Document Summary
Most of the digital evidence (that are referred to in a case) that can be recovered will be stored on some form of storage media: hard disks (including solid state disks) Harddiskdrive rotating disk internally, heat up internally, less. Solidstatedrive solid state, no moving parts, memory chips is where data is stored, lower power consumption, smaller format, faster operating, much more expensive for big storage space expensive. Cost vs performance: usb thumb drives (flash drives, external disks, cd/dvd roms, blu rays. Handheld devices (mobiles, tablets, e readers, digital cameras) Networks, clouds: similar principles apply, but we will just focus on computer context. Volatile data is lost when power is disconnected. Storage devices may be locally connected or remote (eg on internet) Volatile: disappears when power is off, local: yes. Ram (working memory of device) holds data while it is being used . Hdd (internal) not volatile, yes local. Errors may arise, which could impair the credibility of evidence.
