Solid State Drive Benchmark

Tuesday, September 14th, 2010

This seems like a useful tool for anybody who wants to test the speed and performance of a solid state drive.

Benchmarks are largely used to compare the performance of items in standardized tests. In computing, they are often used to compare video cards, processors and hard drive performance. Benchmark results are artificial results, which means that they do not necessarily result in a similar real world scenario.

Still, it sometimes pays to run benchmarks. An example would be to see if the speed that other users of the device get is also the speed of the device purchased. And benchmarks can obviously be used to compare hardware with each other.

Verify that TRIM is Enabled in Windows 7

Tuesday, September 14th, 2010

Here’s a neat trick that can be used to help an aging computer to act young again …

The TRIM command has been designed to counter the performance drops of Solid State Drives over time. TRIM basically allows the operating system to notify the SSD about data blocks that are no longer in use so that they can be wiped.

Before TRIM, SSDs degraded in performance over time due to the way they handle write operations. Some manufacturers countered this with reset tools, which had to be run regularly to keep the performance at an acceptable level. Finally, some added garbage collection to the controller. This basically meant that the data on the drive would be defragmented, or that the TRIM command would be issued based on the findings of the garbage collection.
