SSD: advantages and disadvantages We are used to store information in the computer hard disk drive.But modern technology does not stand still, so in addition to hard disk is used, and other types of memory devices, such as solid-state drives.What are the advantages and disadvantages of SSD compared to the usual hard drive?

First, let's look at what is a solid-state drive ( SSD drive ).This memory device is based on the memory chips.Drives SSD may be based on the flash memory or memory, such memory (RAM).SSD also includes master controller.Unlike hard drives, SSD has no moving parts .

Usually these drives are used in compact portable devices : smart phones, smartphones, netbooks, laptops.This is due to their smaller size and weight compared to conventional hard disks, as well as lower energy consumption.

have SSDs has its advantages and disadvantages compared to hard drives.Let's start with the positives.As mentioned above, solid-state drives have no moving parts, the less moving parts - the lower the chance of breakage.Also thanks

to this SSD drives operate silently .

SSD more resistant to mechanical damage , it is less sensitive to external electromagnetic fields and has a wide operating temperature range, so no need for additional cooling.

SSD drives use less power , and this increases the operating time of portable devices from the battery.The small size and weight of solid-state drives also makes them suitable for use in portable devices.

speed read and write information often exceeds the capacity of the hard disk interface, and while reading the file remains stable regardless of the location or file fragmentation on the disk.

But SSD has its drawbacks - which is why he was not replaced conventional hard drives, and is used along with them. main disadvantage of SSD drives - a limited number of write cycles .Depending on the type of memory, it may be 10 or 100 thousand times.

second drawback - it compatibility issue some versions of the operating system Windows .The fact is that most versions of Windows work with SSDs as well as conventional hard disk drives, for example, using the mechanism of the swap and disk defragmentation.These operations are good to work with a conventional hard disk drive, solid state drive but, on the contrary, wear out and reduce the service life.

So if your laptop or netbook SSD installed, you need to disable any file operations, designed to work with hard drives, or install the operating system Windows 7 : it is specially optimized for SSD carriers.

Another drawback of SSDs - their high price .Price 1GB SSD drive prices above 1 GB HDD media (hard disk drive).The cost SSDs increases proportionally to the volume, whereas the price of traditional HDDs increases slowly and does not depend on the volume and number of plates.

compromise intermediate option between SSDs and traditional hard drives - the so-called hybrid hard drives (HHD or H-HDD) .Such a medium includes a hard disk drive (HDD) and a small amount of SSD.

SSD acts as a cache (intermediate buffer for frequently requested information) and helps to increase device performance, service life, and lower power consumption.As SSD media, hybrid drives are mainly used in portable devices.

SSD yet can not fully replace familiar to us hard disks , but for use in portable devices, it is very convenient.And as progress is not standing still, perhaps, soon we will have to deal with more advanced types of storage - can only wait.
