Samsung Announces Solid State Laptop 114
An anonymous reader writes "Samsung has announced they'll be manufacturing solid-state laptops, with an eye for a June release in Korea. Everything you wanted from a laptop: faster boot times, quicker storage access, less noise, longer battery life. Laptop Logic has the story." From the article: "Now to the features of this laptop: Celeron M 1.2GHz, 12.1-inch screen, 512MB DDR2, Wireless LAN 802.11b/g, Digital Multimedia Broadcasting TV, and measuring 2.5 pounds. Price? $3,700 and only available in Korea in June."

If you don't move your browser cache off the drive and onto a virtual RAM drive, you will easily rack up millions of writes to the disk.
Now I know that solid state media scatters the writes around so as not to stress any particular sectors, but if you don't actively seek to reduce disk writes, it'll only take a few particular programs to really kill the lifespan.
The biggest benefit of solid state drives, is that they don't die, the writeable area just gets smaller.

Why does this myth refuse to die? These do "wear leveling" which moves the writes around the flash and means that you would need to write the whole drive one million times.
Let's do some math. One million writes of 32 GB equals 32,000,000 GB, or 32 PB.
Suppose you average 10 MB/s of writes the whole time your laptop is in use (good luck pulling that off). You would have 3.2 billion seconds of use, or 101 years of continued use.
Let's see a hard drive take that kind of pounding.
Re:Seek Time & Reduced Heat (Score:5, Informative)
There are two major flaws in such a mechanism. The first flaw is that it assumes that you can spread the load evenly among these spares. This varies from manufacturer to manufacturer. We will assume that the flash is made by someone whose algorithm is good. The second flaw is that, AFAIK, generally speaking, existing blocks are not remapped unless they are actually being written. The reason for this is that flash writes are relatively slow. To illustrate why this is a problem, it is necessary to give a fairly concrete example.
Assume that you have a flash device that is full (so that every logical block is mapped to a physical block). Assume that the vendor left an extra 25% overhead for wear leveling. If you rewrite random portions of the disk, there will be significant improvement in longevity, as each block is only rewritten 4/5ths as often. However, if you rewrite the same single block, you only have to wear out the 25% overhead plus one block. Assuming a 32GB disk, that's one million writes times 8GB + 1 block. (I won't speculate on the block size.)
But it's worse than that. You probably don't have a single 32GB flash part. It's probably a bunch of flash parts that are, at most, a gig or two, and in all likelihood, smaller. If each part is only 512MB, you can create a catastrophic failure of that part (effectively preventing any further writes to the part) with only one million writes times 128MB (a fourth of 512MB) + one block. Thus, even if you randomly use all the blocks on a single flash part and ignore all the others (which is typical usage for the first part of the disk, assuming the consecutive flash parts are mapped linearly), that takes the time down from 101 years to less than 2 years. If you do the "repeatedly write one block" technique, that reduces it from a couple of years to under 5 months.
Now all of these problems are, to some extent, solvable, but they would require a cross-chip wear leveling mechanism, coupled with OS intervention (or a relatively smart on-disk controller) to periodically remap random blocks without modification. I'd be surprised if either of these was being done.
In theory, wear leveling makes flash a reasonable alternative to a hard drive. In practice, flash needs to be at least an order of magnitude (and preferably two orders) more reliable before I would ever trust it with anything more than photos in a digital camera... and even for photos in a digital camera, I carefully limit the number of times I will reuse a flash card to ensure that I never run into these sorts of problems.

After doing more thorough researching, I found expensive 32GB SSDs but also 16GB SSDs at around $600 here [etech4sale.com] & here [dvnation.com]. I know that size is not always directly related to price but I guess the release of this laptop with 32GB means they've found cheaper ways to produce the 32GB versions.
The $3k price tag is probably pretty reasonable considering that two drives equating to the same size would run around $1,200. Heck, after thinking about the number of writes to the disk they're good for, it might benefit you to have your OS and apps on a drive apart from your userspace drive (a la Unix security layout).
Again, I apologize for not researching my link in the original post and for wasting your time. I only hope the discussion isn't waylayed by people pointing out my ignorance.

Probably not too hard. You'd need to develop a disk controller that takes an address and translates it to the correct bank of flash cards. Otherwise, you should be able to build the board with off-the-shelf parts.
The biggest issue is expense. Flash retails at about $20-$30 per GB. Which means that a DIY jobbie would cost about $640 - $960 for a 32GB model. Ouch.
