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!
