The goal is to increase performance, efficiency, reliability, and lower overall operating expenses (OpEx).

When it comes to market growth, it is likely to increase from 26.5 billion in 2018 to USD 60.2 million by 2023, at a Compound Annual Growth Rate (CAGR) of 14.7% ( trend analysis report by

To begin to understand the usage of SSD, why is SSD preferred? Are SDD and SSD the same?  What exactly is SSD? let’s dive in.

What Are Enterprise Solid State Drives?

The hard drives which we were using earlier consisted of mechanical parts like a read/write head to gather data. These components had a limited life and could fail with due course of usage.

However, a solid-state drive (SSD) is a new generation of storage devices that have flash-based memory. It is much faster and reliable with a better life. One of the significant uses of SSDs is their speedy operation due to low read-access times and fast throughputs.

A simple NAND chip is used in the memory chip that has no moving part. The use of these devices started in the 1980s but was limited to supercomputers. In the early 1990s, many devices were having SSDs as the prices dropped but the limited size and life span were still the main issues for the restricted use.

In the late 2000, solid state drives became a part of PCs and laptops of high configuration and it became a part of an acceptable option after 2015.

Today, it has become a choice of the Pc and laptop buyers as it offers many advantages in areas like business, gaming, mobility, and servers. Even for new laptops and PCs, it has become a default choice.

To attach an SSD to your system, you need to connect it using a specific interface. Common interfaces are:

  • PCIe and NVMe SSDs: PCI Express (PCIe) – to connect graphics cards, network cards, or other high-performance peripherals.
  •  mSATA III, SATA III, and traditional SSDs: Serial Advanced Technology Attachment (SATA) – good to replace HDD, even an upgrade to a SATA-based SSD is good for old PCs and laptops for normal use.

How Is Solid State Drives Better Than SATA and SAS?

SAS vs SSD performance chartTo get a more comprehensive view of why it makes sense to get an SSD over an HDD, let’s view some of the factors that create a difference:

Performance – SSDs can deliver incredibly high read and write performance for both sequential and random data requests from the CPU. With no degradation of the response time, the NAND flash drives have low latencies, which increases user productivity.

SSDs are optimized not only for peak performance in the first few seconds of access but using a larger over-provisioned area (OP). A higher sustained steady-state performance over longer periods increases its adaptability for laptops and PCs.

Reliability – During the production process of each Flash drive, a die-cut from silicon wafers is tested and characterized with a Raw Bit Error Rate (BER or RBER). The BER defines the rate at which naturally occurring bit errors occur. The SSD Controller corrects ECC  (error-correcting code)) without disrupting user or system access.

The SSD controller’s ability to correct these bit errors increases the reliability of the drive thus passing the JEDEC credibility tests.

Power Fail Protection – The SSD architecture has frequent flushing of data from the controller’s cache areas. This reduces and minimizes the data loss during a power failure. Drive’s Power Fail Protection also ensures that the SSD is not likely to become inoperable after encountering an unsafe shutdown. For web-scale data centers, solid-state drives are a great benefit.

Compatibility – An enterprise-class SSD can withstand heavy read or write activity like downloading a video or audio file from the internet on a PC or laptop. Enterprise SSDs have a 24×7 duty cycle with a 20/80 duty cycle (20% of the time active, 80% in idle or sleep mode during computer usage).

The high TeraBytes Written (TBW) value of SSD makes it compatible with other devices used for storage like RAM. An endurance metric can be calculated to check the performance of SSD.
