Still, somewhere 10 years ago, an ordinary computer user did not have a question: what drive should I buy for my device? Since at that time, there were only HDD-drives (hard disks). But since 2009, new SSD-drives began to gain popularity, which are fundamentally different from their predecessors.
HDD is a classic drive in which there is a rotating magnetic disk, and a head that writes / reads data to this disk (the technology is similar to the one that was in the record players, but substantially modified).
Since the disk rotates, it has the property of producing a characteristic sound. Data transfer / recording speed is very limited, because the recording head is not perfect, and the disc cannot move fast enough to increase the speed.
HDD – consumes more electricity. And because the magnetic disk is moving, you have to use fans to cool it, which also does not consume energy badly.
Well, plus it’s possible to attribute its value. The cost of this type of drives is an order of magnitude lower than the cost of solid-state drives.
Rarely there are times when a hard drive fails suddenly. Very often, he gives “symptoms”, by which you can judge that soon it can fail, but until that time, the user can make a backup copy of it. Even if the HDD is out of order, it is very often in the workshops, you can restore information from it.
SSD (Solid State Drive), or solid state drive. This drive operates on the basis of memory circuits (the principle of operation, as conventional USB flash drives).
SSD has much higher write speed, reading data than HDD and somewhere in 100 times faster response.
It is much smaller in size than the HDD, it does not warm or hum. The service life is 3-5 times longer than that of a conventional hard drive.
The big disadvantage of SSD is its high price and relatively low volume. I, for example, did not meet a solid-state drive, the volume of which is more than 512 GB. But hard drives for 2 TB, no one is surprised.
If the SSD fails, in most cases, it will simply be impossible to recover information from it. And unfortunately, this type of media can suddenly fail.
Personally, I prefer solid-state drives. I like them, because of their “smart” and lack of noise when working. But if you do not play heavy games and do not use large programs, and it does not matter to you that your computer will not turn on for 20 seconds, but 60, I think it’s worth thinking about whether it’s worth buying a solid storage device.
