Samsung SSD 850 Pro - 3D NAND Arrives

8 thumbs up

Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a separate drive used for the OS and benchmark installations. Out testbed's motherboard was updated with the latest BIOS available as of press time and AHCI (or RAID) mode was enabled. The SSDs were secure erased prior to testing, and left blank without partitions for some tests, while others required them to be partitioned and formatted, as is the case with our ATTO, PCMark 7, and CrystalDiskMark benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test.

IOMeter
I/O Subsystem Measurement Tool

As we've noted in previous SSD articles, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real-world performance for the average end user. That said, we do think IOMeter is a reliable gauge for relative available throughput within a given storage solution. In addition there are certain higher-end workloads you can place on a drive with IOMeter, that you can't with most other storage benchmark tools available currently.

In the following tables, we're showing two sets of access patterns; our custom Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and a 4K access pattern with a 4K transfer size, comprised of 67% reads (34% writes) and 100% random access.


 

 

Both of the Samsung SSD 850 PRO drives led the pack, across the board in our IOMeter tests. We would typically expect performance to scale upward as the number of outstanding IOs increases, but the performance of these new Samsung drives remains consistent throughout. You'll see why on the CrystalDiskMark page...

In terms of total bandwidth, the new Samsung SSD 850 PRO drives once again led the pack, as you'd expect looking at the data in the graphs above.

Thanks for the informative review on two great drives. Those SSD's are fast and they come with a bonus 10 year warranty! I'm very surprised there isn't a big speed difference between the 128GB and the larger 1TB drive. Usually the larger SSD drives are a lot speedier than the smaller versions. Hopefully Samsung won't do the cheaper component bait-and-switch like Kingston and PNY have done with their SSD's.

holy molly its so expensive, but i guess it would be worth it if i was an enthusiast with all the money in the world.

really good deals on amazon though its like 47% off right now the 512 version

Yeh, this technology is still too expensive. Will not buy 1TB until it's down to at least $250 (which can be forever), or until another cheaper better performing technology comes out. I have a 128GB SSD just for my OS, even that was too expensive...

At the current rate, 1TB for $250 will happen sometime in 2016, maybe a bit earlier if competition heats up and 3d tech proves cheaper and more reliable to make. Just think of it, two years ago low end SSDs were about $0.80-1.00/GB, now they are down to $0.40 (when going for 240GB+ drives) and even high end drives are below a dollar.

These are still super expensive. But crazy to see 1 TB SSD didn't think they made them that big yet.

I have 2 of 840pros and they work great, the warranty is double so that's really impressive. I don't know if the that much more better, maybe a bit more stable when running benchmark tests...

Very nice drives. I love my 2 840 pro's. Very speedy drive's.

Ok, I am salivating... Cannot wait to get an SSD drive!

Great review. These seem like a great choice if you are looking for an SSD.
