[opensuse] OpenSUSE on SSD HDD
Hi, just received new Lenovo ThinkPad X301. It came with SSD HDD. Do I have to change something after standard installation? Or have to change some parameters when installing system? What file system is better for SSD? Any other important points to inspect? Thank you.

I have a Lenovo T400 with an SSD. Did not have to change anything
during install or after for the SSD.

Audrius, The latest and greatest SDD feature is trim/unmap. Not many shipping drives have the feature, but firmware updates may add it your drive in the future. It is a performance feature that allows the SSD to know which data blocks are not in use by the filesystem, so it can pre-erase those blocks and have them available for use in advance. The linux kernel does not yet have full support for trim/unmap (as I understand it). Current efforts target EXT4 / XFS / FAT. ext2/3 are not expected to ever grow support for this feature. OTOH, Mark Lord has a userspace tool to leverage unmap that is designed to be called on a scheduled basis (similar to how defrag is done.) Mark Lord's tool depends on fallocate support in the filesystem. ext4 and xfs at a minimum have that. I don't know which others. (ext3?) Mark is the maintainer of hdparm, so you can find the "wiper" script at: http://sourceforge.net/projects/hdparm/files/ Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Dear Greg, thank you very much for answer! I use EXT4 or XFS. Now have installed with EXT4. Before have installed opensuse in T61 with XFS and that was very pleasant system without any problems. I will look at script and try to use it. Audrius -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
