@brian , Indeed I have a very similar question.
I have a small home ESXi server that I managed to get hold of - a Dell T430 which has a Dell PERC H730 RAID Adaptor and a 16 bay, 2.5" SAS/SATA enclosure. Currently, there are two small SAS drive as RAID 1 (1TB, mainly for booting vHDD of various VMs), so 14 bays are free. There is also an LSI 9260-8i RAID Adaptor with 4 x 3.5" WD Red drive as RAID 6 although this keeps mucking about on me and I think a drive is failing. This RAID 6 array is around 5TB, although less than 50% full.
The workload for me is general IT labbing. I spin up different VMs to test various different integrations, but also have some general full time running AD workhorse stuff, such as Exchange (although the user count is negligible), a File Server to save data (mainly photos), and a couple of other VMs.
In the first instance, I'm looking to use a couple of the 2.5" slots with some SATA SSDs (around 1TB each I think) as RAID 0, but might well look to increase these over time, so build a redundant array but get good speed, for both boot VMs and to store data.
What I'm interested in is, should there be anything to look out for with the cheaper consumer SSDs (like the Samsung 860) when adding them to RAID controller such as the Dell PERC, and building a RAID array? Is this a no-no, or a viable option?
