“Unlike Phison’s PS5026-E26 controller, which has been in most of the elite PCI Express 5.0 SSDs we have reviewed recently, including the Editors’ Choice-winning Crucial T705, the E31T controller lacks its own dynamic random access memory (DRAM), instead relying on the computer’s host memory buffer (HMB) for caching.
A common concern with DRAM-less SSDs is that their architecture could impact write speeds. The upside is that they tend to consume less power and run cooler than SSDs with their own DRAM cache, and come in at a lower price.”- pcmag.com
