ioDrive Duo

ioDrive DuoThe ioDrive Duo is logically a successor to the original ioDrive and predecessor to the ioDrive Octal. All are part of an enterprise-class series of PCI-Express x4/x8 or PCI Express 2.0 x4-based SSDs from Fusion-io. As the name implies it doubles the storage density and performance over the first ioDrive, and consists several capacities, utilizing both SLC and MLC NAND flash modules. Fusion-io stresses that this is “not an SSD”, but something much more and that it outperforms dozens of SSDs on a single server.

Performance figures are indeed impressive. In addition to improved durability, the two SLC-based drives (320GB and 640GB) offer a read and write bandwidth of 1.5GB/s. Read and write IOPS differs slightly between the different capacities but both exceed 250,000 IOPS. The MLC-based drives, available in 640GB and 1.28TB capacities provide the same read bandwidth as its SLC counterparts but somewhat slower write bandwidth 1.0GB/s for the 640GB model and 1.1GB/s for the 1.28TB. Similarly, read and write IOPS numbers are somewhat lower than in the SLC drives.
