Za klasicne diskove je od presudne vaznosti ... pogotovo za RAID 5 polja na OB kontrolerima, a ima znacajnog pomaka i na dedicated karticama.
Istina je da je Vista bolje pripremljena od XP-a, ali ...
U slucaju SSD-a sam pronasao clanak od strane Linux kernel programera koji je slijedeceg misljenja:
Vista has already started working around this problem, since it uses a default partitioning geometry of 240 heads and 63 sectors/track. This results in a cylinder boundary which is divisible by 8, and so the partitions (with the exception of the first, which is still misaligned unless you play some additional tricks) are 4k aligned. So this is one place where Vista is ahead of Linux…. unfortunately the default 255 heads and 63 sectors is hard coded in many places in the kernel, in the SCSI stack, and in various partitioning programs; so fixing this will require changes in many places.
However, with SSD’s (remember SSD’s? This is a blog post about SSD’s…) you need to align partitions on at least 128k boundaries for maximum efficiency. The best way to do this that I’ve found is to use 224 (32*7) heads and 56 (8*7) sectors/track. This results in 12544 (or 256*49) sectors/cylinder, so that each cylinder is 49*128k.
Dakle, uvijek moze bolje i brze ... a kad se u ovo ubaci kombinacije stripe i cluster size-a onda stvari postanu jaaako zanimljive ...
