Stat: Single layer Blu-ray discs max out at 50 GB capacity.
6. External HDDs/SSDs
External drives like portable hard drives and SSDs add considerable plug-and-play storage capacity via USB, Thunderbolt, etc. without opening up devices.
Stat: WD’s MyBook Duo can configure up to 28TB of desktop RAID storage.
7. Magnetic Tapes
Though an older medium, magnetic tapes provide very reliable and scalable backup/archival options still used by data centers and enterprises today.
Stat: LTO-8 tapes store up to 30 TB (compressed) each and have a 30-year shelf life.
8. Cloud/Online Storage
Cloud storage leverages remote servers accessed online to store files and media via services like Dropbox, Google One, iCloud, and OneDrive. It offers convenience but not direct access.
Stat: IBM has provided up to 120 EB of total cloud storage for enterprises.
9. Network-Attached Storage (NAS)
NAS devices are dedicated file storage servers connected via a local network, often with built-in RAID and backup capabilities along with large HDD capacities.
Stat: Synology offers 80 bay NAS units supporting over 1,100 TB of storage potential.
10. Personal Video Recorders (PVRs)
