Not sure of the price/density coefficient multiplier for flash versus hard drives, but if it's near unity then these should be set to disrupt the magnetic drive

Not sure of the price/density coefficient multiplier for flash versus hard drives, but if it's near unity then these should be set to disrupt the magnetic drive market in 4-5 years.

This 1 TB SSD is listed on Amazon for $3919.99. 1 TB HDDs are listed on Amazon starting at $84.99. SSDs are already disrupting the high-performance storage market, but I think it will be more than 5 years before they disrupt the bulk storage market.

  My parents, representative, I believe, of the average computer users, have an 80 Gb hard drive that is at less than 15 % used capacity. The point at which, say, twice that level of storage drops to less than $100 in SSD format makes a strong economic case for widespread consumer adoption. We see the beginning of this in netbooks.

    I only use about 40GB on my laptop. I'd buy a 60GB disk for $100, but not a 120GB for $300. They should concentrate on getting the price down rather than the capacity up. They're too expensive.

      Maybe there making a play on high end storage requirements knowing they can't compete on price/ speed at the smaller end of the market.

        I'm guessing that's the case. We specced these in feb to replace the disks in one of our clusters; not quite economical yet but getting there. When we deploy the next storage cluster in June I expect it will be with SSDs.

      It's getting pretty close, with various 32 gigs under $100 and 40gigs and 60gigs in the $100-$200 range. $130 for a 40gig Intel for example: http://www.newegg.com/Product/Product.aspx?Item=N82E16820167025 http://www.newegg.com/Product/Product.aspx?Item=N82E16820167...

        That's easily within reach. I remember there being issues with read/writes. You could only write so many times or read so many times. Is this still true? How long will an SSD last?

        Theoretical reliability and lifespan is much higher than that of mechanical drives. There have been bad "batches" of SSD drives from one or two companies, but there are from mechanical drive companies too. "Thus Intel will guarantee that you can write 100GB of data to one of its MLC SSDs every day, for the next five years, and your data will remain intact." http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3403&p=4 http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=34... People should have backups anyway, so I guess if the companies are standing behind these drives and all the users so far are pleased it's not really an issue, though it doesn't beat the mech drives really (although in mobile applications shock resistance is higher) but there seems to be no cons. It's just price, size and speed to decide on them now. Still, given the prices, for home applications I imagine people just want a boot drive and storage on a larger mech. On the server side there are probably quite a few databases that could benefit from 1TB with good random access and throughput.

        If you believe this - http://www.storagesearch.com/ssdmyths-endurance.html http://www.storagesearch.com/ssdmyths-endurance.html - a 64G drive might last 51 years of 24-hour, 365-day continuous writing at 80M/sec. But that assumes SLC, with MLC it looks shorter - http://www.storagesearch.com/ssd-slc-mlc-notes.html http://www.storagesearch.com/ssd-slc-mlc-notes.html - 6 months at the same rate. Personally, outside of data capture or similar applications with sustained turnover of large amounts of data, I think it's a non-issue in practice; and for those applications, the SLC drives are available at a higher price.
