SSD in sata 3 but only achieving 170MB/s

[Crafting]

Hello

 

I have a Samsung 850 evo SSD plugged in a sata 3 6Gb, but it only achieves 170MB/

 

How can I make it utilize the full bandwidth of sata 3?

 

Useful specs

This MOBO only has 2 SATA3 ports.....

1. Are you sure you have the SSD plugged into a SATA3 port?
2. Are you sure the SATA3 drivers are installed?

Go to BIOS ad see which port the SSD appears under. If it's SATA2 or SATA3GB then you have plugged it in to the wrong port.

Yes it only has 2 sata 3 ports

 

1. Yes, it's plugged into one of the 2 white sata ports, there is 6 black ones (indicating sata 2)

2. Shouldn't it be supported natively? I've tinkered a bit trying to figure out if there were any new drivers or such, but nothing helps

It says it's plugged in to sata 3

It says it's plugged in to sata 3

Does it only say SATA 3 or SATA3GB? That's a difference.

[Starelementpoke]

There can only be one explanation, you got a re-branded V300.

Im pretty sure it said Samsung 850 Evo 250GB                       sata 3

 

so I worry

I doubt it, it is recognised in the Samsung Magician program, and supports various utilities such as rapid mode, which is unique to Samsung SSD's

I mean, the motherboard. It has 2x SATA3 ports, make sure you plugged it in correctly.

Check physical connection to motherboard (consult your manual to figure that one out) Then check the mode in the BIOS, should be set to AHCI mode

Is AHCI enabled?

It's plugged in correctly, don't know how it couldn't be, the locks are activated on the connection.

It's plugged in correcly, the Samsung magician software says it's on AHCI mode. And with the confusing BIOS menu, I think it's set to AHCI

The Samsung Magician software says so.

Guy......

 

the 2 white ports, ports 7 & 8, are SATA6GB/s ports from the Asmedia chip.....you MUST install the driver for the chipset for it to work properly/at the advertised speeds.

 

read the manual.

Dont always trust magician to give you the details of your drive, I had a lot of issues with it when W10 first launched, it cut my SSD benchmarks in half because it couldn't correctly detect AHCI mode.

You need some other software, try Crystal disk mark, if you get the same errors it would be time to look at the BIOS for next logical step

Makes sense, but the drivers are installed, and it's still at 200/170MB/s limit

 

Still my hotswap bay for my 2nd SSD that i'll put in my laptop afterwards, doesn't even work in the sata 2 ports

My next step would be to check device manager to see if you have any reported issues concerning drivers, then i would update the BIOS.

 

Then install and use Samsung Magician v4.9 which is the latest then check again.

I had the chipset drivers, but now I've found some newer ones with the MSI updater program, the bios and drivers has been updated, but still, nothing has changed

 

This is becoming tidious, im guessing it has something to do with the Asmedia 105x 1061 6Gbit driver, or something like that

It could very well be. I highly doubt it is the SSD because most of the 850EVOs have had a good track record but i have seen a few with bad speeds and Samsung has stated to contact their support for any help, i think this should be your next step on the chance that it is the SSD just being a bad one.

Alright, I'll try a different ssd, I have 2 of them, and I'll report back, but my HDD doesn't work in the sata 2 ports either, which makes me curious

Then this could be......

1. the proper drivers are not installed
2. the ports are dead
3. the cable is broken
4. the SATA configuration is not in ACHI mode

I would try clearing the CMOS via this method....

1. shut down the PC
2. unplug the PSU form either end
3. remove the RAM
4. remove the MOBO battery, wait about one minute then put it back in
5. plug in the PSU reboot
6. you will/should be asked to go into the BIOS to make changes
7. ensure the SATA is in ACHI mode
8. check if the problem is fixed

Alright, I changed the SATA setup

 

HDD Sata3

Future OS SSD Sata2

Hot-Swap bay with SSD Sata3

 

When the external SSD is plugged in, the whole system slows down, programs stops responding, and when I unplug it again, things load again.

Also the HDD is under some conditions under 100% usage even though it's not reading nor writing.

 

The SSD achieves speeds on 275/255MB/s which is....better than before, but of course all but ideal.

 

I'm trying to migrate the OS from the HDD to the SSD, and then hopefully later, put my Laptop HDD content in to the second SSD

 

Still weird that the HDD doesn't work in Sata2 ports...

Is the SATA 3, SATA3 6GB/s or SATA3 3GB/s because if it is the later then i would understand the SSD speeds but i still don't understand the HDD not being read but still at 100% usage...that makes no sense. 

 

Have you checked Windows Computer Management to see what is the health of the partitions and the drive letters? To open Computer Management you need to right click Computer and select Manage and this is what you need to check....

1. that all drives are NTFS file system
2. all are healthy and active 
3. only one drive should be boot
4. the boot drive should be disk 0
5. there are no unallocated space on any of the drives especially the boot drive

Alright, just switched the SSD's (Internal SSD on Sata2 Exchanged with External SSD in the X-Dock plugged in Sata3)

 

Here it says 6Gb/s Asmedia Controlled

 

http://asset.msi.com/global/picture/feature/feature_20101211120550.jpg

 

As written on the Motherboard site

• 2 SATAIII (SATA7~8) ports by Asmedia® ASM1061

- Supports storage and data transfers at up to 6Gb/s

 

Other useful info

Integrated Peripherals

Extra RAID/IDE Controller: AHCI

On-Chip ATA Devices

PCI IDE BusMaster: Enabled

On-Chip SATA Controller: Enabled

RAID Mode AHCI

Boot Sequence

1st IDE: 1TB HDD

2nd IDE: Samsung SSD

 

All Drives are NTFS

Drives are "Healthy"

Only one boot drive (HDD)

Boot drive is disk 0

There is no un-allocated space on either of the drives

 

Concluded something tho, without a solution, the hotswap-bay is not functional with the current settings at least, it's causing the whole computer to not respond much, whenever I plug an SSD or HDD in, might be a sata3 problem? I'll try switching back to Sata2

The Asmedia ports are the white ones.

 

The boot sequence should be SATA and not IDE as i am sure the SSD is not IDE.

 

Normally you have to set the port to hot-swap in the BIOS but this is only if the port is compatible with hot-swap.
