====== Storage Solution ======

**Single Disk solution**
  * Portable Drive:
    * good up to 5tb each, easy portable, 
    * but if your collection large than 5tb or 2 collection more than 5tb, it is hard to re-arrange and move around between disks
  * 3.5in Portable Drive:
    * need power adapter, bulky, more time for disk spin up to start
    * if multiple drive, need more power socket to plugin

**Multiple Disk Solution**
  * Hard Disk Dock (>2 slot)
    * good to quick swap naked disk
    * most have diskA to diskB standalone disk clone
    * but not physically stable on desk for long time use
  * NAS machine with disk slots 
    * built-in RAID support
    * built-in system to configure share, access control, security, backup
    * more ports like Ethernet ports, usb 3.2 transfer speed.
    * but expensive like a mini pc price
  * DIY machine with RAID supported motherboard
    * DIY guide, basically a PC build and NAS software setup: 
    * ref: Should You Buy or Build a NAS https://www.youtube.com/watch?v=SNY-XAgBEYs
    * good on component choice of upgrade and repair
    * but if you keep your machine on 24/7, you may want to fact in the power consumption cost as well compared to small minified NAS machine

**Cloud Storage**
  * like Google Drive, amazon S3 storage, adobe cloud, other network storage
  * built-in security and backup
  * global accessibility
  * large data maybe trouble to upload and download depending on network
  * but on-going money spending
  * also features is limited to what those cloud service provide gives
