RAM Memory

RAM Memory is very important and one of the basic computer components. This is the place where the computer temporarily stores the individual data. The more memory you install on your computer, the more programs will be able to run at the same time, which will run more efficiently. RAM is important for the performance of your computer. Of course, in the context of memory has not only its size, but also the operating parameters.

What are the types of memory?

There are several types of memory, but now they are the most important:

• DDR 3
• DDR 4

What kind of memory you can install on your computer, it will depend on the motherboard. Since it also depends on the amount of memory that is how many GB can handle up to and how capacious may be a single unit.

The main differences between DDR3 and DDR4:

The most important thing that is decisive for the choice of a given standard is not the parameters of individual versions of RAM, but rather the purchase of a motherboard - more precisely the processor. If it is a unit belonging to the Haswell-E family (as for now) and the X99 chipset, the user is condemned to DDR4 memory. Otherwise, he has to buy DDR3 dice. Installation of a specific version of RAM is forced by their different construction, and there is no possibility of inserting them into the same slot.

The theoretical differences between DDR4 and DDR3 memory are included in the table below:

DDR4 bone structure is different from its predecessor. The module is a millimeter higher, and thanks to the same width, the pins are more densely spaced. The position of the indentation has also changed, avoiding mistakes when inserting the bone into the wrong slot. It is also worth remembering that the DDR4 module is not backwards compatible.

SSD

SSD (solid-state drive), sometimes also a solid state disk - a mass storage device based on flash memory. The basic advantage of SSD is the lack of moving parts. In addition, these disks are characterized by significantly shorter data access time (several dozen times), quieter operation and much more resistant to mechanical damage (caused, for example, by shocks during work or fall from a height). Another issue is the use of SSD memory in industrial computers, where large capacity is not important as it is in the case of classic HDDs, but above all operational reliability and resistance to vibrations. SSD memories in industrial applications do not require capacities of 50-100 GB, because in practice capacities of 512 MB-8 GB are used, and it is enough to keep memory at a relatively low cost.

The advantages and disadvantages of SSD

The biggest disadvantage of SSDs is their price to capacity. HDD disks are more widely available, have a larger capacity and are cheaper. However, as disks with moving mechanical systems have some disadvantages that SSDs do not have.

The advantages of SSDs:

•      less energy consumption - there is no need to drive magnetic discs like in HDD disks,
  
•      minimized failure rate,
  
•      instant data writing and reading - programs, games, system start without delays,
  
•      higher bandwidth - faster data transfer,
  
•      resistance to shocks - the disk with moving mechanical parts may be damaged due to a fall, interrupted by writing or reading data,
  
•      in the event of a sudden power outage, the data stored on the flash memory will not be erased,
  
•      work in a larger temperature range than HDD disks,
  
•      they emit less heat,
  
•      no need to defragment the disk.

Limited lifespan of the SSD

The disadvantages of SSDs are their limited lifespan due to the limited number of data write cycles. There is a type of memory associated with the life of the disk:

•  SLC (Single Level Cell) - 1 cell records 1 data bit,
  
•  MLC (Multi Level Cell) - 1 cell saves 2 bits of data,
  
•  TLC (Triple Level Cell) 1 cell saves 3 bits of data.

HDD disk

HDD (Hard disk drive) - the type of storage that uses magnetic media for data storage. Disk HDD type consists of a plate or disc assembly for aluminum alloy coated with a thin layer of magnetic media and electromagnetic heads that allow reading and writing of data. For each disk platter accounts for a pair of heads - one head and one read-write. The data are stored on the disk platter by sending electromagnetic flux through the recording head. Hard drives are the most important the following parameters: capacity, data rate, data access time, speed magnetic disks (rev / min.) And the mean time between failures (MTBF).
