LaCie d2 Professional Reviews

These drives just keep on working!

By Richard
Rated 5 out of 5

I have used LaCie drives for a decade or more. They have always done the job. They're quiet and do not run hot. I use two with my Mac Mini, one for Time Machine 8tb and one for Photos 4tb. They do require more power at startup than SSD drives, so be aware of that.

Surprisingly Slow

I bought this drive to replace a 24TB Seagate drive that literally crashed (it fell off my desk and broke). That Seagate drive utilized a USB-A 3.0 connection so I figured this LaCie drive, with its USB-C 3.2 connection, would be at least as fast. Wrong. In hindsight, perhaps the limiting factor is something like the write speed, as opposed to the USB connection. While my old Seagate drive copied data at approximately 250 MB/s, this LaCie drive performs more around 180-200 MB/s. The difference is no big deal for small tasks, but large tasks take significantly longer than they did with my old drive. The LaCie drive also has an external blue light that brightly blinks. If that light serves some function, its purpose is escaping me. The blinking is kind of annoying so I turned the drive around so the light is less in my face. Overall, the drive works, but its performance is very disappointing, and I wish I had bought something else.

is the 8TB a thunderbolt 2 or thunderbolt 3?

is the 8TB a thunderbolt 2 or thunderbolt 3?
Asked by: Jimmy
The 8TB drive is neither TB2 or TB3, but it is compatible with TB3 ports and cables. Spinning hard drives are innately far slower than type C or Thunderbolt 3 cables or ports are capable of. Mega bytes vs Giga Bytes. So the whole thing is mute.
