Does anybody know how fast the 10D can read/write to a card? I wondering if the camera can take advantage of the additional speed provided by the SanDisk Ultra II or if I should just buy the standard SanDisk compact flash?

It can write/read as fast as the Card can

I think the 10d would max out at about 60x. The 80x cards that are coming out are a bit of overkill for most cameras.

Read/write speeds for the 10D and various compact Flash cards can be found here.

There is really very little difference in performance between the very fastest cards, but a very significant difference between the mid-range cards and the basic cards. The Ultra II is a very good choice, giving you top performance without the very significant added cost of the "extreme" performance cards.

The tested speeds on the 10D are obviously nowhere near the rated speed of the card. You'd get considerably faster transfer rates from a Firewire card reader. FWIW- the Ritek 52x 1Gb card is $165 at NewEgg.com, and the SanDisk Ultra II 2Gb is $380 at computergiants.com. Happy shopping.

I have been using a firewire reader for download. It drove me nuts waiting to download even a 256MB card with USB 1.1

I hear ya! I took the USB cable with me on a vacation in May, and it would take 30 minutes+ to download a full 512MB Transcend CF card. Last weekend, I brought a Firewire reader & laptop with me to a wedding to clear off the card. That worked out great, and I captured 800+ photos in about 5 hours.

I'm looking at buying the Hitachi 2gb microdrive. Does anyone know how this compares with the best? Not just transfer speeds, but reliability, build, etc. I already have an IBM microdrive (which is pretty quick in my books) and just bought a Magicstor card with my 10D - but it's been giving me a lot of problems and I was going to exchange it for a Hitachi.

The link kirbic gave earlier lists the 1 and 4 GB Hitachi Microdrives.. I guess the 2GB will be similar.

Hitachi bought the Microdrive business from IBM. The hitachi & IBM products are one in the same, FWIW.

That's pretty slow. May have been something other than card r/w speed and/or the USB cable slowing your transfer.

Unlikely. I was transferring directly from the camera to an iBook over the USB cable. All software and firmware was up to date. I bought the iBook specifically for this purpose just days before, so there was no other software or system clutter to interfere. I get similar results on my other computers at home. The Firewire card reader is SOOO much faster!

A half hour to move 512 to your computer sounded awfully slow to me so I did a test to see if my frame of reference was correct. All of the equipment I used is older than yours. My Canon Pro 90, using the USB cable and software that came with it and an Canon CA-560 AC adapter, will empty a standard Sandisk 256 in a bit over 10 minutes (3 runs averaged 10:08). I'm told that Firewire is faster but USB isn't that slow if everything is working correctly, at least not by my test.

USB 1.1 or 2.0?

I'm not positive but this camera came out at the end of 2000 so I am assuming USB 1.

I tried using the USB cable that came with the camera and it was SLOW. I think I shot in RAW mode which is also not advisable over USB 1.1 at all. I bought a Lexar FW reader from B&H and it's amazing. I haven't timed it yet but it's very fast when I want to copy over my filled 512MB CF cards and I haven't completely filled my Microdrive (4GB) yet but I have come close. If you do not have a USB 2 or FW reader, I highly suggest one of them especially if you shoot RAW or have large CF cards.

I really like my 4GB Microdrive a lot. My favorite feature is the sheer capacity. I can shoot all day in RAW mode and not have to swap cards. On the last trip to Vasquez Rocks, I filled both 512MB Lexar cards and switched to the Microdrive for the rest of the day. Lexar 40x cards are fast. RAW files are written in a couple of seconds.

My least favorite feature of the Microdrive? Write times in camera. Since I only shoot in RAW mode the files are rather large (6-8MB each) and they take a while to write. If I were to guess how long, I'd say about 7 seconds or so. Again, I haven't timed these write times and they are just a best guess.

So, to answer your question, I feel that the Microdrives are built well and are fairly sturdy. I have dropped the FW reader with the Microdrive still in it and mounted on my Mac's desktop. Nothing happened. Was I lucky? Probably. Would I do it again? No way. Just wanted to illustrate that they are more sturdy than you might think. But you already have a Microdrive so you know what they are about. I think if I were to do it all over again I'd probably buy several high speed 1GB CF cards vs a Microdrive just for the file write speeds alone. Hope that helps!

When I transfer files from my camera with a Sandisk Extreme card to my sister's iBook running Panther using the USB cable, it takes forever. Much faster on both my laptop and desktop machines running Mandrake Linux. Even the USB 2 card reader isn't very fast on her iBook. I thought it was just something peculiar to her computer, but your experience leads me to believe that Apple's USB drivers aren't well optimized. From what I gather, the speed on Windows is about the same as Linux. I guess Apple focuses more on firewire.

To be fair, when I download files to my computers, I'm always importing directly into iPhoto. It would make sense that there's some overhead with iPhoto that makes the transfer slower since I'm both downloading the files AND importing into an application at the same time. There could be some write verification or other file maintenance going on. I suspect that a straight file copy from the camera to the computer would be faster, but I'm not inclined to test it. The point is simply that Firewire is MUCH faster than USB.

Be careful when importing via iPhoto as it will strip certain parts of Exif information out. I was chatting with a few friends and we all use Canon cameras of varying types but all produce Exif info. I was comparing notes with one friend and we saw different data either in Photoshop 7 or File Viewer. Then we realized that the person who sent us the photos had imported via iPhoto. So be careful. I'd rather use the desktop and just copy the files to the computer than iPhoto just for that one reason.
07/26/2004 02:48:41 PM · #21
That's correct. If Iphoto alters the EXIF, such a file would not be acceptable as an original.

The best way to retain your originals is a straight copy from the card through your OS.

I'll have to investigate this further. I've had problems retaining EXIF info in iPhoto in the past, but it was always as a result of saving the original in Photoshop, thereby overwriting the file in iPhoto (ID 10 T error). As far as I've been able to determine, unless you overwrite iPhoto's original, that is the same, unaltered file that came off the CF card. Nearly all of my pictures are stored in iPhoto, and I've had many verified by the SC without incident (aside from the aforementioned stupidity).

As a long-time iPhoto user, I can only confirm this. I have never lost any EXIF data or had any related incidents
