The use of steaming functionality on a storage device may be optimized by performing a combination of stream and non-stream writes based on a size of the data being written to a given stream. For example, a method may comprise writing data associated with a plurality of files to a first set of one or more erase blocks, determining that an amount of data associated with a given one of the plurality of files in the first set of one or more erase blocks has reached a threshold, and moving the data associated with the given file from the first set of one or more erase blocks to a stream, the stream comprising a second set of one or more erase blocks on the storage device different from the first set of one or more erase blocks.

Opportunistic use of streams for storing data on a solid state device

A file system is configured to ensure exclusive access by an application to a 'stream' comprising one or more erase blocks on a storage device. The file system may receive, from an application, a request for a stream identifier token, create a file to store one or more stream identifiers associated with the application, send, to the application, a token associated with the file, the token providing access to the one or more stream identifiers by the application, receive, from the application, a request for access to a stream, the request comprising the token, determine that a stream is available, the stream comprising one or more erase blocks on a storage device, send, to the application, a stream identifier associated with the stream, and remove the stream identifier from a pool of available stream identifiers, thereby ensuring exclusive access to the stream by the application.

Guaranteeing stream exclusivity in a multi-tenant environment

In embodiments of adaptive idle timeout for storage devices, a computing device includes a storage device that stores data for read and write access on a rotating media. An operating system of the computing device maintains a device cycle number as an accounting of each time the storage device is powered on-off. The computing device implements a storage device driver that is implemented to obtain the device cycle number of the storage device from the operating system, and determine a projected cycle number over a duration of operational time of the storage device based on the device cycle number. The storage device driver can then determine whether the projected cycle number exceeds a maximum of power on-off cycles within a warranty period of the storage device, and control a frequency of the storage device being powered-off if the projected cycle number exceeds the maximum of power on-off cycles.
