Your experience & thoughts on SSDs for MacMini

Perrew,

You killing me man. Please read what I wrote and quit "extrapolating". Take my words as they are written. There is no hidden meanings... I never mentioned any preference for either power supply. I never said we didn't A/B test internal drives.

We have A/B tested internal SSD vs. regular HD. We build Mach2 servers every day. It is easy for use to listen to a Mac, swap the drive and listen to it again. We also have plenty of Mach2 servers around to compare to stock.

Internal drives are typically small compared to folks 1-2 terabyte libraries. If have a small library you can store it internally.

Happy Listening,

Dmccombs, thats not my intention:-)

Without extrapolating then, why do you not have linear PS or battery on the server?

So how did the internal HDD compare to an internal SSD?

SSDs are getting quite large so with two of those you can cover quite large librarys.

Im just trying to learn here how to best optimize my server.

Perrew,

An internal SSD is way better than a regular hard drive, sonically. The only thing to decide is how big you need (or can afford).

I hope my comments regarding the value of SSD vs a regular hard drive have been helpful. I'm sure others will chime in.

I'll skip the power supply questions so we don't derail the thread.

According to several trusted audiophile ears I've talked to (both Win and Mac users), there is no difference they could hear with internal SSD against HDD.

Even with a 5400rpm 8MB buffer HDD, burst-loading of the entire audio track to the system main SDRAM takes a second or less. What about Barracuda XT drives with 64MB buffer? HDD jitter? No such thing, IMO! And let’s not forget that the SSD also has a SDRAM buffer, just like HDD.

It does not matter where your audio file is stored; it is always double buffered (at minimum); first in the storage device own memory buffer, and again to the main system memory. So I do not see a reason for SSD to sound better than HDD.

Best,

Alex, no one has mentioned "HDD jitter" in this thread, which I agree is a nonsensical expression. A question was asked as to how changing from an HDD to an SSD could affect sonics. I responded that jitter and noise on output signals of the computer, that will be connected directly into a dac in many setups, could conceivably be influenced by crosstalk, ground-bounce, voltage droop and voltage fluctuations at various circuit points, rfi, and other similar effects that in ANY digital design that involves a large number of signals that have fast edges can result in subtle interactions between circuits that are ostensibly unrelated. Particularly when the destination to which some of those signals are sent (the dac) may be especially sensitive to small amounts of noise and jitter.

I take no position as to the likelihood that using an SSD instead of an HHD will make a sonic difference in any given computer, or as to whether the difference, if any, would be for the better, or if any such effects would be consistent across different computers, because I have no experience upon which to base such a position. What I have said is simply that it is technically conceivable that there could be a difference, in at least some setups with some computers and some dac's. I don't think that is disputable.

Best regards,
