Which UDMA cards are you getting?

According to the reviews on Newegg, there's a guy there who found it to run at about 5MB/sec. So it sounds like your results aren't that far off. That Kingston is a "133x" card, and it's not UDMA.

Barry, could you please help me out. I am a bit confused. Did I not buy the card everyone is talking about? Do I have to check for a UDMA on the specs? I bought from B&H: http://www.bhphotovideo.com/c/produ..._32GB_CompactFlash_Elite_Pro.html#accessories

I'd love to know if I should order a new one from Newegg right now. Or is that one ALSO not the one everyone is talking about?

How much and where? Please. Thank you!

That's where I got mine. Now all I need is a camera to use it in. ;-(

Sounds like I am not alone.
 
But isn't everyone saying that they work with the 5D? Others are saying they work with their 7Ds...

I have 4. They have been running in two 5ds and two 7ds without issue. They all get between 10-20 MB/S on blackmagic disk speed test.

I have shot with these on my 5d for 6 months and have only dropped frames twice. Both times were when the card was about 90% full. Obviously, no one should operate with the card 90% full.

How are your offloading speeds? They would have to be the same as they benched so not much hope for an explanation for my issue there... time to RMA?

Here is the 4.1MB/s on HD Tach, which is the same with the card completely empty and with ~1.5GB of stuff in it.

(Throwing 1.5GB of data into it took close to 10min!!!)

And I also got 3.9MB/s on HDtune.

THANK YOU RYAN!!!
Your videos will not look better if you pay more for higher spec memory than you need. If it works it works....
You can argue future proof, but prices will MOST ASSUREDLY GO DOWN and the low end of the market WILL GET FASTER AND BIGGER before our little cameras get "RAW" video, or neural synaptic interfaces, or direct to MotionPDF, or Holographic 3D Liveview Recording (only 30p at first, WTF Canon!), or 3168p :)

But if you have the money for UDMA and feel more confident by using it, go for it.

This is ridiculous... I get UNDER 1MB/s on my laptop with the PCMCIS adapter.

Do I need to format in the camera? Could that be the issue? I formatted in the desktop (FAT32).

I put in an order for a second one from Newegg. At least I know that I'll be able to RMA with them till I get a good one.

Dude it really sounds like a bottle neck in your system somewhere, or, on a longshot, a driver issue

I was wondering but benching software uses nothing but the drive that is being tested and RAM. I have tested SDHC cards before and gotten over 10MB/s on the same reader on the desktop. I just ran one of them again and got 13.6MB/s minimum transfer. So anything below that rate can be attributed to this specific CF card sample I was so f'ing unlucky to get.

I hope that;s the case, I hope I just got a bad one. It seems many people on Newegg complained about slow cards. Usually, if you have a problem with something you just bought, you inmediately get online and whine about it. So I hope that there are many satisfied customers out there who might have gotten good ones and said nothing. Cause otherwise, based on Newegg reviews, there are a whole lot of slow ones out there.

Also encouraging is that many DVXusers seem happy with them, and have used them on their 5Ds, now some on their 7Ds I suppose. Unfortunately I can't remember anyone specifically stating they used this particular type of card with their 7Ds. If anyone does please let me know to give me a bit of peace of mind.

!#@$% B&H will charge ME for shipping back of the FAULTY card... stuff like that really stinks, no matter how little the charge.
 
I feel your pain... :(
Have you benched marked another CF card or just SDHC? Sometimes hardware/software(drivers) can have weird specific issues like that.
And yeah I think upset/dissapointed people have a greater desire to give a rating than satisfied people, so there's that
 
This is my first CF, I was an SD guy till now. I downloaded the firmware for the reader and tried again. Same deal. I will try to reformat in-camera as soon as I get it.

In the mean time all I can do is:

Why there's not such thing as rebates in Japan?! CF prices here are crazy. Fujiya, Map Camera, Yodobashi, Bic Camera, even the tinny little shops in Akihabara are charging double of what people are paying in the US. The cheapest place I found was Amazon.jp so I ordered a SanDisk Extreme III 32GB 30MBs version. Even though it doesn't say so on the card or package itself, this 30MBs is in fact UDMA as stated at SanDisk website. Hope it doesn't give me any headaches. Seems that getting a trouble free CF is like playing the Lotto...

If you want a fast compactflash card, you want the Hoodman or the SanDisk Extreme IV.

Barry (or anybody else), thanks for your thoughts on this... I found a Sandisk card that didn't say "Extreme IV". Almost pulled the trigger, but thought I'd just ask for opinions...

On first look, it's faster / cheaper than the Extreme IV and is UDMA enabled. It's over at eBay...

Whad'ya think?

Thanks,

First post. I have a few 8GB Sandisk Extreme III's 30MB and haven't had any trouble yet. I've only messed around with it a little. Maybe 20 min. total. I'm getting ready to order a few of the 32 GB cards but have been a little trigger-shy. Has anyone had any trouble with these cards and the 7d?
 
More dropped frames today... sCAN'Tdisk's x133 32GB's are NOT for pro use, period.

That is 4 times already and I got my camera less than a week ago.

I am returning them and getting something faster, 16GB hopefully.
