OCZ Agility EX 60GB SSD

When looking at the PostgreSQL performance, to no surprise the Agility EX drive was the best performer by far. The Agility EX was capable of handling more than 2,900 transactions per second with this demanding real-world test where the former Agility was at just over 1,000 TPS and the Vertex not even at 600 TPS. The Seagate SATA 2.0 HDD here though actually came in second place for its performance with PostgreSQL database operations.

When it came to using the Threaded I/O Tester to measure the latency during random writes with 32 threads of 256MB writes, the Agility EX actually was not the best performer but rather the worse. The OCZ Vertex actually had the best performance, but it was just an 11 microsecond difference between the best and worst performing drives and with this being a synthetic test, it carries little weight.

When switching to random reads of 256MB x 32 threads, the latency was the lowest with the Agility EX. The 60GB SLC SSD had a latency here of 3794 ms compared to 3832 ms with the non-EX Agility and then 4156 ms for the Vertex.
