Zerene : to raid or not to raid ?
Hello everybody,
I’m collecting the components for the new computer for the stacking now and have a question :-)
Does the RAID-0 with two M2-SSD PCIe 4 make any sense? Is the performance significantly better?
BTW, I have already decided to Ryzen 9 3900

Actually I would like to know if RAID 0 is good for Zerene and LR :-)
e.g. it depends on the method of the reading of the CR2 and writing TIFF, etc.

I have had reports from users that RAID 0 helps with uncompressed TIFF due to the higher bandwidth.
In fact one user reported that large TIFF files read so fast on his system that he requested an option to write screen preview images as TIFF instead of JPEG. (That one's "on the list" but not done yet.)

Let's say your TIFF file is 200 MB. The write speed of PCIe 4.0x4 M.2 drive is around 5000 MB/s (ATTO benchmark on mine). So the writing of the TIFF file takes 40ms. If your software RAID were 100% efficient (which it likely is not), you'd get that down to 20 ms. So for 50 TIFF files you might save a total of 1s. I wouldn't bother.
Edit: I'll rephrase the last: I DIDN'T bother.

Depends on how you configure the system. I put system and programs on PCIe 3.0x4 in one M.2 slot and used the other slot for the even faster temp drive. Changing to RAID 0 isn't exactly an easy option now.Adalbert wrote: I will start without RAID but it is an option for the future :-)
Edit: The correct write speed was actually 4000 MB/s, not 5000.
