Microsoft have released a new blog post on their Windows 8 development blog.
The post, written by Bryan Matthew, a program manager on the Storage & File System team discusses the work they have done focused on scale and capacity.
They identify two key challenges regarding data management on really large drives:
They go on to say that a side benefit of UEFI firmware is that it will handle larger disks better ergo it is one of the reasons that Windows 8 will require UEFI.
…the UEFI specification was developed as a replacement for BIOS and implementations have existed since the late 1990s. UEFI was designed from the ground up to work with very large capacity drives by utilizing the GUID partition table, or GPT…Beginning with Windows 8, multiple new capabilities within Windows will necessitate UEFI. The combination of UEFI firmware + GPT partitioning + LBA allows Windows to fully address very large capacity disks with ease.
Microsoft are saying that they fully expect Windows 8 to install on disks larger than 3 Terabytes.
In addition, they are stating that Windows 8 is the first OS with full support for both types of AF disks – 512e and 4K Native. They go into much more detail on the blog..
Basically they have addressed the following issues..
The bottom line is, with NTFS in Windows 8, Microsoft will fully leverage the capabilities delivered by their hardware partners to efficiently support very large capacity disks.
