These defaults are selected to reduce the space that is lost and to reduce the fragmentation that occurs on the partition. The default values are used by Windows when one of the following methods is used to format the partition:. This is because NTFS file compression is not possible on drives that have a larger cluster size. The format command won't use clusters larger than 4 KB unless the user specifically overrides the default settings.
When you use the Convert. This is because the FAT structures are aligned on cluster boundaries. Therefore, any larger cluster size would not allow for the conversion to function. Note also when formatting a partition under Windows NT 3. Need more help? Expand your skills. Get new features first.
This is about Itanium, which is existing architecture, but not x64, which is what people usually mean when talking about 64b Windows. Suma x64 bit architecture came from Itanium. Same way that most of x86 architecture of say, pentium came from — Aniket Inge. No, it did not. It has nothing in common with Itanium. Itanium was first, developed by Intel, and was a radical change from x Itanium was not used outside of the server marked. See e. Itanium Wikipedia "AMD chose a different direction, designing the less radical x, a bit extension to the existing x86 architecture" — Suma.
Rereading the quote now, I have to correct my comment a bit now. While the quote is mostly about Itanium and its emulation, it contains the information about x64 as well, explicitely stating "This is not the case for the x64 processor".
This means the quote provided shows x86 application gets 4 KB pages on both Itanium and x The correct answer to this question is "It depends on which processor". Itanium uses 8KB pages. Mats Petersson Mats Petersson k 13 13 gold badges silver badges bronze badges.
This is correct, however as the quote in Aniket's answer shows, even on Itanium the 4KB page is emulated for x86 apps. Sign up or log in Sign up using Google.
