Just got a new 6TB World Edition II. Had a previous 2TB World Edition.
Installed perfectly. Striped RAID formatting went perfectly.
Write speeds max out at ~12 MB/sec.
Read speeds max out at ~23 MB/sec.
Both are slow, but it’s weird writing is slower than reading by a factor or two. (File size does not impact ratio).
Connected through Gigabit router to an i7 quad-core iMac. Everything is wired (no wireless).
