Whats the different between this and a regular hybrid SSD/HDD besides being more expensive and exclusive to Intel? No benchmarks and pretty bad write speeds(even if latency is low). I bet this would get beat by a SSD/HHD hybrid for a lot less money.
Queue depth is being hyped but means basically nothing for commercial SSD's that have battery backed ram cache. The SSD just queues writes until queue depth is deep enough.
- endorphone 9y agoMost SSHDs offer 8GB of flash storage max, and often post numbers that indicate that the flash storage is mediocre. This will absolutely annihilate the vast majority (or all) SSHDs. Is it really so much more expensive? $44 for 32GB of high speed caching is impressive. Extraordinarily few SSDs, even commercial, have battery backed caches (and those that do often turn into a reliability nightmare), and when they do it tends to be relatively tiny compared to the scope. Queue depth is profoundly important in the real world.

- wbkang 9y agoOne more thing is that every single SSHD ran @ 5400rpm. I ended up buying a conventional HDD @ 7200rpm and bundled a portion of my SSD with PrimoCache.
- kijin 9y agoYeah, the SSHD offerings from Seagate et al. are atrocious. It's almost as if they don't want to sell them. Perhaps they're afraid of cannibalizing other product lines?
- Dylan16807 9y agoFrom what I remember a lot of them don't even use the flash to speed up writes, throwing away a lot of the potential performance gains.
