Advantages and disadvantages of mechanical hard disk and solid state drive

Solid state hard disk advantages: fast read and write speeds, shock and drop resistance; solid state hard disk disadvantages: data loss is not recoverable, expensive. Mechanical hard disk advantages: large capacity, low price; mechanical hard disk disadvantages: slow transmission speed.

One of the advantages of solid state hard disk

1, fast read and write speed. The use of flash memory as a storage medium, read speed relative to mechanical hard disk faster.

2, shock resistance. Traditional hard drives are disk-based, with data stored in disk sectors. And solid state drives are made using flash memory particles (i.e., mp3, U disk and other storage media), so there are no mechanical parts inside the SSD hard drive, which can minimize the possibility of data loss in the event of collision and shock.

Two, solid state hard disk shortcomings

1, data loss can not be recovered. Solid state hard disk in the data security is also a disadvantage, may lead to data can not be recovered, but the mechanical hard disk damage, generally can also be data recovery, from the data security, mechanical hard disk also has the advantage.

2, expensive. Although after years of development, now the price of solid state hard disk has been much cheaper, but undeniably yes, solid state hard disk unit price per GB than mechanical hard disk unit price per GB is still much higher. I believe that in a few more years of development, the price of SSDs will definitely come down.

Three, mechanical hard disk advantages

1, large capacity. For mainstream users, the current cost-effective is 1T, 2T mechanical hard disk, but also the best capacity choice. Therefore, we can choose the right capacity according to their own needs when installing the machine, general home, office, game users, choose 1T or 2T capacity on the right.

2, low price. Compared to solid state drives, mechanical hard drives are more affordable. Although SSDs are now coming down in price, they are still much more expensive than mechanical hard drives.

Four, mechanical hard disk shortcomings

1, slow transmission speed. The speed is much slower compared to solid state, and security is not high.

Mechanical hard disk purchase matters

1, the capacity of the hard disk. Capacity is the most intuitive parameter of a hard disk, and today the maximum single-disk capacity of a hard disk has exceeded 1TB and is moving towards the next watershed. Such a high single-disk capacity makes today's maximum hard disk capacity can reach more than a dozen TB. Of course, for the average user, a 1TB hard disk is already enough to use. For users who like to download information or videos from the Internet, a 2TB or larger capacity 4TB product may be more appropriate.

2, the brand of the hard disk. Now on the market common hard disk brand: Seagate, Western Digital, Hitachi, Samsung, Toshiba and other brands, which Seagate due to the higher performance-price ratio, so that its market share is far ahead. Western Digital, Hitachi and Samsung follow and offer 2, 3 or 5 year warranties on some of their products. The most used and top-ranked brand is also Seagate.

3, hard disk speed. There are two main types of hard drive speeds on the market today, one is 5400RPM and 7200RPM, and 7200RPM is the mainstream, higher performance, so we generally buy 7200RPM products, of course, the higher the speed, the higher the performance of the better.
