Conclusion

WinBench 99 2.0 is getting a little too old, at least in the High-End WinBench test. Yet, it continues to give us a lot of interesting data. If the Business and High-End simulations were not good enough, the raw transfer rate results were certainly most useful. From the transfer rate results, you can see which solid state drive had a higher transfer rate.

Of course, solid state drives are a completely different ballgame than hard disk drives. The spatial locality of the data has absolutely no effect on the transfer rate, so you get a constant transfer rate across the entire device. Due to the lack of moving parts, they have very, very low latency which gives them a huge performance advantage in random accesses.

Here is a summary of the fastest and slowest SSDs in the different tests we ran. However, you should never buy SSDs based merely on a simple summary like this, or even on their performance characteristics. There are other factors to consider like storage capacity, power consumption, thermal output and warranty. It's best to read up on the full reviews before deciding on the best SSD for your needs.

We have just 12 solid state drives in this comparison, but you can count on us to continuously improve this guide by adding more solid state drives. However, this depends greatly on our resources which are limited to begin with. So, if you have a solid state drive you no longer use, you can help us by loaning or donating it to us for our tests.

Date Revision Revision History
27-06-2011 3.1

Added the 240 GB Intel 520 Series SSD.

10-05-2011 3.0

Major revamp of the article, with numerous updates and corrections.
Added the Intel X25-M G2 (34 nm) 120 GB solid state drive.
Added the OCZ Enyo 64 GB portable solid state drive.
Removed the Intel X25-M (50 nm) 80 GB solid state drive.
Upgraded to the newer IO Meter 2008 benchmark with tests aligned at 4 KB.
