I need a FAST BIG external drive for my imac. I’ve been happy with Glyph drives, but am wondering if I just need another 4T Glyph or if there’s something else out there I should know about. I see recommends online for Seagate! (I hate seagate they CRASH). Don’t know which online recommends I can trust. Suggestions? Portability not important. Speed and size are important.
