Games on ssd still stressing hdd?

idontevenknow12 · Oct 19, 2016

I'm at a complete loss as to why this is happening. This is an issue I experience with all games. I have made sure that all of the games files are stored on my ssd, with no game files remaining on my hdd. I get brief/severe frame loss every so often when playing games, and performance monitor shows my hdd at 100% while ssd at 0%. My OS is installed on my hdd, along with miscellaneous files, so I expect this has something to do with memory caching. Although I find it quite odd that task manager is only reporting my hdd in use while I have a game open.

Did you install them to the SSD? What do you mean storing game files on there? And your system files/memory cache are going to play a big part no matter where you install games.

For best performance, you should install the OS, applications and games you play on a regular basis on an SSD. Completely. Without files being scattered all over various disks. The things that are acceptable to remain on your HDD are music files, video files, documents, archives and game installer executables / archives.

Yes, I mean exactly that. CS:GO for example, all of it's files are on my SSD.

herrwizo :

SSD space is at a premium. While I'd love to have everything on SSD, I simply don't have enough space. On top of that, it's a massive pain to move windows. I wouldn't say files are scattered. I simply have games, OBS, and its video folder on SSD.

It could be a power saving feature of the disk or in Windows settings. What model SSD is it? And what hdd/system?

Most gaming will be cached by the OS though so you could have a bottleneck going on etc.

Intel 750 PCI-e raid 1

Is this possibly happening when the game is hitting an auto save point? If your OS is on your HDD have you changed your documents folder to be on the SSD? By default it is on the HDD and the game could be reading from/writing to the HDD when it autosaves.

Well I am not surprised a WD Blue can't keep up, and could be the source of your problems maybe. One of those PCIe SSD's is sharing the x16 slot with the GPU also, and that GPU is dual so will probably need more than x8.

I would ideally try having your OS/system on a faster disk if possible. Also, 760w PSU may be struggling to keep up. What does HWMonitor say?

One of the SSDs is on a 2.0 x16 slot. From what I've been told, there shouldn't be any issue with that barring the decreased speed from the 2.0 slot. Total wattage under full load is a hair below 600w, and its a Corsair ax760i, if that PSU can't handle it, I'm not sure what could.

I read a lot of conflicting things when building this. I wasn't sure if I could have an OS on a disk in a raid configuration, which is why it's sitting on an hdd in the first place. Is the WD Blue that bad though? I've used it on previous builds with no issues.

Yeh you can have a RAID disk with an OS on but you have to create the array in your BIOS/with a controller before installing. Those Intel 750 PCIe NVME's are quite temperamental when it comes to RAID and Windows though from what I've read, especially with older chipsets. According to the spec that board's 3rd PCI slot is PCI 2.0 x4 which is 2gb/s. The disks read rate is 2.2GB/s though. Does it ever show usage or does it always stay on 0%?

The minimum recommended PSU for that GPU is 750w so it's debatable, but I agree it should be ok and you have pretty much the best model on the market. The WD Blue is fine normally but has about 100mb/s MAX read rate in real life and your OS probably needs to cache a ton to keep up with the other high-end hardware.

Yeah, the disk shows usage. I have a fair amount stored on it. I easily put around 5-10gb of recorded videos on it each day. I did some tests a while back to see how fast an old bloated Skyrim save would load compared to an hdd. So, I know it's getting used. I guess the HDD is just choking the OS. I have a lot of unused SATA 6 ports, Do you think something like an 850 would solve the problem?

It definitely could, but it would be a shame to spend the money on an SSD if it didn't so I wouldn't like to say for sure. Those PCIe disks also have an idle mode so it could be they are falling asleep (waiting for the WD Blue to catch up ha), and some sort of PCIe slot power saving thing going on, as I know you can set the slots to allow system wakeup etc.

Sorry I couldn't be more help. Is definitely a strange one.

Use Resource Monitor to see which process is accessing the disk and which files are being accessed. This should help you resolve the problem.
