Hi friends, in today's tutorial I will share some of my experience of the recent SSD, I will present a new generation SSD, I will explain how things are in reality, as many paper SSDs are extremely performance, I will do a test to compare SSD last generation one brand new and extremely agile, it is the Corsair Force GT vs 60GB. OCZ Vertex2. Finally we will talk a little about the life expectancy for SSDs, that's because a lot of rumors circulating which SSDs are unreliable, like most myths have some truth of course but things are not like that, SSD are devices highly efficient and highly reliable, the only thing is the price you dezavantajaza GB hard drives here are unbeatable.
Many drives current generation SSDs (mostly) and High End Performance range are based on SandForce SF 2281 controller, this is a high-performance controller but alone is worthless, the controller stores the data in memory NAND flash at the current generation memory is of two kinds, Synchronous and Asynchronous, synchronous and asynchronous in Romanian, this is about how they share data.
Asynchronous memory is cheaper and of course less efficient, while synchronous memory is more expensive, of course this also raises the price of the SSD. I showed you in the tutorial that the price difference is quite important between the two types of SSDs, although the specifications on "paper" are almost identical, it is a little marketing trick that works quite well.we publish theoretical performance of the controller"Would say the PR of a manufacturer.
Below is a very well written article, where you can see quite large differences between seemingly identical SSD drives, but that using different types of Nand (Synchronous vs. Asynchronous)
NAND Flash Faces Off - Synchronous Vs. Asynchronous / hardocp.com
In the middle of the tutorial we present a test Aida64 (formerly Everest) which quite clearly see the differences between the Corsair Force GT and OCZ Vertex2 be noted that there is a SSD Vertex2 some, was a champion a few months ago. I think I never witnessed an evolution accelerated so that what takes place in world SSD now, it will stop where we have already reached the limit of SATA 3 and must take into account that only has SATA 3 implement as the some motherboards. How to horizon not see any SATA 4 will have to resort to PCI Express if you want more speed. My parry is that at this rate should proceed directly to the SATA or 5 6.
Finally we talked about the life of current SSDs, this period can be estimated mathematically, just to know how much data is written daily on SSD, then determine what kind of SSD uses NAND us and we start to make calculations. My current SSD flash is built using lithography on 25nm after I did some calculations I realized that a year my SSD is overwritten by any 20-30 times afterwards Academ 30 5000 of all the rewrites and remain 4970 cycles, with this I still do well 165 years, all this is possible thanks 's wear leveling which helps us to "use" the nand cells evenly. This calculation is of course theoretical, in real life the controller can crack in 10 seconds.
For those who have headaches when doing calculations, we found a small utility that tells us how does he have our SSD
.
If you are looking for absolute performance should be mandatory to system equipped with SSD, the best are those with synchronous NAND.
Recommendations:
Solid-State Drive (SSD) Corsair Force GT 2.5 60GB
Solid-State Drive (SSD) Corsair Force GT 2.5 120GB
Flash SSD Kingston HyperX SSD SATA 120GB 3 2.5
Update
CAREFUL:
I forgot to point out something very important, the application that I submitted it estimated a lifetime 9 years this new years drive computer functioning non-stop, the computer 9 going nonstop for years.

I for one I'm not afraid of SSDs, I fear their price :)) If I had money I would get one but as I remain in my boot time over 1 minute.
I really needed some advice and a presentation that I wanted to get one on SATA 3 if I still have the sandy bridge motherboard I hope it's ok sata 3, do more tutorials like this, that's ok :)
A Tutorial Brand Copyright © Cristian, Excellent! ... worse is that if you want to keep up with technology, you have to give up the villa and BMW ... otherwise we see, I bet that in six months the ssd presented today will be sh ... I'm glad that technology has this rhythm, but in order to keep up, you have to have the undisputed technology: MONEY! ... esteem!
Indeed for many it may be too expensive an SSD, I do not speak for everyone, SSD should put them-n system performance and those who have the means.
We have to look back a little and see that last year prices were much higher, not to mention two years ago.
I do not encourage the use of SSD storage, it is absurd to give a lot of money on a SSD over 120GB, I've got my 60GB, we need greater change in the system caused by a SSD is incredible any component animates not like this system.
As long as we stay with the operating system on the hard disk will not feel his power or components, any superfetch and prefetch sites will invent the people at Microsoft.
We Vevo great uncle input output, we need these bandwidth hungry applications.
Down with the carrion of HDD!
Down with bottle necks!
I vote for SSD!
Vote and you, now!
... I will vote later
Impressive Corsair
hello I have a gigabyte motherboard which is h55-ud2h 2.m would help a sata ssd? sata3 or need to have?
Such an SSD (synchronous NAND controller SF2281 +) SATA2 behave well and, even if you transfer speed will definitely benefit from the high IOPS which is more important than speed.
The price is not large differences between actual and SSDs last generation.
A very nice and useful tutorial. Congratulations Cristi, I liked it! Maybe I'll buy him an SSD when I have money and it will be cheaper ... Until then ... I'm waiting :): D
And do not be pessimistic, you will not die so soon, I think you 30 around for years, yet no time to think of it CV. Be more optimistic! Good health!
I am optimistic by nature, the tutorial just kidding.
Better you bought a primer!
Friends know why...!
SSC OCZ Vertex 3 Series 120GB SATA-III 2.5 inch (OCZ_VTX3-25SAT3-120G)
OCZ Vertex SSD Max IOPS Edition 3 120GB 3.5 inch SATA-III (VTX3MI-25SAT3-120G)
What types of Nand's have (synchronous or asynchronous)??
which is better of the two?
Waiting feedback from experts!
Thank you !
The entire range vertex3 OCZ uses synchronous NAND, the most expensive (3 Vertex Max IOPS Edition) NAND from Toshiba have 34nm, they found that the type of NAND is best in the situation where they had a few complaints from users, they receiving BSOD's from clear.
OCZ Agility uses range from less nand (asynchronous).
I was away from OCZ this time.
Good tutorial, great, just waiting for other interesting tutorials related hardware.
Cristi a question to this Benchmark from AIDA which means that OCZ vertex 2 is better than CORSAIR in terms of performance because I made a difference and ocz is higher so on youtube on some laptops it boots 2 sec slower than corsair force. In connection with this SSDLife :)) how does that program know how much ssd it still has to live for what I get after the software, if it were like this every 2 years I would have to change about 4 SSDs because it "dies" so much he still has to live, that's magic, well, if it's like that, I call it HDD and I'm ready to be safer, HDD is old and old, it's baked well, than SSDs that appeared 2-3 years ago compared to HDDs that appeared from 1998 or maybe older :). To try an ssd on village 3 to see
FRIEND, do you leave comments again without watching the head-to-tail tutorial? I asked you not to post comments so you can get to work. Nobody in this tutorial said that Vertex is better than Corsair and vice versa. I don't know what tutorial you looked at and what you understood but you misunderstood. As for "how does the software know how long the SSD has to live" It was explained in the tutorial
Hey, good tutorial. Amazing speeds. Now technology is developing on PCI Express HDD.
All the best!
