OK for general data but not good for video editing.
I received the drive and connected to my MacBook Pro in to Thunderbolt port. But the drive was not detected. Only works through a USB cable only. I raised a complaint with Scandisk but no help provided. The drive stalls during video playback. So use for normal data only. Not good for video editing.

Excelente calidad
Viene con todos los cables que puedes requerir para usarlo en tu computadora. Yo compré 2 discos para configurar una opción de RAID 1 y usarlo como disco de trabajo cotidiano en una Mac, es una buena opción por si consideras comprar un arreglo de discos dedicado con configuración de fábrica tipo RAID 1, considera que tú mismo puedes usar 2 discos y vía instrucciones sencillas en el sistema operativo de Mac puedes hacer tu propia configuración RAID 1.

A Fantastic Drive for Video Editing
I don't often write reviews but feel compelled to do so. I'm a creative professional and I use an insane amount of hard drive space. A large part of my business involves a video editing workflow. I'm partial to SSD's as they are the fastest, but they are too expensive per gig. So I took a chance on this drive and I am extremely happy. I've been editing large HD video projects with ease. Fast, efficient, no waiting. I'm very please and will be buying more of these drives in the future.For reference, I run Final Cut Pro - MacBook Pro 16" base model.

Solid drive as expected
Housing build quality is good as expected. Power cable/brick cord is definitely fairly stiff so I worry about long term durability if this drive is moved around. I’ve been using this drive for photo storage, no complains on speed/usability on my MBP16, sure it’s not as fast as SSD but it’s not detrimental to workflow. As other reviews mention, a large amount of advertised space is lost through the formatting on this drive. Comes with power supply and USB-C cable. I’d definitely purchase this drive again if looking for a non-redundant directly attached large capacity storage device.

Good drive as a Time Machine
Nice solid drive, strong metal case, speed as described, formatted to use with Apple computers out of the box. Have faith it is built last a long time.

A Little Pricey for a 4TB External HDD, but you'll like how robust it appears to be.
I loved that this external HDD was already formatted for my iMac. So, I just had to connect it, turn it on and use it right out of the box.It's a little noisy when it's working, but that's a minor thing to me. At least I know it's doing something when it starts chugging along.I hope it lasts longer than the WD external HDD it's replacing and that it proves to be worth the premium price I paid.
