Title: CF cards: how fast is needed?
Post by: Nick's Picks on September 19, 2005, 05:57:01 PM
I see a company on eBay selling dane elec brand 4gb cf cards for under $190
these cards are 23x 3.4mb min sustained write speed.

what does 24/96 require?

Hey Nick,
Here is a link to the core-sound site that would give you a ballpark guestimate.

Jace Nuzback is the product manager for the MicroTrack and he has returned a few of my emails... this is one of the few questions I can help you with! So here it is from the horse's mouth (I asked him the same question):

From all of the testing we've done, you should be able to use almost
anything.  Higher speeds are not required.

probably will result in very slow uploading, i'd guess.
hmmm....
I saw a 80x Transcend 4gb card out there someplace for $228.  now I cant find it again.
Almost a $50 difference vs nearly 3x the performance.

just for reference, 24/96 stereo data stream is approximately 0.55 MB/sec

So you're saying that a Kingston 45X (10mb read 8mb write) compact flash card should do it since it's 16x faster then the rate required for 24/96 recording?

(rhetorical question... don't answer)

Oh and it's $188 at Dell.

Maybe slightly related for selecting CF cards: anyone got info on various cards and their power consumption?

I could not get the circulating coupon code to work at Dells site.
I bought the cheap ass slow one.
it'll work just fine on the recording end.

The standard SanDisk compact flash cards work just fine in my R-1. I have been using 2gb SanDisks in my R-1 for what is getting close to a year now with no problems at all.

As I am writing this I am listening to the recording I made with the R-1 a few weeks ago of the Allman Brothers Band at the Fairgrounds in Essex and it sounds mighty fine.

I've got Best Buy reward zone money to blow so what exactly should I be looking for?  For an R1.

I had great success with the Kingston Pro Elite 4GB CF type I (45x) card in my Fostex fr-2. Relatively cheap too. I got mine for under 200 dollars.
Title: Re: CF cards: how fast is needed?
Post by: Nick's Picks on September 23, 2005, 02:31:58 PM
yea, thats the card to get in terms of price vs. performance.

but the matter is, what is the speed good for?
it wont write the data any faster than the resolution requires.
so its all about having a good usb2 or firewire CF transfering station?
Title: Re: CF cards: how fast is needed?
Post by: philb on September 23, 2005, 03:14:15 PM
I think you are right. There shouldn't be a problem as long as the card meets the minimum requirement for a write speed at the high resolution audio. Fostex has tested different CF cards with various speeds and they seem to work fine.

As already asked here, I'm wondering if getting something faster (for faster transfers) eats up battery life and thus it's better get a slower card.

Anyone?

Thanks

I dont think so.  nothing is "working harder", its just faster by design.
Title: Re: CF cards: how fast is needed?
Post by: janka on September 27, 2005, 05:41:57 PM
Nick, I'd also recommend the Kingston Pro Elite cards. Mine's been working great in the FR-2. I payed $220, shipped. I looked up the dane elec card on ebay.  I'd steer clear of anyone advertising free shipping and handling then charging $5 'shipping' to cover tracking and insurance.  ???

Post by: Nick's Picks on September 27, 2005, 05:44:35 PM
yea, i cheaped out..and got that slow ass 4gb DE and saved $30.
I should have bucked up...but its only the transfer speed that is affected so I said "eh"

I purchased:

Hitachi Microdrive 3K4
Model # HMS360404D5CF00
219.99 @ Best Buy

Performance     
Data buffer (KB)    128
Rotational speed (rpm)    3600
Latency (average ms)    8.33
Media transfer rate (max. Mbits/sec)    57.1 - 97.9
Interface transfer rate (max. MB/sec)2    33
Sustained data rate (MB/sec)    4.3 - 7.2
     
Seek time (read, typical)
   
Average (ms)    12
Track to track (ms)    1
Full track (ms)    22


---------------------------------------------------------------------------------

Not really sure what all of that tech jargon means but the 2gb discs they had in stock were around $280 so I was glad to get this one for so cheap.

Me being in a hurry I didn't read the manual fully and missed the blip about microdrive cards not working with the R1.  Fantastic, now I'm pressed to find one at wal-mart or office max tommorow.

It was posted on oade that slower CF cards got much better battery life in the R1.

Right, faster equates to higer drives on the logic inside the the flash for address decoding and output drivers. Higher speed flash also has better difference amps for detemining bit values too. Faster=more power for writing and reading.

P.S. Larger sizes require larger decoders so smaller cards require less power for reading and writing too.

Yeah, I returned that thing and ordered a 4GB Kingston flash card from Newegg.com for 211.00
Title: Re: CF cards: how fast is needed?
Post by: sunrisemusic on October 01, 2005, 10:03:39 AM
thanks for the speed/power use info guys.  Sounds like 40x or 60x is the go then.

Hi,
Anyone got any user specs on Transcend 80x cards? There's a special going on them in Japan (where I am).  Still probably not as cheap as the Kingston cards, but cheaper than Sandisk Ultras.
Thanks!

fwiw, the Dane Elec 4gb card would not work in the PMD 660.
:(
Title: Re: CF cards: how fast is needed?
Post by: esteyes on October 17, 2005, 03:28:37 PM
it is not just the write speed... the card has to be able to do SUSTAINED writing. i have a PMD 671 that writes fine to my basic ScanDisk 4G card but I cannot get either of the two 4G Delkin cards to write w/o a short 1-2sec burst of static on my recordings - VERY FRUSTRATING. talked to Delkin today and their answer is that they only expect their cards to write in bursts, not 4hrs of constant writing as is happening w/ CF recording.

Marantz only recommends Lexar (the priceyest but the most reliable), PNY, Viking, Hitachi, and IBM. (the last two are only microdrives, i believe and they do NOT work well in my 671 - see the marantz thread in this section)

neil in san marcos
i have two 4G Delkin cards available for sale, anybody want'em? they test at 5000+ kbps in the marantz...

Thanks for the tip. I just picked one up. $229.35 including 2nd day shipping. May need it this weekend if I go to My Morning Jacket instead of seeing the Illini get destroyed by Penn State at homecoming.

$211? The website shows over 211

They increased their price?
