Great performance at this form factor and price point
TLC write speed of the 500GB capacity could / should be faster
Prices are still running higher than competing budget products
I've chosen to split the caching results off of the respective product pages in this review so that we can better compare them side-by-side on this page. First lets look at 750 EVO vs. 850 EVO at each capacity point:
Thanks to the plethora of data we have at our disposal from the new suite, I can derive some additional interesting data that nobody seems to have been paying any attention to yet. Have you ever deleted a large file and then noticed your system seem to...
These are the Mixed Burst results introduced in the Samsung 850 EVO 4TB Review. Some tweaks have been made, namely, QD reduced to a more realistic value of 2. Read bursts have been increased to 400MB each. 'Download' speed remains unchanged.
These results attempt to simplify things by focusing on what really matters - the Queue Depths that folks actually see when using these products. A dimension is eliminated from the previous charts by applying a weighted average to those results. The...
Just as we did on the last page, I'll start us off with Sequentials:
As we get to the 500GB model, we note that the increased parallelism of flash dies and added DDR cache help keep performance more consistently near SATA saturation at varying queue depths.
The 250GB model comes in slightly higher than the 120, but still a bit shy of pure saturation of the SATA interface.
Now for random access. The blue and red...
Before we dive in, a quick note: I’ve been analyzing the effects of how full an SSD is on its performance. I’ve found that most SSDs perform greater when empty (FOB) as they do when half or nearly filled to capacity. Most people actually put...
