so what do you guys think about the newest pro the 850? To me this thing is just like the evo series? Am I wrong?
 
?

It's MLC

Its basically a better 840 EVO with excellent reliability (no TLC)

The NAND structure is totally different than the previous models. The durability gains are massive. It's not just like the 840 Evo.
 
Its probably the best ssd in the market atm, but to me the price makes it not worth it, given that there is the 840evo or crucial mx100 giving lots of performance for a fraction of the price, among others.

We are starting the transition toward m.2 and sata express, personally i think its a waste investing on 850pro, i would suggest to take an EVO and wait for new ssds and the new standards to settle in before committing a good amount on an SSD,

Samsung will be releasing new ssds soon, like the Samsung SM951 in m.2 and 2.5 (im guessing it will be sata express), Samsung: With 3D V-NAND and NVME into the terabyte era
 
It's MLC, yes, but because it's stacked, they get to go back to 40nm instead the 19nm that the EVO used. Each die shrink reduces performance and endurance, so being able to go back to 40nm for a 1TB SSD is huge.

The 850 Pro has a ten year warranty on all four sizes from 128GB to 1TB. Samsung claims to have a 128GB 850 Pro test unit with 8 petabytes of writes that's still going.
 
Great on paper. In practice, the same as any other SSD. Too expensive right now.
 
too expensive 700.00+ for the 1 TB version where you can buy a entire PC for that price.;
 
Sata3 is maxed out. I wouldn't buy one, M.2 /sata express or bust.

It's an enterprise drive at a new lower price point. I see this drive being the performance and reliability leader for a very long time. The wild card is the new non flash based technologies however I have not seen much lately from the promises they made years back.

I still would like to see an SSD out SATA1 at 4K low queue depth reads.

On the topic that drescherjm mentions - no SSD on the planet is maxing out the SATA3 interface in consumer workloads except for file copies.

Low queue depth (1 - 4) which is the typical QD for OS, games and applications, are probably not even reaching SATA1 bandwidth levels, and if they are, it's just barely.
I would love to see manufacturers focus even more on this metric. Anandtechs Bench lists the absolute king of low QD 4K random reads (the DC P3700) at 130 MB/s. 2nd and 3rd are 850 Pros at ~100 MB/s each.

So, still quite a way to go before reaching that SATA3 limit for consumer workloads.

Like the drive but disappointed that there's no M.2 or Sata Express.

The 951 should be m.2 and probably sata express, from Samsung: With 3D V-NAND and NVME into the terabyte era

That's still an incredible amount of processing for normal usage though.

That's 1024 kilobytes * 100 for 102,400 bytes in 100MB. Divide that by 4 and you get 25,600 4KB files read in 1 sec.

Should make Windows Tuesdays more acceptable.....
 
Yea, I'm not saying it's slow, I'm just saying there's quite a bit to go before the SATA3 interface is the biggest bottleneck in consumer workloads. :)
 
8 petabytes wow, that is getting into SLC territory right?
8 pb / 128gb = 65k writes per cell !

IIRC SLC was rated at around 100k
 
If I had to invest top dollar for a state of the art SSD today, I would seriously consider going all the way and get an Intel SSD DC P3600 800GB PCI-E. :cool:

About twice as expensive as the Samsung 850 Pro 1TB, yes, but you get superb performance and enterprise quality to boot in a package there you wont be thinking about whether you should have waited for a modern NVMe solution.

Go BIG or go home. :p
 
Guyz,

If I buy any (x4) Pcie SSD OR SM951... can I run it on my mobo without slowing my GPU lanes to x8 instead of the default x16 ?

Am using Asus Z97 Deluxe and it has all those lane sharing which due to my limited knowledge getting me extremely confused....

EDIT: Single GPU setup always

Do GPU cards even need 16 lanes of PCI 3.0 yet? Or do you have more than 1 GPU? Although unless you have an unusual setup you probably will not benefit that much from a PCIe SSD. In most desktop loads or gaming you will not have a high enough queue depth or do large enough sequential transfers to have the internal raid0 of raid0 make a noticeable difference in anything other than benchmarks.

Consumer workloads may be low QD, but not 100% 4K low QD, very far from it.
 
I don't believe I stated anywhere that it was, but I guess I could've been more clear. Thanks for clarifying!

Yes I know GPU don't require x16 lanes of PCI 3.0... but I still would like to know, in my given example if I could run @ 16x !

Also, I am really wondering Going frm any current SSD to 1GB/s Sata Express OR maybe 2GB/s Pcie ssd -- Will it translate into loading windows in an instant and opening MS word, Photoshop in a sec. ?

I am not a benchmark junkie and only believe in performance that a consumer can see in real.

I would say neither of these will benefit much from a PCIe drive. Lower latency is what each of these need not more bandwidth.
