For the first time, scientists at IBM Research have demonstrated that a relatively new memory technology, known as phase-change memory (PCM), can reliably store multiple data bits per cell over extended periods of time. This significant improvement advances the development of low-cost, faster and more durable memory applications for consumer devices, including mobile phones and cloud storage, as well as high-performance applications, such as enterprise data storage.

I'll buy a "flash" drive when it will be using this tech. I really hate the fact that you are still constantly thinking of those write cycles. Where with regular HDD, you never bothered since they have pretty much unlimited writes. But with 30 million writes, that's something completelly different. I hope this will end up in consumer devices quickly and with more reasonable price.

So if heat is the way to change the memory what is the threshold before it changes in a black phone on a hot 100+ day?

Ha, sucks to be someone who bought an SSD now. Of course, it'll take a few years but who cares?

Wait! A thought just crossed my head! (it kinda hurt) What's the average price difference (per GB) between an SSD and a hard drive? And then what's the average speed difference between the two? How much would it cost to buy, say 1 TB hard drives and set them up in RAID 0 (?) before you reached the speed of an SSD? How much space would you end up with?

Ah, my mind is flooding!

u can raid 0 as many as you want, you wont match an SSD for access times (which is what gives an SSD its speed advantage) even if you raid 100 disks

How are they cheap? The only remotely affordable ones are too small to be used as a main drive. Even if I offload my pictures, videos, documents, downloads, and music to a HDD I still need at least 256 GBs to fit all my installed programs. Which is currently in the $400-500 range. Getting some little 60 GB is just stupid. You're basically just decreasing your boot time (most only reboot once a month) and startup of 5 or less programs/games. That's just a waste. SSDs are still relegated to gimmick status until that cost per GB changes.

Haha, you gonna stick to mechanical hard drive for another 5 years?

I'll probably buy 3 or 4 new systems with ssd's in that time.......waiting 5 years for technology is like waiting for Jesus to return......(no offence to religious peoples)

now really do you care about loosing 10 sec. from your time? not to mention the price diff.between them...

SSD is still expensive /Gb compared to classic HDD and people don't really jump in to buy and this will remain till the storage price/gb will be v.close between them

I only have a 2TB WD Caviar Black and i'm perfectly happy with it. System boots up in under a minute anyway for moments when i actually don't use Hybrid Sleep which wakes it up in few seconds.

I only see point in buying SSD is for either netbook or notebook. In those devices in makes loads of sense. But in desktops, only if you have loads of money. Which most don't...

Most people who say this haven't tried a ssd and all want one when they try it. It happened with 2 friends, at first they said a ssd is so expensive for the performance you gain, it has to be cheaper first before, bla, bla bla. Then they tried my pc and now both of them they have one.

No need to defrag, no need to format, no noticeable performance degradation over time. I haven't defraged or formatted my pc for a year and a half now and everything is like the first day.

It took NAND flash about 22 years to get mainstream, at least if you judge today's SSD's as mainstream.
2016 is an ideal, but it is not a feasible reality.
Difference today is the huge market demand for flash-type memory.

Capitalism works, and works very quickly.

Big part of why I got one is NO MOVING PARTS, read write times def but I want my comp to be able to withstand years of 24/7 abuse w/o burning thru hdd's(even tho right now I'm babying my gaming rig my htpc is still running 24/7)

Sure, if you have a basic computer but you have a high performance expensive computer, you should be able to afford a small SSD.

SSD's are a noticable improvement over hard drives. Quicker booting, quicker installation of programs, quicker loading times for games, quicker at moving files, quicker at everything.

Its not just booting times...

When you try one you will understand....
