Running Samsung EVO 850 on Old PC - Getting miserable Write Times!

[hazel1919]

I am using the P5K motherboard with SATA II ports on IDE mode. I just installed a brand new Samsung EVO 250GB SSD today and my boot times have not been incredible... I did the benchmark and for some reason my random write speed is abysmal... how badly could this be affecting performance?

From my understanding some ssds do not like ide/legacy configs only ahci controllers.

Thanks guys, so I suppose this brings up a whole new set of troubles!

Something is wrong. It must be near 550. This is my score on my Evo 850 :

Something is not happy on my system, still my boot times are cut in half...

Maybe try change sata port or format ?

[hazel1919]

hmm, I have tried al the SATA ports on my MOBO... the problem is that I am not in AHCI mode .... and short of messing with a modified bios I doubt I will...

Do you have Rapid mode enabled? I took the benchmark test twice and both were waaay off..

I check in samsung magician and i am in AHCI mode ON. You have system on MBR partition or GPT? I have on GPT Windows 10.

And Rapid mode?

It would be great to do some research before thinking you might have a problem?

1. The SSD you have runs at SATA 6Gb/s or SATA III

2. The motherboard you have the SATA ports only goes up to SATA 3Gb/s or SATA II

3. Your SSD will not run at its maximum performance when it's plugged into a SATA II port

4. The write speed of a SSD will still be faster than a HDD. Most HDD write tops out around 70Mb/s with WD Black going around 100Mb/s. Some new ones around 150Mb/s.  For the SSD to have a write of 371Mb/s it's still really good.

5. Update your chipset and controller drivers, it may improve on it a bit, but not by much when the controller itself is the limitation

6. Want to speed it up, then buy a PCIe SATA 6Gb/s card

7. ACHI is recommended for SSD to set it to that, will need to reinstall OS

8. MBR and GPT does not affect SSD performance.
