Microdrive vs. CF media

Someone has a site comparing speed on the D7i, and the Kingston
cards were among the good ones for that camera. 256Mb Kingston is
$110 at Buy.com with free shipping. I got two as I just prefer to
separate out my stuff to individual cards.
This is an important part in deciding; I prefer to have one big card that I never take out of my camera, some people want several cards.

If you constantly swap cards around the chances are bigger that something happens, like a card being dropped. Since MD's are more sensitive to physical abuse (although not much - when they're turned off they're surprisingly resilient) this is bad.
I think the microdrives are a lot more reliable than they were last
year, but I still feel more comfortable with solid state.
A lot more, yes. As long as you don't bang your cam around.
I think it is significant that most data recovery service companies have
added microdrive.
Yes. It means the CF Microdrives have skyrocketed in popularity.
Long term reliability data suggests the original
microdrives were not the most reliable of devices and seemed to
dislike high humidity.
Correct. The heads rest on the surface when the drive is off, and would stick to the protective coating. This has been fixed, the new coating doesn't stick.
Some cameras are twice as fast with the best CF cards than with
microdrive where on others the microdrive is the fastest. I think
it is worth your while to find out how it performs on your camera.
This is also important. Since MD's use more peak power (but not much more average power) and have different tradeoffs than EEPROM they can be faster or slower depending on bus implementation.

It's worth noting that EEPROM is also dead slow, so solid state CF's are in no way inherently faster than MD's. A spun up MD can deliver very high burst rates, and writing on a hard disk is potentially much faster than writing on EEPROM.

Plug a CF MD in a PCMCIA slot on a notebook and you'll see how fast it can really be - they scream when you do that.
Several microdrive devotees on the Minolta board say they leave the
drive always in the camera to avoid damage.
For convenience, in my case. Avoiding damage is a side effect.
A 1Gig download is
about 4 hours through the camera.
I have never filled the drive, but that figure does sound rather high. Of course, it could depend on USB implementation and drivers. If I had filled the drive that much I'd probably use the PCMCIA adapter to empty the card - it empties in a couple of minutes using that.

and remember...it isn't the drive's fault if the download takes forever...it is the USB port and software. When will we be supporting USB2 I wonder? Or firewire???

WTF?
 
Bought my first MD 2 days ago! Iomega branded from Staples - $79!

What a deal! NOT!

It crashed last night- second time I tried to download from it. Never dropped it, or damaged it at all...

Never again, though I hear the 1gb are more durable...
Hi, as for comparisons, I guess numbers do the math for us...yes,
the CF cards are faster than a Microdrive in write/read in Digital
Cameras...but I have a question.

In comparing a 512MB CF card to a 1G Microdrive...

Is having a CF card that is twice as expensive as a 1G Microdrive
really worth it...considering it is less than 1/3 more performance?
I know that 1/3 is a ton of performance...but come on...$600 512MB
CF or a $300 Microdive?

What do you think?

I here that iomega is the problem...not a good card.

Sorry...get what you pay for.

I understand that they are all IBM - just rebranded. Either way not worth taking a chance in my opinion.

The 4 hour guess was based on my experience with the CF cards. A full Kingston 256Mb card takes 65 minutes to download through the camera. Seems that would put the Microdrive in the 4 hour range.

The Kingston 256 card is faster at writing in the camera than the MD, but perhaps the MD is faster at writing from the camera to the computer. Or maybe my USB is just slow.

Reading from an MD, especially streaming, will be a lot faster than from EEPROM with a decent, high power driver. Some newer CF technology may be about as fast, or even faster, but in most cases you will get very good performance when pulling a sustained data transfer, the MD will be able to keep the bus full.

Random access is not as fast since then seek times start to matter; EEPROM has just about zero seek time.

I bought the Iomega 340 MB MD from Iomega in April. Took it on my photo trip to UT and AZ. Started off with it first every day, filled it then went to 256 MB CF cards. Used the reader that came with the MD each evening to load the photos into my laptop. Took over 2100 photos. On my G2, I could not notice any difference in speed from CF when shooting photos. I did notice it was a little slower going from photo to photo in play mode, but that's not what I do, so it doesn't matter to me.

