Mac OS 9 & SSDs?

[avw]

I am planning to get an SSD for my Pismo/500. I belive it is the upgrade that makes most sense, and would be doable for about 50 Euros for a 60GB model plus SATAII<->IDE converter recently.

Are there any experiances with Mac OS 9 and SSDs? I read much about Wintool this and Linuxtool that. Should I expect some troubles, or should in general any SSD work out of the box? Just partitioning HFS+ with Mac OS 9 standard tools (ok I have HDToolkit and HD-SpeedTools at my hand as well)?

I am NOT asking about X!

My impression is that it probably works, but there is no TRIM support, of course, so you'd start to see performance degradation after awhile. It's an expensive thing to experiment with, but I don't think it would *not* work.

Well, thats similar to what I belive. Of course there will not be any AHCI or TRIM support, but "Garbage Collection" should do the trick - at least for a while. As recent SSDs get up to 500MB/s reaching the 66MB barrier of the Pismo, when decreasing the performance over the time, should be enough "headroom". Isn´t it?

In fact I am more concerned about the ATA66 to SATA II converter issues. The question is if I should give it a try with all this questions Mac OS 9, IDE/SATA, SSD, ... but if it works, having 66MB/s immediatly availaible should be the highest possible boost for a Pismo I can imagine (compared to expansive RAM upgrades, or unavailaible Bluechips, ...).

Any further comments?

Edit: and as the Pismo is recently my main computer I am very interrested in a little improvement!

You can get SSDs with TRIM support in the drive itself. Sandforce controller in the OWC range (check the specs) has TRIM native.

I recently installed in a 32GB IDE Transcend drive into my Pismo 500

I started up with Mac OS X 10.4, fired up disk utility

Initialized (HFS+) and partitioned the drive in two.

Then I installed Mac OS 9. Restart-option key

The system boots quickly and silently.

The only issue I do have is that sleep mode in Mac OS 9 crashes the machine.

However, putting the computer to sleep in OS X does work.

The mind boggles and I don't know why.

My experience with OWC stuff is very well. Their SSDs for recent MacBooks work like a charm. They offer SSD options to uprade even aged machines. After buying many adapters from different sources with various results I would strongly recommend to put money into a solution that is positively proven to work well. If OWC advertises a combination as operational, you may trust them usually. Most other suppliers of similar stuff might not even be able to tell you if some component fits physically into your computer.

I put a mSATA to 44 pin ide adapter in a Mac mini G4 with a ATA 100 bus, running OS 9.2.2 and it seems to work fine.

Is there anything that you want me to test on it? Or “give it a try”? It’s an experiment anyway, and of 120gb, I have 118gb left. That old stuff doesn’t take up much space.

... And yes, it’s the hacked/ patched OS 9 made for the Mac mini from OS9Lives.com.
