Windows Vista introduced a number of new I/O functions to the Microsoft Windows line of operating systems. They are intended to shorten the time taken to boot the system, improve the responsiveness of the system, and improve the reliability of data storage. I/O subsystem. With the new asynchronous I/O APIs, a thread, different from the one that issued the I/O request, can be notified when the operation completes. With this, a single thread can issue all the I/O requests, and then switch to a different worker thread. If this thread is the one that handles the data after the I/O request completes, then a thread- switch, which causes a performance hit, may be avoided. Windows Vista also introduces synchronous I/O cancellation. During a synchronous I/O request, the application is blocked until the request is serviced or fails. In Windows Vista the application may issue a cancellation request. Applications that cancel the operation on user feedback may prefer to enable user feedback during the time the issuing thread is suspended for usability. Windows Vista also implements I/O scheduling as prioritized I/O. Windows Vista defines five priority classes – Very Low, Low, Normal, High and Critical.
![]() By default I/O requests are assigned Normal priority. Windows Vista also allows reservation of bandwidth on a per- application basis during disk access; this aims to guarantee the required throughput rate to the application when it accesses the disk. Both these features are used by Windows Media Player with respect to media playback. In Windows Vista, there is no limit on the size of I/O requests. This means an entire I/O operation can be completed by issuing fewer requests, which in turn may lead to higher performance. Windows Explorer and the Command Prompt'scopy command have been modified to issue 1 MB requests. When such a device is plugged in, the Windows Autoplay dialog offers an additional option to use it to speed up the system; an additional . The drive- side functionality is expected to be standardized in ATA- 8. When a hybrid hard drive is installed in a Windows Vista machine, the operating system will display a new . It is based on the . It does so by continually analyzing application behavior and usage patterns, e. Although hard disks usually have higher sequential data transfer rates, flash drives can be faster for small files or non- sequential I/O because of their short random seek times. Offline Files. It locally caches shared files marked for offline access, and uses the cached copy whenever the network connection to the remote files is interrupted. Windows Vista Business, Enterprise and Ultimate editions contain significant improvements to Offline Files. Beginning with Windows Vista, whenever the connection is restored, all open file handles to the cached copy are redirected to the remote version, without waiting for the cached files to be synchronized. The local copy is automatically synchronized with the remote copy, to reflect the changes made on either copy of the file. The file caching and sync algorithm has also been completely rewritten to determine the differences faster. When synchronizing the changes in the cached copy to the remote version, the Bitmap Differential Transfer protocol is used so that only the changed blocks in the cached version are transferred. ![]() ![]() This also improves support for caching large files. Sync Center can also report sync errors and resolve sync conflicts. The property page for any file or folder has an Offline Files tab that provides status and allows control of the offline status of the file or folder. Moreover, even if a single file is unavailable, other files in the same share and other shares are available as the transition is now at the share level instead of server level. Offline Files are configurable through Group Policy and provide better interoperability with DFS. Also, a comprehensive Offline Files management API is available via COM objects and scriptability through WMI. Windows Vista also supports . When users make only a few files from a directory available offline, Windows Vista creates ghosted entries of the remaining unavailable items to preserve the online context. Offline Files also feature slow- link mode which when enabled through Group Policy, always reads from and writes to the local cache to improve performance over a slow network connection. It is also possible in Windows Vista to specify a limit for the total size of the local cache and another sub- limit for the space used by automatically cached files. Manually cached files are never removed from the local cache even if the cache limit is reached. In Windows XP, Offline Files could not be enabled when Fast User Switching was enabled. This restriction applied because . In Windows Vista, this restriction no longer applies as Offline Files runs as a Windows service that performs synchronization for the user at opportune times such as logon and offline to online transitions. Synchronization does not occur continuously in the background. Transactional NTFS allows for files and directories to be created, renamed, and deleted atomically. Using a transaction ensures correctness of operation; in a series of file operations (done as a transaction), the operation will be committed if all the operations succeed. In case of any failure, the entire operation will roll back and fail. Shadow Copy. The Backup and Restore Center in Windows Vista and later performs block- based backups when doing full system backups. The file backup feature also uses shadow copy but stores files inside ZIP files. Beginning with Windows Vista, Shadow Copy is also used by the System Protection component which creates and maintains periodic copies of system and user data on the same local volume (similar to the Shadow Copies for Shared Folders feature in Windows Server) but allows it to be locally accessed by System Restore. System Restore allows reverting to an entire previous set of shadow copies called a Restore point. Prior to Windows Vista, System Restore was based on a file- based filter that watched changes for a certain set of file extensions, and then copied files before they were overwritten.
