SSD Price Drops Signaling End of Spinning Media?
gjt writes "When Intel and OCZ recently announced new 'affordable' Solid State Disk drives — offering a meager 32-40GB — we initially yawned. But, then we took a closer look at the press releases and the in-progress research and development in SSD technology and opened our eyes. While the new drives aren't affordable on a cost per gigabyte basis for everyone, it does set a precedent — and most importantly a barometer price of $100. And it really does start the death clock for hard drive technology."
In 5 years, people will still be maintaining COBOL systems.
Price is only the first hurdle for SSDs. There's also the issue of reliability, and reports from the field suggest that SSD reliability is highly variable, and in no case as good over the long term as hard drives. That will probably change in time, but they're not there yet.

Helicopters signal the end of automobiles, just as soon as their poor $$/mile traveled ratio reaches parity, but you can buy helicopters from Air Hog right now!
Solar panels signal the end of nuclear power AND the oil industry, just as soon as their poor $$/watt ratio reaches parity! But you can get a solar powered calculator RIGHT NOW!
Can I be a tech pundit yet?
Pity the lesson of Y2K went unheeded - where every COBOL programmer was paid whatever they asked to fix their code, but after should have all been taken out to a field and shot in the head.
Why shoot the programmers? Why not shoot the managers too ignorant to modernize their code base?
To get back on topic, I see spinning drives as the new backup or large file storage medium. You boot off your SSD and keep most of your files there, but anything you want a backup copy of or anything large enough to not need fast access, like movies, pictures, and music get stored on the HDD.
There is no "I disagree" mod for a reason. Flamebait, Troll, and Overrated are not substitutes.
That is a really persistent myth (that magnets will erase/corrupt data on a modern hard disk drive).
.40 or .45-caliber round through a platter, you can be certain the data is unrecoverable. Last time I checked, HDD platters are made out of some sort of silicon composite, so a bullet should shatter the entire plater (or at least half of it) into tiny fragments.
Inside of all harddrives for the last 10 or so years are multiple, very powerful neodymium iron boron magnets that move the actuator arm over the surface of the discs. If magnets outside of your drive would erase data, then surely these intensely powerful magnets inside would do the same, no?
The most conclusive testing I've seen done on this was several years ago. A guy had stacks of dead hard drives, and he decided to harvest the magnets from them. He had a stack of 50+ very powerful NIB magnets. He then took a working HDD, full to capacity, and covered the entire hard drive in them- front and back, with layer upon layer of magnets. Then he set the drive in a desk drawer for a few weeks, after which he plugged the drive up, and all of his data was still completely intact. Not 1 file was corrupted in any way.
Now, if you put a
Yeah, if you really want to compare apples to apples, measure MTBF.
Oh, and let's not forget the SSD's far superior ability to decay gracefully.

I wonder how long it will be before SSDs lose the traditional 3.5" form factor. There's no reason why you couldn't say, drop the guts into a PCI form factor. That cast aluminum enclosure is probably $3-5 of a product that probably costs $45 to make. With less heat and mass requirements it's likely we'll start seeing naked chips on a breadboard to save 8-9% of the manufacturing cost.
moox. for a new generation.
Wrong.
A full Win 7 Ultimate install with Office 2010 + Visual Studio 2010 + Project & Visio 2010 sits at around 25GB.
you still have 15GB left. Take off VS2010 and you are sitting around 20-25GB free.
The point of the shift to 4k sectors (e.g. the WD "Advanced Format" drives) is that the amount of space needed for error correction at ever increasing densities was entering into the bounds of diminishing returns. Larger blocks mean less error correction is needed and thus more storage space for a given platter density. Anand has a pretty good writeup on it here: http://www.anandtech.com/printarticle.aspx?i=3691

On the other hand, you only need to install Windows ME, and you promptly get a fanless system.

Here, too.
My basic "swap cycle" for hard drives was
1) Buy them
2) Use as data storage 2-3 Years
3) Use as OS drive 2-3 Years
4) Use for swap space 2-3 Years
5) Throw them out
I have gone through maybe 25-30 drives for various boxes at home so far, and exactly ONE has failed me so far, while it was already on "swap space" duty. Usually the ones I throw out are about 8-10 years old, just because they are now even to small to be useful as swap space.
A lot of things can change in 10 years. Just think back to the year 2000: computers only ran at 2-3 GHz and Linux was just getting into the mainstream!

You don't remember the days of limited storage, do you? Those 2 extra bytes times 100000 records * 20 date fields was 1/10 of your drive back then.
Now get off my lawn!
Peter predicted that you would "deliberately forget" creation 2000 years ago...
Oh, the ignorance of youth. Computers were over fifty years old in Y2K, and your cell phone is more powerful a computer than any built in the fifties. Hell, a Hallmark card is more powerful and sophisticated. They used two digits for years because they had to. There simply wasn't enough data storage (which oddly makes this otherwise offtopic comment on topic). You take your terrabyte disk drives and your gigabyte SSDs for granted, but early system were measured in kilobytes.
An example is the IBM 1401 that was announced by IBM on October 5, 1959 (I was seven years old at the time).
Legacy data and cheapassed managers kept the two digit dates around, and programmers and systems analysts warned management of the coming doom, but were ignored until it was almost too late.
A COBOL programmer in the 1950s would be dumbstruck by what we have today. Actually, I'm dumstruck as well; cell phones, flat screen computers, and self-opening doors in Star Trek were impossible; science fiction. You young folks can't imagine how primitive things were when I was a kid, and nobody dreamed we'd see SSDs.
