Recent releases will align partitions better for most flash devices (and newer hard drives) than older ones, people with SSD/CF storage might want to check if disklabel says the offset of the 'a' partition is 63 or 64, if it's 63 then it may be worth reinstalling with newer fdisk/disklabel. Probably depends on the controller how much effect this will have though.
Re: OpenBSD 5.1 SSD
Thank you everybody. I don't really use much space locally as my videos etc are on the network. I'll leave some space unpartitioned and let garbage collection do the rest.

Re: OpenBSD 5.1 SSD
doesn't support trim. i remember reading somewhere, maybe a freebsd mailing list, that calculating when to do trim is tricky because it can only work on a specific width On Sat, Apr 14, 2012 at 2:08 PM, Laurence Rochfort wrote: > Hi, > > I'm considering purchasing a domestic SSD for my laptop. > > Does OpenBSD 5.1 support SSDs and the TRIM command if needed? > > Regards, > Laurence Rochfort

OpenBSD 5.1 SSD
Hi, I'm considering purchasing a domestic SSD for my laptop. Does OpenBSD 5.1 support SSDs and the TRIM command if needed? Regards, Laurence Rochfort
