SanDisk Professional 4TB G-DRIVE PRO - Enterprise-Class Desktop Hard Drive, Thunderbolt 3, USB-C, 7200RPM Ultrastar Drive Inside - SDPH51J-004T-NBAAD

I loved this HDD it is very fast, has thunderbolt and USB-C connectivity and it pretty solid. I love it !

Works perfect out of the box with easy set up. We’ll see as the months go by! Ok, it’s still working great! 4/25/23

Ive had the drive for almost a year and am on my second warranty replacement. The first was because the drive was loud and made noise. On hearing a recording, support agreed to replace it. The second drive was just as loud, but expected, according to support. Now the power plug port is failing. The slightest bump causes the drive to lose power. Im waiting on a replacement. Id avoid this brand of drives, if I were you.

When this drive is seeking it is really Loud (teeth chattering type sound loud). I wouldnt use it in the same room as one in which youre doing audio recording in. Otherwise, it seems to work well, looks good, etc. Basically loses one star because of the loudness.

I love these G drives. However, do not be disappointed to find out later that it’s large capacity requires it to take up on its own 1.5 TB of its 18TB to function and same goes for the 6TB we got for the business it ate up 1 plus TB so that one is 4.6TB or so will be the usable number available for storage. I think in all fairness Sandisk should allocate that usable and necessary programming software and add the space in addition to the 6 TB and 18 TB that are being purchased for use. At the very least a notice to would-be consumers that advises that they will not have the full 6TB or 18TB capacity of storage that are purchasing.

I bought this SanDisk Professional to replace a failing drive. I was able to copy the failing drives data to it and Ive been very pleased with its responsiveness and performance so far. Its quiet and quick, just what I needed for photo and video editing!

I am using this drive with Time Machine on my MacBook Pro and I am very happy with it. Its not super portable but I dont need it to be. Backups are very, very speedy!

I read a couple conflicting reports on this drive. First, there is a fan and it does come on when it is put under any sort of load. It is quite noticeable, so Im not sure if I will keep it yet or not. Second, it does have a second thunderbolt input and I have attached another flash drive to it without problem. As for speed, I need to work with it a little more to get an idea how fast it is. The drive seems well built.

This is a nice drive, but I did have to reformat it -- no big deal. One thing I really appreciated, are the inputs which allow daisy chaining other drives with thunderbolt 3. These drives have gotten so much less expensive than when I bought a 12 T Raid drive. That old one died on me before I could move all my data. Not going to let that happen again.

This is my 5th G external back up... that should say it all ... Love em
