Samsung SSD 840 (250GB) Reviewby Kristian Vättö on October 8, 2012 12:14 PM EST
Performance vs. Transfer Size
ATTO is a useful tool for quickly measuring the impact of transfer size on performance. Similarly to the 840 Pro, the 840 is a high performer at small transfer sizes, which is an area I think too many SSD vendors are ignoring. Not all IOs are huge in size and while the small IO read/write speeds aren't big enough to be used for marketing, they play a role in real world performance. In write speed the 840 tops out at 250MB/s, which is low compared to many other SSDs but otherwise the 840 performs very well.
