Slow SSD ? · DIGIT-ARC

I have added samsung EVO 840 250 G SSD to my laptop (RV518 samsung).
I see following in hdtune :

I guess, I should get 400mb+ .. tried Samsung's Magician, it shows little higher stats but not much difference..

How much free space you have left in drive and how old is that drive?

Its one day old and have 192 GB free space as of now.

Have u plugged it in a SATA 3Gbps or SATA 6 Gbps port ?

Well, it has Intel HM55 chipset, as per it has probably sata II 3GBps port but still 3GBPS > 500mbps

I don't think that Sata II can't give atleast 500MBps

3gbps =375MBps at MAX. You don't get max because of reasons such as voltage leakage etc.
The speeds are okay.

I think that 375MBps is read+write. So, average of 165MBps is justified.

I have the same ssd and faced the same problem even when I had connected to sata III 6Gbps port and cable.
Samsung 840 evos and the normal 840 ones have a bug due to which their read speeds becomes slow.
Please update to latest firmware and install the performance restoration software which they released to remove the bug.

Anandtech guys were very vocal for this issue and Samsung acknowledged them and brought this fix asap.

Please read the links I posted earlier..
Having the latest firmware won't remove the bug, you need to install and run the performance restoration software too.

This. Use the Performance restoration tool to get the latest firmware EXT0CB6Q though the website doesn't list it.

On the same page where you took that screenshot, go further down and you will find the software.

That did the trick.

Although no change in benchmarks, I guess I will get better results if I use it on some more latest sata 3 supported laptop. I have another more recent laptop, will try on it soon.

Yes it worked for me. Try with SATA III, you should see the improvement.
