Lucas123 writes "In the face of Seagate's announcement this week of a new hybrid drive, Dell subsidiary Alienware just upped the ante by doubling the capacity of its desktop solid-state disk drives to 64 GB. Dell has remained silent on the solid-state disk front since announcing a 32-GB solid-state option for its Latitude D420 and D629 ATG notebook computers earlier this year. Now, Alienware seems to be telling users to bypass hybrid drives altogether. 'Hybrid we consider to be a Band-Aid approach to solid state,' said Marc Diana, Alienware's product marketing manager 'Solid state pretty much puts hybrid in an obsolete class right now.'"

IT: Data Storage Predictions for 2008 81 comments
Lucas123 writes "IDC just released its predictions for 2008 with regards to data storage trends. Its research shows, among other things, a greater adoption of online backup and archiving services, the 'prevalent' use of full-disk encryption in the data center, and mainstream adoption of solid-state disk drives due to falling prices. From the story: 'There are very simple situations and application scenarios where solid-state disks will be worth the risk. It does promise some great potential benefit in terms of I/O ... [and] solid state will make a significant impact on reducing heat from spindle usage in server blade deployments and to boost functionality in mobile devices.' According to IDC, storage capacity is exploding at a rate of almost 60% per year."

Why does your computer have a relatively small amount of RAM and huge storage? It's the same economic question we've been facing since the introduction of computing. You need some fast, temporary storage and some slower permanent storage. And the reason has nothing to do with technological barriers -- it boils down to economics. Memory is expensive, hard drives are cheap. That's it. No matter what happens, nothing is going to change that equation anytime soon. SSDs will remain a niche technology for gamers with deep pockets and maybe a few other high-end uses like scientific computing. It will take at least a decade or more before this filters down to the point that the average PC is using SSDs.

Damn this is going to make crash recovery a nightmare. When my hard drive crashed I was able to read the data off by opening it up and using a magnifying glass, pen and paper. Using my notes and a typewriter I soon had my old drive data mirrored onto my new drive.
Is it possible to do this with a solid state drive?

Hybrid is a band-aid? (Score:5, Insightful)
Now there's a misleading quote if I ever heard one. Magnetic drives currently allow for storage of 250GB and up for a cost of $0.50/GB or less. In comparison, Flash Drives are are still measured in dollars per GB. The hybrid drive allows a bit of a tradeoff. A fast storage cache combined with massive space in exchange for a slight increase in price. Thus it's possible to have 1TB or more of storage, but with the performance characteristics of Flash memory under most circumstances.

And what do you get for that ridiculous amount of cash? According to Alienware's best PR spin:
"speed up operating system boot and application launch/runtime by up to 2 times."
"consume up to 50 percent less power than rotating HDDs."
Those specs aren't exactly thrilling, particularly since "up to" tends to mean you'll never get close to either spec.
Seems like a complete joke to me, which oddly fits in quite well with the rest of the Alienware line-up.

Re:Can we let the old "write limits" go now? (Score:5, Informative)
Strangely enough, modern flash is about 100k write cycles for high density SLC NAND and 10k writes for MLC NAND. Newer flash actually gets worse as the densities get better.
Even so, with proper wear leveling and sufficient redundancy you can achieve failure rates better than a spinning media. In fact, you can pick the numbers to achieve any arbitrary failure rate.
As for speed - you're correct, no single flash chip is 50MB/sec, but you can stack many of them in parallel and get that. That's a common way of doing it.
I think you're being overly harsh and pessimistic with your figures. There are some workloads you obviously shouldn't pair with a NAND flash, but quite frankly gaming isn't going to stress these things.

which is a whitepaper which shows a 64GB NAND device with a 100MB/s write speed can go for 20 years continuously, with error correction, before hitting the write limit. They didn't use the same numbers, but for a device with a likely lifetime of less than 5-6 years, they certainly seem to be up to practically any task.

These days (well, since YEARS ago now) we have this thing called Wear Leveling which means you can't wear out NAND flash by simply writing over the same portion over and over again. The writes get spread around other areas instead.

Windows is a frighteningly bloated beast. But I'm pretty much preaching to the choir here I suspect.
The way to deal with the swap file is a ramdisk. 3 gigs for Windows(assuming you're NOT stupid enough to be running Vista) and the remaining 1 gig windows doesn't usually access is the swap file. Problem solved. You just tricked Windows into using real ram instead of the hard drive.(as it should have been)
It nearly quadruples speed in XP, btw.

Most flash controllers remap the sectors on the fly to ensure that the memory is not worn down prematurely. So if you rewrite the same logical sector 5 times over, a chance exists that you'll get 5 different physical sectors.

- Flash used to have a limit of about 500,000 read/writes. That limit has since been surpassed. I gather it can exceed 1 million now, though Wikipedia still says the former.
- Although it wasn't addressed in the article (dammit), it has often been suggested that some on-disk monitoring and allocation mechanism will prevent areas from burning-out, or from being used if they do burn out. (This will be a particular issue for page/swap/scratch-files)
- Given that hard drives usually have a MTBF of something like 3-5 years, the technology only has to be good enough to meet that standard before it becomes as technically viable as HDDs.
- Given its other advantages over existing HDDs (even hybrids), I imagine that it will be considered viable - especially in laptops - long before it reaches that level of robustness.
Can I just say, it's about time they brought out a version that could compare with existing low-end laptop drives in terms of capacity. If you ask me, that's what was really holding back the big-spenders from buying into this tech.Parent

Pet peeve: MTBF is not life expectancy, it's the average time between failures if you replace the drives before they are expected to die. Common MTBF are currently anywhere between 50 and 150 years (mostly made up numbers), whereas life expectancy is in the 3-5 years range (at best).

Not quite. If you don't experience any failures, then you can't calculate the MTBF because there are no failures to calculate the mean time between. That does not imply infinite reliability, just that not enough data has been collected.
