Your experience & thoughts on SSDs for MacMini

I have a 2007-2008 MacMini that I use exclusively as a music server on a third system with the stock HD. I am considering replacing the stock HD to an SSD. The stock HD makes noise that is audible often enough to draw unwanted attention to itself.

I'm looking for experience-based thoughts and commentary on the various SSDs that are available for this replacement. I'm using SnowLeopard and iTunes 10 with Pure Music for playback of AIFF files from a peripheral HD (which is silent).

So far, my research on this seems to get a bit confusing. For example, Other World Computing offers two levels of SSD, one over 50% more $ in price (and 25% larger 40 Gb vs 50 Gb than the other (offering a longer warranty, etc.) And I know there are several other manufacturers of SSDs out there with varying price points and related benefits.

This MacMini isn't used for anything else than serving music, ripping files, streaming audio, playing Netflix downloadable movies, and the occasional download from iTunes.

Your points of view are appreciated.

:) listening,

Ed

Tbg,

Are you assuming that SSD drives do not help when using Memory Play, or did you test it? If you tested it, it would be great to hear your impressions.

We have specifically tested this and found that using an SSD drive helps the sound, even when using Memory Play. I can't explain why, but the results were clear.

Now SSD drives are much more expensive than a regular hard drives so most people will decide it is not cost effective to use for external drives (although I use one and some of our customers do too.) I can't blame them, but our A/B tests showed a noticable difference.

..it would certainly seem conceivable that replacing an hdd with an ssd might affect (and hopefully improve) jitter levels and noise levels on the signal supplied to the dac.

The keys in that senetence are "might" and "hopefully", those are not reassuring words.
When you optimize the computer for music playback the access speed of the drive might be a non issue so controlled test with SSD vs. HDD should be made, one easy way would be to take once Mac mini with regular internal HDD and connect an external SSD. If the external sounds better we might extrapolate that to an internal SSD sounding better, but if the external SSD sounds worse or equal it might be the interface connecting the drive. Since Macs use USB or FW for external I would wager the internal HDD on Sata might outperfom.

Dmccombs,

have you tried a linear PS and can you elaborate how the sound changed when going from a HDD to a SSD?

Agreed.

I doubt that any meaningful extrapolation could be made. Regardless of where the music files are stored, the internal drive will be in use supporting the operating system and programs. And its circuitry will still be present and active, generating noise and causing (to at least a small degree) voltage droop, voltage fluctuations, signal crosstalk, ground-bounce, and other effects that could ultimately affect (to at least a small degree) the jitter and noise levels of the output signals of the Mini. All of those effects will differ between an ssd and an hdd, with little predictability.

Dmccombs, yes I compared the SSD versus an external HDD both using Memory on PM. I thought the SSD was slightly better but don't understand why.

Perrew, I would think the transfer speed from the HDD to the ram would be much faster with Sata, but would it matter?

As I understand it, what you are seeking is a processor that does nothing other than conveying the data from ram to the dac without jitter.

One final comment. I saw several demonstrators using memory sticks with big capacities for HD music. Some were using PM with Memory. It strikes me that several sticks with great capacity with one dedicated to jazz, etc. would be convenient. Anybody have any thoughts about this?
