Hard drives are getting faster and the competition for speed and storage is heating up. At CyberCall Computer Repair Bristol we find it always helps to understand the latest technologies, which is why we have knowledge in a whole host of different areas.
Basics of Hard Drives
Traditional computer hard drives, called hard disk drives (HDD), use a magnetic platter rotating at high speed to store data permanently. A magnetic read/write arm extends over the platter and accesses or writes data to unused portions of the drive when a new program is installed or a file is created. Unless disrupted by another magnetic field, the data on these magnetic disks is permanent.
Solid state hard drives store data permanently as well, but without the use of a magnetic disk. Instead, they use flash memory that retains the information even after the power has been disconnected from the computer. This flash memory, similar to, but not the same as USB flash drives, is capable of close to 100 times better performance than a traditional hard drive.
Advantages of SSDs
Solid state drives are fast. Compared to traditional hard drives, SSDs can boot an operating system from a cold start in just a few seconds. In benchmark tests found across the web, solid state drives consistently outperform traditional hard drives in both cold system starts and application opening times.
Traditional hard drives function best when data is written in a long, continuous string of magnetic sectors. Fewer movements by the read/write arm allow them to read the data at high speed and not have to search for remaining pieces of an application. As hard drives fill up, these big uninterrupted sectors are harder to find and data fragmentation, or the placing of an application in multiple sections of the drive, occurs. Solid state hard drives don’t suffer from fragmentation, as all of the data stored on flash memory is equally easy to access at all times.
Another advantage to using a solid state drive is durability. Unlike a hard disk drive with a magnetic platter and a read/write arm to worry about, solid state drives don’t have any moving parts that can break if the drive is dropped, meaning better data protection in the event of an accident. Dropping a traditional hard drive could mean the end of the data forever if the magnetic read/write arm becomes inoperable. Should you have any concerns over lost data, contact one of our data recovery specialists in Bristol for more information on retrieving data you may think is lost forever.
While solid state technology hasn’t yet caught up to traditional hard drives or cloud storage in terms of space, new innovations are quickly making them the king of storage.
