Data Transfer Notes

Lessons learned from transferring roughly 14TB of data onto four 4TB HDs.

• Avoid direct data transfers across mixed platforms using hardware solutions
• Use NTFS as the common file system across mixed OS environment
• Use Windows to format exFAT volumes
• Don’t let Windows touch a Mac or Linux formatted exFAT volume
• It takes roughly 3 hours to transfer 1TB over USB 3.0 from HFS+ to exFAT using a HD caddy
• Create a data transfer plan before you start the process
