OCZ Technology Agility 4 256GB Solid State Drive Review - Benchmarks - PCMark Vantage - Drives with Data Testing

At less than $1 per GB right out of the gate, this OCZ SSD is already a making waves, but can it still float after Chris gets finished with it?

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.

As if the initial performance wasn't bad enough, the OCZ Agility 4 256GB loses performance when data is on the drive. This isn't anything new; nearly all SSDs lose performance when data piles up on the flash (other than the Corsair Performance 3). The Agility 4 does not lose as much performance as many other drives, but the loss is still there.

 

The OCZ Agility 4 does do a really good job with TRIM as you can see here. Our sample recovered very well and delivered the same amount of performance as we started with before adding large amounts of data to the drive.
