Got 4 x HPE branded Micron 5100 Eco SSDs and 4 x standard Micron 5100 Eco's - all 7.68 TB. I have been testing these and get different results on the LSI2308 vs on a normal Intel SATA port. I've been struggling to find benchmarks for the 5100 Eco's to compare against. What I've found is that there's weird variance in just the 4K performance
Here's Hot Hardware's CDM result of the 5100 Eco for 4K - notice the 4K QD32 speeds are 280/350 MB/sec for R/W ...
Here's the CDM 4K performance for my 5100, running on the latest D0MU841 firmware, on my LSI2308 HBA, with Windows write caching off and the HBA passed through to Windows Server 2019 - the R/W speeds for 4K QD32 are 228/100 MB/sec ...
Here's @Marsh with some CDM results with a 5100Eco 2TB (c.f. https://forums.servethehome.com/ind...0-eco-sata-ssd-250-obo-ebay.29219/post-271664)
His 4KQ1 & 4KQ32 speeds are way higher than mine and in line with HotHardware, but still a bit lower though. And the speeds I see are not just one Micron 5100, it's *both* the HPE and normal Micron drives I have, regardless of firmware.
Does anyone have any experience with Micron on LSI 2308 HBAs? Are there known incompatibilities? Micron support is pretty much useless. Could it be because I am passing the HBA to a Windows Server guest via ESXi passthru? Or is it the HBA itself?
