Fusion-io Validates Groundbreaking Solid-State Storage Performance

At Storage Networking World Fall, Fusion-io, a leading provider of enterprise solid-state storage technology and high-performance I/O solutions, announced the results of an independent lab test which confirm the high-performance claims the company has made of its first product, the ioDrive.

Finisars Medusa Labs, the network and storage test systems provider, independently performed benchmark tests confirming Fusion-ios initial performance claims regarding the ioDrive, a high performance Solid-State Drive (SSD) on a single PCI-Express (PCIe) card. In addition to proving the performance numbers stated by Fusion-io, Medusa Labs was also able to independently confirm performance in excess of initial Fusion-io claims by thousands of input/output transactions per second (IOPS) using the Medusa Labs Test Tool Suite.

We are excited to be working with Fusion-io and validating the performance of the ioDrive, said Nick Kriczky, director of Finisars Medusa Labs. Through our validation and Test Tool Suite, we have been able to determine that Fusion-io has met and exceeded their performance claims for their product.

By achieving these incredible transaction rates, and exceeding the performance claims of any other single solid-state drive, Fusion-io stakes a powerful claim as the worlds fastest SSD, putting it in league with proprietary solid state storage appliances and multi-rack SANs that use highly-tuned disk drives to achieve this type of sustained performance.

In addition to validating our initial assertions about the performance we can achieve from a single ioDrive, these tests also confirm that we have exceeded these claims, said David Flynn, CTO of Fusion-io. With one ioDrive unlike appliance vendors who claim their external rack-mounted box is a drive we topped 100,000 IOPS read and 90,000 IOPS write speeds. When you RAID multiple ioDrives together, you can scale beyond anything else available today, as demonstrated through Project Quicksilver, which used our ioDrives to easily achieve over 1,000,000 IOPS.

The tests confirmed Fusion-ios assertion that the SSD performs on the order of 700-Megabytes per second (MB/s) read and 600-MB/s write, IOPS on the order of 100,000 4-Kilobyte (kB) random reads per second and 120,000 1-kB random reads per second. Fusion-ios claims were greatly exceeded in further testing, establishing the company as one of the undisputed market leaders in solid state storage.

Testing Results:

Industry standard Linux benchmark Iozone testing:

Large 64-K packets

  • 730 MB/s random read
  • 630 MB/s random write

4-K packets, random

  • IOPS in excess of 102,000 reads per second
  • IOPS in excess of 101,000 writes per second

1-kB packet, random

  • IOPS in excess of 140,000 reads per second
  • IOPS in excess of 115,000 writes per second

Medusa Labs Test Tool Suite proprietary testing software:

4-K or smaller packets, sequential

  • 141,000 IOPS for read
  • 110,000 IOPS for write

50/50 mix reads and writes on 4-K or smaller packets, sequential

  • More than 101,000 IOPS



Founded in 2006 and headquartered in Salt Lake City, Utah, Fusion-io ( is a leading provider of enterprise solid-state technology and high-performance I/O solutions that unlock a world of possibilities for performance-starved applications, closing the gap between processing power and storage performance.

The increasing demand for a next generation solid state storage technology is driven by advancements in computer processors which, following Moore's Law, have grown exponentially in performance. Mechanical disks, on the other hand, follow Newtonian Dynamics and experience lackluster performance improvements, introducing a performance gap. Ushering in a new era of silicon-based storage, Fusion-io offers several magnitudes of breakthrough performance at a fraction of the cost of today's traditional disk-based storage systems. The companys ioMemory architecture creates a new tier in the memory hierarchy - one that has 100 times the capacity density and 10 times the capacity per dollar of DRAM. NAND flash-based ioMemory makes it possible to have terabytes of near-memory-speed storage within each node bringing extremely large memory problems and I/O bound analysis to a new level of cost effectiveness.
