If we go back in the early 1940s the first generation of computers was constructed on pillars of vacuum tubes. We had these long self-tangled vacuum tubes to perform basic and complex mathematical computation. Moreover, it can be observed that some of the first generation computers were as big as the size of a bedroom or a series of bedrooms. Hence it is conclusive that the first generation computers had a mechanical design. But the present generation – that is, the fifth generation of computers has evolved quite progressively and efficiently. Some of the major changes in the process of evolution are “Laptops”, “External HDs”, “Microprocessors”, etc.

The present generation of computers are also becoming increasingly dependent on SSDs – Solid State Drives. Solid State Drives are a rather popular alternative to the conventional Hard Disk Drives that are increasingly being phased out. Although SSDs are a far better option for various reasons (SSDs bring in a significant change in your machine’s performance) – they haven’t been widely adopted owing to their high cost compared to an HDD. Let’s dive in and know more about how SSDs work. Cashify brings to you an insight on Solid State Drives.

Hardware

SSDs go very much by their name, i.e. their entire structure is stationary or solid in nature. The conventional electro-mechanical HDDs(Hard Disk Drives) can be distinguished from the SSDs in many aspects. Some of them being:

  • SSDs have no moving mechanical parts.
  • SSDs do not produce noise while fetching or storing data.
  • Most importantly SSDs have higher data transfer rate and cache.

Additionally, SSDs are compact in design and have this very useful feature of retaining data without power. This can be achieved with the help of NAND-based flash memory. In spite the fact that the idea of SSD can be traced back to the early 1950s, but their practical application and a real-time model was not designed until the late 1980s. Thus it is obvious that the smooth performance of your laptop can be attributed to SSDs.

Technicality and Software

Without going in too much detail, let’s look at the major aspects responsible for the elevated performance that a SSD provides.

    • First of all, peeping into the type of memory SSDs use: Most SSDs are found to be functional with “Dynamic Random Access Memory- DRAM”, this contributes to about 50% in increasing the performance of your laptop or your device. DRAM is specialized for ultrafast data access and data storage, general statistics have proven that data access takes place at the rate of 20 microseconds.
    • Secondly, you might be familiar with the terminology of ‘cache and buffer’. Cache is a small part of the memory, where the most frequently used applications and programs are stored. This reduces the workload on the architecture of the Computer. It is easy to read instructions from the cache, rather than recall it from computer’s memory. Henceforth, the memory allotted to cache is considerably less i.e. in general cases is varies from 3MB-12MB. Due to ultrafast access in SSDs Cache and Buffer prove out to extremely contributing in speeding up your laptop. In spite of having an ultrafast DRAM, a small part of the DRAM is dedicated to the Cache which improvises your laptop’s performance.
    • Finally, the host interface is the part which calculates and manages the transfer rate. There are different interfaces, some of the common examples are:
      1. Serial attached SCSI – SAS (generally found on servers, Transfer>3.0 Gbit/s)
      2. Serial ATA – SATA (>1.5 Gbit/s)
      3. PCI Express – (>2.0 Gbit/s)

      These interfaces are even supported by HDDs, so there is no issue raised when data is transferred between a HDD and SSD. The newer versions of SSDs produced by Intel are capable of transferring the data at the rate of 6 Gbit/s.

Some of the commonly experienced advantages of SSD are: quicker reboot, faster data and instruction transferred,and smoother multi-functionality.

Clearly, SSDs are more than capable of boosting up storage performance multiple times over. If only we could keep aside the cost issues, SSDs would have our full support.
