MyDigitalSSD BP4 2.5-inch 240GB SSD Review - Benchmarks - PCMark Vantage - Drives with Data Testing

MyDigitalSSD BP4 2.5-inch 240GB SSD Review

Always on the cutting edge of flash technology, leading the capacity vs. price ration, MyDigitalSSD is back with a new, faster Bullet Proof. BP4 uses new Toshiba Toggle 2 NAND with 16K page sizes for higher performance and the new over-provisioning increases random 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.

SSDs slow when the flash has data on it already and in this test we see show how much performance is lost. The BP4 takes a significant hit when you fill the drive half-full. This is the one area where we feel Phison didn't focus enough on with the new programming and firmware.
