Sandsisk SSD Plus 120Gb - much slower then it should be. Any ideas? (Not very high priority).

[EvilHamster]

Hi all. I know this kinds of threads have been made a hundred times over. I am sorry, but I was not able to find a solution.

Basically my SDD is underperforming, see pictures: https://s27.postimg.org/lxw3fkdsz/Crystaldiskmark.jpg, https://s24.postimg.org/luryh4lbp/Hdtune.jpg.
(P.s. webpage was not loading in the second picture.)

My mainboard is H77 Pro4-m (Asrock).
I have done the basic checks.
I have plugged it with a 6Gb/s cable, in a Sata 3 connector. I also have AHCI everywhere enabled in the `Bios' (well UEFI).

It is a fresh Windows 7 install, I only installed the drivers that came with the board (but not the utilities ofc.). Well Lan driver obviously, and then things like Intel Rapid Drive thingy etc. (not 100% sure of the names, I can check if needed, but I don;t thinkk they will not hurt the performance, at least not that much.)

I mean the SSD speeds are... fine... they are not unbearable, they are still much faster then my HDD, but it is very much under performing. I expect that, when an average Brand SSD claims to be 530mb/s, that it is only going to be 450 or so in everyday use, but not 350...

Any ideas?

That board probably has SATA II ports. Check it's in a SATA III one.

EDIT "- 4 x SATA2 3.0 Gb/s connectors, support RAID (RAID 0, RAID 1, RAID 5, RAID 10, Intel® Rapid Storage and Intel® Smart Response Technology), NCQ, AHCI and Hot Plug functions
- 4 x SATA3 6.0 Gb/s connectors"

As I said , I checked that it is in a sata 3 port (a few times)

And 120 GB ssd's have less cache that say the 250 GB ssd's. That maybe another reason

Nah it's underperforming I think. I know what you are saying, but according to this it should do better (Pretty lousy write rate tho!) https://www.scan.co.uk/products/120gb-sandisk-ssd-plus-25-ssd-sata-iii-6gb-s-read-520mb-s-write-180mb-s

Seems to be capped at 350mb/s SATA II speeds somehow.

Is there a setting in your BIOS to change the SATA mode of each port?

Is there a setting in your BIOS to change the SATA mode of each port?

Could you elaborate on that pls? (P.s I am answering on my phone, since I have turned off my PC, as its quite late here. I will have to check it tomorrow.)

 

[Multipack]

Ok well had a look at the manual, and first you need to check it's in a grey port not a black one, but you said you made sure it was a SATA III port. You could get SandDisk's software to double check and to give you some more info tho http://kb.sandisk.com/app/answers/detail/a_id/15108/

In your BIOS, under Advanced Storage Configurations, what settings do you have? Can you post a screenshot? I think two of the SATA III ports may run properly as two have an ASMedia SATA controller.

Thanks Multipack for the help thus far.

I went into the Bios and took this picture https://s28.postimg.org/gmla27ip9/IMG_20170111_092613_1.jpg (again, a bit zoomed in https://s24.postimg.org/8oei4xv3p/IMG_20170111_092602_1.jpg).

I also checked again that I used the right port. I used port 12 (A_1). It is the grey port, farthest away from the corner. It is a SATA III port and the cable is a Sata ATA 6G cable, which is, I believe, also SATA III.

 

[Multipack]

Yeah it all looks like it should do as far as I can see. Could you maybe try the non-ASMedia SATA III port (_1 not _A1)? I don't see why it'd make a difference, but I cant really see any reason why it isn't working myself.

You could also try disabling power management because that probably doesn't help, and turn SMART mode on.

Is it a new SSD?

 

[EvilHamster]

Amazing. It worked. I did the things you said, changed the port form A_1 to B_0, turned off power management and turned on SMART. Now its super fast. https://postimg.org/image/vqkpyddw7/

I have no idea why it worked, but hey it worked. Thanks a bunch mate.

P.S how can I select your answer as the right one? There is no `pick as the solution'.

 

[Multipack]

Cool. Power management will mess with latency as its is supposed to save power and SMART needs to be enabled on SSD's usually, plus you have two different SATA controllers so I guess one of them isn't as good. Am glad it worked anyway. Nice speeds too!

No pick as solution because it's a discussion style thread. Am just glad you found one.

 

[EvilHamster]

Well sorry I can not pick it as a solution. But I would if I could .

Cheers.

 

[Multipack]

Ha no worries bud. Am not worried about that.
