SDHC substitute for SxS cards

[Ted OMalley]

It MIGHT work - if the listed specs are accurate. It only needs to be able to write at 5MB/s so support EX1/3 in HQ modes.

Does this Sandisk reader do the job? I don't see it mentioned among the posts (but there are a lot of them!): Sandisk SDAD-109R? I can't see the Kensington at B&H.

If that works and the door closes on the EX1 ... wow.

Is there somewhere ... please ...

a complete explanation about all these bits and bytes and MB and Mbit per second
and so forth??? Where can a read that a card matches the required specs or better said
is read and write speed in MB/s bites or Bytes, is the datarate in HQ 35 MBits or MBytes?

I am confused (and never was good at maths, I must admit).
Someone please enlighten me. Thanks.

all video rates are usually in bits (little b=little bit big B=big Byte).
1 Byte= 8 bits.
so 35Mbits/s= 4.375 MBytes/sec

Usually, capacity (size) of a device is expressed in Bytes.
so a sandisk card is 16GBytes running at 15Mbit/sec or 4.375MBytes/sec.
You still have to guess if the unit is described using 1000 or 1024 multiplier.....

anyway, even if you know all of this, it stay useless since experience shows that card rated at good values are still unable to function properly.

It is a bit like "lumens" or "watts" when applied to consumer electronics.
Marketing B.S is very creative at using science....

Peter,

You really couldn't find this information in this thread? It's been detailed two or three times in the past NINE HUNDRED POSTS! AAARRGGHHH!!

Seriously, though, this has become a cumbersome and even daunting thread for those stumbling across it to find out information. I suspect we'll need to answer many of of the same questions over and over.

[Ray Bell]

I know this question has been posted before but I still have not seen the true
answer... ( have seen workarounds)

The question is " has anyone found a card holder or case that is specific to these cards "


Thanks

Ah, les suisses. Ils savent comment expliquer une chose compliquee
en deux phrases. Merci Francois.

And for all those non-fracophonians: Appreciate such simple explanations and come
back for further explanations if necessary ;-) P.

Giroud you can't have it both ways.
You say
35Mbits/s= 4.375 MB/sec
then you say
15Mbits/s= 4.375 MB/sec

Which is it?

Ronn I think this is a typo and should read 35 MBytes in both cases.
Nothing else makes sense to me.

Greg - hey my friend I didn't know you had an EX1. Good to know if I need a 2nd - and vice versa. My contact info is at kilby-dot-tv .

As for this transcend 32GB card - why don't you buy one and let us know? :)

[Jon Sands]

That cards write speed is 8MB a second. Considering real performance is usually around 2/3rds of what's stated (the sandisk 15MB a sec are found to be what, 9?), that leaves no headroom whatsoever for HQ recording.

According to the specs, it can write at "up to" 8MB/s (and reading at 18MB/s) - I think the SDHC cards we're all using are writing around 6MB/s - so it sounds to me like it might work.

Good point Jon - guess we'll have to see.

Are the Transcend 32 Gb cards faster than the Lexar SSD Express 8 Gb?
