Samsung SSD 850 Pro (128GB, 256GB & 1TB) Review: Enter the 3D Era
by Kristian Vättö on July 1, 2014 10:00 AM ESTAnandTech Storage Bench 2011
Back in 2011 (which seems like so long ago now!), we introduced our AnandTech Storage Bench, a suite of benchmarks that took traces of real OS/application usage and played them back in a repeatable manner. The MOASB, officially called AnandTech Storage Bench 2011 - Heavy Workload, mainly focuses on peak IO performance and basic garbage collection routines. There is a lot of downloading and application installing that happens during the course of this test. Our thinking was that it's during application installs, file copies, downloading and multitasking with all of this that you can really notice performance differences between drives. The full description of the Heavy test can be found here, while the Light workload details are here.
The dominance continues in our 2011 Storage Benches. The 840 Pro was already the fastest drive in both suites, so it does not come as a surprise that the 850 Pro takes the lead.

Well, kinda, I mean, some implementations come from the IOH instead of the CPU. I have heard rumors that future versions of Intel Desktop CPU's will have 20-24 PCIE lanes on them instead of 16. That would be perfect for storage!smithrd3512 - Tuesday, July 1, 2014 - link
Gotta love that warranty. 10 years on the drive. Might be worth the extra cost just for that alone.rahuldesai1987 - Tuesday, July 1, 2014 - link
"That is very aggressive because it essentially implies that the die capacity will double every year (256Gbit next year, 512Gbit in 2016 and finally 1Tbit in 2017)" - Does this mean a 8TB drive at $600 in 2017 ($75 per TB). Good bye hard drives by then :). What about a 850/850 Evo version?DarkXale - Tuesday, July 1, 2014 - link
It certainly does imply 8TB SSDs by 2017. By that point such a SSD will likely have a higher capacity than HDDs of that time.Of course, price will be very significantly in favour of the HDD still; but if money is no object you could do bulk storage in a portable device if you wanted to.

This may become an exhibit in some future dispute between Samsung and Apple. Those prices are easily Apple territory.extide - Tuesday, July 1, 2014 - link
Ehh, those prices were par for the course 18-24+ months ago!toyotabedzrock - Tuesday, July 1, 2014 - link
Does the height of these 32 layers make the cells more delicate when subjected to horizontal movement?And is this mlc or TLC?
MrSpadge - Wednesday, July 2, 2014 - link
Do, it doesn't. The height scale is still in the µm range, which is pretty much stable on macroscopic sclaes.emvonline - Tuesday, July 1, 2014 - link
thanks for the article on VNAND SSD. I think the SSD analysis is good and shows the impact. The details of Planar NAND and VNAND are incorrect in many cases. The overall NAND takeaway should be Samsung VNAND is a 86Gbit device Die level with a very large effective cell size. I still want to buy one... where can I get it?Kristian Vättö - Tuesday, July 1, 2014 - link
"The details of Planar NAND and VNAND are incorrect in many cases."Can you elaborate on that? I'm not saying that there can't be mistakes but it doesn't help me unless you explain what you think is incorrect.
