In order to maximise user experience thus performance, we need to ensure the disk partitions created on SSDs/USB flash drives/RAID arrays are 4KB (perhaps up to 128KB) aligned. There are considerable benefits with the flash/RAID controller opening half as many pages/stripes on small reads. This pays better with slower SSDs in eg netbooks.
Patches have entered the upstream kernel to detect when drives are solid-state [1], though the dust hasn't settled on the interface. How acceptable would getting the userspace partitioner changes into Jaunty if proven to be stable and robust? --- [1] http://groups.google.com/group/linux.kernel/browse_thread/thread/b8556b1cd1af57f/b9dd80a08afc0b5e -- Daniel J Blueman -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
