NitroAV FireWire 800/1394b Express Card (34)

After some foot dragging by FireWire direct, today I finally received the NitroAV FireWire 800/1394b Express Card ordered almost a month ago.

First Impressions: Unimpressive at best.

According to the FireWire direct rep, it is supposed to work using the Mac OS built in drivers and require no additional driver....

Upon first insertion, my MacBook Pro promptly went into a kernel panic.

NOT a good introductory performance!

Upon restart, I did get the thing to work, "sort of".

First, it requires AC power even with a 2.5" external drive meant for bus power. Bummer, but so be it. However, less acceptable: it is VERY fussy about sequence, reminding me of evil SCSI voodoo rituals from the past century. Seems it only likes to work once- if I remove the card, it requires a reboot to recognize anything attached to it subsequently.

Functionality is intermittent. Sometimes I can mount and unmount a drive several times in a row, sometimes just once before it fails to recognize the drive and requires another reboot. One drive it took a long time to recognize but eventually it did- only to freeze up rock solid soon thereafter requiring an uncomfortable long push on the power button to shut down- nothing else worked. That drive was a known to be working Lacie, the first a known to be working WiebeTech and both are totally reliable on my G5 and previously completely reliable on the MacBook Pro using the integrated FireWire 400 port.

Unscientific results so far show a modest speed increase transferring a few large files, nothing like double the FireWire 800 speed hoped for. In any case if it ain't reliable it ain't gettin' used. Hoping for a driver solution in 10.4.7? (Wishful thinking)

No one likes a fussy device, much less one doomed to corrupting directories with that kind of behavior. I'm disappointed with Apple for omitting the FireWire 800 port on the 15 inch model and leaving us with this cheesy "solution".

I am not a big fan of dongles, or things like Express cards which are just asking for trouble by introducing intermediary third party connectivity issues exactly like these...

Oh yeh, and the little metal door on the Express Card slot tends to hang open and not snap closed- just to add insult to the whole process.

Did you UPG frpm a PowerPC model using the migration assistant ?

Meticulous clean fresh installation of all software from original installation disks. No previuos history of kernel panics. I'm confident that the problem originates with the card, or hardware/software related to the card. Ain't pluggin' it back in there until I receive more feedback and a resolution.

A word of caution to others with this card- back up your data before testing it! I have not lost any data but the type of damage it's "activities" might cause include data corruption.

bigwheel,

Any news on 10.4.7?

I've had a Nitro on order for my MBP for a month now, and they just charged my credit card (so it must be shipping ASAP).

I'm curious what to expect. as it seems that everyone's experiences have been quite mixed. Thought of canceling, but do we have any other options? So looks like another $100 experiment on my end ...

Well, after two days of use I have a bit of data regarding the NitroAV (and Apple's implementation of ExpressCard/34).

First some general observations: like bigwheel, there are a few too many rough edges to be fully pleased. After inserting the card, a menu bar icon appears next to the Airport icon. On mouse over, the drop down shows "Unknown Vendor" and "Firewire Controller" are greyed out, while the 3rd "Power off Card" is selectable but does NOT power down the card. Looks like I have to shut down the MBP, then eject the Nitro card.

I also can confirm intermittent unmounting and remounting. My latest experiment is to leave the drive mounted and then have it wake up after sleep. So far it's worked once, but will post if it continues to find my FW 800 drive over time.

One major design flaw of the ExpressCard implementation - to engage the card you push in until it clicks, while to disengage the card you merely push in a second time. But how are you supposed to ATTACH FW800 cables?? I find I have to try to hold the ExpressCard firmly so it doesn't go in while fumbling with the FW800 connector. WAY too fussy...

OK, here's some actual test data, involving transfers of 1,000 MB of files (147 Canon RAW files, approx 7 MB each).

I used three hard drives for various transfers -
1. Internal stock 100 GB - 5400 rpm (TOSHIBA MK1032GSX)
2. FW 800 / 400 500 GB - 7200 rpm (Seagate 3500841A in OWC Mercury Elite case)
3. FW 800 / 400 250 GB - La Cie 7200 rpm drive

---------
All test are transfer of 1 GB of files from HD to HD-

Test 1: Internal to FW 400 - 68 seconds

Test 2: Internal to FW 800 - 65 seconds

Test 3: MBP built in FW 400 daisy-chained - 54 seconds

Test 4: Nitro FW 800 daisy chained - 43 seconds

Test 5: Nitro FW 800 port A to Nitro FW 800 port B - 43 seconds

Test 6: MBP built in FW 400 to Nitro FW 800 - 35 seconds

So it looks like there is some speed increase, but I was surprised that mixing the FW 400 and FW 800 ports gave the fastest transfer speeds! The Nitro card is dependent on Apple's implementation of buses, and this seems to be the winning combo. Not that intuitive that shifting one of the FW 800 devices down to FW 400 will speed things up, but that's what my simple test seemed to imply.

I didn't test read times only, but it would seem that these should speed up (and hopefully speed up my primary application of Aperture).

A follow up to my previous post.

I have now had my 500 GB HD (7200 rpm Seagate 3500841A in OWC Mercury Elite case) hooked up to the NitroAV card for 3 days with no problems.

I've put the MBP to sleep numerous times and it wakes up fine and mounts without problems. So it is proving to be an acceptable solution to the missing FW 800 port on the 15" MBP. Hopefully when the new MBP enclosures come out this fall (per the rumor boards) Apple will provide a built in solution for FW or eSATA.

The one ongoing weakness is the inability to eject the card. But maybe this could be able to be addressed in an OS update ...

This card worked with the early build MacBook Pro but does not seem to work with subsequent builds. It will not stay seated properly and pops out. FireWire Direct has been less than easy to work with in terms of getting a refund. Buyers should beware until this problem is addressed. Because it is so early in the implementation of this technology, everyone I talked to at AppleCare and and Nitro seem to not know what's going on with this incompatibility.

Dear Parties (Christopher Boffoli & BigWheels)
The issues with the NitroAV Express Card is not uncommon when new technologies are introduced - specifically the Express Card slot on the MacBookPro. If anyone remembers FireWire original implementation it was anything but easy and initially supported speeds of only ~6Mb/sec.

Since MacOSX 10.4.7, all software issues seem like they are resolved and supported but there are still growing pains expected and future operating tweaks to come - like original FireWire implementation the Express Card FireWire800 device should see very nice speed increases from it's original performance as the drivers/OS revisions are tweaked.

The card has been verified and tested in not only MacBookPro Express slots but also Windows based 54mm Express Card slots.

We have not be able to explain why some vendor express slots are different from one machine to the other and it is not common but we have seen it. We are working hard to resolve any issue that can be resolved by us. All customers are offered 30 day money back warranty and for any reason they are not happy can return them within the 30 days.

got the second one in July....just had an opportunity to try it tonight and have the same problem.. it shows up in the top bar of the screen but it doesn't work with fw 800 cables. Tried it both installed when booting up and tried it inserting it after the machine boots. No go, either way. This is not only the second card but also a different notebook. Guess Nitro (or their distributor) isn't ready with these yet. Since it's beyond the 30 days, I won't be able to get a refund. But it's my own fault for not trying it in the computer immediately.
