For those complaining about the Komputerbay memory cards: DO YOUR RESEARCH. It clearly states on the product info that the 128GB cards have slower write times than the 64GB cards. Don’t just blindly buy any card that says 1000X, that rating comes from the READ speed, not the WRITE speed. (as it has since I’ve been using CF cards on the original 5D)
I have a 64GB Komputerbay card, I was originally a skeptic but, it works just fine. I’ve already shot over 256GB of RAW video with zero issues. The 64GB card is the one to get right now. If you need more space just get a couple. If you need to do single clips longer than 64GB in size…you would probably be better served by the crappy on-board video.
Also, these cards seem to use the same chips as the Sandisk ones…so enjoy paying for brand names.
The place where I ordered my KomputerBay advertised a "minimum 90MB/s write speed", which was not accurate and I am returning it today. No big deal. On a side note, James Miller shot part of his "Genesis" video using this card (shooting 1920 x 720).
I ordered a Transcend 1000x 128GB about 10 days ago. It just arrived. The fastest write time I could get was around 83MB/s. It's not useless, but it won't get 1920x1080. I'm returning it today. No big deal.
Fortunately, I have a Lexar 1000x 32GB and a Hoodman 1000x 64GB, which both write in the low 90s. Next up for me is a KomputerBay 1000x 64GB (probably sold out most places by now). And then I'll be on the prowl for a Toshiba.
Wow, that sucks! What site was it? Amazon lists the write speeds, thankfully, or I would've suffered the same fate! I almost pulled the trigger on the 128GB until I saw that.
I'm hoping fast cards come down in price soon, I have an 8-day climbing trip to Canada in two months and I'd like to be able to shoot more than 7 minutes of RAW video! lately I've been just lugging my laptop along and transferring to it as my one fast card fills up.
I keep shooting 1920x720 on accident, I wish the ML firmware would default to 1920x1080 instead of 1920x720...oh well, beggars can't be choosers!
There are definitely fast, bigger cards (Transcend) but I'm trying to save up for a new wide-angel prime so I'll hold out for now! (I'd feel like a chump paying over $300 for a freakin' memory card!)
I thought you could get a bit less than 15 min on a 64GB card....?
