It MIGHT work - if the listed specs are accurate. It only needs to be able to write at 5MB/s so support EX1/3 in HQ modes.

Does this Sandisk reader do the job? I don't see it mentioned among the posts (but there are a lot of them!): Sandisk SDAD-109R? I can't see the Kensington at B&H.

I just came across the Transcend Express/34 SSD units.

Does anyone think these even have a chance of working?

If that works and the door closes on the EX1 ... wow.

Is there somewhere ... please ...

a complete explanation about all these bits and bytes and MB and Mbit per second
and so forth??? Where can a read that a card matches the required specs or better said
is read and write speed in MB/s bites or Bytes, is the datarate in HQ 35 MBits or MBytes?

I am confused (and never was good at maths, I must admit).
Someone please enlighten me. Thanks.

all video rates are usually in bits (little b=little bit big B=big Byte).
1 Byte= 8 bits.
so 35Mbits/s= 4.375 MBytes/sec

Usually, capacity (size) of a device is expressed in Bytes.
so a sandisk card is 16GBytes running at 15Mbit/sec or 4.375MBytes/sec.
You still have to guess if the unit is described using 1000 or 1024 multiplier.....

anyway, even if you know all of this, it stay useless since experience shows that card rated at good values are still unable to function properly.

It is a bit like "lumens" or "watts" when applied to consumer electronics.
Marketing B.S is very creative at using science....

Peter,

You really couldn't find this information in this thread? It's been detailed two or three times in the past NINE HUNDRED POSTS! AAARRGGHHH!!

Seriously, though, this has become a cumbersome and even daunting thread for those stumbling across it to find out information. I suspect we'll need to answer many of of the same questions over and over.

I know this question has been posted before but I still have not seen the true
answer... ( have seen workarounds)

The question is " has anyone found a card holder or case that is specific to these cards "


Thanks

Giroud you can't have it both ways.
You say
35Mbits/s= 4.375 MB/sec
then you say
15Mbits/s= 4.375 MB/sec

Which is it?

Which is it?

Ronn I think this is a typo and should read 35 MBytes in both cases.
Nothing else makes sense to me.

Greg - hey my friend I didn't know you had an EX1. Good to know if I need a 2nd - and vice versa. My contact info is at kilby-dot-tv .

As for this transcend 32GB card - why don't you buy one and let us know? :)

That cards write speed is 8MB a second. Considering real performance is usually around 2/3rds of what's stated (the sandisk 15MB a sec are found to be what, 9?), that leaves no headroom whatsoever for HQ recording.

According to the specs, it can write at "up to" 8MB/s (and reading at 18MB/s) - I think the SDHC cards we're all using are writing around 6MB/s - so it sounds to me like it might work.

Good point Jon - guess we'll have to see.

Are the Transcend 32 Gb cards faster than the Lexar SSD Express 8 Gb?

Based on what we've discoverd through many tests, the bottleneck is NOT the SDHC or Kensignton expresscard, but how fast the EX camera communicates to these expresscard USB devices. Sony either did this intentionally or bad coding for USB transfer. My guess is they set a limitation intentionally. Even their own PHU-60K is limited on the expresscard USB interface.

Just a quick update on Kensington 7 in 1 card availability. Ordered a couple from Amazon.com on Fri 11/14 with Amazon's notation that cards are out of stock and they would notify of shipping date. Later that afternoon, received email that cards would be delivered between 11/19-11/21. Received confirmation of shipment with tracking number on Sat 11/15.

Also decided to try a couple of Transcend 16gb cards which, at $28, is less than half the price of the SanDisk (which has been working well for me). By all indications, Transcend should perform as well.

I tried them. They fit great, but they're too slow for HQ, and I think even SQ. They would record for a short time then error out. I returned them. If they did work they'd be a great deal. I measured the speed on my Macbook Pro with some benchmarking software and they were quite slow, so I believe this was the problem.

It's the class 6 8 and 16gb cards that work without issues, I am sure that the pioneering members of this forum will soon let us know when there are new products that work.

