How much do you rely on storage spaces, either physical or digital?

Storing things in a safe place is coded into our brains because of our ancestors’ lifestyle. They constantly had to search for food or living supplies, and once they found it, they would tie it up in a tree or hide it in a cave to keep them safe from animals.

Flash forward to today; not only do we need to store our physical belongings, but we also need safe storage space for our online data.

Companies use servers or data centers to store their data, but they can opt for SSD servers if they want to access and process this data faster. Besides, a storage device should withstand different types of damage, which is what we can count on with an SSD server.

Since both SSD servers and HDDs are quite popular among users, we will talk about each of them in detail and then give you helpful tips to decide which suits you best.

Let’s begin.

What is an HDD Server?

An HDD server is a server that has a data storage device called HDD (Hard Disk Drive). HDD is a physical storage device that has four primary parts:

  • The Spindle Motor: In charge of rotating the disks.
  • Magnetic Disk Platter: In charge of storing data.
  • Actuator Arm: In charge of moving and controlling the read/write head.
  • Read/Write Head: In charge of reading disks by transforming the platter’s magnetic field into an electrical current and writing disks by transforming an electrical current into a magnetic field.

(Imagine a turntable record player for better understanding.)

The primary purpose of an HDD server is to write and read data; the read/write head moves over the spinning disk platter and uses electromagnetism to complete this process. Since the process is mechanical, too much power consumption and noisy and slow operations are unavoidable.

Even though a single HDD server offers a lot of storage space _up to 4 TB_ , it is quite fast (the platters spin up to 7200 times per minute) and can store data even in sudden shutdowns. They are, however, vulnerable to physical damages, such as drops, heat, vibration, etc.

What is an SSD Server?

Think of an SSD server as a non-mechanical storage device powered by the main processor chip. SSD (Solid-state Storage Drive) consists of NAND flash memories that are non-volatile data storage.

Most of our digital devices, like smartphones, have NAND flash memory which is made up of tiny memory cells integrated into transistors and doesn’t need a power supply to function. The controller chip in an SSD server is in charge of transferring data from the flash memories to the input-output ports.

Some SSD servers have another type of flash memory called DRAM (Dynamic Random Access Memory), which tracks data across the SSD server (This process is similar to cache memory). So if you use an SSD server with a DRAM, you can access the flash memories’ data much faster.

Since an SSD server relies on integrated circuits instead of spinning disks to store data, it’s much more durable against physical damage and even withstands high temperatures, unlike HDD servers.

From an enterprise-friendly point of view, SSD servers are the best choice for storing data.

Here are some concepts and acronyms related to SSD servers you might have encountered or will encounter when you start shopping for one:

  • Serial Advanced Technology Attachment (SATA): In charge of reading and writing data to and from data storage.
  • Serial Attached SCSI (SAS): In charge of connecting the storage device to the host computers.
  • Non-Volatile Memory Express (NVMe): In charge of executing fast data transferring protocols.
  • SLC (Single-level Cell): A NAND flash memory that stores one bit of data per memory cell.
  • TLC (Triple-level Cell): A NAND flash memory that stores three bits of data per memory cell.
  • MLC (Multi-level Cell): A NAND flash memory that stores more than one bit of data per memory cell.

HDD vs SSD Server; Form Factors

HDD or SSD form factor refers to internal components’ size, shape, and physical arrangement.

Here are different SSD form factors:

  • 2.5 Inch SSD: 2.5 Inch (standard-sized) SSD used in personal computers.
  • mSATA SSD: One-eighth the size of a 2.5 Inch SSD, primarily used in mini gadgets.
  • M.2 SSD: 22 mm wide and 80 mm long, mostly used in PCs designed for gaming, 3D animation, and video editing.

Here are different HDD (IDE (Integrated Drive Electronics) or SATA hard drives) form factors:

  • 3.5 Inch: Mostly used in desktop disks.
  • 2.5 Inch: Mostly used in laptop hard drives.

HDD vs SSD Server; Which One Do I Need?

Most businesses that handle and store heavy data loads use SSD servers.  Since SSD is faster and more lightweight than HDDs, they are considerably more expensive. So if you have a home-based small business and can place your storage device in a safe place away from harm, an HDD server is the more cost-effective option.

However, in the case of mechanical failure, you might have no choice but to repair the damaged parts or have them replaced, which might cost you a lot. Also, an HDD server consumes heavy loads of power, so don’t be shocked when you see your electricity bill.

The good news is that some suppliers implant shock sensors into HDD servers; they can detect system failure and shut down the HDD before critical damage occurs.

On the other hand, an SSD server is the best option for major corporations because it offers low latency and can support heavy workloads without sacrificing speed. An SSD server is a high-performance storage device built to write and read data in real time. Also, if you’re in the business of developing virtual environments, SSD servers are the optimal choice to optimize and balance storage performance.

Virtualization technology relies on the host server’s resources to operate correctly; each server is divided into virtual compartments, which act as a virtual power source for the virtual environment.

So by using an SSD server, you can build a virtual environment that perfectly copes with the high I/O demand of the guest operating system.

Should I use an HDD or SSD for my server?

It depends on your workload and budget. If you process a considerable amount of data on a daily basis, then an SSD server is the most durable and fastest option. But both features come at a price. HDD servers are cheaper but require meticulous care because they are made of mechanical parts which are prone to physical damage, such as heat, falls, etc.

Which one is faster, HDD or SSD?

SSD servers are faster than HDD servers because they have no physical parts and read and write data through electrical circuitry.

Are SSD servers cheaper than HDD servers?

No. SSD servers are more expensive than HDD servers because they operate on new storage technology, which results in faster data transfers and optimized performance.

What is the best SSD for server?

It depends on the type of server and how much storage capacity you need. For example, the best SSD for an NVMe server is WD Gold SN600. The best SSD for server should support fast data transmission and withstand heat fluctuations or sudden shutdowns.

HDD Vs SSD Server; What is their pricing range?

The cost of HDD or SSD servers depends on the capacity of the storage drive, its form factor, and the warranty it offers. Here are some examples of HDD and SSD pricing:

HDD, 3.5 Inch, 5 years warranty, 4 TB: $67

SATA HDD, 3.5 Inch, no warranty, 4 TB: $53.99

Used SSD, 3 years warranty, 480 GB: $26.87

Instead of paying hefty fees for either a used or new SSD, you can purchase our fast and ultra-safe SSD VPS at $9.95 a month.
