SanDisk Extreme II 120GB SSD Review - Benchmarks - PCMark Vantage - Drives with Data Testing

SanDisk Extreme II 120GB SSD Review

We're starting our SanDisk Extreme II review coverage with the 120GB capacity size. Later today we'll publish reviews of the 240GB and 480GB, but the 120GB size has more talking points and shows why SanDisk now has the most advanced NAND on the market today. (NASDAQ:SNDK)

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

 

SSD's 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. SSD's 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.

Measuring real-world performance with 50% of the NAND capacity full resulted in nearly identical performance to OCZ's Vector. At 75% full, Extreme II was a little faster than the current Vector 120GB, but down slightly to the 840 Pro.
