The LaCie d2 Professional gave decent performance for external spinning media and offers massive capacity in a small footprint. Creative professionals that crave a lot of capacity in a slick looking box can't go wrong with the LaCie d2 Professional.
LaCie d2 Professional Review (10TB)
It's TLC from what I recall. Pricing is an issue...ultimately NVMe SSDs will get faster and we'll view this as a transition period I think. Optane is fundamentally different though and it remains to be seen if they can get capacities up. There's also the PMEM issue, and how much speed that enables vs accelerating at the storage drive layer. Fun times.
You're not wrong, but I haven't heard anyone worry about TRIM in years. The drives have become pretty darn reliable. How much data changes on a daily basis or between backups? Two drives means larger workstations, etc. Just wondering what the other logistics are here.
The testing methodology is a little different, we debated putting the 860 EVO on for instance, but it's apples to apples with a bite missing so we opted not to. You could pull the reviews side by side to compare with the understanding the QLC drives are tested more gently.
