What is the difference between SLC and MLC in solid state drives?

 

You should of try using google for your question . here below I left a link to view , just click on it .

difference between SLC and MLC in solid state drives? - Google Search

 

I still wouldnt bother with either though they are VERY expensive £ per GB and you wont really notice the performance increase regardless what you read.....I had the pleasure of making a system the other day with one and its a waste of money

 

I don't agree there snooker, raise your questions here and you get a discussion. Usually people have a reason for asking and are not just seeking raw information.

 

Just some different points of view on SSD's. They are expensive on a per GB of storage basis. However in an environment where high availability and reliability trumps cost they can be an excellent choice. How much would you pay to know that the probability of a HD failure was reduced by say 70% over time?

In my world managing hundreds of PC's in a demanding environment, downtime equals money lost. When you think about the physics of the issue the standard hard drive is really the only critical moving part in a PC. And the old adage about hard drive failure is very true. It's not a matter of if it is just a matter of when.

When you analyze our help desk calls for Desktop support 68% of our calls are either for hard drive failures, 48% or for MB Component failure, about 20%. This is based on about 4000 calls per year and only includes real hardware issues. In our business we simply keep pre imaged hard drives available and we can swap them out. Most home users don't have that luxury.

Like most technical developments SSD's will come down in price and eventually dominate the market because in the end it will significantly cheaper for PC maufacturers to provide warranty support. It will however take some time and all of the major manufacturers like Seagate and Maxtor will take time to migrate to SSD's.

 

Your point is well taken Cwall. If 48% of all hardware faults are HDDs then 48% of the time there is at least the potential for data loss. Even a complete loss of a mobo, cpu, gpu etc. will not have any effect other than economic.

 

I understand what your saying and normally I would agree but the reason as to why I suggested to use google was there isn't or at least I would believe this be the case, as to, how many people now are using SSD hard drives ? I don't think many are . I'm sure there is but what are the odds now as to how many ?

 

As SSDs cost approximately 9 times more per GB, they will not be widely used and as you say the average consumer has no need for them anyway. The performance is negligable next to high end SATA drives and for that reason I doubt that they will take off to the extent that people think.
As you work in a business environment with servers as do I, you must admit that a backup on a 'non ssd' drive outweighs the cost of an ssd

 

Perhaps the answer is here

Samsung: Solid state will match hard-drive price | Nanotech - The Circuits Blog - CNET News

Which swings in favour of the well developed current technology

Which is a bad thing for SSD future.

But

That I think is where we will see the change over - mass production, coupled with increased demand and technology marching forward will inevitably bring us to mainstream SSD drive use.

 

When one looks at the current state of the semiconductor industry worldwide there is some indication that more rapid development of SSD's could be driven by overcapacity in the wafer fabs.

When you look at the history of cost per MB or GB or RAM you clearly see that pricing competition and the need to keep capital assets producing revenue have driven ever more efficient and lower cost memory chips. However PC technology has in some ways reached a plateau. Faster processor speeds and more memory capacity beyond the limits of what a 64 bit PC can effectively utilize may not drive the consumer market opportunities required to sustain needed growth in sales. This may benefit us as consumers as increased production and availbe fab capacities could be used to produce silicon for the SSD's.

Here is a quote from todays news-
"Micron has announced what looks like a blazingly fast multi-level cell solid state drive (SSD), which supports the 6Gbit/s SATA interface." If nothing else this shows that the chip developers are hot on the trail of this new market.

I agree that I would probably not build my on PC this week with an SSD because it is still so cheap to use the current standard mechanical drives but it's just a matter of time!! The mechanical drive will go the way of the floppy and parallel printer interfaces.

 

the other thing to consider about the HDD is that for about the past 10 years their has been no significant increase in speeds, well they are limited to how fast it spins.

however as SSD technology advances it should over take it's HDD counterpart, and to start with will be expensive but then look at the Raptor range of HDD's and people will pay more for a marginal increase in speed, same with scusi drives so when SSD's speeds overtake the current HDD speeds they will become a viable alternative.

 

Lets not forget about the " Cloud " computing . If this ever take off and becomes the next big tech thing we wouldn't need to have hard drives .

 

Cloud is an old concept that has been 'glorified'

 

Cloud as in intel's cloud chips?

blub blair bub daa dur, to early for that, need more Tea. and Nicotine.

 

Tea, I know we are British Match but get some COFFEE down you will do more Tea ...

 

lol tea actually has more caffeine and themosomethingorotherthatwakesyouup than coffee,

but back to the cloud principal where I thought that type of cloud refered to software that was free of servers and being kept on a specific hardware device.

 

Its an old concept but as the future goes if this ever was to take off or catch on we wouldn't need hdd .

 

There are plenty of devices and hardware that you cannot elimate - the simple keyboard and mice for one, speakers etc.
They do evolve but nothing can replace servers as people want to have something that they can physically control if needed.
