Speedy, small and affordable.
Quick-formatting the drive with NTFS gives me 117GB of usable area under Windows 7. The Kingmax KM21 128GB SATA II SSD was tested on the below system:
Given that this is a SATA II drive, I have decided to select the slightly older Kingston V-Series 60GB SATA II SSD, the WD Caviar Black 2TB 7200rpm SATA III as well as our flagship Kinston HyperX 240GB SATA III SSD.
The PCMark 7 Storage benchmarks are some of the most stressing tests designed for modern hard drives and solid state drives. There are a number of tests performed, focusing on different aspects of the drive and eventually churn out a score based on the overall performance of the drive.
That’s the overall score presented by PCMark 7. Below you can see the breakdown of individual benchmarks with the testing methodology. All the below tests are measure in MBps speeds, rather than the score posted up.
This workload uses a trace of Windows Defender’s Quick scan of the system.
Recording of activity on system drive started just before clicking Quick scan on Windows Defender and lasted until the scan finished.

This workload uses a trace of importing a collection of images in Windows Live Photo Gallery.
A USB stick with 68 images (434 MB total) was inserted and images were imported to Windows Live Photo Gallery. Recording of activity on system drive started at the beginning of importing pictures and lasted until thumbnail images appeared on the display. During the trace Windows Live Photo Gallery copied images from USB stick to Pictures library, indexed them and created thumbnails.

This workload uses a trace of compiling a home video from a set of video clips.
The source videos were shot with a Sony HDR-HC3 and imported to the PC. The source video was 1080i MPEG-2 videos. A home video project was prepared with Windows Live Movie Maker. Recording of activity on system drive started just before clicking Publish (1080p video) and lasted until publishing finished. During the trace Movie Maker read parts of source files and wrote a single output file.

Windows Media Center
This workload uses a trace of Media Center activity.
PC was equipped with a dual DVB-T tuner. A movie was recorded and after the recording had finished, two simultaneous recordings were started and playback of the first movie was started. While maintaining this setup of two movies streaming to storage and one being played back, activity on system drive was recorded for 4 minutes. During the trace Media Center read one file and wrote two others.

This workload uses a trace of adding music to media library.
On another PC, a hard drive was filled with 68 GB of music files (lossless WMA). The hard drive was connected to the PC recording the trace. Windows Media Player was started and the music folder in the new drive was added to Music Library. Recording of activity on system drive started just before adding the folder to Library and lasted until Windows Media Player status bar read “Update Complete”. During the trace Media Player scanned music files on the added hard drive (which is not included in the trace since the activity did not happen in the system drive) and indexed them (which is included in the trace since index files are located in the system drive.)

This workload uses a trace of starting up home and office productivity applications.
PCMark 7 specification 1.0 document was copied to Desktop. The document was opened by double clicking and few seconds later Internet Explorer was started from the toolbar. Recording of activity on system drive started just before double clicking the document and lasted until both applications had started and became responsive. During the trace Windows loaded the executables and related DLLs from the system drive.

This workload uses a trace of starting up World of Warcraft.
World of Warcraft was installed. A new character was created in the game. The game was closed and started again. Recording of activity on system drive started just before logging in the game. Game loaded and the new character was selected as quickly as possible. The recording was stopped right after the game world had loaded so far that the character could move in the world. During the trace the game loaded game data from the system drive.
