ATTO is one of the oldest hard drive benchmarks that is still used today. ATTO measures transfers across a specific volume length. It measures raw transfer rates for both reads and writes and places the data into graphs that you can easily interpret. The test was run with the default runs of 0.5kb through 8192kb transfer sizes with the total length being 256mb.
With Intel Firmware 02G9:
With Intel Firmware 02HA Before Ever Running TRIM:
With Intel Firmware 02HA After Running TRIM:
Benchmark Results: Before the firmware update the Intel SSD averaged roughly 80MB/s when it came to the write performance. After the firmware update the write performance jumped up to over 100MB/s in 8KB and beyond. Running TRIM didn’t seem to do too much as you can see from the before and after running TRIM screen captures.
