Compact Flash Card

Hey there quick question for ya,

I have right now a 1Gig 48x Compact Flash card. I, for other reasons, have to buy another compact flash card. What I'm curious of is, if i were to buy a (lets just say) 4x CF Card, will this greatly effect the transfer rate?

I guess the real, real question is, what is the fastest CF card that the Fantom can read. If I buy an 80x Card, will that be overkill? I don't know the read speed.

Thanks guys,
Jason

Here is an excerpt from a digital camera website that tests CF cards:

http://www.dpreview.com/articles/mediacompare/

What's an X ?

"Lexar recently released their new 16x flash media, in that press release they clearly stated that an 'x' = 150 KB/sec. This means that the Lexar Pro 16x card should be capable of 2,400 KB/sec, and that the Pro 12x card (tested below) should be capable of 1,800 KB/sec. Unfortunately what they don't state is how they come to this figure, whether it is read or write speed and in what device the tests were performed. Until manufacturers come up with an independently verifiable standard test for transfer speed the only reference we have are our own tests (below).

As you'll see there's a big difference in performance depending on the device driving the card, don't buy a 12x card for your Nikon Coolpix 995 and expect to get 1,800 KB/sec, you won't."

With this in mind the Fantom-X reads data at about 400kBytes/sec. In terms of "x's" that would be 3x so theoretically a 4x card should read/write fast enough.

You can always do what I did and buy stuff and return it if it doesn't perform fast enough.

MIDIguru, it that mean that loading of 512 mb samples will exist about 20-25 min?

Could someone explain me which is the highest transfer rate obtained (in practice, not in theory) when loading samples into the FX ?

I ran several tests when I first got my Fantom-X with both regular Sandisk (16x) media and Ultra II and they were both in the 400-500 KBYTES/sec range which would be an equivalent speed of about 3x. Pretty slow given the potential speed of both of these types of cards.

Must be really slow hardware that Roland is putting on these boards...

"With this in mind the Fantom-X reads data at about 400kBytes/sec. In terms of "x's" that would be 3x so theoretically a 4x card should read/write fast enough. "

I read this forum today just after I purchased the SanDisk 1.0GB Compact Flash card. I understand that this is a 4
x read/write card so I should be ok with it because the Fantom XR will not read/write faster regardless of the potential speed of other Compact Flash cards with higher read/write rates.

I'm free to ask again: how much time is needed to load 512 mb samples in RAM memory? I didn't see precise answer.
Thank you
Zeljko

20-25 minutes.

1024bytes(number of bits in a MB)
X512(capacity of card in MB)
/400(lower tested transfer in kBytes)
/60seconds=21.84533 minutes

assuming a constant 400kBytes per second

man, that's a ton of samples for one project
