MP510 2TB NVME - slow write speeds?

Journey said:
I had this issue with two 1TB models, I wiped them after I couldn't fix the issue, which worked, and then it started doing it again. Eventually RMA'd then and got replacements as the drives were worthless to the end user with such low write performance. Still monitoring the current ones but they seem much better.

Was it just write performance and what did it go down to?

I've now run full virus/malware scans and nothing detected. Been looking at resource monitor and performance tab in task manager. The latter generally sits at 0-1% activity. Resource monitor is generally a lot higher than the 4000 bytes/sec mentioned above but just system and chrome related activity - nothing suspicious or that I could simply uninstall, etc.
 
Edit: scratch below, did a couple more checks and restarted PC. Ran benchmark again and back to under 1000MB/s... Ran it a bit later and back up to 2143MB/s. Started to wonder if it was temperature related but temps all fairly consistent.

Decided to uninstall Avast after getting annoyed with the amount of resource it was hogging and being completely unimpressed with the premium features I decided to trial.

Then ran benchmark and write speeds doubled to around 2000MB/s. I still think other stuff may be holding it back still and therefore tempted to reinstall windows but might wait a while to do that. Will have to keep an eye on total write activity to decide if I should bit the bullet...

Sequential Read (Q= 32,T= 1) : 3479.265 MB/s
Sequential Write (Q= 32,T= 1) : 1920.710 MB/s
Random Read 4KiB (Q= 8,T= 8) : 1320.028 MB/s [ 322272.5 IOPS]
Random Write 4KiB (Q= 8,T= 8) : 975.499 MB/s [ 238158.9 IOPS]
Random Read 4KiB (Q= 32,T= 1) : 571.554 MB/s [ 139539.6 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 532.524 MB/s [ 130010.7 IOPS]
Random Read 4KiB (Q= 1,T= 1) : 44.612 MB/s [ 10891.6 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 222.823 MB/s [ 54400.1 IOPS]

Yes write performance, and I swapped them into a different system to see the effect stay the same. Hence wiping and starting again, I wanted to reset the available space to the controller to see if something had gone wrong in firmware with the wear levelling, or caching on them.

Both drives going faulty at a similar time, is what made me think it wasn't the drive but something related to the system, or the host O/S etc. However after wasting too much time, I just had them RMA'd and replaced for the sake of a few days, the end user was unable to use the system as intended.
 
Seems performance has now stabilised and I've been doing some more cleanup of processes and services so will now stop benchmarking and just keep an eye on writes to my NVME. Hopefully it will now slow down dramatically...

I may also wipe and use as a storage drive when I get a new NVME.
 
If it helps I have the 490 (500GB) MP510. I use the drive for OS. A few apps like Office, Music stuff etc. All my Games and the Launchers are on a separate SSD.

Hope this helps.
 
Isn't that a bit high, even for RAID?!

Spec: All-new extreme data performance controller delivers up to 3, 480MB/sec sequential read, and up to 3, 000MB/s sequential write, for blazing fast read, write and response times
 
I'm now monitoring host writes and after a bit of tidying I'm down to a little over 1GB per hour instead of the lifetime average of 50GB+! :D

Now keeping a keen eye on prices for my next NVME purchase...

I have no idea sorry. :confused: That's just the results it gave me. Not running RAID if it helps.

Ahhh I wonder... I'm running AMD RAM Cache util. Could that be interfering with the speeds haha?
 
Just a quick update - after going through and stopping all instant game/replay capturing, processes and unnecessary programs I had my host writes consistently down to a very low level.

However, in the steam sale I purchased BF4 for a bit of fun. Had a go online last night and after a quick session, just 1 round on 1 map, it had made 300GB of host writes!

I guess I will have to keep games and OS separate. Maybe get a smaller NVME for OS / Applications and run current one into the ground with all my games - not sure yet...

Interesting! That kind of volume could see many drives not make there warranty period - E.G WD SN550 is rated for about 330GB per day under its endurance rating.

Does that write figure include downloading the game and unpacking it? Or just playing? And had you played those maps before at that patch level?

If you repeat the same thing today does it write another 300?
 
just playing - had it installed a while back and did a quick offline session before yesterday's online session. Could be something to do with particular map / first time.

Will try again tonight and post an update...

I personally always do this so that would be my recommendation. OS on the M.2 and then Games on a 1-2TB SSD. Even though most SSD's have the same read/write speeds nowadays you can still pay extra for one with better IOPS etc over another. But that way you can afford to have a smaller main M.2. As mentioned I have the 500GB MP510. Windows shows me 460GB usable. And with OS and Office and some other basic apps installed I have 383GB free. I then have a mechanical drive for backups / downloads / scratch area / etc.

I don't think I'd ever try and have Games on the same drive as my OS. That's just personal preference - may not work for everyone though.

Thanks.
 
Haven't managed to get around to trying BF4 again, will post update as soon as I do.

For many years I have had OS and select games on SSD without any issues regarding high write activity. Decided to splash out on a 2TB NVME so I didn't have to pick and choose games to go on it but then had this issue. I've done a lot of tidying and write activity is now at a very good level, even with many racing simulators and regular updates / mods. Now it only seems to be BF4 that is giving OTT use but guess other games that I haven't monitored may give similar results - will just have to keep an eye on it and if there's nothing that can be done, I'll put it on an old SSD for now or future NVME depending on the severity.
