SATA 1.0 vs SATA 2.0 vs SATA 3.0 : The hunger for speed
1. Today technology runs faster then u blink. Today when someone has not even come to terms from IDE TO SATA 1.0 and when mostly have not even heard of SATA 2.0,in comes with a bigul siren SATA 3.0.YESSSSS!!!!with a whooping 6 Gb/Sec, and a range of new features for bandwidth intensive users, a much rapider future lies ahead. SATA 3 is bound to increase the interface speed but to fully realize its potential the viscera of a hard drive need to get quicker. 2. SATA 3 introduces changes including "a new Native Command Queuing (NCQ) streaming command to enable isochronous data transfers for bandwidth-hungry audio and video applications, better power management, and the connection mechanism for compact devices with connectors designed for the smaller 7mm optical drives in laptops and a Low Insertion Force connector for 1.8-inch drives. 3. Thanks Digit again!!!!
INTEL vs THE SEVEN SAMURAIs
1. The old story of “MUTTHI MEIN TAQAT" has come up with a new version in the 21st century in the form of SEVEN SAMURAI
2. Dysphoric with Intel’s dominance in the sector, the conglutination of processor designers and manufacturers has teamed up to develop a revolutionary new microprocessor. The coalition is led by the recent merger of NEC, Renesas ,
3. The new microprocessor will be based on innovative energy-saving software. The final, commercial CPU will run on solar cells; it will be smart enough to use only as much power as is needed for the data being processed at the time; and it will remain switched on even during power cuts. A prototype is reported to be running at 30 percent of the power of current CPUs and remains ON even when mains power is cut. This new standard, along with the CPU is likely to be introduced in 2012.
4. Come on ….come on brains of the world…fight more with each other for consumers like us who wish to get the best!!!!!!!!!!!

SSDs vs HDDs : WHO is GOOD?
2. If you have just bought a shiny new SSD, it isn’t likely to continue performing at blazing speeds after some usage. An empty drive will always perform better than one written to. The good news is that after an initial dip in performance, SSDs tend to level off. Even if they do drop in performance over time -- undercutting a manufacturer’s claims -- consumer flash drives are still vastly faster than traditional hard drives, because they can perform two to five times the input/output operations per second of a hard drive.
Why does performance drop?
3. Unlike a hard disk drive, any write operation to an SSD requires not one step, but two: an erase followed by the write. When an SSD is new, the NAND flash memory inside it has been pre-erased. But, as data is written to the drive, data management algorithms in the controller begin to move that data around the flash memory in an operation known as wear leveling. These algorithms are used to more evenly distribute data across flash memory so that no one portion wears out faster than another, which prolongs the life of whole drive. Even though wear-leveling is meant to prolong the life of the drive, it can eventually lead to performance issues. SSD performance and endurance are related.
4. Generally, the poorer the performance of a drive, the shorter the lifespan. That’s because the management overhead of an SSD is related to how many writes and erases take place. The more write/erase cycles there are, the shorter the drive’s lifespan. Consumer-grade Multi-Level Cell (MLC) memory can sustain from 2,000 to 10,000 write cycles. Enterprise-class Single- Level Cell (SLC) memory can last through 10 times the number of write cycles of an MLC-based drive.
What Matters ?
5. ALGORITHM : A read-modify-write algorithm in an SSD controller will take a block about to be written to, retrieve any data already in it, mark the block for deletion, redistribute the old data, then lay down the new data in the old block.
6. Some manufacturers use algorithms that combine writes to more efficiently use NAND flash memory space; others use cache to store writes in order to lay them down more efficiently.
7. BUGS : Bugs Can Cause Slow-Downs, Too Intel’s X25-M SSD had a firmware bug that led to major fragmentation problems that dropped throughput dramatically . But what’s clear is SSDs need more development to address these long term performance issues.
