Qimage Folder on HD vs SSD

« on: February 27, 2019, 02:46:52 PM »

Hi outthere,

I'm busy to configure a 'dedicated High-End Workstation' for postprocessing. I've an question; Does Qimage benefits from a SSD for it's data-storage or will a traditional HD be sufficient?

With regards, Martin

Hi Martin,
I've had an 240GB SSD C-drive for some time with a 1TB HDD D-drive for files.
Initially I ran Q with the Application Data on the C-drive but as the C-drive has relatively small capacity and as the App Data, particularly the raw cache built up, I migrated the QU App data to the D-drive. I do maintain the raw cache to reduce it now and again, but with it on the D-drive it is less critical to do that.
I did not see any slowdown of QU processing when the App Data was on the D-drive.
I think the factor that affects processing speed most (cache building and printing) is the processor and it's speed. Modern processors of a similar speed with 8 threads are faster than my 10 year old i7-3.5Ghz model.
Terry.

Edit: you could try both locations for the App data as it's easy to migrate using the QU Utilities feature. Time each various processes for each location. T

Hi Terry,

The candiate CPU is 8 C = 16 threads. (Frequency of processor: 3.6 Ghz, Turbo: 4.3 Ghz)
Of course I can try both, HD or SSD. But that isn't very operative, because I want to buy a dedicated drive for Qimage.

So I want to start directly with the right choice.

There are six drive bays (2 x 3.5" & 4 x 2.5") + for Lightroom Data; a PCIe NVMe 1 TB SSD.

With regards, Martin

Sounds like your processor is pretty good.
SSD's have a faster read write speed than HDD so if QU program and data and images are on SSD's, it should be the fastest option. I'm sure why it's necessary to have the QU program and App data on a separate drive from Windows?

Hi Terry,

My OS is on 'a second gen SSD', namely a PCIe NVME drive ((capacity: 512 GB, (NVME SSD can deliver speeds more than six times faster than the fastest SATA SSD's (up to 3,400 MB/s vs 545 MB/s, (HDD is 125 MB/s))
That's the same reason why Therry-M moves his files from a C:\OS SSD to a D:\DATA HDD. I'm going to move the files from C:\OS NVME to X:\{Qimage} SSD

With regards, Martin
