Samsung 840 500GB SSD Review - Benchmarks - PCMark Vantage - Drives with Data Testing

A number of next-generation SSDs are coming to TweakTown this week. OCZ, Intel and Samsung and others will follow after CES. Today Chris tests Samsung's low-cost 840 with TLC flash in the 500GB capacity size. Does TLC show the love or is this low-cost offering another low-budget blunder?

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.

The Data on Disk Tests were another area the Samsung 830 had a difficult time. The 500GB 840 does much better than the 830, but it's still slower than the Team SandForce drives and the Crucial m4 512GB.
