7D II memory card comparisons

My cell phone is used to make phone calls. Are you saying it is possible to work with matrices, diffEq, or third-order equations on a cell phone? I truly am a dinosaur.

A quick Google search says yes. A separate app for each possibly and nothing I have tested, but yes.

Here's a selection of cards that, over the years, have been demoted from the camera bag to the bottom of a draw...

That's too cool. I remember when 128MB came out and thought wow this is the future (like when they came out with 1GB hard drive lol).

I do agree, CF isn't going anywhere. A lot of industries and application use them for their ruggedness. We buy CF's at work all the time at our company. If anything they'll just pack more memory in the future.

I'm pretty sure that Wolfram Alpha can do some of that.

The phrase "you get what you pay for" is a cop-out and usually wrong, especially with memory cards.

Shop around, look for sales, keep the merchants on their toes. Read reviews and avoid high-priced junk.

Good point. I stand corrected. Those cheap Lexar's were very slow basic cards. I knew that going in. There was a reason why they priced that way and I was looking for that.

Yepp, $2.99.

Did a little testing today

Testing

- Lexar Pro 800x UDMA 7 CF 32 gig
- Lexar Pro 600x SD 32 gig

- Sandisk Extreme Pro UDMA 7 90 MB/s CF 32 gig
- Sandisk Extreme 45 MB/s SD 32


With these 4 different cards (2 CF, 2 SD) I got pretty consistent results. My test was to see, how many shots could I take until I hit the buffer.

The Results:
- any card in by itself, I could get 21 - 22 Raw files
- with any CF and any SD card in together, I could get 21 Raws on both cards
- any CF and any SD card in together, I got a range of 16 to 18 Raws on CF and Jpegs on SD
- the above results was consistent whether the Jpegs were L, M or S (this surprised me a little)

I was in a store today and tested out the 1066x Lexar Pro CF cards to see if it made a difference - it did not appear to when attempting to see how many RAW files you could get before the buffer was hit - 21 / 22 seemed to be the number - so I'm not sure if anything above 800x matters if that is the primary test. I didn't get deep into could the buffer release faster with the 1066x card versus the 800x.

I have a few cards on order for Black FRiday to see if a faster SD card will make a difference with shooting Raw CF, Jpeg SD - but I don't think it will as the existing 600x SD cards can get 21 RAWs before the camera's buffer is hit.


To the person saying 40 Raws - did you check your card? - because the 1066x CF card in the store after repeated attempts gets 21-22.

After doing this testing, I am going to change the way I shoot from Raw & Jpeg to either RAW / RAW or Jpeg / Jpeg as the hybrid setup just takes away from the camera's performance - and it seems like a smarter idea to decide before you start shooting whether you want to get Jpegs coming out of a machine gun forever or 20-22 RAWs with short pauses for a reset.

Paul, nice commentary and testing.

I think the (this surprised me a bit) thing you ran into is because (guessing here) the JPGs must be: processed before being written to the card. Processing takes time. It is not simply a matter of writing small files to the card. I ran into the same thing testing cards in my 6D. Raw & S3 (720x480) hit the buffer at the same number of shots as Raw & JPG-Large.

Oh, on my 6D, the buffer does clear faster with faster cards. May apply to the 7D2, also.

For Android there are free applications emulating later HP calculators, like the HP48SX. They do the tricks mentioned above.

My watch actually has a circular slide rule around the face. And it's not old at all.

I had no idea. Very interesting article here.

I have not worn a watch in over 25 years but this would make me think about it just for the fun of having a slide rule on my wrist.

Well, maybe not. I could by a lot of lenses for that.

I'm not one hundred percent sure but about fifteen years ago the price of cards were about $3.00 per
MB. So today a 64 GB card would only cost you $192,000. How times have changed.

I still use my HP48GX, all 128K of it.

Just did some more testing.

My 1066x 32gig card arrived today.

On its own, no SD card in the slot, I was able to get 33 RAWS - this is clearly more than the 800x.

I also got at 95M/s SD card and on that card I was able to get 22 RAWS just using that card.

Using both cards on RAW, I few times I got 27 RAWS but often got 22 also.

For kids sports I may switch I just the CF 1066x

Paul

For me it's more than just the number of Raws it can take before hitting the buffer; it also needs to clear the buffer quickly, so that I can continue shooting.

Paul, can you please elaborate on which camera and lens combo you used and the exposure setting? As you know all of these makes a difference.

Thanks...Al
