Delkin Black vs Delkin Power 4.0 Buffer Test

Delkin Black vs Delkin Power 4.0

Unscientific Buffer Test (Images Taken)

Setup: EOS R3 / H+ / RAW + LJPG

Delkin Black 106
Delkin Power 4 272

I will note that Black never hit the buffer in H RAW (1000+ images).

With an Angelbird AV PRO v60 SDXC sequential writing, the buffer hit at 120 (H+ RAW). This will probably matter more with the EOS R1 and the dual CFe slots for those that do crazy bursts.

I don't yet have a USB4 card reader to test an image dump (ordered). I do have the ASUS USB4 PCie card.

Disclosure: Delkin Devices sent the cards to me for no cost.

It’s nice to see that CFe4 cards also help performance in CFe2 cameras.

For me, I love how fast I can offload things to my computer, the prograde USB4 CFe reader has been working well, although I haven’t tested CFe4 cards yet.

One thing I don’t like is that card vendors only support their own readers for updating firmware and doing TRIM type of things.

I ordered the ProGrade reader... the OWC took longer to get. I don't think anyone else makes one.... not sure what Delkin is waiting on.

I also installed this into a computer: https://www.delock.com/produkt/91755/merkmale.html

That allows me to use the NVME tools under linux to inspect the cards. The downside to that: I'm using a consumer motherboard where PCIe hotplug doesn't work properly, so I have to reboot after inserting/removing a card

That's cool.... well not the reboot thing.

I have started using AtlasOS to avoid all of the crap Microsoft is doing to Windows. Hopefully they make an official no CoPilot in any way version. The uninstall is 368kb.... efficient coding!

If not.... there are lots of good Linux distros (using Mint on a laptop) that I may explore further.
