The document compares the performance specifications of three PCIe flash cards: the LSI Nytro WarpDrive, FusionIO iodrive 2, and VIRI FlashMAX II. It reports their capacity, memory type, throughput speeds, and IOPS for various access patterns both before and after fully fragmenting the drives with data. The FusionIO card showed the highest random read performance, while the VIRI card had the highest random write speeds and capacity. After fragmentation, all cards saw reduced performance but FusionIO maintained a more consistent IOPS.

Virident 采用 2A 双 CPU 数据除以 2≈其他单片性能

5. B．碎片化整个磁盘之后的性能
■ Main show 4K performance. (for OS block size=4096)
■ After filling all space all of PCIE Cards have lower performance
■ FusionIO has a better performance as a lower variation of IOPS
