OCZ Technology Vector 150 120GB SSD Review

Vector 150 120GB comes with 128GB of NAND flash. Overprovisioning moves the user capacity down to 120GB, but steady state performance gets a boost. (NASDAQ:OCZ)

PCMark Vantage - Drives with Data Testing

 

For a complete breakdown on the Drives with Data Testing please read this article. You will be able to perform this test at home with the files provided in the article - full instructions are included.

 

- Brief Methodology

 

SSDs perform differently when used for a period of time and when data is already present on the drive. The purpose of the Drives with Data testing is to show how a drive performs in these 'dirty' states. SSDs also need time to recover, either with TRIM or onboard garbage collection methods.

 

Drives with Data Testing - 25%, 50%, 75% Full States and Dirty / Empty Test

Files needed for 60 (64GB), 120 (128GB), 240 (256GB)

60GB Fill - 15GB, 30GB, 45GB

120GB Fill - 30GB, 60GB, 90GB

240GB Fill - 60GB, 120GB, 160GB

Empty but Dirty - a test run just after the fill tests and shows if a drive needs time to recover or if performance is instantly restored.

SSDs slow as data populates the flash. In this test, we see performance at different stages of the flash filled with data.

 

We use the 50% full marker to evaluate performance. Vector 150 is a bit faster than the original Vector when half full, but both are a little slower than 840 Pro 128GB.
