Review: A Nice External Harddrive - Connected to my macbook pro m5 without a problem and has worked flawlessly. It is very easy to use. At 5 tb's it has great storage amount. I hope it lasts a long time.
Review: Reliable, durable speedy little hard drive - I've been using Western Digital passport drives since way back in 2005. In fact, I still have an old 40? GB that still works - they're pretty durable, but I get a new one every 7-8 years to make sure I don't have one go bad, and to keep up with any technology advancements like USB 3 speeds. This little guy lived up to my expectations; it was fast, it seems just as well-made and durable as prior versions, and the space let me put on all the episodes of bluey (for my kids) and most of the marvel movies as well (also for my kids), and still have some space to stick on some fun comedy and action flicks (... also for my kids, eventually). It's light weight, fast, durable, and what's not to like? It's a great little drive.

## Questions & Answers

**Q: How is it different from other WD drives sold for 99$?**
A: The 99 dollar models transfer on my computer at around 90 MB sec, bought this USB-c model without realizing it was different, only transfers at 35 MB sec on same computer, considerably slower for more money, stay away.

**Q: What cable will I need to get to connect this to a usb3 port?**
A: Requires a USB-C cable.  I purchased one for $10 at my local computer store.

**Q: Can I boot from this drive on a mac?  In other words, is it bootable?**
A: Yes, if you format the drive in Mac native format, and use a clone application like Bombich Carbon Copy Cloner (CCC), the external drive should be bootable on your Mac.   You have to have macOS copied over, for it to be bootable.  You hold down the option key when booting, to get a boot device selection menu during the boot.

**Q: Good to use with a crome pixelbook (chrome os) ?**
A: The short answer is YES. You will need to format the external hard drive  through your files (blue) folder. However, before doing that, connect the external drive to your USB port and try to save a file to the hard drive. If it works fine, then you don't need to reformat. Hope that helps.

The WD 6TB My Passport Ultra for Mac is a high-capacity, portable external hard drive designed for reliable storage and seamless backup. With USB-C and USB 3.1 connectivity, it offers fast transfer speeds and easy plug-and-play use. Built-in backup software, password protection, and ransomware defense keep your files secure, while the sleek silver design complements any Mac setup.
