Am I Reading This Right?

[byalexandr]

How is this happening? I just got a (not very old) 512GB Samsung 840 PRO SSD. I moved my OS from my SanDisk U110 to this and updated firmware, enabled everything, etc.

 

Also, when I tried to move over my Steam library to my SSD from my HDD, it was EXTREMELY slow. Like the drives (both the SSD AND HDD) didn't even show any active time while it was transfering. Any help on that?

 

EDIT: In case you can't see, it says I have 2000+ read when the drive is only capable of up to 540. This happens OVER and OVER everytime I run the benchmark.

try another benchmark like crystaldisk

When transfering from the HDD to the SSD, you will be limited by the read speed of the HDD...that's a given.

 

The reported god-like sequential R/W speeds... IDK... freakin' weird.

Its samsung rapid mode being enabled: http://www.samsung.com/global/business/semiconductor/minisite/SSD/downloads/document/Samsung_SSD_Rapid_Mode_Whitepaper_EN.pdf  its buffering the files in the ram which is why the write is super fast, its putting the data onto the ram

[Rheinwasser]

its the caching software that samsung uses. its a known 'problem'.

@gollum99 was faster than me.

I just ran this test as well on the 240gb versoin of that drive.

Yeah, but the HDD has way faster transfer speeds than what I was seeing. Both of the drives showed no active time in task manager and only a few files were moving per second. Like extremely slow transfer speed, as if something is wrong. As for the AWESOME speeds, I will try crystaldisk as @ind3x mentioned.

Makes sense, when I enabled that the speeds shot up.

How are you getting such high Randoms? Mine didn't even reach the max.

Is your firmware up to date?

Is your firmware up to date?

Yes, I was having problems before I updated the firmware. I was worried so I did chkdsk /r on my HDD to make sure it was okay; only found a couple bad sectors. During that the SSD would freeze up and show 100% active time and basically crash my system. After a TRIM operation and firmware update among other things it is working MUCH faster now. Faster than my trusty old SanDisk SSD. I still can't figure out why the transfer speed is so slow.

Reason for the slow speed could be that it were many, small files. 1 1gb file copies way faster than 1000 1mb files!

Here is with crystal disk. I see that the RAPID stuff helps A LOT.

Still, it was copying many, small files and each of those small files were going extremely slow. Is there any way to fix this? It said the ETA was like 92 days or something, and I cna't wait that long to play my summer sale buys.

1328 sequential write... wtf.  I wish I knew how to help you, but I do not.  I will be reading because I am interested in knowing as well.

Coyping small files sucks, maybe try zipping them into on archive and move that over

1000mb =/= 1GB in Windows. Windows uses binary for storage, not decimal. Point still applies though

Maybe I didnt want them to be the same size? yeah 1024mb blabla nobody cares

Hey byalexandr,

 

Those speeds are high most probably because you have enabled RAPID and the system is bench-marking your RAM instead of the drives (SATA3 (6Gb/s) has a limit of 750MB/s and there is no possible way of achieving these speeds with just one drive with a SATA port). For a more accurate estimation, I would run the benchmark with the RAPID option turned off.

 

Regarding the transfer speeds, they depend on many things including the size and number of them. Many small files will always transfer slower compared to one or a few larger ones. The fact that you are transferring files from your HDD automatically limits everything to the read speed of your hard drive. I would run a benchmark and see how fast exactly is it running.
