Once I partitioned a disk in 20 or 30 partitions, and tested speed on all of them. The faster region was about 1/3 of the disk. It was slower at the end of the disk than at the start; that I expected, but not that it would be faster at 1/3.
Confirmed via observation here, closer maybe to 25%, but clearly slower at the front than somewhat beyond the front, with the rear very clearly bringing up the rear in performance. It wouldn't surprise me if disk makers were putting LBA 0 somewhere other than the physical start. ==== Someone should go tell Tom's HW to update their graphs... Never seen one with a slower speed at the start...
That doesn't make any sense unless you have bad sectors there... or maybe they are putting spare sectors at the outside on some disks? I've never encountered those symptoms on any drives I've benched, but also I'm almost always running Enterprise drives for reliability. Same for your tests? Brands? I'm usually Hitachi, Fujitsu, Others are not ones I usually buy but have some...course now Hitachi is WD? ARG...wonder if they'll keep the facilities separate...never had good luck with WD's... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
