T-Force Delta RGB SSD Review (Page 2)

1TB Class Performance Testing

Product Comparison


We're testing the Team Group T-Force Delta RGB 1TB SSD today against the current, and a few previous generation popular drives.

Sequential Read Performance


The chart shows that all of the drives perform well with sequential data reads using large block size data. The Delta RGB does trail the others at QD1 (Queue Depth), but it quickly joins the others.

Sequential Write Performance


The sequential write performance is also high for all of the drives, but this is where we start to see the 32L flash start to show signs of weakness. At QD2, the Delta RGB falls to the bottom of the performance list. It only trails by a few megabytes per second with 100% data writes.

Sustained Sequential Write Performance


The Delta RGB uses an SLC buffer to tame the TLC by keeping data writes coming in at high speeds. There is a slight performance drop after the SLC buffer. The drop off is much smaller with this product than the other models we tested when 32L TLC first came to market from Micron.

Random Read Performance


Random read performance has not improved much from the early 32L drives we tested. The Delta RGB only manages 7,000 random read IOPS at QD1. This is one of the most important areas for typical computing purposes. This is where most users perceive performance, how fast windows open when clicked and application load times.

Random Write Performance


The 1TB Delta RGB does deliver strong random write performance thanks to the SLC buffer. The drive scales as we increase the workload through queue depths.

70% Read Sequential Performance


Another area where Micron's 32L memory disappointed us was with mixed workloads. The Delta RGB shows the same issue with the 1TB drive hitting a brick wall at 400 MB/s using a 70% read pattern.

70% Read Random Performance


The picture looks much worse with random mixed workloads. The drive starts with nearly 15,000 IOPS at QD2 and barely surpasses 20,000 IOPS when other drives deliver three times as many IOPS.
