Systems and methods for predictive performance indicators for storage devices are described. The data storage device may process host storage operations and maintenance operations that impact real-time performance. A performance value and corresponding threshold may be determined. Increases in maintenance operations and resulting changes in the performance value may be predicted. When the predicted change in performance value crosses the performance threshold, the host device may be notified.

Predictive performance indicator for storage devices

A memory card is provided with various pad layouts to prevent a data signal pad from contacting a power contact in a host during insertion and removal of the memory card. The memory card can have a form factor and features that accommodate a relatively-large memory with relatively-high performance and accompanying thermal conditions. An efficient card lock mechanism is also provided.

Systems and methods data storage device performance prediction based on garbage collection resources are described. The data storage device may process host storage operations and determine a valid fragment count parameter for a current or future data block. Based on the valid fragment count parameter a predicted performance value for host storage operations is determined and the host device is notified of the predicted performance value.

A socket includes a housing configured to receive a removable Data Storage Device (DSD) and a Thermal Interface Material (TIM). An assembly of the socket is attached to the housing and configured to expand due to heat. In a thermally expanded state, the assembly causes the TIM to come into contact with the removable DSD to draw heat away from the removable DSD. According to another aspect, a retaining strip or assembly is attached to a housing in a configuration such that the retaining strip or assembly expands due to heat to increase a resistance to removal of the removable DSD from the housing when the retaining strip or assembly is in a thermally expanded state.

Sockets for removable data storage devices

A system and method are disclosed for an event lock storage device. The storage device includes a user partition and an event partition (which may be associated with an event). The storage device receives data from a host device, and stores the data in the user partition. In response to receiving an indication of an event, the storage device may designate the data as part of the event partition. The event partition may include a set of access rules that is different from the user partition, such as more restrictive rules for modification or deletion of a file containing the data.
