SSD (Solid State Drive) are enhanced version of your regular hard drives. Enhanced means a much better both in terms of hardware and performance. Unlike regular drivers we get a bit heavy models with spindle, disc and head inside it. Those all work at a prescribed rate to give you better data transfer ratio. There is certain condition to follow while using them. Like they can be affected due to shock or power failure. This makes this drives more responsible for data loss. Physical damage is easier than electric failure. SSD are designed to remove these barriers and give you awesome speed of data reading. SSD does not come with moving parts. They are fixed chips on board offers you high speed flash chips working on low power. The best example of a very small or portable version of ssd is an usb drive. It has a single flash chip inside it with minimal storage value. It works on low power and provides you easy data mobility. You can rely on the drive for small backup solution. Later on came to existence a much higher and cheaper solution called as movable drives. This movable drives offers you storage ability equal to the internal hard drives of a PC.
They work usb support and can or cannot consist of flash chips. It is important to ensure that the removable drive which you’re purchasing must offer you better data transfer ability. I had noticed that external drives with separate power supply support offers you a higher data transfer rate in comparison to those who depends on single source for power. Like usb outlet only. Just for testing purpose I had added an 80GB internal drive to enclosure. It was heavier to carry and bigger in size also. Opposite to it was a 250gb removable drive. I moved 4GB of data at a time. The transfer rate of compact removable drive was slower than the one which was fitted to enclosure. I had noticed many times my friends getting frustrated with slow transfer rate and on the contrary the specification showed a highest transfer rate that you can ever imagine. I do not really like to go in detail. What I assume when I am in a market is choose a good looks portable drive with the storage space I want. But many a time we ignore the hardware specs where transfer rate and hard drive lifecycle does matters. There are certain tips that you can be helpful for you in buying a SSD. Today they are costly.
But in the coming time due to advancement in technology you might get a cheaper solution for the same with better output. The condition to buy SSD is finding the right storage space. Today SSD comes with 256GB support. The much higher size you go for the most costly it becomes. A SSD is capable of offering you more than 600mb/s data transfer rate. You can enjoy awesome speed on it. SSD's are recommended for both pc and laptops. In my branded system you can find ssd as a support for raid partition where the data copy is stored. This gives more durability. SSD's today are choosing as a stronger option for data backup. SSD uses solid state memory which is small black chips. Most commonly called as flash chips. In comparison to traditional magnetic disc SSD offers you no moving part and greater read/write speed. So typically this is safer from physical shock. Because of absence of moving parts it become more stable. Upgrading to SSD in place of traditional drive can be a costly solution today. But it is possible to get an ssd in a laptop. If you are going to purchase a new laptop then you can customize the same and ask for SSD. That might add some to the cost. SSD consume low power. They work cooler and offer high speed. Today there are ample of models in the market which offer you SSD as per different specs. So you might be wondering which the right is for you. Consider that most of the solid-state drive uses NAND flash memory technology, on which we are about to say something about it. This particular technology allows a uniform distribution of the data.
Features:
- Performance - are significantly faster in accessing data
- Reliability - in fact it is less likely that failures occur
- Energy efficiency - net savings in power consumption than normal HDD
- Reduced access time - working in tenths of a millisecond, and you must keep in mind that the access time of magnetic disks is 50 times greater, attested as it is between 5 and 10 milliseconds
- More resistant to damage - according to some specific spread by the same manufacturer has arrived here to a shock resistance of 1500 g
- Longer life - Solid state drives have an average failure rate of less than those of the hard disk
How to Choose a SSD
It is very easy to choose a product or compare it if you know the advantage and disadvantage. The advantage/disadvantage allows you understand what is the good points and limitation of a product. This is applicable for every stuff. SSD comes with advantage and with some limitations also. So if you are confused whether to go for this or not then there are some points that can help you. I had mixed the advantage and disadvantage below on the base of some points. First thing which comes in mind while buying a SSD is that it is thin and easy to upgrade. But remember that SSD lack storage space. The traditional models which are available today are not upto the requirement. Upgrading or buying a SSD needs a much wiser choice. While in comparison to that the traditional are easier to choose.
Transfer Speed
Transfer Speed is the data speed when you move files between partitions or from one drive to another. The speeds differ in each condition. The speed which you are getting while transferring a file between partitions must be entirely different while moving a file among drives. So you need to ensure what you really want. SSD offers you a high transfer power. In a traditional drive there are disc and spindle and head. That means lots of moving part. When you transfer data between partitions the disc rotates a high speed. The speed is defined in RPM (Round Per Minute). For example a regular drive offers you 7200RPM. That means seventy two hundred rounds per minute. The higher it rotates the higher speed you get. But this heats the drives and consumes more power. On the contrary SSD does not have disc. They have flash chips. So it gives you faster speed on the lowest power consumed. SSDs are better always then traditional drivers. Another advantage is the search speed in SSD and traditional drives. When you search some file in your operating system the hard drive rpm define the result time. This is less than a 0.5 millisecond in SSDs. While 15 millisecond approx in traditional drives. This is best for gaming. So this can be counted under advantage.
Cost
Talking about the cost then this is the first disadvantage of this drives. In comparison to traditional drives you can buy a full fledge 500GB ram drive with 7200RMP under relative low cost. The price for a regular 32/64GB drive is four times higher. You are getting speed and durability but on the cost of high price and low storage. Manufacturers are trying to bring at a lower value. Also the price of SSD’s differs based on the memory module used inside it. Some SSD comes with faster memory modules while some comes with slower.
Moving Parts
There are not moving parts in SSD. That gives the distinct feature to it in comparison to other drives. So there are no chances of getting damaged because of head crash. Although that does not mean that the drives will work forever. They usually stops working due to failure of memory module used inside it. Another important feature of this is that SSDs are silent. For hard drives, this is variable, a disc is generally more powerful, noisier. For a system disk, a disk is preferred at 7200 rpm whereas secondary hard drive storage will opt for a hard 5400/5900 rpm. This speed affects the background noise of the hard drive, to which is added an additional noise when accessing the data itself.
