Re: FreeBSD on SSD on ASUS P5KPL-C
Thank you very much for your work on this. I have found this conversation and your article very informative. I've already installed W7 on my SSD but I let the installation program create the windows (MBR) partition. I'm going to install FreeBSD 9.1 as soon as it is ready so I want to ask if it is straight forward if I follow your instructions for creating the bsd slice and partitions, or if I need to check anything in order to get the correct alignment?

ZFS or other filesystems will also benefit from block alignment, but the methods to get there can be different. The step of using gnop is meant to trick zfs into believing the disk has 4K sector size to improve performance, which I would think zfs would be able to figure out by talking to the disk. Unless ZFS is put on a bare, unpartitioned disk, configuration for performance is better left to the user. It's a pain to correct automatic configs when they guess wrong. Does partitioning hide the sector size or would the step of aligning the partition start to a 4k sector unhide the 4k size? Or are these steps just a waste of time? It's not about hiding the device's native block size, it's about getting the filesystem to do aligned I/O so the device can just read or write a single 4K block instead of part of one and part of another. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

FreeBSD on SSD on ASUS P5KPL-C
Hello, I'm about to upgrade hardware on my desktop and to install FreeBSD 9 on it. I have ASUS P5KPL-C and want to buy a SSD or SATA-III 6Gb/s drive for it. Please advise me: * does it make sense to buy SSD drive for a mb that supports 4x SATA 3Gb/s (of couse, expecting a possible future mb upgrade)? * if SSD is capable of working at greater speed, will it simply operate on maximum 3Gb/s on P5KPL-C? * the same question for SATA-III 6Gb/s. Will it simply operate on 3Gb on my mb? * How will FreeBSD 9 behave in such situations? Any special tweaking needed?
