Disk Utility Partition Existing External Hard Drive

I had a support chat with OWC first before ordering this because of the cost involved. Wanted to be sure that I was sure that it would work with my 2019 Mac Pro. They assured me it would, so I ordered confidently. Installation was simper than simple, just lift the top, place the card in a slot, replace the top, boom. Booted, holding my breath, and it showed up in the disk utility. But showed only 8.64GB of available storage. I tried the Erase (initialize) option, Still 8.64GB. Then, went into the partition setup of the disk utility, and voila, there it showed the full 4TB (well, 3.84TB) storage. Once I claimed it all for a single large partition and then reinitialized the drive (using MacOS Extended, Journaled), all was well. I was then able to make full use of the drive. It seems funny to call it a drive, when it's actually just a thin chip on a PCIE-card. Even what you see in the picture there isn't really it. Most of that bulge is just heat sink. Amazing they can stuff that much storage onto something so small. Also a rather amazing amount to pay for a drive, but I wanted fast, non-internal storage, and lots of it, so felt the need and went for it. So far, it is behaving perfectly, is indeed fast. So after a few anxious 8GB moments, I'm relieved and happy.

I use it for my Mac. I had to work at it to get FileVault to work with it on El Capitan - you need to reformat (no problem) and then partition, for which you need to go to the command line Disk Utility now. Not hard, just that Apple seems to want to dumb down the graphical Disk Utility. If you don't care about that, it works straight out of the box.

Using the Mac Disk Utility, I was able to easily create both a Mac and a Windows partition to back-up raw footage and other video files. I always trust Western Digital and this product will probably not let me down either. It's sleek, quiet, and extremely fast with the USB 3.0. Would definitely recommend to anyone!

I just added the WD 4TB Elements External Desktop Hard Disk Drive to my� back up solution (6 hard drives) and Windows 10.� I disconnected the power and USB cable from a full WD hard drive and replaced it with this new drive and fired it up. It works great, just like I would expect from Western Digital.

Wow, I love this hard drive. It is soooooo much faster than a regular old external drive with a spinning disk. I will be able to use this with my base model M1 Mac Mini. I can't wait!

This external hard drive works really nice and quiet, and it saves lots of disk space on my laptop. The price for it is also reasonable.

This external hard disk drive stores a ton and is light and portable. Great for video on the go editing.

eSata works good for an external disk drive.

Upgraded to faster m.2 drive and got this to clone existing drive and utilize it as fast external hard drive. Works great. Get speeds around 1000mb/s

I like how the drive could be partition
