They claim they use special algorithms as to how they write data to the SSDs ... that's their proprietary stuff and all that crap.
It's just SATA connection, so not much they can do.
The only thing I could think of is that they're buffering writes in such a way that they're trying to always write blocks of 512 KB or something like that, basically an exact multiple of the size of a block on a SSD.
Basically, you can write pages of 512 bytes or 4096 bytes at a time (or some other value) on a SSD, but you have multiple such pages arranged in a block. You can't erase a single page, in order to overwrite data in a page you must erase a full block, so if a block must be erased, the SSD has to read the pages with useful content, write those pages in other random blocks all over the SSD to minimize wear on individual blocks, then erase the block. This process adds latency so it could slow down transfers in theory.
If they code their stuff to always write block size worth of bytes, they could more or less guarantee each time a write is done, a full block erase happens and the block is filled with new data.
However, this would require also modifying the firmware of a SSD, because right now even if a SSD gets a block worth of data in its write cache, it will spread the writes to random pages all over the drive, across all the channels (to increase write speed)
It would simplify the firmware of a SSD drive by a lot, to just always erase blocks and write new data in, as the controller no longer has to track pages all over the place, but the camera would have to keep track of erases better and eventually refuse to write on a SSD that has too high of an erase counter.
For example they have those 120 GB mags which have the Kingston 120 GB SSD with TLC memory that cost 20$ ... those basically have around 80-100 TB worth of lifetime writes.... basically fill the ssd 1000 times and you're done.
Considering the RED camera fills could fill 120 GB in around 5-10 minutes of recording... someone could easily kill such a SSD in less than a year.
