Slow SSD Speeds randomly

[IRT]

Hello all, just trying to see if anyone has thoughts on my SSD issue.

 

I have a Crucial MX500 2TB Sata-SSD as my storage drive and it's running super slow...

using AS-SSD speed test shows read speeds around 403 MB/s

 

however write speeds are around 2.80 MB/s (yes less then 3 MB/second) ... (actually varies but it more avg around 5MB/sec when it's having the problem)

any idea what's going on? the drive is only about 1 month old no smart errors or anything else.The odd thing is it kinda happens at random, sometimes it's working at full speed around 450MB/s write then randomly it runs super slow again.... very frustrating.

 

I've tried trimming the drive and not sure what else to do.

I have also tried a new SATA and Power cable into the drive however this hasn't helped.

There are no SMART errors or anything else appearing and firmware is up-to-date. AHCI LPM is set to ACTIVE in power management.

 

 

I've added a video which shows the issue https://youtu.be/QooLMMjUOeU

I know it's boring but it does clearly show what the issue is.. around the 2min mark SSD speeds return to normal.... this drive is for storage and not the C Drive. It has approx 45% free space remaining and temperatures are fine under load

I'm running old P8-Z68-V Pro with i7-2600K
The MX500 is filled over 50% and used as storage, connected to SATA III from intel chipset.
And I have the "new" version of MX500 on sm2259 and 96l TLC micron NAND
Older firmware M3CR032 then yours. 
Something is really wrong with your benchmark score. 

Try to run Crystaldiskinfo, and post here screenshot of all the SMART parameters. (change the RAW parameters, from HEX to DEC before posting screenshot)

I'm pretty sure there is nothing wrong with the hard drive. You can't go by the file explorer progress bar as it will shift ALOT depending on the amount of files, file types and sizes. Use CrystalDiskMark (https://crystalmark.info/en/software/crystaldiskmark/) to bench mark the drive every now and then to see if the bench marks continue to score similar scores. 

 

PassMark Software has a performance test I really like to use (https://www.passmark.com/products/performancetest/index.php) and they also have a BurnInTest that stress tests your computer (https://www.passmark.com/products/burnintest/index.php). I would give the BurnInTest a run and if it passes it passes.

 

But yes, do not use the file copy speed bar that explorer.exe shows you when you copy/move files. Your speed is going to range and you can even be CUP bound (e.g., trying to cache file list or some shit). This is NORMAL on all hard drives (NVMe, SSD - SATA, mechanical).

Also, I would use Task manager to check and see if perhap a process in the background is killing your copy speed such as McAfee.F***ing work computers have McAfee and it can chock the computer harder than homer Simpson choking Bart. If you have like 50 different processes using the disk at the sometime you are trying to copy a file it is going to slow the file copy speed (even though the hard drive is working at full read/write speed).

Here is an example of what I mean how background processes can run in the back. You see my system is also pulling 162.3 MB/s while CrystalDisk (pulling 1571.8MB/s) benchmarks my drive. The system process is taking ~10%.

it is just randomly going from 5.4 approx MB/s to 40 then back upto 400-500 write speeds

 

it's a pain because when it runs slow it legit takes 3 seconds to open a folder in the drive in file explorer. legit 3 seconds to open the folder and list the contents

Yes this is why in my video I also did a compression test via AS-SSD - it also shows the same result with the slow write speed

Here is another speed test I just did for it to only score 4.XX MB/sec in the write tests means the drive sat there to do the whole 1GB test at those speeds... anyone have ideas?? at this rate I really worry there's something wrong with the drive surley it can't be this slow even if the cache was full ??

Interesting, I got a feeling perhaps you have a background process eating up your resources. 

 

Open task manager and have it to show programs at the top which use the most disk resources (See image for a Windows 11 example). Then run a speed test and see what other process are running in the background. Like in my example the normal background processes are System.exe and Snipping Tool.exe while bdservicehost.exe, anti-ransom.exe belong to my antivirus. When you run the bench mark took it should be the process using most disk speed. But I'm interested in knowing what other processes you have running in the background that could slow down your benchmarking test.

Thanks but no point in doing this test as the SSD shows similar results in a totally differennt PC saldy ........ my next step now is to totally format the drive and continue testing before starting RMA

I have these logs in hdd sentinel for the ssd , anyone know what they mean?

do that

it's the C5 SMART parameter, that indicates bad sectors on the drive.
That's why I asked about the Crystaldiskinfo screenshot with all the SMART parameters
