I believe the ATA TRIM draft standards specs don't have the 1-4 megabyte; that craziness is only coming from the SCSI world. So we do have more information than what Intel has released; also, note that OCZ is the first vendor who has shipped publically available SSD firmware with Trim support. Supposely Intel is going to try to get me their trim-enabled firmware under NDA, but that hasn't happened yet. > > As far as thinking that the proposal is ludicrous --- what precisely > > did you find ludicrous about it? > > Mainly the idea that discard requests should act as barriers and instead > of fixing that, you propose a lot of complexity to work around it. I can't fix hardware braindamage. Given that the standard specifications is terminally broken, (and we can't really fix it without getting the drive manufacturers to rip out and replace NCQ with something sane --- good luck with that) the complexity is pretty much unaviodable. Still think my proposal is ludicrous? - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
