SSD hard drive guide

A SSD represents an electronic storage medium for data processing. This is based on semiconductor technology. It can be classified in the category non-volatile storage drive. This means that the data stored on the medium can not be lost in the event of a power failure, but it is retained. As an example of volatile memory is the memory, which is emptied each time after switching off the PC. SSD hard drives are by no means as susceptible to mechanical interference as their magnetic counterparts. In addition, you have shorter access times and a lower noise level. The advantages and disadvantages of SSDs compared to magnetic hard disks are briefly described below.

Advantages of SSDs
– faster access times for faster booting and working
– Less shock and temperature sensitive
– less heat generation and power consumption
– independent of physical dimensions

Disadvantages of SSDs
– Compared to magnetic hard drives already more expensive
– may under no circumstances be formatted

What to buy a SSD should be noted

capacity
The time when you just have the appropriate operating system on one SSD is over, is over: Today, the capacity spectrum starts at 120 gigabytes. Thus, it is possible to store some data on an SSD. If you’re looking for future-proofing, it’s best to invest in a two-terabyte SSD hard drive. Thus, one has enough space, so that numerous, equally large files can be stored on this fast drive. The disadvantage is the price: An SSD with two terabytes of storage space costs as much as some complete computer. The SSD price development of the past few years shows, however, that such plates will soon be affordable. One should therefore as one SSD for the operating system as well as for the programs that are often used. The data, which are precious and require a lot of storage space, but by no means necessarily need a fast-working hard disk, can be stored on an external hard disk or second HDD. These include videos, photos and music files. Thus, data management can succeed in increasing the speed of the computer, but taking up no space on the SSD, which would be better utilized elsewhere.

interface
There is no huge choice of interfaces for an internal SSD. The most important are PCIe and SATA, with SATA being the lightest solution in the home. If a SATA interface is used, the definition as a boot disk is easy. PCIe solutions need a bit of setup experience to be integrated into the system as a main hard drive. These versions are therefore particularly interesting for professional users and system administrators. The used transmission protocol also influences the writing and reading speed.

Read-write speed
The current protocol, officially called SATA III, allows for a gross data rate of six gigabits per second, which is 750 megabytes per second. However, because some of the bandwidth is used for internal operations, the communication between the operating system and the hard disk controller, the actual data rate is at most 600 megabytes per second. In terms of enterprise solutions, one also speaks in part of even higher transmission rates. Many SSD hard drives reach about 500 megabytes per second, which makes it easy to work fast. However, modern devices differ only marginally in speed: the fastest-working SSD is about 20 megabytes per second faster than the corresponding average. You only notice that if you always want to move a few terabytes of data.

lifecycle
The life of the SSD depends on the built-in chips. SLC chips last longer than MLC chips. Also, the lifetime depends on how often new data is written to the hard disk. Even so, one should refrain from moving ever larger amounts of data to the computer containing an SSD hard drive.

additional features
Numerous manufacturers mention technical terms in the article descriptions of their SSD hard disks. Below are the most common names associated with this category of items.

TRIM
This term refers to the optimization of an operating procedure. Because you can not simply erase SSD hard disks, but only pass them block by block, the TRIM function causes all sections of the hard disk, which are marked as removed in the command times, to be deleted while idle. As a rule, this would happen just before the new description. TRIM helps save time, which is especially useful when the SSD hard disk is running low on free space.

SMART
This term stands for self-monitoring of the hardware so that possible failures can be predicted. This is done constantly monitoring the activities of the data memory. The results are stored on this.

Garbage collection
This refers to automatic memory optimization by never using used memory space. For SSDs, this operation is performed by the firmware, which is the hard disk control program. It serves to increase the writing speed.
