New SSD slower than old drive

I recently replaced my M4 SSD 256 for a newer MX500 1GB and expected the speeds to be better, but they are actually slower. Any advice please ??

We could use some more details to provide advice please. Smiley Happy

Are you seeing it slower in benchmarks? If so, screenshots comparing them would be good.

Or is it feeling slower in use?  Was Windows cloned or reinstalled?

Is it using the same sata controller on the motherboad?  On older systems certainly, there'll be a mix of ports with some slower than others

Re: New SSD slower than old drive

Are you seeing it slower in benchmarks? If so, screenshots comparing them would be good. Sorry I do not any benchmarks form old drive as it is removed (I remember the numbers) Here are details from new drive test ..

Re: New SSD slower than old drive

Which speed do you consider slower than the old drive?  The sequential speeds certainly are as fast that older board will go and the M4 cannot have been faster.  Unfortunately you have no 'proper' Sata 3 ports on that board.  Those Marvell ports top at at about 360MB/sec - which is what you are seeing.

 

We would generally recommend you use your Intel ports (which top out at 260MB/sec) on those older boards as despite the lower sequential speeds, you'll typically get higher small file random speeds and so higher real world performance in most cases.

Re: New SSD slower than old drive

Thaks for your reply, I was expecting faster write speeds, but as you say the board is a bit old now. Maybe putting another card inside with faster more newer ports on it may help I guess.

Re: New SSD slower than old drive

Try a Windows optimise by right clicking the drive in explorer then choosing properties -> tools -> optimise

It might just be that the drive is dirty from all the writes during a windows install and setup.

 

I can't recall how good the marvell port is at writes tbh.  It's been a long time since I've seen one.  I don't think there are any good sata 3 cards at a reasonable price.  The cards tend to use marvell ports also!  Again though, it's been a long time since i last looked.

Re: New SSD slower than old drive

Hi.

Wonder if you can help with the other problem I have. I bought 2 of these drive and 1 is in the PC and the other I have put in an external case that us rated as USB 3.1 type C socket. I am continually getting stupid results when running the test and all I do is turn off the PC and nothing chnages, there is no rhyme or reason, that I can thinkof for this to happen. I have downloaded the latest drivers for the Asmedia USB PCI-E 3.1 card that I have put in my PC. So here are the readings...

As I say, all I do is turn my PC off and then the next day I get the slower speeds and then tomorrow I would get the faster speeds ??

 

Any ideas please.

Re: New SSD slower than old drive

Looks like the bottom one is running at USB2.

Re: New SSD slower than old drive

Hi.

Yes I agree and it connected to the same card with the same driver as the top reading. It is an Asmedia internal PCI-E card with an external USB C conector, which the external drive is conected to using a 3.1 Gen 2 USB C cable ??

Re: New SSD slower than old drive

How much free space do you have on these drives?  If they are fairly full, then you might see this type of behavior.  Have you tried a Secure Erase on the drives?

 

Most of my USB adapters use one of the ASMedia controllers and I haven't noticed any issues, but when I have run tests I've done so using Linux or OSX.   Maybe you should run benchmarks booting from both Windows & Linux and using the Phoronix Test Suite to compare results.   If you see similar performance/behavior with both operating systems, then hardware is most likely the cause, otherwise it is a Windows issue.
