Storage

• The common term “hard-drive” may refer to actual hard-drives (HDD) or solid-state drives (SSD)

  • Hard drives use spinning disks
  • Solid state drives use magic
    • A certain amount of voltage is applied or removed to/from each memory cell

• HDDs usually provide more storage at a lower cost than SSDs, but are much slower

• Storage isn’t as important to R since data is loaded in memory

  • It can still impact data import/export and other similar tasks
  • Write speeds are usually slower than read speeds

• Similarly to RAM, running to close to full can cause slowness
