Is my hard drives adequate for encoding?

jriker1 · 27 Jan 2016

I have two 900GB 15k RPM 2.5" drives in raid zero in my system. Using PERC 600 hardware controller. I use the system constantly for encoding and wondering if I need to switch to SSD for the hard drives. On my system when looking at the disk stats for the encoding process, there is always a response time of 52 or higher. Sometimes goes up to 100+. I've heard anything over 20 is bad. From a disk queue length perspective those drives (D: drive) sit around 0 - .20 during encoding. Thoughts? Is it working OK? Is there something I can do to boost performance? Note the CPU's (24 cores) are running about 53 percent utilization.

Thanks.

Hi and welcome to SevenForums,
An ssd is one of the single best upgrades for a machine for sure

If you fill in your system spec's with the link above my signature will help others help you quickly so they can see your system with all of your posts :)

If you open a command prompt window and type in
winsat mem
Post what it says use that a couple times
Exit and enter after to close.

Never heard of a 24 core cpu :/
Use cpuid/ cpu-z and post the Main Board & MEM & CPU sections here
On the left side just scroll down a bit for the download setup English.exe
CPU-Z | Softwares | CPUID

Thanks for the reply. I have 2 xeon CPU's each 12 cores. Memory check returned performance of 12377 MB/s

For reference until I can get my stats in which I don't like to do since I have 13 computers at home, which one do you put right?

Dell Precision R5500
Dell Perc 6/I raid adapter
Display NVIDIA Quadro NVS 295
Processor Dual Xeon E5645
Memory: 24GB

Edit: Should be noted that I am using a plugin called NeatVideo. Very intensive but would think no matter what you use something needs to be bottlenecked, CPU, Memory, or hard drive. Graphic card I'm not encoding with so thinking it's not that.
Also outside of neatvideo, try other tools like Expression Encoder and getting 25% CPU utilization across 12 cores. Hmm, doesn't use both CPU's on this tool? Disk response time is 11ms and disk queue length at 0.07.

Thanks.

Just a little information. 12 threads per cpu not cores.
