I bough a Lexar Professional 1000x CF card in both 16GB and 32GB. Both cards seem incredibly slow when writing from my D800 to the card, even when i download the photos to my computer with a USB3 reader I only get about 10mb/s downloading but I get 70mb/s in the same reader with my 16GB Sandisk Extreme Pro CF card.
I dont get it, is the Lexar Pro 1000x not suppose to be very fast ???
I have to agree with you that is slow; there must be something wrong somewhere. I use a SanDisk 32GB Extreme Pro that is supposed to be 95MB/s and a Transcend CF Card 600X 16 GB and they both download at 35MB/s on a USB3 card reader but I only have USB2 port on my computer. Have you tried another port on your computer to see if it makes any difference? Mine download very fast in the camera, fast than my old D80.
Where did you get the cards, they are not a knock off cards are they. Only asking because seeing a lot of people finding out they have these card off EBay and other places. One Nikonian lost all his pictures a while back. If not I would check the card reader and computer and see if there is a problem with one or the other. Do you have another card reader you could try?
I have 2 Lexar x1000 cards and they are like lightning. I would have suggested that it is a card interface problem with a USB3 card connected to a USB2 reader, but you have covered that. Have you tried the camera tethered to the PC to eliminate any card reader issue and see what the transfer speed is then. The Lexar x1000 is recommended by Thom Hogan as possibly the best card for the D800, so I think you may have a faulty card.
What worries me is the slow transfer from camera to card and I cannot think of anything that would slow that up. I shoot in NEF 14bit uncompressed and it's still like lightning compared to my Sandisk Extreme 3 cards.
If the card was bought from a reputable dealer then they are guaranteed and should be replace.
The thing that worries me is that I have the exact same problem with both my 16GB and 32GB card (I have two of both) I am wondering if I was sold counterfeit cards. I bought them from B&H and the cards and the package they came in look legit.

I tried using an older Lexar Professional USB 2.0 Card Reader that works perfectly with my Sandisk 16GB and 32GB Extreme Pro 90MB/sec. cards and it would lock up the computer when I tried to download even a single Nef file from a 32GB Lexar 1000X card. Once I put them in a Lexar Pro USB 3.0 Card Reader they worked perfectly. I noticed on Lexar's website that they had a firmware upgrade for older Pro USB 3.0 Card Readers that was required to read the 1000X cards. Before you send them to Lexar, you might want to try using a Lexar Pro USB 3.0 Card Reader with the latest firmware. Good Luck and Enjoy your Nikons!
I contacted Lexar support, they said they I need to send them my cards and then they will test them and decide if they will replace them, in the meantime I will be without 4 of my very much needed cards for up to 21 days.
I think i am going to try and have B&H replace them with sandisk cards because Lexar sucks!!!!

I know this has been beaten to death, but unless you shoot very long bursts, you just don't need the 1000x cards. I use a backup SD and primary CF (which means twice as slow), both medium speed, and it's rare I hit the buffer limit. Obviously your mileage may vary, just saying if you are replacing cards, my experience to date is big is better than fast with this camera, if you don't want to pay for big and fast.

I totally understand what you are saying and I do agree, but my main problem right now is the fact that the Lexar 1000x is downloading to my computer at 11mb/s ... that is pretty slow and a pain if you come back from a wedding with 6 memory cards that you need to download to your computer and the Lexar card takes 15 min to download wile the Sandisk takes only 5 min.
Very weird, tonight I decided to format the card in my computer and to download a 3GB file to the Lexar card, it was uploading at 55mb/s. When I tried to download the same file back to my computer it was downloading at only 4mb/s

I am using Delkin Devices CF cards, and they are FAST! Bought from: B&H I should add: My card reader is a Sohouse USB 3.0 universal bay mounted unit. I have had no problems so far with the cards or the reader.
I bought a package of two 32GB Lexar 1000x cards and my only complaint is that they are not big enough for my D800. They do make a noticeably difference in camera and upload extremely fast thru the Lexar USB 3 reader.
