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.

"cheese in in" -> "cheese in it"?Cerb - Tuesday, July 1, 2014 - link
The above was meant to not be a reply to yours. In general, there's isn't much, though, because with SATA, we're still stuck needing striped RAID to improve bandwidth. Assuming they can keep costs in check, the rapid shrinking,m and thus capacity increases over the next few years, will give us something much more useful. That said, it's nice that they caught up in terms of consistency.Donuts123 - Sunday, July 6, 2014 - link
More relevantly, the 150TB warranty figure applies to all capacities. All things being equal, a 128GB drive with 150TB written will have the same amount of flash wear as a 1TB drive with 1200TB written.So in practice the 1TB model will have far higher endurance than 150TB. But its warranty will expire when its flash is only 12.5% worn. Samsung aren't the only manufacturer to have low TBW warranty figures; Micron/Crucial does it as well, with the same TBW figure for all drive capacities.

Yawn. Another SATA 2.5" SSD.How does this compare to m.2 PCIe drives like the XP941 and M6e?
Will we see m.2 PCIe NVMe drives before xmas?

The 850 Pro is now in the Bench so you can compare the two easily:http://www.anandtech.com/bench/product/1201?vs=125...

thanks, the XP941 demolishes this thing, why isn't it in the charts of this review? clearly PCIe m.2 would be on the radar for anyone looking for a high end SSD these days... ?it may not be readily available in the channels, but it is a taste of what is to come... personally I just got a 256GB plextor M6e PCIe m.2 for $220. It's easy to find in the market.

I didn't want to put the XP941 in the graphs because the availability and support are relatively limited and it would have broken some of the graphs.zmeul - Tuesday, July 1, 2014 - link
just a quick dumb question:the bandwidth for SATA 3.0 - 6 Gbit/s is 600 MB/s right? so, it's 300MB/s read and 300MB/s write
correct ?
thesavvymage - Tuesday, July 1, 2014 - link
no, its 600MB/s in total in either direction. you can max the 600 read if you arent doing any writes, etc. It isnt 300 max per direction, its 600 max for total data bandwidthzmeul - Tuesday, July 1, 2014 - link
yes, I forgot to mention, duplex (at the same time) 300r+300w
