Installation on SSD slooooow

[seye]

Hi

 

I bought a 32GB Transcend SATA SSD and wanted to install OSX on it. The drive is hooked up to a ICH9R controller.

The performance of the drive is rather good when used as a data drive (non-boot). But as soon as I boot from that drive the read/write speed drop to around 16 kB/s.

 

A fresh installation of OSX takes about 5 minutes to boot. (Compared to 8 seconds on a normal drive).

 

I did two installs. One retail and one from the Kalyway DVD.

 

So far I've only tested with EFI bios and GUID partition table. I'll try a MBR install today. Maybe it will be faster.

I'm also going to test-install windows to see what happens there.

 

Has anyone encountered similiar experiences with a SSD? Would it work better with a faster SLC disk instead of a MLC disk? Or is it simply a bad unit?

 

The disk only has a SATA-1 interface. Could this be the problem?

 

Regards

Simon
