Paper 1
Revise: Comparing Storage DevicesExamples include magnetic hard disk drives (HDDs), solid-state drives (SSDs) and optical discs such as CDs, DVDs and Blu-rays.
Make comparisons explicit: an SSD generally has faster read/write speeds than an HDD, rather than simply saying it is fast.
Avoid absolute claims such as ‘SSDs cannot break’ or ‘HDDs cannot be transported’. Compare their relative strengths and weaknesses.
