Not 100% sure if this is a good deal or not, or how low the seller will go in BO, but sharing in case someone here can benefit.
If I understood correctly, these are 16GB DRAM based drives with an 8x PCI-E 3.0 interface and an ultra-capacitor + mini-SSD for power-loss handling.
I believe they would be nice for write-caches (ZIL/SLOG), given that this page indicates they should support 10M IOPS in direct-memory-mode and 1M IOPS in block-mode (Seems like it's up to you to configure a bunch of parameters that trade-off latency and throughput by changing the block-size, queue-depth, etc. - they show two extreme examples: a 5.1GB/s throughput with 320K IOPS and a 773uS latency and another extreme at 23MB/s throughput with 46K IOPS and 16uS latency).
Drives:
Microsemi NV-1616 EMC 16GB DDR MN NVRAM 1616 Card @ $295 OBO
Capacitor modules:
Microsemi SCM-F100 5.4V 100F @ $35
