I was thinking about the D800 and imagined large 36 megapixels per shot. The D800 has memory for CF and SD cards, but I see those cards getting filled up faster than ever before with 36 megapixel raw files. I know lots of people carry things like extra batteries and extra CF/SD cards, but I know personally I never switch memory cards because I never have to using 16gb or 32gb cards on 10mp and 12mp cameras.
Then this got me thinking about battery life. With my Leica X1, I would carry TWO extra batteries in my pocket (seriously, a big annoyance) and just smiled when I thought of my D3 and its monster battery that would last days, if not weeks. I wondered there has to be a better solution to memory in these DSLRs. Then I thought the largest improvements in laptop/desktop speeds we have seen the past few years has been the harddrive speeds! Solid State Drives are really amazing:
Pros of SSD vs HD:
- They have no moving parts
- Use very little power compared to HDD
- Are blazing fast
Cons of SSD vs HD:
- NAND drives perform great but will continually degrade which I think has gotten better but not solved yet
- Expensive compared to HDD for price to gigabyte size
If you compare SSD to something like CF cards, here's how they stack up:
- Gigabyte Space: SSD (64gb, 120gb, 256gb) -- CF (16gb, 32gb, 64gb)
- Write Speed: SSD (100mbps to 250mbps) -- CF (30mbps to 60mbps)
The cons I figure would be SSD is large. 2.5" hard drives are the norm right now and are too large to jam into a pro body. However, smaller versions are on their way. Intel showcased this SSD drive that was 1/8 the size of the 2.5" drives.
So I wonder if we'll start seeing small SSD drives take over CF cards in the future? It could still retain the ability to swap and replace memory cards like we do with CF and SD cards, but will instead have all the speed/size advantages of SSD drives. I can imagine a 256gb mini SSD drive with 250x mbps write speed would be pretty awesome to pop into a DSLR. You could shoot the D800 for weeks
The fact we haven't seen CF cards really improve in speed or space capacity the past 3-4 years tells me they're on their way out. Thoughts?
