I have upgrade my iBook G4 to SSD on 2013/10/11 Fri. The disk access feels much faster than the internal 4200RPM IDE or an external FireWire 7200RPM 3.5″ WD 160GB IDE. The left acrea near my hand also feels much cooler.
Here is the disk test result by Xbench 1.3 on MacOS 10.3.9. The bottle neck should be IDE and the SSD to IDE convertor. A SSD with native Sata 2/3 will perform even better. Compare to other IDE drive, the transfer rate is improved. Also, the SSD should perform better on access time than hard drive.

The SSD and SATA to IDE Adapter
The 30GB SSD comes with a Toshiba T6UG1XBG controller which is the same as some Mac Book Air and Kingston V+ 100 series.
Why Choose SSD with Toshiba T6UG1XBG controller
I choose it for two reasons:
- Size – it’s too crowded to put both an 2.5″ SSD and a SSD to IDE convertor
- Trim – MacOS 10.3.x doesn’t support Trim. To keep the SSD performance top, I need a controller which may do garbage collection more aggressively.
This small 30GB SSD looks like the photo in AdvandTech’s review of Kingstone SSDNow V Series and they also provides a very detail explain and comparison on how Toshiba T6UG1XBG handle with garbage collection.
