Computers function pretty much the same way that we do. Like us, they too need a place to store information. The same goes for your smartphones. There are three types of storage: primary, secondary, and tertiary. Among these, only the first two are widely and commonly used.
If compared to us, the primary storage is much like our short term memory (STM). It’s the memory that a home cook uses to remember what she needs in the storage room and forgets about it when she’s back in the kitchen after fetching what she needed. In other words, it’s a temporary memory. The secondary storage, on the other hand, is what is known to be the lasting memory. Let’s take a closer look at each of them.
Primary storage is basically the internal storage of your computer or smartphone. You will recognize them as the RAM or random access memory in your device’s setting.
Secondary storage is what is mostly known as external storage drives. They are the “outside” drives used to store data with the exception of the hard drive. The hard drive in your device (computer or laptop) is built within the device. But it does not count as primary for the reason that the CPU cannot access it.
Tertiary storage, the lesser-known and used storage, is so because it is only used for massive amounts of data including old data that has to be stored. It is slow and involves a robotic instrument to transfer data.
What used to be just the internal hard drive now has a brother - the external hard drive. Many are finding the advantages of an external hard drive mainly because of its spacious storage. CDs and DVDs are still around but they are less likely used because modern laptops especially small ones have bailed out on the disk reader/writer drive. Flash drives or commonly known as USB are the more preferred medium of portable storage as well as memory cards.
Data storage is a big deal. A lot of storage options are available now compared to a few decades back. If your storage devices like your hard drive are giving you a hard time, don’t worry. https://www.harddriverecovery.org/hard-drive-recovery-service.html can more than help with that.
