Abstract

Systems and methods for reducing problems and disadvantages associated with protecting data during cold excursions are provided. A method for preventing unreliable data operations at cold temperatures may include determining whether a first temperature of a solid state drive (SSD) is below a threshold temperature. The method may also include initiating an artificial read/write operation if the first temperature is below the threshold temperature.

Claims

1. A method for preventing unreliable data operations at cold temperatures comprising:

determining whether a first temperature of a solid state drive (SSD) is below a threshold temperature;

initiating an artificial read/write operation on the SSD to increase the first temperature if the first temperature is below the threshold temperature;

sampling a second temperature of the SSD; and

pausing a read/write operation of the SSD if the second temperature of the SSD is below the threshold temperature.

2. The method of claim 1, wherein sampling a second temperature of the SSD is completed following a pre-defined time interval.

3. The method of claim 1, further comprising proceeding with the read/write operation if the second temperature of the SSD is above the threshold temperature.

4. The method of claim 1, wherein the artificial read/write operation comprises a plurality of SSD controller transactions.

5. The method of claim 1, wherein the threshold temperature is provided by a user.

6. The method of claim 2, wherein the pre-defined time interval is based on an event.

7. The method of claim 2, wherein the pre-defined time interval is provided by a user.

8. An information handling system comprising:

a processor;

a solid state drive (SSD) communicatively coupled to the processor; and

a computer-readable medium communicatively coupled to the processor and having stored thereon instructions configured to, when executed by the processor;

determine whether a first temperature of the SSD is below a threshold temperature;

initiate an artificial read/write operation on the SSD to increase the first temperature if the first temperature is below the threshold temperature;

sample a second temperature of the SSD; and

pause a read/write operation of the SSD if the second temperature of the SSD is below the threshold temperature.

9. The system of claim 8, wherein sampling a second temperature of the SSD is completed following a pre-defined time interval.

10. The system of claim 8, wherein the instructions are further configured to proceed with the read/write operation if the second temperature of the SSD is above the threshold temperature.

11. The system of claim 8, wherein the artificial read/write operation comprises a plurality of SSD controller transactions.

12. The system of claim 8, wherein the threshold temperature is provided by a user.

13. The system of claim 9, wherein the pre-defined time interval is based on an event.

14. The system of claim 9, wherein the pre-defined time interval is provided by a user.
