Quoting george parker <georgeparker20@xxxxxxxxxxxxxx>:
I think some people have missed the point here. SSD's may be the next big thing but they are only a replacement for a spinning hard drive, using current technology. The storage medium has size limitations. The reliability may be better eventually due to lack of moving parts but the size per Gb probably won't be and speed won't be (I didn't particularly mention speed in my original drone) and power consumption is a problem.
You say that though look at the capacities of Flash and how they've come along over the past few years. For instance, when I bought my first digital camera back in 2002 it came with something like an 8MB Smart Media card. I then upgraded to a 'whopping' (at the time) 32MB Smart Media card. Now these cards were big in physical size, but still smaller than a CD/Floppy.
Now 8 years on, I have a few 4GB cards the size of my thumb nail, and I know that MicroSD capacities are reaching 32GB too (albeit not overly cheaply, but still probably only about twice that of what I paid for a 32MB card back in 2002). So in 8 years the capacity is 1000 times larger and the physical size is probably about a quarter of the size of the original Smart Media card.
So it's pretty certain that SSD prices will go the same way, the capacities will get larger and prices will come down as techniques and technology improve. I believe if you can afford it there are already 1 and 2TB SSD's available but they are very very expensive, but like everything, the prices will come down. Not to mention there have been SSD's demonstrated that saturate the 3Gb/sec speed of SATA 2 and with SSD's generally being smaller, I dare say manufacturers will start doing tricks like internal RAID arrays (maybe putting a couple of SSD's together in a drive enclosure with some box of tricks to speed things up further.
I certainly don't think hard drives are going to match that, it's already been demonstrated that the new SATA 3 (6Gb/sec) drives from the likes of Seagate are quick but not quick enough to even saturate SATA 2 (3Gb/sec) interfaces.
My point (I think) was that we need to refine the horse that we have while we wait for the motor car to come along.
Ahh, you mean a sleeker faster horse with more legs and go faster stripes? Rob -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