Does anybody else find it peculiar that whilst SDHC, Compact Flash, and a few other varities of solid state memory come in a variety of speed specs, all that's available in an ExpressCard form (excluding true SxS) is something that well underperforms even Sandisks Ultra II range? Especially as high data speeds were a big reason for ExpressCard superceding Cardbus?

It's possible to construct conspiracy theories, but I feel it's just that these cards pre-date the introduction of SxS, and are maybe seen by Transcend as a very minor line - most solid state users will just use the popular sizes, CF and SDHC.

In which case, it needs bringing to the attention of somebody senior in a company like Transcend that devices like the EX1/3 now represent a potentially large market for an ExpressCard memory of the performance of ExtremeIII, with a price tag to match.

Whilst SDHC is the answer for a huge number of people, I suspect that in the broadcast world it may just be seen as too small and flimsy, not to say easily lost. But bring out an Extreme III version of Express Card, and it is effectively "solid state tape". All the solid state advantages of P2/SxS, with the consumable pricing of tape or disc.

Everything in this thread PROVES that the high performance (and price!) of P2/SxS aren't necessary for recording broadcast quality video. But wouldn't it be nice to have that lower (but adequate) price/performance in a form factor native to the EX.........?

Just a note in thanks to those that have gone before.

The Kensington/Sandisk combo works in the Sony EX-30. We use the the EX-30 deck as a video assist for Red work. The Red outputs 720/50p over HD-SDI (25p time base for PAL production) and we have had zero problems in record and playback using the combination.

Our regional dealer based in Australia has had these on backorder for over a month. I called to chase up the order. The dealer said there is some negotiation going on with Sony and Kensington over the product which was delaying the shipping of the Kensington 7-1. I was the 3rd call he had received that morning on order status.

I placed an order through Amazon for 5 Kensington 7-1 adapters, just in case ;)

================
That doesn't sound good.

John

I'm not believing that. In fact, I'm willing to bet 99.99% of the people at Kensington never heard of a Sony EX1. Also, Kensington is not the only card that works. There's been reports some of the cheapies on ebay also work.

Steven, I would assume that Kensington is very much aware of the EX-1. Amazon is out of stock, B&H out of stock, 0 listings on ebay for 'Kensington 33407'.

I would think the dealer I dealt with is just feeling the effects of worldwide demand and supply rather than any conspiracy theories in play. And the 3 previous calls he had were from EX owners!

About three weeks ago I sent Kensington an email regarding designing an SDHC Expresscard media adaptor that would allow the Sony PMW-EX1 memory door to close. Well, after several emails back and forth it certainly was clear to me they have NO idea about the EX1.
I certainly did not expect them to know about a particular Sony video camera.

Also, I'm not surprised the stock kensingtons in online stores were bought up. Heck, two months ago I bought four myself from Amazon and at that time they only showed 22 in stock. We've all been buying these. Also, someone mentioned even before this became a hot subject that they heard these cards are being discontinued. This particluar expresscard has been out since 2006. It's not a new product.

Also, someone mentioned even before this became a hot subject that they heard these cards are being discontinued.

Glad I stocked up! :) The sales chart on the product must have an interesting spike!

BTW, Kensington web site has the 7-in-1 card "in stock" right now to order.

I contacted our distributor here in Australia back in Sept when all this was starting up, and they told me that the 33047 was now obsolete, and would not be produced again. They told me that it was originally designed to work in a MacBook Pro but it wouldn't allow the laptop to go into sleep mode, and was quietly removed from the market. They told me uncategorically that it would not be made again.

But then you see it in stock.

Who knows?

I have heard a whisper that there is an upcoming expresscard that will allow the SDHC card to be enclosed completely inside it, ie will allow the EX1 door to close, so the Kensington card may become redundant.

Could you give a hint which other supplier/manufacturer you are talking about?
Amazon.de have sent me one Kensington card but are already out of stock again :-(

In fact, I'm willing to bet 99.99% of the people at Kensington never heard of a Sony EX1.
Initially, maybe, but I suspect that for the last couple of years sales of these adaptors have been pretty low and static. Then a big jump in the last couple of months. I can't believe that hasn't led the Kensington sales people at least to wonder "what the.....?"

