7-Way SSD Round-Up: Sandforce vs. JMicron

Article Index

Test System and IOMeter

Our Test MethodologiesUnder each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations.  The SSDs were left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO, Vantage, and CrystalDiskMark benchmark tests. And all drives were secure erased prior to the start of any testing. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system and waited several minutes for drive activity to settle before invoking a test.

IOMeter
I/O Subsystem Measurement

In the following tables, we're showing two sets of access patterns with IOMeter; one with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and one with IOMeter's default access pattern of 2K transfers, 67% reads and 100% random access. Both tests were conducted with 8 worker threades. 

Our IOMeter testing shows a huge disparity in performance between the JMicron based Patriot Zephyr and SandForce based drives. The Zephyr offers only a fraction of the performance of the other drives with the access patterns we used with IOMeter. The SandForce based drives, however, were tightly grouped, with the OCZ Vertex 2 100GB technically coming out on top by the slightest of margins.

The updated 120GB Sandforce drives perform somewhat lower than their 100GB counterparts, however.
