For both, I was looking at 1.6TB. Also, yes, I agree, I could've bought more Micron devices (he had two more). However, the big determining factor for me was the condition. The 3608s have years of warranty left and were essentially brand new, never used open box items. The Microns were heavily used with 1 year of warranty left (and I've had problems getting a Micron RMA'd in the past even basically being brand new). That beind said... I mean...does it really matter with the endurance of these drives? Not that much...but I still felt like I was getting a better value with unused 3608s. Besides...4 of either device is more than I will likely ever need. In my opinion, the 3608s are some of the best NVMe ever made, so getting them at the price and condition I did, I was fairly happy. While I'm glad to have the warranties, I've built a number of high end clusters using Intel P series devices (lots of 3xxx) and we have only had a single failure and that was because the client reduced their airflow to a minimum (...to reduce power costs
...wasn't the only problem they had). Despite that, Intel was glad to replace it, almost seemed too easy.
Either way, it was hard to spend that much over the Microns, but I think in the long run, I'll be happy I did.
Now...on to GPU
although that decision should be fairly easy.
