What you should know before you buy a new hard drive
Hard disks are still a major component in modern computer architecture and it is normal to buy a new every few years to replace the old hard drive or to use it as an additional disk backup. But with so many options it is easy to be difficult choices.
And if you love to learn something new about technology every day is not superfluous to find out how you can monitor the status of your computer hard drive, as these are great tips for anyone who wants to be prepared for emergencies.
1. Hard disk or SSD
Recently, hard disks begin to lose its charm and gradually replaced by SDD drives. Different technologies, however, have their pros and cons. Generally, SSD are hard drives without any moving parts. The lack of moving parts allows the transfer of data at maximum speeds. Disadvantages of SSD drives is that they are more expensive and impose restrictions on storage.
2. Physical dimensions and interface
The discs are available in two sizes: 3.5-inch and 2.5-inch. Traditional hard drives, data is stored on rotating metal discs, which means that more disks expanded capacity data. Therefore, hard drives for desktop computers are typically 3.5 inches with a maximum capacity of 4 TB, while those for laptops – 2.5-inches with a maximum capacity of 2 TB. On the other hand, SSD, can be made smaller because they have no moving parts. Therefore, most SSD drives are 2.5-inch. Still, if you want to fit a SSD in a 3.5-inch connector, you can use adapters.
As for the links, most contemporary consumer devices – such as an HDD and SSD – using SATA connectors. Older hard drives that were created before the advent of standard SATA, will probably use IDE connector. And if you bought an external drive, it will connect to your system via a USB port.
3. Specifications and performance
– Storage Capacity: Hard drives come in all sizes, not exceed 4 TB due to physical limitations. On the other hand, SSD drives are much smaller and have not yet been able to pass the range of 1 TB. Even so, the needs of consumers rarely exceed 512 GB.
– Transfer speed: Consumer needs are determined by many factors, but RPM (RPM) is important. Higher speed means faster data transfer to and from the device.
– Cache or buffer: When a hard drive should transfer data from one point to another disk, it uses a special area of internal memory called cache or buffer. Larger cache will allow data to be transferred faster. Modern hard drives can be the size of the cache memory ranging from 8 MB to 128 MB.
– Percentage of failure: Since hard drives are mechanical, eventually they wear out. But not all models are identical hard drives. Some models must be replaced every 6 months, while others have a life expectancy that exceeds 6 years. It is your responsibility to understand and model the production company before your purchase. Overall, however, HDD are more reliable than the SSD.
4. External or internal drives
You should be aware that each drive can be used as internal or external, as long as the connectors are compatible. External drives are ideal for storage and archiving. They are usually joined by means of a USB 2.0 cable, which provides a 480Mb/s, but more recent models can support USB 3.0 and provide 5.0Gb/s. External drives are portable. They can be shared between multiple computers without hassle and complications. Simply disconnect the USB cable and connect it to another location and you are ready. They may also be included in TVs and media centers for playback of multimedia files.http://szlifestyle.com/sz/2015/03/30/what-you-should-know-before-you-buy-a-new-hard-drive/https://i1.wp.com/szlifestyle.com/sz/wp-content/uploads/2015/03/sz_external-hd.jpg?fit=639%2C477https://i1.wp.com/szlifestyle.com/sz/wp-content/uploads/2015/03/sz_external-hd.jpg?resize=150%2C150TECH NEWShdd,SSD,TechnologyHard disks are still a major component in modern computer architecture and it is normal to buy a new every few years to replace the old hard drive or to use it as an additional disk backup.
