LaCie 1big Dock External Hard Drive 4000 GB Black

This was exactly what I wanted. It is easy to use, good quality, and the thing I like the most is that you can put replace the drive inside with another if you so choose.

This drive bricks and Lacie provides to support to solve.

Mixed views. Drive was very good when it worked. Sadly it failed after less than two weeks as unit would not power on. Either power supply or internal power circuitry failed. Have been forced to work through Seagate support services. Initially, customer service was excellent and their Data Recovery Service was excellent, but on June 30, Seagate eliminated any and all telephone support and now only uses web text/chat-based support. NOT efficient and VERY frustrating to use. Seagate promised a quick replacement drive for failed unit, but it's been several weeks and no sign of it as yet.

It comes with Nas Pro drive only. Mac have to connect one port only. The other port can connect to another T2 devices. I had a previous model is much better than this one. Extra c port can connect to iPad and Mac can connect any port.

The fan on my LaCie 1big Dock Thunderbolt 3 4TB HDD and Desktop Hub was not turning on and the top of the case seemed to be getting quite hot after one hour. I decided to return it for a replacement so I did a secure erase. The drive was left on for several hours during this process and after time, the fan eventually turned on. I missed it in the manual (page 22) but the fan is temperature controlled so It will not turn on when you first apply power. The unit needs to be on for a L_O_N_G_ time to generate heat before you will notice any fan activity. I cancelled my return and am quite happy with it. This is a very heavy and well built external HDD and has been working well with TimeMachine for Mac.
