Patriot 16GB Class 10

Dylan Morgan · April 20th, 2010, 07:05 PM

I had a Patriot 16gb class 10 that failed on me... I retured them and bought 2 Sandisk 8 gb for $50 each-End of story. No problems and no heat. I'll never mess aournd with another card while shooting anything important.

How did the Patriot card fail? What were the symptoms? When did the problems start? In the camera? When transferring? Do you notice a difference in the heat of the card of the amount of times the camera overheats? Just trying to see if there is a pattern...

I bought a 8gb along with my 16. The 8 never failed, but really didn't use it that much. As soon as put in the 16gb I started to record random stuff outside and when I went to preview the file off the camera it said media error "cannot play file" or something like that. A couple of times it did record stuff but with HUGE glitches to the video and audio, rendering it usless. It would also stop recording without me pressing anything. I tested out the cam with taking multiple pics in a row to see if that would have any effect and it did. Multiple pics said "cannot view" . Perhaps it was just a faulty card, but it scared me big time. I'm shooting a wedding in a couple of days and cannot afford for this to happen. My primary is a EX1 so I'm safe.. No problems yet with the Sandisk.

Dylan,
what type exactly are your Sandisk cards?

Interesting Quote from the article "Information on the temperature operating range would be more valuable, for example." Which brings me back to to my original thought that this specific card may not be as heat resistant as others.

I still think my first card will be a Silicon Image. All the tests I have read say about a very good card. And is cheap. 40 euros for a class 10 card aren't much. And they test the class 6 here.

Silicon Power Class 6 SDHC, 16 GB

Silicon Power is a Taiwanese company that specializes in memory products of all kinds. We received a 16 GB SDHC Class 6 card; there are also 32 GB, 8 GB and 4 GB versions. Our card reached the maximum read speed of 19.7 MB/s, while also providing fast write throughput: we measured between 16.5 and 17.2 MB/s, which is an excellent result. In fact, this card offers the highest minimum write throughput of all the cards in this test, and is only beaten in the maximum results.

Also this white paper is interesting.

So how does one find out which card on the market is SLC and which is MLC?

According to this post Sandisk apparently is MLC:

Extreme III SDHC 4GB - SLC or MCL ??? - Extreme III Cards - SanDisk Community

And it looks like some manufacturer's put SLC right in their packaging:

Ok thank you, I will try that next time.

Dylan Morgan · April 21st, 2010, 10:58 AM

I bought the extreme 30mb/s. Doesn't this camera shoot over 35mb/s anyway?

George Angeludis · April 21st, 2010, 11:26 AM

Data rate and video bitrate are 2 different things.
HDV is about 25 Mbit/s (3.125 MB/s) almost as DV.
This should be around 5-6 if it is 45-50Mbit/s.

I got done a Wedding today and noticed that the Sandisk cards when swapping the cards were a tad warm. Towards the end of the event I used the Patriots and when swapping the 2 patriots I have left they were scorching hot. Very strange which brings me to my conclusion that these cards are not very tolerant to heat as the Sandisks. Probably the reason my first card died.

George Angeludis · May 2nd, 2010, 03:13 AM

I am convinced that everyone should use at least the Extreme III from Sandisk. I still haven't seen the 3.7 fps/sec rate. The 30mb edition.
