Paper 1
Revise: Comparing Storage DevicesRead/write speed describes how quickly data can be retrieved or saved. Reading includes loading a saved file; writing includes saving changes to it. SSDs generally read and write faster than HDDs, so files and programs can load more quickly.
Make comparisons explicit: an SSD generally has faster read/write speeds than an HDD, rather than simply saying it is fast.
