Kingston SSDNow V300 120GB review: best budget SSD currently around

Kingston joins the affordable SSD crowd


Atto Disk Benchmark

The Atto Disk Benchmark reads and writes data blocks of different sizes as quickly as possible to random places on the SSD. We used the 4kB and 1MB tests. The 4kB tests reflect working with very small files, resembling what happens when starting up software. The 1MB test are a best-case scenario for SSDs and indicate what type of performance you can expect when working with large files, such as copying digital photos, MP3s, and films.

Four commands are simultaneously sent to the disks each time. Since the flash chips in SSDs are parallel controlled, smart controllers can execute multiple commands at once. This improves the performance. In real-life, Windows and other software will also simultaneously send multiple commands to the drives.

Please note: Atto Disk Benchmark uses compressible data. Many files - especially program files - are like this. However, files such as digital photos, MP3s, or films are barely compressible or not compressible at all. The AS SSD benchmark on the next page provides a clearer picture.

The performance of the V300 is in line with other SandForce-based SSDs. Except for the 4K test Kingston is faster than the Crucial v4 and Samsung 840.

4k read

4k data blocks are read at 144.8 MB/s, making it the fastest of the SandForce-based 120/128GB SSDs.

4k write

Writing 4k blocks is done at 203.4 MB/s, a bit slower than other SandForce SSDs.

1MB read

Reading 1 MB data blocks is an indicator of the maximum transfer rate in practice, resulting here in 551.6 MB/s.

1MB write

The 1MB write test is an indicator of the maximum possible transfer rate for writing. Again, Atto works with compressible data so it's no surprise that all SandForce SSDs exceed 500 MB/s.
