p.1 #1 · p.1 #1 · Z8 CFE > SD backup speed test


As has been discussed in the last few weeks, the Z8 presents a bit of an issue for folks wanting to shoot action/burst with unlimited buffer but also reap the benefits of backing up to slot 2. The proposed solution is a periodic Slot 1 to Slot 2 copy via the menus.

Test 1: Delkin Black to Sandisk V30 SD
370 HE* RAW images - 3min, 21sec

Test 2: Delkin Black to Sandisk V90 SD
370 HE* RAW images - 2min, 14sec

Control with the Z9, Delkin Black to Delkin Black
370 HE* RAW images - 29 seconds

Given the huge price difference between the V30 and V90 cards, I don't see a compelling reason to splurge for V90 unless you're shooting backup mode to them.

Yeah with this process just format the SD before each backup to the SD card and you won't have any redundant files eating up space on the card.

I lied, you CAN do a delta copy if you pick "skip" when running the second backup, but you have to manually hit "skip" on every file...I think formatting and rerunning the copy is the way to go. They need a "skip all" option like the "replace all" option.
