Well, theoretically you will have more track-to-track seeks, as some blocks will span cylinders, but I doubt that will have measurable impact on lifetime, compared with the gains you could harvest if you spin it down for even just 1 hour a day... Read-Only/Read-Write makes no difference that I know of for hard-disks. >and one other question: the hdd also supports usb 3. will the improper >alignment have any effect (speed wise) when connected via usb 3, or is even >usb 3 too slow to notice the performance drop due to the improper alignment? Again: I doubt it will be measurable. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk_at_FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.Received on Mon Dec 19 2011 - 22:01:16 UTC