As for Kensington/Sony talks, well, who knows? If true, there's two ways of looking at it: Sony want to squash it, or are looking at making it official!? Maybe a Sony badged version, certified for EX use, and designed to allow the door to close...... and maybe costing 50-100% more?

Hi Peter,

I'm not allowed to say much more than that at the moment. I just wanted to let everyone know that not being able to source a Kensington cards is not the end of the world.

On another matter, has anyone had any success in sourcing the 32G Sandisk Ultra II?

Hi Ross,
Nice japanese answer ;-) Hope we will have an opportunity to discuss that over a stubby of whichever brand you prefer in the not so distant future :-) P.

Hi Peter,

A stubby sounds great, and as any Aussie knows there's only two types of beer.... Aussie beer and everything else. So I guess I'm buying!

Just got some imported cards that I think Ross also got (Phillipines post back a bit) and they work fine although the EX3's door doesn't close but easily fixed with a velcroe tab! Thanks Ross!

I can get 50 FPS overcranked too and both formatted straight away using Sandisk 16gb 11's...excellent!

Evan

Aussie beer and everything else.

No doubt about that... My shout's next... *Relax mode on*

just picked up a Kensington 7 in 1 at Yodabashi Camera in Akihabara. Theyre 5000yen ($50) and they had plenty in stock so let me know if you need one.

kubalsky

Just received an additional 2 Kensington 7 in 1 cards today (11/18) from Amazon.

Was in touch with SanDisk press relations to get some info on 32gb SDHC availability. All he said was that "we don't have any here." Was really looking forward to testing them both for the boards and for an article as well as to using 32gb cards for a shoot in early Jan. Hopefully they can deliver by then.

picked up 2 kensingtons ($46) and 2 16 ultra 11 cards ($90)- had them delivered - came in a day. Good stuff will test them out today.

I opened up my sandisk, to discover it's pretty much empty.

Awesome Jon...your the man!
Can't wait to start chopping!

It's amazing how small these cards "really" are!

Cheers, Evan

odd, I opened an A-data card and it was full all the way to the top.. only 4 gig too.

Why does the door have to close again?

Seems easier to change cards during a shoot if the door stays open. Or am I failing to see the importance of this?

John

Jon,

You are both brave and a genius!

Dan

Why does the door have to close again? A lot of users are worried about the door snapping off/getting in the way/letting dust in/sex appeal.

I did a real ghetto job, you should be able to dremel/sand just enough off the card to let the door close, but still be able to pull it easily out of the kensington.


all up to you!

Just upgraded my firmware and picked up a kensington adapter ($34.43 at buy.com) and 16gb sandisk ultra ii sdhc (~$65 at adorama). overall very impressed at how easy it was. im surprised the setup doesnt support 60fps overcranking given the card is rated at 15MBps by sandisk and my computer benchmarks it at 17MBps read and write. maybe i should do a benchmark reading the card through my ex1 to my computer over usb, i bet the camera isnt getting all it can out of the card. oh well. i am debating maybe buying a whole bunch of these cards and a cf-sdhc adapter so i can use the same sdhc media for the ex1 and the 5dmk2 (when it actually ships, i preordered 2 months ago). might be nice to have faster cf media, though, since it could double the speed of offloading footage, but at 3x the price.

Noah, it's buried in these posts. But after a LOT of testing we're fairly certain the datarate limitation for USB over the EX expresscard slot is a Sony issue. Or, Sony intentionally limited this datarate, which is what I believe.

Hi Noah, I don't think it would work with the 5Dmk2 as the door needs to be shut before the camera accesses the card...unless you can bodge up the door's sensor! Plus it would stick out a mile on the 5D!

Evan

I think Noah means putting the SDHC card in another adapter, this time CF-SDHC. Noah, do you know if CF-SDHC are actually available? I have CF to SD, but it does not work with SDHC cards.

Dan

yeah sorry maybe i wasnt clear, i was talking about putting a cf-sdhc adapter in the 5d and putting only the sdhc in it. expresscard adapter for ex1 and cf adapter for 5dmk2, only the sdhc card moves around.
