.A popular advantage of solid state drive (SSD) over conventional hard disk drive technology is the absence of moving parts making SSDs more stable and durable. Get the best deals in Hitachi SAS SSD Drive in UAE.
These storage devices are designed to have the same interface as the hard disk, which is an electromechanical device with spinning disks and movable read and write heads. Because of this similarity in interface design, SSDs can easily replace hard disks in storage applications.
What is SSD?
SSD stands for solid state drive, and sometimes referred to as a solid state hard drive. Solid state drives are quickly gaining in popularity.
Solid state hard drive technically is not an entirely accurate term, which is solid state drive, as a standard hard disk drive is being replaced. Simultaneously solid state hard drive does in essence describe the function of a an SSD as a solid state drive is a direct replacement for the hard drive in your desktop or laptop.
Why would you want to replace your hard drive, with a drive that has less than half the storage capacity, and costs at least double? Well, if that is the only concern of yours, sticking with your hard drive may be the right choice for you. Even for additional storage, it is hard to look away from the reasonable prices for hard drives, especially when compared to a solid state drive.
So what is the point of a solid state hard drive replacement? Performance – a solid state drive will significantly improve your computers speed during all operations. This is the case during start up, running programs, and shutting the computer down.
What is the benefit of an SSD?
Solid state drives speed up your computer during start up, while running multiple programs and during virus scans you will notice a significant difference compared to that of your standard hard drive. The prices of SSD’s have been falling quickly, so now they are more accessible for everyone.
A solid state drive is not something recently invented, the reason they may seem a new product is that the price for an SSD was more than most consumers were willing to spend for a performance upgrade, while giving up storage space.
Business owners are starting to realize that the time saved with a solid state drive adds up, and more than pays for itself. The added comfort and efficiency of not having to wait as long during computer start up and general operation is also an alluring quality in general.
Core Components of the Solid State Drive
The most basic components of a solid state drive are the controller and the memory for storing data. These two components are the most crucial factors that will affect the performance of the device. Other components present in the SSD play lesser significant role in its overall performance.
The controller in a solid state drive device contains the minute processor for executing codes instructed within the firmware. The processor together with the firmware code is responsible for performing error correction checks and read-write caching. Encryption of data is also carried out through this bridge. Common storage problems are also avoided by the wear leveling and bad block mapping functions of the controller.
Another primary component of the solid state drive is the memory that currently uses the NAND flash non-volatile memory technology first commercialized in 2009. It is cheaper compared to the DRAM-based technology, which was popular before the year 2009. Another benefit of integrating flash memory is its ability to retain persistent data even after sudden outage of power supply.
Solid State Drive Form Factors
Since solid state drives are designed to have the same interface as hard disks, these devices follow the same form factor as the standard hard disk drive such as the 5.25-inch, 3.5-inch and 2.5-inch size specifications. While hard disks are restricted to the size of the rotating disk, SSDs offer better design flexibility and shapes can be virtually anything imaginable. Other popular form factors for the SSD are box, bare-board and ball grid array shapes.
The solid state drive memory device outperforms the traditional hard disk in every aspect of memory technology. With more emerging developments continually commercialized, costs for SSDs shall become cheaper in the years to come.
This may seem unjustified for the average computer user, but for individuals who just need that performance, a solid state drive is the way to go. Additionally for entrepreneurs who consider time extremely valuable, and don’t like to lose even seconds of their time, they will want to at least weigh in a solid state drive as a consideration.
For everyone else, who just thinks it would be nice, but can’t justify the price, there is hope for you as well, for the prices of solid state drives are dropping steadily, and in the near future, they may either be reachable for you, or your next PC purchase may not be too far out of reach where you can’t afford it.
Although hard disks are slowly declining in popularity especially in high-performance applications, ordinary storage requirements would still prefer the older technology because of the current high price of SSDs. With more technological breakthroughs achieved in semiconductor fabrication technology, however, SSDs are expected to decline in costs gradually.
Tips For Choosing The Best Solid State Hard Drive
Despite their higher cost per megabyte of storage, there are many compelling reasons to upgrade a system with a solid state hard drive. Accessing information from a solid state hard drive is much faster than from a traditional hard disk drive. They also operate in complete silence, weigh much less and have very low power requirements. The high prices make them unfeasible for using as a large storage solution for most users. But for the laptop and netbook market they could be the perfect upgrade. Quite a few brands are now available and each have their own advantages and disadvantages. Depending on how much a person is willing to pay and what their needs are.
Corsair Force Series GT
The Corsair Force Series are high performance solid state hard drives with read speeds up to 555MB/s. Corsair have also made this range of drives capable of handling several system upgrades by making them SATA 3 compatible.
Expect to pay a little bit more for the high performance with the 60GB version. That is coming in at a little over $100. Despite a slightly higher entry level price than other brands. These are still a little cheaper than the Intel X25 range.
With a reputation for being a little less reliable. The OCZ Vertex range of SSDs are still a great entry level device for those on a tight budget. You can expect to get up to 50,000 IOPS, which is a little slower. Than the Corsair range, but most low end users will not notice a difference. They also have updateable firmware, which is an excellent feature for such a budget range of SSDs.
Performance is still pretty good with read speeds up to 250MB/s in the 250GB models. Write speed of 160 MB/s.
Intel have the lowest failure rate of any brand so far to date. Making these the perfect drive for the user who has mission critical applications and data on their device. Meantime between failure for the X25 range is in the order of 1.2 million hours, which is impressive. The low failure rate makes them perfect for high end servers where accurate data storage is critical.
With a performance specification in the range of 35,000 IOPS. They are certainly not the fastest piece of kit. But they more than make up for this in their reliability. Reliability comes at a price however, as you can expect to pay. A little over 200 dollars for an 80GB model.
Choosing the right SSD will invariably come down to price versus features. With the rising popularity of solid state hard drives, and improvements in controller chips. More efficient reading and writing algorithms, we can only expect to see lower prices. Greater reliability and storage capacity, as well as faster performance.
