SanDisk life expectancy

I was wondering how many times a person can rewrite to the SanDisk. From my understanding the SanDisk is just a version of flash memory that is arranged and operates like a hard disk. From what I have heard, flash memory can only be rewritten a limited number of times reliably. Is this true? I was thinking of running an IO without a hard drive, just using DOS 6.22 in the SanDisk. Some files need to be rewritten on a frequent basis and I was wondering if this was a thing to do or not.

I wouldn't worry about it.....After all, the I-Opener was designed to work 100% off the san-disk. Should the disk ever fail (doubtful), you could always buy a cheap small-sized hard drive.....

50,000 to 100,000 FULL WRITES to the sandisk. Oh the more you use a sandisk like a hard drive, the thing gets REAL hot after a while when writing ONLY. cools quickly but writing creates a lot of heat. I'v tried in the past and couldnt write more then 5 complease writes to the sandisk in winblows copying a 16meg file over in a row befor it would fail. Then i waited a few minets and it worked just fine again.

As for the design of the sandisk. It's created to be a READ ONLY device. Meaning your supose to write your software to it wonce and just boot/read from the drive not writing any thing. And only writing something if you need to update your software. Trust me you can rack up a LOT of writes to the drive in no time. and SMALL writes multi times in the same spot can render that spot over time to not work SWELL any more.

I'v got a FRIEND who's a phototographer and he uses both a digital cam and reg film cams but he goes thew about 1-2 32meg flash disk things what ever ver his cam. takes every year or two. believe it or not the amount of pictures he takes both in a studio and on site be it a wedding or WHAT EVER render the flash card DAU after a while. He said he does about 75,000+ pictures a year. That figure is for DIGI cam only. :) its a wonder why he owns 3 cars a boat, and 2 houses down south some where ;). good thing i can use them for a vacation if i ask him ;).

I know a while ago for fun he was making a still image movie using the digi cam. got to some point and lost like 40 pictures because he had?? i forget how many pictures pictures realy but one flash card just didnt work all of a sudden. after snaping the last image he brought the card to his computer to look at them and got the last 2 and the 3rd showed up like half way and the rest just wouldnt read. The disk was toast.

I wonder if this has any simarity to the static ram chips that were used in VCRs to store channel data. As I recall they required a refresh rate of about ten years. I wonder how long the sandisk will hold onto it's **** without a power up.
