Check out our explainer to learn more about the benefits of RAID and the details of each of these configurations.

The Pegasus RAID engine, which you access through the software utility, can also configure the drive to use RAID 0, 1, 6, or 10 setups.

It's more redundant than a RAID 0 configuration and faster than a RAID 1 configuration, but it means you won't be able to use the full 12TB of space (instead, you're limited to 9TB). The default configuration is a RAID 5 array, which distributes data across the four drives in such a way that it's all accessible even if one drive fails. An unsynchronized logical drive could result in reduced performance.

It's a good idea to install the software even if you don't plan on changing any settings, since it displays the status of the RAID's logical drive synchronization, which starts automatically but took nearly an hour to complete on our review unit. Promise also sells a Windows version of the drive that's preformatted for the NTFS file system.
Likewise, if you bought the Mac version of the drive (which comes preformatted for the HFS+ file system) and need to connect it to a Windows machine, you'll need to download the Windows version of the software to reformat the drives. But if you'd like to reconfigure the RAID settings or access any other advanced features, you'll need to download the latest version of the Pegasus software utility from the company's website. If you're just planning on using it to boost storage for your Mac, there's no software setup required all you need to do is plug it in and the computer will instantly recognize it. Setup can be very simple or relatively complicated, depending on your plans for the drive.

Finally, the second Thunderbolt 3 port comes in handy if you have additional peripherals but your MacBook Pro is short on available ports the Pegasus3 can daisy-chain up to six devices. Since the Pegasus3 includes an internal power supply, there's no bulky AC adapter to deal with. The lock slot makes it harder to steal the enclosure, but a thief interested in your data can easily remove the drives from the front. The rear of the enclosure is also home to the power port, two Thunderbolt 3 connectors, and a Kensington lock slot.

During testing, the fan noise was audible-but not annoying-even in the crowded and noisy PC Labs. Around the back, you'll find not one, but two exhaust outlets to handle the copious amount of heat that five spinning disks generate. The front also includes the power button, although you won't need to press it since the Pegasus3 automatically turns on whenever you plug the Thunderbolt 3 cable into your Mac. You can disengage the locking mechanism for each one and remove the drive sleds without any tools, which will come in handy if you plan to use the drive in the "Just a Bunch of Disks" (JBOD) configuration and frequently hot-swap them. The front of the enclosure features the drive access doors. The reason for the short length is that Thunderbolt 3 connections are still quite expensive you won't find a high-quality one that's longer than 3 feet online for much less than $30. Promise includes one that measures about 3 feet long, which is small but longer than the sub-1 foot cables that you'll often find bundled with hard drives. Hiding the enclosure under your desk or in a server closet would do wonders for your office aesthetic, but unfortunately you're limited by the length of the Thunderbolt 3 cable. They're housed in a bulky, black, rectangular enclosure that measures 7.5 by 7.3 by 9.6 (HWD) and weighs 15 pounds. There are also 24TB and 48TB versions that cost up to $5,000. We tested the entry-level Mac-specific Pegasus3 R4, which costs $1,499 and features four 3TB drives spinning at 7,200RPM. Video editors and others with mountains of often-accessed data will find them to be a worthwhile investment. And, by combining multiple spinning drives into RAID arrays that connect to your Mac or PC via a Thunderbolt 3 cable, they offer comparable throughput to an SSD.
While the Promise Pegasus3 line of drives certainly aren't cheap (the 12TB version we tested costs $1,499), they pack in way more storage than you're going to see in a consumer-grade SSD.
Solid-state drives (SSDs) read and write data much quicker than conventional spinning drives, but their high cost keeps their storage size on the low side. For most consumers, shopping for an external hard drive involves trading speed for storage capacity.
