I had a Western Digital (WD) EX-4100 RAID-10 network-attached storage (NAS) serve as the backbone for my data storage over the last few years. This week, I upgraded to a Drobo 8D direct-attached storage (DAS) connected to my iMac Pro via Thunderbolt 3. The performance difference is incredible.
Obviously comparing a NAS to a DAS isn’t apples-to-apples, but hey, I have to justify the cost somehow! 😉
I added some Seagate Ironwolf drives to my old WD Red drives from the EX-4100 and a couple Samsung solid-state drives (SSDs) to take advantage of Drobo’s transactional tier with hot data caching. Overall, my “usable” capacity is over 20 terabytes with hot swapping and single disk redundancy (if any one of the drives fails, all of my data is still intact).
Here are some pictures I took as I loaded the Drobo up! 🙂
