Hi,

I have a Panasonic HC-X800 Expert HD Camcorder and was wondering if anyone could tell me what the optimum write speed the camcorder records to SDHC SD cards. The reason I am asking is this that there are two speeds of cards I am looking at getting, the Sandisk 45mb/s & 95 mb/s (Class 10) and I need to know if there will be any benefit purchasing the 95 mb/s model ?.

Many thanks in advance !

If you use a USB 3.0 reader and USB 3.0 port on your PC or Mac the faster card will upload your video files faster.

Thanks Jogiba,

Am I right in saying the 45 Mb/s & 95 Mb/S is referring to copying from the camcorder to the PC as apposed to the recording speed to the card from the camcorder......I think that make sesse..........

It is easy to confuse bits and bytes or MBps and Mbps. I have to look it up every time I try to convert from one to the other.

The short version is that the camera creates data being written to the card. At the highest quality setting in an AVCHD camcorder, a Class 4 card is enough. A Class 10 card is three times faster at recording than the camera is at creating data.

Once the video data is on the card, we want to copy (or "download") it to our computers. You can buy the most expensive and fast SD cards produced, but most of us have a bottle neck somewhere. The camcorder plugged in via cord may be no faster than USB 2.0. Our card reader may be USB2.0.

Jogiba is saying that you MAY get an improvement in copy to computer speed if you can find a USB 3.0 card reader and plug it into a USB 3.0 port on your computer, if you have one.

I have a variety of Class 10 cards that are currently prices at about $25 for 32GB. (or is it Gb?). Never has copying to my computer been too slow. In fact, compared to all the other things involved in editing, copy to PC speed is the least of my concerns.

Good buys:

or even a little better:

Slight waste of money:

Gross and extreme waste of money:

I have used a Sandisk 15mb/s Class 4 card with my Panasonic TM700 to record 1080p60 28mb/s videos without any problem but today prices are so low I would stick with the 45mb/s cards or faster since thay are only a few dollars more than the slower cards and upload to my PC using USB 3.0 much faster.
