Pros: NO RAID Real HBA PCI Gen 3 Works awesome with Windows Storage Spaces
Cons: cost?
Overall Review: I'm using this on my whitebox hypervisor. Since ESX doesn't let you do anything with storage system i decided to use hyper-v and windows storage spaces. My storage space is a combo of ssd and hhd which is called a "tiered pool". With a TP windows puts the "hot" files on SSD and "cold" on HHD. I've also configured each volume with its own SSD write cache (storage space parameter). Result: Super fast VMs. No disk contention, no exhausted disk caches, no more lengthy disk queues. This is a great freaken product.
