cheap. Would the lack of an audiophile USB cable be sonically problematic?

I'm basically trying to decide whether to ditch the lash drives or a USB hard drive; & if so whether to go with a powered or unpowered drive. A couple +'s re the new WD's: they are teeny & they run cooler than the Seagates I've used.

Very interesting Dchan88. I would have thought the SSD to slightly outperform the spinner. Thanks
I would also have expected the SSD to sound better. Interesting.

The HD is here. It's taking several days to transfer files (partly due to the amo8unt, partly because I am trying to make 3 drives identical & the other 2 weren't quite there); should be able to report back next week. The USB chord is the same semi proprietary cable that Western Digital uses; I'm not sure if there is an audiophile option.
A few VERY INITIAL comments:

1. It works!

2. It's definitely putting out a lower (digital) volume level than discs or flash drives. No idea why. Not a big deal, I'd say I'm turning the volume control 1-2 clock markings higher

3. I decided to use an older hard drive that does not have the proprietary usb jack, so if I ever do have the $'s to try an audiophile cable, it would be an option.

4. Due to the layout of my power conditioner, I can only plug in the wall wort in 1 direction, so I can't test the audible effects of polarity unless I use a cheap power strip or plug straight into the wall.

5. I really feel I need at least a couple weeks to make an accurate statement regarding what I'm hearing (other than the volume drop, which is not subtle). My INITIAL reaction is: not bad, but seems to be a bit less of a sense of depth & sound stage on i-res, 44/16 sounded about the same.

I'm going to take some time o get used to the current sound, then do some a-b', then I will report back.

I have a suspicion that despite some comments above, the cables are going to have an impact. Of course the problem with subjective hearing is we often hear what we expect to hear, unless it's really obvious!

The benefits for me is not having o have all those flash drives (& possibly eventually moving a huge disc collection to hd's) & as compared to Flash Drives, everything is sorted by genre & alphabetically o I don't have to look at a list to see what album is on what Flash drive.

But the sound quality will be my real determination.
Either I'm going brain dead, or my "s" & "t" keys are intermittently not working (or both......)

If so, I'd expect that the reason is not that the hard drive is "putting out" a lower volume than the discs or flash drives, but that for some reason the player is treating the data that is received from the hard drive differently than the data that is received from the other media. Perhaps shifting the data within each sample by one bit location, at some point in the data path, which would probably result in a 6 db change in volume.
