2008, The Year of Solid State Storage 197
An anonymous reader writes "At CES, SSD drives were a plenty on the show floor. "Some companies said we could see 250GB SSD units by the end of this year, while others predicted it could take up to a couple of years for them to become mainstream. None of the companies promised mainstream adoption, but they promised a bright future and we are inclined to believe them. High capacity drives are going to be expensive due to their very nature of early technology and gradual adoption rate."
So we are back to RAM drives! (Score:4, Interesting)
I used a RAM drive on my Amgia way back when. Yes I know that they are how using flash but it does seem very familiar.
I wonder when we might see a hybrid flash-ram drive? A big bunch of ram for high speed and flash for permanent storage. Just use a super cap for a power backup and have it copy the ram to flash on power down. A little bit pricey but if you need the speed you need the speed.

Boot camp + solid state = me finally replacing the old powerbook!!

In the enterprise sector... forget about it... Even SATA drives are becoming ideal for storage solutions, and a simple raid-5 will max out the cap of a raid controller's bus.
So in other words... I don't see it.

Once that happens, I imagine that magnetic drives' usage will tail off sharply, and disappear within a couple of years, because nobody (or at least nobody worth speaking of) wants to use magnetic over solid state anyway. In fact, it might start happening even whilst SSDs have a small price premium.
God knows, I'd be happy to pay a 20% premium to never have to use magnetic hard drives again.

Hopefully computers will be completely free from moving parts in 10 years or so. Now that would make it interesting for laptop owners.
SSD as a boot drive (Score:5, Interesting)
Not only is the flash drive completely silent, it is reasonably fast. Reads always benchmark at 40MB a second and writes benchmark at 34MB a second.
I've been a bit worried about the flash wearing out after repeated writes, but so far so good. Since my mythtv mysql installation is stored on it, as well as the normal system log files, I'm sure it sees quite a lot of action.
But to my point...
One common problem with systems such as mythtv that are under heavy IO stress is that during these moments of stress (lots of recordings going on at once) the whole operating system grinds to a halt or at least becomes sluggish waiting on some needed IO.
It was very common on my old mythtv setup where I used the extra space on the OS hard drives as extra storage space for mythtv recordings. I'm not experiencing any of that sluggishness with the new setup.
This has got me thinking that for my future desktop system, maybe instead of getting a raptor for the OS drive, and a large, slower hard drive for the rest of my stuff in order to minimize IO bottlenecks, I should swap out the raptor for a 16GB SSD for the OS drive. I'd end up with something that has almost no latency, good speed, silent, and it may be possibly just as reliable in that role.
What do you think?
CDMA works for hard drives too! (Score:2, Interesting)
Hard drive makers could do something similar, like spreading the data over a number of physical bits on the disk (such as CDMA does.) Essentially, they would not be limited by the density of the data on the disk, but by the SNR (signal to noise ratio) of the magnetic medium, which I imagine is very high.
Taking this idea furthur, they could bifurcate their encoding methods into 2: a low latency one that retains the characteristics of existing drives, and a high-bandwidth-low-latency scheme which uses digital coding methods to spread each block of data over an entire cylinder for example, and has requires reading the whole cylinder to retrieve a single bit. This would be useful for storing video and large image data, which is retrieved linearly and usually buffered too, and does not require low-latency access the way normal files on a filesystem do.
Hybrid schemes are always better than simple implementations, if they provide a closer fit to reality.

Hard drives are actually vented. There's no pressurized compartment. They run at the same atmosphere as the rest of the machine. The lift of the hard drive heads is the "Bernoulli effect" (http://en.wikipedia.org/wiki/Bernoulli's_equation) see also (http://news.bbc.co.uk/1/hi/programmes/click_online/5413198.stm).
Flash storage is certainly preferable in hard environments, no doubt. But as far as I've seen, I'm not a convert. Useful as hell for digital cameras, PDA's, MP3 players and USB drives. Not so much for primary storage. They're simply not fast enough, usually. I guess some people are making faster ones, but you still can't affordably beat the ol' hard drive when it comes to transfer speed. Seek times, flash wins, but when the transfer rates are as slow as they are on most flash, it doesn't matter.

There's only one problem: this SSD drive costs about $5000.
So we have the technology, we only need to wait until prices come down to reasonable values.
