SSD Slowing Down Under Load

[BatchTheBrit]

System Specs:

CPU: i3 6100

GPU: RX 480

MoBo: ASUS Z170-P

PSU: Corsair VS450

RAM: 8GB Corsair Vengeance LPX (single stick to allow future upgrade)

SSD: Kingston SSDNow UV400 120GB

Case: Thermaltake Versa H24

Windows 10 Pro - 64 bit 

 

I have plans of putting a 2TB storage drive in there later on this month.

 

Anyway, I tried to record gameplay using Dxtory and I noticed that after a few seconds the video would cut down to about 8fps considering i had the recording limit set to 30. This was strange because I was still getting about 250fps in game so this was odd. Long story short, I benchmarked the SSD using CDMark and also the inbuilt benchmarking service in Dxtory. Both showed a similar issue. The SSD would run at about 400MB/s for about 5 seconds. It would then sharply decrease as time goes on. Looking at Task Manager while this was going on, I noticed that the slow down started the second that the SSD hit 100% load. This sharply cut my speeds and I believe this is the reason why I have had issues with recording. 

I currently have about 30GB free storage left on the SSD (as I said, storage drive coming soon) but I didn't expect the SSD to shit itself every time it gets under load.

 

What are my options? Can I fix this?

 

Cheers for any help and I have included screenshots of my benchmarks below.

 

 

 

Screenshot 1 shows the result from the CDMark benchmark.
Screenshot 2 shows a 1gb benchmark. I have noticed that in the time that it takes for this benchmark to finish, the SSD does not reach 100% load.

Screenshot 3 shows the loads observed during the benchmark shown in capture 4 which is a 3gb benchmark. Notice how the disk is at 99% load yet is only running at 60MB/s 

Screenshot 4 shows the result from the 3gb benchmark

Maybe look into trim? Or them other tips?

While I'm not sure what the problem is, I'd like to both say welcome to the forum, and thank you for being so descript!

It's quite rare for someone to have that much information when they have a problem, let alone a new member.

I'll look into some of those. TRIM is activated already so I'll have a look through. I'll also try changing the SATA cable and port that i'm using

Thanks! I have used other forums before so I understand the general idea is that you need to give as much info as you can so you can be helped!

I've had loads of issues with tech before so I know the procedure by now

Seems to be a normal problem! (I have an SSD since a few weeks, so also still learning...)

Am no expert, so some one that knows exactly might confirm or rectify the following if I am wrong, but think your specific SSD is not very suited for that specific use scenario with that small ammount of room left. Atleast I think thats going on

 

If a SSD is used constantly to write to (the recording) the steady state performance will drop significant over time. Since your SSD is filled up for around 75 +% it's good possible that on all blocks there is something written and during recording it has no time to manage it what results in dropping to a certain lvl of performance. Overall this is after several minutes, but depending on how much room there is left, this can ofcourse happen faster.

 

Your SSD is a budget SSD that for that specific task does not have the highest results. Very likely with the reasoning from above that this is the cause then. But as said could be way off.

I think this may be right as all of the other things I have tried to do have not worked. I will be buying a HDD tomorrow and i'll move most of my files over to it. I'll keep you guys posted on whether it helps or not!
