> Interesting! I'd never thought about that. It would be awesome if drives could just seamlessly wake up and start delivering data with no real penalty. Anywhere I can learn more about this or the burst optimization? Is that something anybody in the press is measuring and benchmarking today?
The main burst optimization is SLC write caching, which is universal on client/consumer drives that use TLC NAND flash (three bits per cell), and common on more recent drives that use MLC NAND flash (two bits per cell). M.2 PCIe SSDs also suffer from the thermal constraints of their small form factor and they will throttle under sustained benchmarking, but almost all of them can stay below their thermal limits when subjected to real-world workloads.
As for power management wake-up latency, I'm about halfway through testing my collection, and it'll be a part of my SSD reviews going forward. It's not an issue for desktops because they seldom make use of drive and link power management, but laptops face some serious tradeoffs. I'll make a full article of it over the next few weeks, but I have to finish a few other reviews first. Keep an eye on AnandTech.com next month.
