That is, in all the cheap ones? Somehow early reviews managed to miss it, so I'm stuck with one, and will eventually replace it with something faster -- and then will be looking for a way to use it productively. Or has all the testing centered around enterprise-grade stuff and nobody knows about the cheaper drives' performance? (There's a problem in the MLC SSD drives with particular JMicron controller chips where some patterns of small writes trigger ~~10sec. hangs, which is most often called "stuttering" in online discussions of it that I've seen. Using it as a Windows system disk unfortunately hits these patterns far too frequently. My particular example is an OCZ Core 2 64GB unit. Oh; I should say I've been through the list of registry tweaks, and I can't see they've helped more than a little.) -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
