Transcend SSD320 256GB SSD Review - Benchmarks - PCMark Vantage - Drives with Data Testing

Today Chris follows up the Transcend SSD720 review with the mainstream model, the SSD320. The SSD320 pairs asynchronous flash with the same SandForce controller found in the flagship 720 model. This combination reduces the total cost, but does it also significantly reduce performance?

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.

Using the 50% of total flash capacity taken we get a better look at how a SSD performs in user systems. The async flash really loses a lot of performance in this test and this is the main reason why I dislike seeing asynchronous flash paired with SandForce controllers.

 

Most of the time we see async flash used in thumb drives and other less advanced devices so we have to give credit to SandForce for making a controller that is robust enough to deliver SSD performance with this type of flash. The only problem is the 50% performance is about the same as what you would find on an older generation SF-1200 drive paired with synchronous flash.
