Hardware, Embedded Systems Samsung will early next month ship the first notebook PC and the first ultra-mobile PC fitted with 32GB of solid-state NAND Flash storage instead of a regular hard disk drive, the company announced today. The two machines - respectively, a version of Samsung's Q30 12.1in notebook and its Q1 UMPC - are both fitted with the 32GB SSD (Solid-state Disk) the company unveiled in March this year. Both PCs will go on sale in South Korea for KRW3.5m ($3700) and KRW2.3m ($2430), respectively.

I know of the RAM (DRAM) based drives and thoroughly dislike the idea of them being so unreliable (because of RAM being volatile). I think a design that I proposed a in my previous post would be a perfect medium. It'd boast extremely high speeds: I think about 400 Mbps would be easily possible with RAID 0 setup of 20 SD cards. With a huge cache of say 2 GB (this would be RAM based) we'd bring down the reliability factor, but only slightly. In the worst case scenario all 2 gigs would be filled. 400 Mbps is 50 MBps. At this rate it would take roughly 40 seconds to dump the whole cache onto the non-volatile flash storage. A tiny Lithium Ion battery could be implemented within the drive to ensure that this happens. This drive with the current prices could cost around $600-$800 but with the outlined advantages it would have a pretty good value/cost ratio. Most of all you'd need nothing more than SATA/PATA 133. No Vista on top of this, no extra drivers, since the drive itself could do the whole RAID 0/RAM cache thing. Oh and it could throw a S.M.A.R.T. warning if one of the SD cards is dying. Then you just backup the data off of it and replace JUST THAT CARD for a fraction of the cost of the whole drive. Make the damn thing upgradable (no upper limit on the size of the SD cards or the amount of RAM) and you've got yourself a wonder.
