Could it be that Micron through OWC is dumping inventory or OWC bought the remaining stock of the S630DC series? If I read the model history correctly, first announced in 2015, shipping in quantity in 2016. Micron's website really only shows SATA and NVME for enterprise products now? The enterprise product catalog does not list the S630DC and am having a tough time finding "front page" listings of SAS SSD's on the Micron website.
For me this actually ticks a lot of boxes for customer deployment vs. purchase for home lab and buying parts of eBay whether for homelab or even customers.
Warranty - granted only 3 year
Reasonable PBW lifetime
Reasonable throughput for mainline general storage and I think even VM's backed by NAS on 10Gbps. 10Gbps may become the bottleneck with medium sized R10 arrays.
S630DC optimized for mixed read/write performance (Micron product release)
Price as noted previously: .12 / GB
