Ni idea sorry but those cards are interesting indeed.

My daughter is bringing two of these 32GB SDHC-II cards over with her at Christmas time. Toshiba handed some out to professional photographers at a trade meeting. One of these is a friend who only uses CF cards, so he is passing them on to me. I just hope they are not dummies :eek:

Formatting with SDFormatter was recommended by Thomas Overgaard for speeding up the start up and write times in the M 240.

 

Can't say I noticed any difference, but I only use Sandisk Extreme Pro 95MB/s cards in mine and they are fine.

 

The thing to watch for lockups is the little write protect switch which can move and lead to all sorts of errors...

eyefi pro x2 8gb class 6 - 1.5 seconds

 

Before running SDFormatter:

 

Sandisk 16gb class 4 15mb/s - 4-5 seconds

Sony 32gb class 10 - 4-5 seconds

 

After running SDFormatter ( quick format ):

 

Sandisk 16gb class 4 15mb/s - 2.5 seconds

 

Sony initially climbed to 7 seconds but came back down afterwards to 4-5 seconds

The 32GB Exceria Pro cards that Toshiba were handing out at the press launch were sadly publicity dummies, with just 256K capacity on them. I got my friend, who was at the launch, to try and format them before he sent them over to me, just to check if they were functional.

 

Damn - I thought I had two free super high speed 32GB cards on the way to me - TANSTAAFL :(

So are we saying the 64GB Sandisk at 95MB/s is the fastest card we can use? If so, I'll get one right now... Currently I use 16GB 45MB/s cards, and they make me miss shots when the camera has to boot first... either from sleep or fully off!

 

Something I never had with the M8 or M9!!

I just looked up the Toshiba card and I found the following.

 

Read/Write speeds depending on the SD buss/interface (see attachement)

 

Now I'm questioning what ''SD Bus Interface" the M (Typ 240) has, would it even actually be able to use the highest speeds or would it just be stuck at 95/90?!

 

Here is the website where I pulled the info: http://www.toshiba-memory.com/cms/en/products/sd-cards/exceria/exceria-pro.html

Having got over the disappointment of not receiving the free Exceria Pro cards, I am about to stock up on new cards and throw my oldest ones (mostly 8GB SanDisk Ultra) away. I understand that after a considerable number of read/write cycles, these cards become slower and more error prone and it is a risk I am not prepared to take, given the current price of memory media.

 

I have been offered Sony UHS Class1/Class 10 94MB/sec 16GB cards at the very good price of £14.56 each from a reputable UK dealer (i.e. not Fleabay). As this is less than 50% of the price of the comparable SanDisk Extreme Pro card, I was wondering if anyone had tried these Sony Cards in M8/9/240? As a relatively new player in the SD card market, having finally given up on their out-of-step Memory Sticks, it could be that Sony is pricing very aggressively to get market share. Given the reputation of Sony, I cannot see there being a problem with the cards. They actually look suspiciously like SanDisk cards with a Sony logo on them.

Pls see my report above on the 32gb version of this card. It was much slower than eyefi and Sandisk.

Given my experience with Sony memory media so far (DVD blanks, MS memory cards), I would not touch these with a long pole.

My post from a week ago partly covered this.

 

You absolutely need, with each card, to have re-formatted the card either in-camera or with available on-line software, in my case, it's from Scandisk. I use the in-camera for ease of use.

 

Please re-run these tests with a card you have just re-formatted in-camera. Your results will be vastly different, and in particular, the start-up time.

I use 64GB ScanDisk SD Ultra, their middle of the road cards.

 

……………………………………………………………………………

 

Do we know the difference between the SD and Compact Flash speeds, like for like, i.e., a 64GB ScanDisk CF Card " V" their 64 GB SD card?

 

……………………………………………………………………………

 

 

After a double-take, I now see the Toshiba card is not, after all called the "EXCRETIA Pro".

buffer continuous frames speed:

 

One day I was reading all that here, but think I did not read what I discovered right now.

Forgive if I repeat something said already.

 

Only shooting RAW, I'm not sure how that applies also to JPG shooters.

 

The buffer continuous frames burst rate is, aside what have been said, very much depended on the ISO settings. Switch to 1/4000 and eg ISO 4000 and test, and then the same with ISO 200...

When you know you know... of course the more noise will create a larger or more complex file and that will be the reason...

OK,

 

Came back from Istanbul with two SD cards, 1. Sandisk Extreme Pro 16gb and 2. Panasonic Exercia Type 1 32gb.

 

Both card started within 2 sec after formatted. However as the capacity was getting filled. Especially toward 90%+ capacity, start up time with both card started lagging significantly. Sandisk took as long as 3-4 sec and Exercia took as long as 5-6 sec.

 

So the start up time is not only dependent on the card but also amount of data that is stored in the card as well... There were handful of shots I missed because of the start up delay once the card got full....

That is unacceptable, and in my opinion due to the firmware using a pessimistic allocation technique in order to cover their lack of knowledge of the protocol. Who writes this s##t?
