We continue our benchmarks using the OCZ Synapse Cache 64GB SSD as a regular, non-caching solution, without using the DataPlex software.

One of the finest tools available to measure storage performance is ATTO. The tool measures storage systems performance with various transfer sizes and test lengths for reads and writes. The benchmark performs file transfers ranging from 0.5 KB to 8192 KB. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Writing peaked at around 402 MB/s for the 32KB file and reading 567 MB/s for the 8192 KB file. The drive performed great in the reading tests with large files and also in the writing tests with files smaller than 64KB.

Here is a comparison of the OCZ Synapse Cache 64GB SSD with other SSDs:

We proceed to IOMeter benchmark. Iometer is run by using workstation and database patterns for queue depths (outstanding I/Os) of two and 32, representing very light and moderate loads. Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). The app's ability to bombard drives with an escalating number of concurrent IO requests also does a nice job of simulating the sort of demanding multi-user environments that are common in enterprise applications. It can be used for measurement of the performance of an SSD. We run the IOMeter tests using the Xtreme Benchmark template .

With 8003.81 combined IOPS, the Synapse is not the fastest SSD around, but don't forget that it's just a 64GB SSD. Here is where the drive stands compared to other SSDs:

Below you see the results of Futuremark's PCMark 7 Professional edition. The drive scored 3118 points. Below you see the performance of the Synapse SSD in various tasks defined by the software:
