Hi friends, in this video tutorial we will talk about SSDs SSDs are some revolutionary and advanced storage devices, which will replace the old ladies while hard drives are built exclusively of NAND flash chips (as a as USB drives), no moving parts and therefore are resistant to shock and very fast.
SSD technology is at the beginning but the performance is far superior to that of a conventional HDD, SSD first access has a very small SSD that offers extremely low latency when reading and writing small files while the hard drive has serious problems when it comes to small files.
NAND flash chips used to build SSDs are two types, SLC (single level cell), there is one bit of information stored on a cell SSDs built with SLC flash are quite expensive and have smaller capacities , performances are very good, they are mostly used in the enterprise, to servers and professional workstations, where performance and durability are the most important, SLC flash is extremely durable, withstand several cycles of rewriting .
The second technology fososita build MLC flash chip (multi level cell) on these chips can store multiple bits of information in a cell, most often store two bits of information at a cell flashes MLC have worse performance but it has high capacity and low prices, SSDs built with MLC flash chips are the most common in stores and it is likely that you also buy an SSD everything that is based on MLC flashes .
SLC withstands 5.000.000 write cycles (100.000 per cell) and MLC only 1.000.000-2.000.000 write cycles (10.000 per cell), more on Romanian, an SLC-based SSD has a much longer life than an MLC-based SSD, of course, first of all you have to afford an SLC, if you can't afford it you can go for the MLC flash, the specialists work more focused to improve the MLC flash.
In this video tutorial are presented the technologies underlying the SSDs, these technologies are: Wear Leveling Technology, Error Detection - Correction, Bad Block Management, SMART Technology, NCQ Technology, TRIM etc, TRIM is the newest and most important technology, it will help in time to maintain the performance of the SSD and to reduce the error rate faced by the controller, for now only windows 7 has this function included, in principle it is about better cooperation between the operating system and the controller When the SSD deletes a file, the operating system immediately notifies the controller that a file has been deleted and it will know what to do, without wasting unnecessary resources, it will go to safety.
The tutorial also presents some SSD models that have a very good value for money, of course these models are recommended during this period, after a while things will change, these models are indicative, our advice would be to consult the specifications of on the manufacturer's website before purchasing an SSD.
For details on the life of an SSD can read the following article:
What is the lifespan of an SSD?
Also in the article you will understand a picture, how things Wear Leveling technology, which is introduced in the new generation of SSDs.

Nice, but it's a better drive.
Why is that?
Hard Disk is cheaper, is more spacious, but I do not think that is better.
very good presentation. I also have a question, I'm thinking of myself taking a 1 TIB or 2 500 GB hard drive, how do you recommend it to me?
Do yourself a reckoning, see how out cheaper, they also see that the performance of 500 performing gigs and what is the terra 1 for performance you have to go on the manufacturer's website.
Sall. I also have a question: D you could do a tutorial on how to make a style sheet for a site. I think the tutorial would be great. Anyway, I don't think you will be able to do that in one tutorial. -should be more .... Spersa you can do :)
And I would like asra because those topics on wordpress are not who site what ...
hello I have a question cristi.am an account after you download iPlay and leave them seeding and no longer upload what the cause might be?
on the other trak as isoHunt, Mininova, last but iPlay nu.puteti upload torrents to me and answer me?
please....
I'm not expert, but from what I hear, it's choppy SSD data retention time, although it breaks the speed HDD compartment.
Does not take advantage linuxistii also incredible performance??
SSDs will run on Linux, but I do not know if introduced Linux support TRIM technology, even though there are sure this time will be introduced very soon, the fact is that when you go to buy an SSD, you should inquire if TRIM support, it's a shame not to buy an SSD with TRIM, so you can receive a bonus of durability and stability.
Linuxistii have time to take advantage of these technologies outside of Cristi currently do not know anyone to have an SSD in Romania, are very expensive and not affordable to every pocket, you will probably be widely used and will turn their attention Linuxistii to these other SSDs currently prevails now.
Beautiful presentation.
Thanks for the information :)
@ Augustine: R be super useful tutorial about how to make wordpress themes ;)
I have a problem I Stay cathode when I playing a game or edit video and give rendering or game screen BSOD appears I close my pc and I BSOD appears
Previously I change my Stay at 1 GB GB 4 I put one LinkWord I changed the source of the previous W 580 480 W was all LinkWord.
And do not know what I could have got a few times and messages RSOD really do not know what it could be.
Stay changed? Rami think I errors? Put on old or source?
Or to be the video card? Or incopatibilitate between Rami and processor?
Thank you!
Can also be from memory and from the source, take it and you elimination, try with other memories and another source, see if you do, otherwise you can not figure out.
fb tutorial for boot and others esi a video on YouTube about that, but I'll take my 5 an SSD over years when it will be cheaper, are very expensive in space we offer a cost SSD 1 7000 tb euro plus poor reliability over time, some say as she lowers memory defective cells are locked, so you lose and space. but like everything in this world has advantages and disadvantages, advantages super performing read, write, access, lack of noise, Cara in pc, price and reliability disadvantages, but this is solved in the coming years while
I do not agree with SSD storage at this time a suitable SSD only system possibly can partition for a dual boot.
The recipe is as follows:
SSD operating system.
HDD for storing files.
Hard drive will not disappear anytime soon, will remain an unbeatable storage solution, the price / gig hard drive is favorable classic and I think it will stay that way long.
