Windows 8 adds RAID-like storage pooling

An interesting article was posted to MSDN blogs, thorough overview of Windows 8’s new features called "storage space". The technology will allow users to create a single storage volume from multiple storage devices. This feature also allows the user to fly by adding more devices dynamically expanding storage space of the volume. Storage space available for the user to provide such free passage between NTFS volumes intelligently organized and available space.

For example, Windows users will be able to offer a single volume 8 D: a confused mixture of any storage device. If the user space gets low, they can simply pop on another hard disk or plug another external disk drives and storage space will expand d: to include new devices. More important is that this is not going to lose data.

Storage device that allows NTFS format in the 'pool' and break it down into 'space '. The pools are similarly storage devices work spaces JBOD RAID array (just a bunch of disks) is more similar to the collection of partitions at the same time. JBOD array functionality to protect your data from disk drive failure. Similar to the storage RAID 5 using the same data, to provide fault tolerance strategy.

Although they share many points of convergence, storage space is not a RAID solution. The FAQ States:

Basically, the storage can be virtualized storage to enable cost effective and easy to use manner with plenty of features. Physical disk failed (and other similar) by maintaining multiple copies of the data storage book resilience. To optimize performance, storage space is still striped data across multiple physical disks. While mirroring and striping of RAID storage space used within the concept, in order to reduce the complexity of application users to optimize, maximize physical disks and assigned the flexibility and quick recovery for physical disk failure. According to the objectives and implementation of the storage space and inflexible traditional RAID to achieve these significant differences, RAID the nomenclature is not used storage space.

Currently, there are hardware and software technologies that provide similar benefits, such as LVM, ZFS, Drobo, high end RAID controllers and so on. However, disk space seems to provide a lot of flexibility and simplicity. The function has at least found in Windows "dynamic disks" current significant improvements.

Storage space, easy and effective disk drive Extender features of Windows Home Server, we recommend that you do not "consumer" versions. However, the blog points out that it is not intended to cover individual features that do not comply with existing extensions of the disk volume.
