“SSDs are a new and evolving (and the SATA versions are already obsolete) technology,” Robin Harris reports for ZDNet. “It’s not surprising that we’re still learning how and where to use them.”
“One of the most popular uses of SSDs is in servers hosting virtual machines,” Harris reports. “The aggregated VMs create the I/O blender effect, which SSDs handle a lot better than disks do.”
Harris reports, “But they’re far from perfect, as a Usenix FAST 15 paper Towards SLO Complying SSDs Through OPS Isolation by Jaeho Kim and Donghee Lee of the University of Seoul and Sam H. Noh of Hongik University points [sic] out: ‘In this paper, we show through empirical evaluation that performance SLOs cannot be satisfied with current commercial SSDs.”‘

MacDailyNews Take: Yes, using an SSD poorly can waste most of its possible performance, but to say they “don’t perform,” as Harris’ headline states, is ludicrous.
