Western Digital G-RAID Mirror 48TB review
Explore our hands-on review of the Western Digital G-RAID Mirror 48TB, testing its performance, RAID protection and Thunderbolt 3 connectivity
At a glance
Western Digital’s G-RAID Mirror is a serious upgrade from the 24TB G-Drive we tested recently. Built around the same premium aluminium chassis, it houses two enterprise-grade Ultrastar 7200rpm HDDs and comes configured in RAID 1 for instant data protection.
PROS: Robust build, RAID 1 data protection, quiet operation
CONS: Very expensive, large

What are the key features of the Western Digital G-RAID Mirror 48TB?
Connectivity
Connectivity’s taken a step forward, with dual 40Gbps Thunderbolt 3 ports that support daisy-chaining and full backward compatibility with USB-C systems. There’s also a front slot for Sandisk Pro-Blade SSD Mags, offering up to 4TB of fast, removable storage, which is ideal for quick offloads.
Performance
Performance is excellent. In RAID 1, read/write speeds reach 260/250MB/s, while RAID 0 or JBOD mode doubles that to around 500MB/s. For most users, RAID 1 offers the best balance as every file is mirrored for instant redundancy, giving peace of mind for valuable work.
The G-RAID runs whisper-quiet, stays cool and, in our standard tests, transferred 50GB of images in just over three minutes.
Set-up
Set-up couldn’t be simpler. It’s formatted for Mac and, once connected via the included Thunderbolt cable, it mounts immediately – no drivers or configuration required. It can also be reformatted for Windows.
Conclusion
It’s not the cheapest way to get 48TB of RAID 1 desktop storage, but with its build quality, speed and reliability, the G-RAID Mirror is a professional solution. If you want secure, high-performance storage with room to grow, this won’t let you down.
