Long term reliability of P2

I’m not trying to crash the HVX P2 orgy and steal the pudding, I just wanted raise what I felt were some valid concerns over the long term reliability of solid state memory.

Okay,
I was recently discussing various memory solutions and video formats with a friend who’s close to some testing conducted here in Houston over the last 3 years on solid state and hard drives for storing large amounts of data in various conditions.

Basically, the testing revealed that solid state--flash memory with high data rates and storage capacities without a heat syncing and cooling solution is prone to “sector loss error”. Like burnt out pixels on your CCD or CMOS for your camera that have to be mapped out in post, after writing, unloading, reformatting, rewriting, unloading reformatting etc. large amounts of data, the semiconductor eventually loses segments of its storage capacity and will have a frame or series of frames for video that will be garbled or completely blank, and will have to be resolved in post.

Aside from there being no applicable cooling solution at the moment, we went on to discuss 0 power loss molecular solutions, such as Carbon-nano-chains, which is also being researched here in Houston as well, but that’s a little far off :)

Anyhow, this is something I felt was deserving of some attention.

Again, I’m not trying kill the love, I’m just raising concerns over the long term reliability of solid state memory.
I encourage anyone with information that may alleviate my concerns over P2’s long term reliability to please respond—nicely if possible :)

Thank you
 
I'm sure panasonic is doing extensive recording and reformating tests to make sure the longevity of the P2 hardware lasts a certain number of times. Of course they could never test wear and tear of physical handling of it.
 
Dood....every kind of Solid State Memory is prone to errors....EVENTUALLY. I've replaced RAM several times because a portion of it goes *whacky* and starts causing all kinds of errors.

I wouldn't think you wouldn't have too many errors even after a few years of use with a P2.

But I guess that is for Panasonic to decide with their extensive R & D.

Of course, but are you suggesting that in the event I discover I have an error prone card that I just go out and buy another? It'll be interesting to see what kind of warranty they have on these things.
In about 5 years, maybe it won't be such a big deal because the 4 and 8GB cards will be as cheap tape stock, but then there will also be cards that are more secure in the transferral of data, which means it comes at a cost, and the cost of being more secure will remain relatively high, so effectively the cost of the cards remains pretty much the same.
 
Panasonic is placing it reputation and future on the line with P2. You'll have to ask Jan for the particulars, but it would be pretty standard to do *extensive* testing on the cards to check the error and failure rates. They'd also likely test the physical properties of the cards including the number of cycles they can be plugged and unplugged. Environmental testing including pressure, temperature plus G-shock testing are also standard sorts of tests. I'm sure Jan would be happy to outline the testing when she has a free moment.
 
:Agreed with Barry.

No...of course you can't replace a P2 card like you would a stick of RAM (Well maybe in 5 years!!), but as Barry and others have stated....there will be *massive* amounts of R & D put into the P2. You just don't uproot yourself from tape and lay it all out on the line without being pretty darn sure of what you are doing. Panny knows this. I'm sure there will be a warranty. I'm sure everything will be *cool*!!

But then again, you could argue the same points with Hard Drives. Eventually, ALL...yes *ALL* hard drives WILL fail. Whether they develop a bad *sector* or you have a major *Head Crash* and one of the platters gets damaged.....or the heads just let go on their own.....HD's will have their issues too. They always have. However, hard drives are alot cheaper to replace than a shiny new P2 card.

I'm sure Panny will address this issue up front, because *literally*....the life of their company will be at stake when they eventually infiltrate all their major cams with P2. There will be little or NO room for *errors*.....PUN INTENDED!!
