HDD or SSD?
> As SSDs do not need to spin or seek to locate data, they may prove vastly superior to HDDs in such tests. However, SSDs have challenges with mixed reads and writes, and their performance may degrade over time.

Насколько сильно и быстро degrade?
>Field failure rates indicate that SSDs are significantly more reliable than HDDs, however SSDs are uniquely sensitive to sudden power interruption, resulting in aborted writes or even cases of the complete loss of the drive.

Но у ноутов не должно быть sudden power interruptions, у них же встроенные аккумуляторы...
