SAMSUNG 850 PRO BENCHMARK TESTING
The exterior case of the 850 pro is of a metal shell with bottom plate and three screws, two of which are under the branding sticker. These are also a pentalobe type screw and can be very difficult to remove. Our advise is to leave the SSD intact and not void your warranty by opening it.
Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
As shown in this ATTO result, the Samsung 850 Pro proves to be a solid SSD as is evident by the steady increase in read and writes speeds as file size increase. As well, data transfer reads and writes are as good as you are going to see for SATA 3 SSDs.
CRYSTAL DISK BENCHMARK VER. 4.03
Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples. Further, we are using the newest release of CDM where the queue depth, and even thread count, can be set.
These are very strong performance results, considering we are now starting to test with incompressible data, that similar to movies, music and photographs.
To be frank, V-NAND was not needed for 2tb ssd.
Manufactureres can easily stuff 16 packages each having 128GB space using plain ol’ 2d nand.
Yes but…the problem then becomes one of performance versus the ability to provide the necessary power to the chips don’t you think? And how about DEVSlp?
If sandisk managed to make 4TB ssd with ordinary 2d flash, i’m sure sammy could aswell.
But in just happens that there was no demand, when 19nm was still a thing with samsung.
And i dont think 3d is all that more power efficient compared to 2d to be an excuse…
What about devsleep ? Care to elaborate ?
To compare apples to apples, the SanDisk 4TB was originally shipped as a 15mm ‘z’-height form factor, as opposed to 7mm ‘z’-height for the Sammies. I do believe that SanDisk now fits 4TB into a 9mm ‘z’-height form factor. Those “taller” ‘z’-heights won’t be fitting into too many laptops or other portable devices.
The 4 TB SSD was a dual PCB design and could never fit into a notyebook case. Further, it was noit a consumer SSD. I don’t think with the powering needs of an SSD with so many chips can DEVSLP be an option; I could be wrong.
Well, with 3D there are still the same amout of chips or dies compared to 2D.
Remember, 3D NAND has the same die size as 2D — 128Gbit.
So for 2TB, they need the same number of dies, be that 3d nand or 19nm 2D.
And fitting physically so much space was never a problem of chip density. We can do 256GB per package for quite some time now (840evo msata anyone ?).
If we put aside controller and heat limitations, we could put 4TB of flash on a standard 2.5″ formfactor , if there was demand for such drive.
Actually, according to a comment by Paul Alcorn from Tweaktown, the SanDisk 4 TB SSD has 3 PCBs: https://www.networkcomputing.com/storage/ssd-prices-in-a-freefall/a/d-id/1320958
nice review les, Might these drives push the 1/2 tb models finaly closer to the $200 price point? Im still running on my Mushkin Cronos Deluxe 120 … but I think its getting long in the tooth & while I think a move to a 256 gig SSD would probly be financialy better for me … I notice the 1/2 tb’s are getting around the $300 mark. Also my other issue is im again if you remember running a AM3+ FX cpu, so im not 100% committed to replacing the board with Zen just over a year away. Sugestions?/thought?
Thanks.
I don’t really think so. As much as we enjoy seeing the lower per GB point, these drives do not compete as they are still niche and in their own space IMO.
I do not understand how ordinary consumers feel content with new computers coming off the shelf as sluggish as it were 5 years old. In actuality I HAVE put them in 5 year old machines and it’s much much faster than those new budget machines.
Not to hijack the discussion – but any M.2 SATA 850 Pro or EVO with higher capacity, or are we stuck forever at 500GB? The technology appears to me similar, yet Samsung M.2 reached 500GB some time ago and stopped.
No newer FW-version than the one which bricked a lot of users’ 850 Pros (luckily my update went well) huh?
“Samsung has set a new bar in SSD pricing”
Are you kidding? The best bar that the Samsung 2 TB SSDs set is $0.40/GB. The competition’s 960 GB/1 TB SSDs regularly hit $350-$380, the Crucial M500 960 GB was $295-$305 until recently. This is the 840 Series all over again, where reviewers gave Samsung and their 840 Series TLC SSDs all the credit for the SSD price drops that the Crucial M500 series started.
so…. where can i buy 1 of these Beast_
Why are the PCB photos of EVO rotated the other way of the PRO? It makes it difficult to compare the chips of EVO and PRO, or was that the point?
Can I partition this SSD as a logical drive? I have a 500GB 850 EVO