It works flawlessly for me and I paid $68.00, no tax, no shipping and it came with a nice case and a nice PCMCIA reader also in a nice case. I don't remember exactly how long it took to download a completely full 340 MB MD to my laptop, but it was in the order of a few minutes.

Personally, I love it, and glad I got it. People seem to love to trash Iomega, but I don't have that problem. Ordered it on a Monday, it was at my door Wednesday. Sure it might fail, but I have already had my $68 worth of enjoyment out of it.

The poster who said the 1 GB takes about 4 hours to download - that's just plain crazy - there must have been some mistake.

As they say, "surely you can't be serious" - 65 minutes to download a full 256 MB CF card?? That's insane! Here is a test I made a short time ago:

I took a round of pictures, and just for fun, I measured the time it took to download them to my computer. There were 62 pictures, JPG SF, 113 MB (1.82 MB each, average).

PNV Compact Flash card reader on USB 2.0 port - 2 min, 20 sec or 2.25 seconds per picture.

G2 connected to USB 2.0 port using ZoomBrowser - 7 min, 20 sec or 7.1 seconds per picture.

My computer is 3 years old, 434 MHz, 384 MB, WD 7200 rpm internal disk, Win XP. Compact Flash card is Viking 256 MB.

My 256 MB card was about 1/2 full with 62 photos and 113 MB. So to transfer a full 256 MB card it would take about 5 min using the CF reader and 15 minutes downloading from the camera using ZB (compared to your 65 min).

You must have some REAL bottleneck somewhere! Plus, why EVER download through the camera. CF readers are SO cheap and SO simple and are MUCH faster.
 
I'm with you Gus - Iomega microdrives and IBM microdrives come out of exactly the same factory... There is no difference exceptt price. By the way, I see Ritz Camera still has some 1G Iomegas for $249 - a good deal and they will soon be gone (Iomega has stopped their line of M/drives).

How often do these microdrives fail? I have a digital portait studio and I can't afford to have my pix failing. plus is there alot of speed difference between CF and microdrives?
 
I have used a microdrive for over a year - no failure. I have also had a couple of mishaps with it - dropped it twice and still no problem. However, I do have more confidence in dropping CF cards (i have had one fall into seawater and it's till going strong.

Performance if Microdrives in write time is very good - better than most CF cards. See the reviews in the digital film comparison. The only time you see a slight lag is in playing back images- then there is a noticable pause. However, it's definitely not a disaster and the really key factor in speed for me is the camera getting the file onto the media - write time. For the price, microdrives are hard to beat.

I also have ridata 512 mb cards which are about the same speed (a bit faster); more expensive, but seem to be bullet proof. There is always risk - I suppose it depends what you're doing which could endanger your media. I find the accidents happen when I'm changing cards in a boat rolling around or putting my kit together on the kitchen table before leaving the house!

well I just ordered a Ridata 512 for $190 so I can't complain. I'm opening a digital portrait studio so I can't afford to have any failure from one of the microdrives. I guess I feel alot more safe with the CF.
Thanks for your input.

Interesting thread.

I'ved been using a 340mb MD for at least 9 months and it's been fine,
but I don't use it for anything that I can't afford to lose. For that
I use CF cards. The reason is that MDs are a mechanical device
and are more prone to failure from some sort of physical
action than CF cards are. And since I cover auto racing, and
shoot a lot of pictures, I end up changing cards during the
event, meaning more opportunities to mishandle something.

FWIW, I'm a proponent of using smaller cards, so that if I lose
a card for some reason, the number of pictures lost is limited
by the card size. The largest I have is the 340 MD.

I guess my advice is that for pro work, I'd go with CF cards
rather than MD.

--i have to agree with mr. gallo. i use 128mb cards, for the very reason he gives. if i would happen to lose a card, i at least have my images spread out over 4 128mb cards. i just recently spent two weeks in california, arizona and new mexico. i filled all four cards and transfered to notebook hard drive.

the notebook hard drive died! luckily i had left 3 of the cards as is. had deleted one of the cards, after dumping to notebook, and had it half full again. anyway, anything can happen. useing cp5000.
