Samsung 960 PRO / EVO Owners Club - Page 162

post #1611 of 1752
Might sell off my Samsung 960 EVO 500gb as well. It's not as snappy as my raid 0 ssd setup and the boot time is a bit longer since i'm on old architechure that doesn't support it offically. As well as not being able to 'fast boot' this thing. Might as well downgrade to windows 8.1 as well as I don't like forced hidden update on windows 10 spyware reinstalling onedrive and other crap I've disabled. Using third party anti-spayware stuff really crippples the OS for some dumb reason as well as they really don't want that stuff to turn off. You can't even turn off onedrive on your PC no more.

Running benches in compressed uncompressed modes. I see no evidence that the 960 pro does any compression of data. I doubt that is the difference.

Believe what you want, it's fact.

Bencmarks like atto/CDM use RAW/compressible data.

AS SSD does not, which is exactly why sandforce drives do not do as well as they cannot compress the data when writing to NAND

This means you cannot directly compare the benchmark results as they use different ways of testing performance.

Yes, these benchmarks use data whose compressability is different. That is a fact.

This isn't a drive with a sandforce controller, it does not do compression so how compressable the data is doesn't affect it. Believe what you want.

You can with an option use compressible data in AS SSD. Try it on a 960 Pro. You will see no difference between it and the default incompressible data like I did. Here is a review that did the same:

Guys i heard Samsung 960 has high failure rate, is it true? Do they really broke so often? I want to buy 960 evo or pro.

I haven't had my pro long. Only 124 hours logged on it. But it has a 5 yr warranty.

Everything went smooth during the installation, and Samsung Magician recognized that my 960 Pro was connected using PCIe 3.0 4x like it's supposed to. I also have the latest Samsung NVMe drivers, 2.2 installed. Regular day to day performance as far as boot up time and loading applications is faster than it's ever been thanks to the new SSD, and my synthetic benchmarks are all in order and appear normal.




Anyway, I've noticed that I'm getting a lot of stuttering in certain games, much more than I was previously. For instance, Witcher 3 is no longer a smooth game, and the storage access light on my case lights up like a fricking Christmas tree when Geralt is moving, especially in highly populated areas like Novigrad. Batman Arkham Knight is the same thing, though not as bad as the Witcher 3.

I know it has something to do with the drive, as I still have my old 850 Pro with a full Windows 10 install plus all the games. So I reinstalled the 850 pro, keeping the same UEFI settings and confirmed that everything was back to normal ie no stuttering.

My question is, have any other NVMe owners noticed this? Or have I made some mistake with the setup as this is my first NVMe drive?

Another possibility that I've thought of is that it's possible that since NVMe is a relatively new I/O protocol, the vast majority of games' asset loading is probably still optimized for slower protocols like SATA.

Any help or advice would be much appreciated thanks!

The issue has been solved. The source of the problem was Windows itself, specifically the Creators spring update! After clean installing Windows 10 Fall update, the issue has been completely fixed, and Witcher 3 plays buttery smooth on my 960 Pro the way it should have from the get go! smile.gif

Microsoft admitted that in certain games and applications, the Creators Spring update could cause stuttering and lag, though they never specified what caused this to occur.

Well whatever it was, it has been completely and totally fixed with the Creators Fall update. So if your games are stuttering and you can't figure out what the cause is, try updating or clean installing to the latest Windows 10 Creators fall update!

The reason 960 pro performs the same in incompressible vs compressible data in ASSSD is because it's good at both.
That option only changes the file types, nothing else.

Sandforce would score higher obviously in those compressible tests.
That still has no bearing on the way other benchmarks work regarding test length and file size length.
Which you are not understanding.
post #1619 of 1752
That is absurd. The reason it performs the same is it doesn't do compression. Try it with crystaldiskmark. By default it does incompressible files. But you can choose to do all zeroes, or all ones, both of which are completely compressible. The performance is the same.

The 960 pro controller does not compress data.

installed a 960 evo in a dell AIO (which came from the factory with a M.2 SATA option but there were configs with NVMe)

anyways, can't get it to boot in UEFI, BIOS is updated, Windows Disk Mgmt shows it's GPT but under DISKPART there's no star under the GPT column

benchmark shows it running at full speed, any major drawbacks for leaving it in legacy boot? don't care about boot times but it sucks that I can't get it with secure boot which would help in a case of a nasty virus..

the household now has three 960 pro, two 960 evo, a 850 pro and three 850 evo

gonna stick the sandisk z400s into the xbox one X when I get it...I no longer want to boot from a hard drive again tongue.gif
