Flash Memory HDD for Notebooks Launched

ukhackster writes "Traditional magnetic hard drive platters could be on the way out, thanks to SanDisk's launch today of a hard drive based on flash memory chips. The device can store 32GB of data and is meant for notebooks . SanDisk claims that using flash chips means faster access and better reliability, so less danger of a serious system crash wiping out all your valuable data if you drop your laptop. The downside, though, is price. At an extra $600 dollars, are price-conscious consumers going to be interested?"

    Hrmmmm..... just in time for Macworld? Oh please, oh please, oh please.....

    I've written about this before in a number of places, but most recently here on my last trip to Argentina, but I am hoping that we will see a revised 12in Powerbook nee MacBook Pro (or smaller) in the next Macworld because I really do miss the smaller form factor. It would be tremendously useful for travelers and photographers as well as giving us better battery life.

    I am currently using a 15in Powerbook that I traded up from when the 12in Powerbook was cancelled, but a smaller footprint would help tremendously with travel. With the 15in Powerbook/Macbook Pro, I love the illuminated keyboard and the performance, but would be willing to pay a premium to carry a smaller laptop, subnotebook or tablet running OS X. It does not even have to have an optical drive as I rip movies I purchase or rent to the hard drive for long airline flights and in fact, if we could get flash drives down a bit in price (or get a sweet deal on bulk purchases for the manufacturer), it would be possible to even get rid of the hard drive provided we could still pack 30-40 GBs of storage space in the device. Battery life would be improved and if you combine it with a 10in diagonal new technology LED display (or OLED), we may even be able to get away with seven or eight hours of honest full on battery life. So Steve, come on dude. We've talked about this before several times. The technology currently exists or is damn close and I am sure there is a market for such a device, so please, please, please.

However, costs are decreasing to a point where we can now start putting these drives in Toughbooks (to make 'em even tougher), or portable devices that do tend to get bumped and thrown around a fair bit more. Just witness my last passage through customs here in the US where a "Homeland Security" officer inverted my laptop bag, dumping out the contents onto a desk from over a foot high. Laptop, point and shoot camera, cell phone and a portable hard drive loaded with photos all came crashing down. If there were flash discs instead of hard drives, I would have been perhaps less pissed off.

      The other category where flash drives are absolutely critical is for lots of remotely control data gathering devices. One of my friends who has been working on remotely piloted vehicles has been clamoring for just this sort of technology as it is much more rugged than hard drives for their applications (hard landings).

      The power distribution in a modern notebook is EXTREMELY dependent on usage and the special model you look at.

      Averaged, the biggest power-draw of a modern notebook is the display, followed by the cpu. (this may of course vary if the notebook has a very small display. With equal brightness, power-draw of course increases with display size, until it dominates everything else with those 17" 200cm/m^2 display). After that is chipset and GPU (of course depending on with model you use).

      2.5" HDs are actually not very power-hungry. Typical power-draw figures are 5W during spinup, and about 2W while in use (dropping to 0.5W or so during spindown).

      The FLASH drive mentioned draws about 0.6W in use, so in average you might gain 1.5W thats about 3-5% of the average power-draw of a modern notebook, and should give you about 10-15 minutes or so more.

      Modern NAND flash is in fact not much more of a random access storage device than a hard drive. This is different from NOR flash, which is typically directly addressable like RAM (and much more expensive than NAND flash). These devices can only be accessed as block devices at the chip level. You certainly can't write to just one address, you need to erase the block and then serially feed in all the bytes to it. To read, you can address individual blocks and read their entire content. Further complicating it is that these high density multi-level flash chips are much more error-prone and require error correcting data to be stored. This precludes them being used as true random access devices.
