The Canon C70 is data-hungry whereas taking pictures 4K and particularly whereas taking pictures Canon RAW. Up until now, SanDisk has been the market chief in reminiscence playing cards. As a result of the earlier V90 SDXC lineup topped out at a measly 128GB capability, the appearance of Prograde’s $459 512GB UHS-II SDXC V90 has the potential to develop into the go-to selection for Canon C70 shooters.

I’ll be operating the ProGrade’s 512GB UHS-II SDXC V90 (hereafter known as the ProGrade 512GB V90 card) by a number of exams:

  • Double Test Capability – Does it certainly have 512gb of obtainable house?

In keeping with my MacBook Professional, the ProGrade 512GB V90 does certainly have the 512GB capability as promised by ProGrade. (Home windows units could return completely different outcomes). There may be nonetheless one thing wonderful about having 512GB of house inside such a tiny card casing, however maybe I’ll recover from that feeling because the capability of those playing cards is pushed additional and additional.

I’ll admit there’s a psychological hurdle with a card like this. If something occurs whereas filming 1920×1080 footage on a single 512GB card, there’s bother. The benefit to 128GB playing cards is that despite the fact that you could have to modify them each half-hour, there’s some consolation in figuring out you aren’t shedding the complete day if one thing occurs.

To assist offset any fear on my or your components, ProGrade presents free software program (with buy) referred to as “Restoration Professional” and “Refresh Professional.” “Restoration Professional” guarantees to get better misplaced recordsdata in your card ought to an unintended format occur or another sort of card difficulty. “Refresh Professional” is meant to optimize efficiency of your ProGrade playing cards.

Canon C70 Outcomes with ProGrade 512GB Card (RAW and XF-AVC UHD)

Once I first inserted the ProGrade 512GB V90 card into the Canon C70, I didn’t see a media warning. I took this as a great signal as a result of the C70 just isn’t shy about alerting customers when their media is lower than spec. A few of my older SDXC playing cards don’t play properly with the Canon C70. The rationale for that is that the digital camera landed through the shift to faster-and-larger-capacity CFexpress media. We C70 customers might need missed the boat on the CFexpress format, however that doesn’t imply the digital camera isn’t nice and price utilizing typically.

For me, having the ability to shoot the newly added Canon RAW ST, LT or trusty XF-AVC UHD codecs could be the primary buying impetus for the ProGrade 512GB V90 card. The excellent news is the ProGrade 512GB V90 card works with all codecs on the C70 as much as and together with RAW ST and LT, and also you get some killer recording instances with all that capability:

  • 171 minutes of RAW ST on the C70 at 23.98fps (Locked at 4096×2160 398 Mbps)
  • 263 min of RAW LT on the C70 at 23.98fps (Locked at 4096×2160 259 Mbps)
  • 166 min of XF-AVC YCC422 10-Bit 3840×2160 410Mbps Intra at 23.98

For comparability sake, on a 128GB card, we get 42 min of RAW ST at 23.98fps or 41 min of XF-AVC UHD 4K at 23.98. With the ability to report practically 3 hours of RAW ST on the C70 is an absolute delight regardless of my already expressed concern about placing all the pieces on one card. Personally, I’d go dual-slot report mode with two 512GB playing cards taking part in concurrently for actually mission-critical 1-shot content material, however that’s my paranoia talking.

It may also be value mentioning that Canon RAW isn’t my go-to selection for each circumstance, and this implausible video from Björn Kurtenbach utilizing the Canon C300 MK III (similar sensor because the C70) helps clarify why.

To place a closing bow on the compatibility query with the Canon C70, I went forward and burned by a 512GB card to see if there was a drop in efficiency or perhaps a heating difficulty. I’m completely happy to report there wasn’t a hiccup or warning indicator all through the RAW ST recording take a look at.

I used an AJA System Take a look at Lite to examine the learn/write velocity expressed in Frames/Second after which in MB/Second outcomes for the ProGrade 512GB V90. Once more, this software program is obtainable totally free right here. The system permits customers to foretell the capabilities of any drive system for recording and taking part in again numerous resolutions and codecs.

The cardboard was formatted upfront for the Canon C70, and all exams have been accomplished utilizing the ProGrade Digital Twin-Slot UHS-II SDXC USB 3.2 Gen 2 Kind-C Card Reader (marketed Information Switch Speeds as much as 1.25 GB/s).

The AJA System Take a look at Lite means that you can set a selected file measurement to emphasize take a look at. Commonplace UHD 4K and ProRes (HQ) look like a terrific benchmark. For tv, because of the 16×9 side ratio, I are likely to shoot in UHD 4K as a substitute of Cinema 4K.

Outcomes expressed in Frames/s.

Listed here are these MB/s outcomes.

MB/Sec outcomes expressed in graph type.

As you might already know, a V60 card will need to have a minimal sustained write velocity of at the very least 60MB/s to achieve a V60 classification, and a V90 card will need to have a minimal sustained write velocity of at the very least 90MB/s for a V90 designation. In keeping with the 2 charts above, we’re actually testing a speedy V90 card right here.

And here’s a Learn/Write 5GB stress take a look at utilizing Blackmagic Design’s Disk Pace Take a look at software program (Model 3.4). Once more, you may obtain this software program totally free right here to check your media at dwelling. The cardboard was formatted upfront for the Canon C70.

SanDisk 128GB Excessive PRO UHS-II SDXC Efficiency Take a look at Vs. ProGrade Digital 128GB UHS-II V90

Out of sheer curiosity, I made a decision to place the $149.99 (at present on sale down from $199.99 as of Could 2022) SanDisk Excessive PRO UHS-II V90 and the $149.99 ProGrade 128GB UHS-II V90 face to face utilizing each the Blackmagic and AJA software program.

Right here’s the SanDisk 128GB MB/s take a look at set to 4GB and with the identical decision and codec settings because the 512GB V90 exams (For reference, full settings are positioned on the left aspect of the screenshot beneath.)

Now for the Blackmagic Disc Pace Take a look at on the Sandisk 128GB MB/s.

Barely higher MB/s write outcomes on the Blackmagic software program versus the AJA.

And now we’ll give the ProGrade 128GB a glance. First, with the identical codec and backbone settings within the AJA software program:

A look between these outcomes and the SanDisk outcomes above lets us know that we’re touchdown in an identical spot with learn/write speeds. A guess on my half, however maybe because of this SanDisk lowered their worth to extra carefully match ProGrade’s present pricing.

And now the identical 5GB stress take a look at with Blackmagic Disc Pace Take a look at and the ProGrade 128GB:

Once more, practically similar outcomes with a tiny write-speed edge to the ProGrade 128GB. I additionally double-checked the capability of each 128GB playing cards, they usually landed on the marketed 128GB capability.

Lengthy-term reliability apart, from a pure efficiency take a look at standpoint, I might really feel very comfy with both V90 128GB choices from SanDisk or ProGrade.

Remaining ideas

As we proceed the transfer in direction of CFexpress, there are nonetheless a ton of digital camera platforms and even audio combine units counting on the tried-and-true SDXC reminiscence card.
