Samsung SSD 850 Pro (128GB, 256GB & 1TB) Review: Enter the 3D Era

Samsung has always been pushing hard with power consumption and the 850 Pro is another proof of their efforts. Slumber power is down by a bit compared to the 840 Pro and generally speaking the 850 Pro is one of the most efficient drives. Even load power consumption stays at below 2.5W, which is superb given the performance of the 850 Pro.

Fascinating stuff, thanks for the in depth analysis.Iketh - Tuesday, July 1, 2014 - link
Good read on the software not taking advantage of SSDs yet. Windows is the biggest offender. I have 8 threads and an SSD and I still have to wait for each of my startup programs to load like a snail 1 at a time after bootup...tetsuo77 - Monday, June 30, 2014 - link
"There are some drops, although I am not sure what is causing them"It looks suspiciously like your values overflowed an unsigned int (prior to being converted from B to KB). Just add ~4.3 million to the 4 mysteriously low values and you have a nicely shaped curve.

Oops.. I pasted the wrong quote. Meant to quote this: "It looks like read performance scales quite linearly until hitting the IO size of 256KB where RAPID stops caching"I maintain that there is an error in the numbers on the graph :)

32 bit unsigned integers support around 4.3 billion, not million.lyeoh - Friday, July 4, 2014 - link
if the values were being stored internally as bytes and not kilobytes it might overflow as tetsuo77 mentioned. 4.3 million * kilobytes per sec = billions of bytes/sec which could overflow.nirwander - Monday, June 30, 2014 - link
I cant see how they aim at mainstream with these prices.Crucial MX100 512 is already fast enough for SATA 6 Gbps and.. twice as cheap!
Technology geeks will probaly go for Intel PCIe NVMe drives.

And if you really need the performance, just get two of the MX100s and RAID 0 them.willis936 - Tuesday, July 1, 2014 - link
Unless you care about storage latency at all.Gigaplex - Tuesday, July 1, 2014 - link
Fair point, but SSDs are so far ahead of hard drives in terms of latency that it hardly matters.
