The Solid State Drive (SSD) performance plays a major role over pricing and storage . The prices of SSD have been slashed so less. You can get a 250GB SSD storage capacity for $60. 

In the SSD vs HDD battle, reads and writes play a major role. Traditional spinning is eliminated using Solid State Drives. 

Storage Space, Battery Life, Transfer Speeds of 120GB SSD are fast enough for Windows 10. HDD Storage is useful for users with requirement of huge requirement for photos, videos and editing.

SSD Technology and Conditions

Install the Windows 10 OS on your 120GB SSD and use HDD for storage.  Replace your old disk with an SSD. Even with old laptops and notebooks with 2GB RAM, the speed boost can be seen.

Then using a casing, you can make your internal HDD into an external drive. Otherwise, remove your old CD/DVD and keep both drives.

In the SSD vs HDD boot time comparison, SSD wins the battle by a large margin. You can boot your computer in seconds with SSD compared to minutes of HDD.

Windows 10 is notorious for its updates. Each change will add an overhead which will slow your PC and boot times.

Which is a better option for your PC or Laptop? How to select between SSD and HDD? Now, you come to know the differences. In this post you are going to find answers to ssd vs hdd speed and my personal experience with benchmarks, boot time and gains. 

SSD vs HDD – What are They

According to Wikipedia, these are the definitions of HDD and SSD –

A hard disk drive (HDD) is a data storage device used for storing and retrieving digital information using rapidly rotating disks (platters) coated with magnetic material. An HDD retains its data even when powered off. Data is read in a random-access manner.

A solid-state drive (SSD) (also known as a solid-state disk or electronic disk, though it contains no actual disk) is a data storage device using integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives.

How to Choose

The best way to decide between traditional hard drive and solid-state-drive on your desktop or laptop is the form factor and speed. Are you interested in storage cheap and plentiful, or fast and shockproof?

SSDs come with dynamic and static cache. As the storage gets filled up the amount of both gets reduced. For example, a 120GB drive will have only 15 to 30GB write cache left when it’s 80% full of data. You will get only 5 -6GB of dynamic cache and 1 to 3GB of static cache.

Many of the earlier solid-state-drives used to come with SATA interfaces. Now, many of the internal SSDs using NVMe, M.2 and quicker PCI Express interfaces.

HDDs have huge storage advantage with cheap price. But the read/write speed is slow and maintenance of these disk drives is troublesome. Disk fragmentation also has to be taken care of in Windows 7 and older systems.

If you are a gaming freak, then SSD write speed does not make any difference. When latest PC games perform random reads it will be big size of blocks. Performance tests will only indicate the SSD random IO ratings on 4kB blocks.

Why I prefer SSD over HDD

The Western Digital WDS240G2G0A 240GB SATA III 6GB/s 2.5 7mm Internal SSD (Green) was bought in July 2019. It improved my boot time and operational speed of my computer. It is so easy to install and less chances of getting crashed.

The SSD vs HDD benchmark comparison lies in the parameters you compare. If you compare pricing, HDD is the clear winner. You get cheaper price per GB in HDD. A Seagate Backup Plus Slim 1 TB External Hard Drive Portable HDD can be had for less than $60.

But if you compare faster boot speed and performance, SSD will out-smart the “older” platter drives.


The HDD history is little old, starting from the infamous IBM 350 RAMAC hard drive to the today’s SATA connected 2.5-inch notebook-class drives.

Disk Storage

The amount of disk space also has increased from 40 GB to 2 TB  for desktops and laptops. There are even 6 TB HDD which are used for video storage and multi-media processing.

Memory Technology

The SSD which has its roots, way back in 1970s, with the invention of bubble memory flashing etc. The present day flash memory is the logical extension of the same old idea. The SSD history started with the notebooks in 2000s.

This got extended in 2007, with the the OLPC XO-1 using a 1GB SSD, and the Asus Eee PC 700 series using a 2GB SSD as primary storage.

Pros and Cons of SSD vs HDD

Both these drives do the same functionality like boot your system, store your applications, and store your personal files. So we need to answer the differences which makes a user buy a particular drive.

There are different factors like price, maximum and common capacity, speed, fragmentation, durability, availability, form factors and noise.


For a 1TB drive, you are going to pay $75 for a HDD while the same is $600 for a SSD.

Disk Storage

The common available disk spaces in SSDs are 128 GB to 500 GB, while it maximum outs at 1 TB. Coming to an HDD, the common base system for a typical desktop configuration is 250 GB or 500 GB.

You can even get a 4TB or 6TB hard drive for the more personal stuff like music, videos, photos etc.

Boot Time

Coming to boot times, the SSD is lot faster than its predecessor. It boots up in 6 to 7 seconds, while the HDD has to wait 1 to 2 min, even with the latest processor and RAM.

Large and Small Files

The advantage with SSDs is that it doesn’t care where the data is stored on its memory chips. Unlike it, the HDDs, are good for large files, which are laid down on the magnetic coating in contiguous blocks.

But due to its methodology, the file system can be fragmented, for which you need to use de-fragmentation tools.


An SSD has no moving parts, so its suitable to carry in laptop bags and for office work. Even if you drop it, much damage is not done. But most HDDs park their read/write heads when the system is off and consist of movable parts.


The availability of HDDs comes from different manufacturers like Western Digital, Toshiba, Seagate, Samsung, and Hitachi, and the list is never ending with different models.

But SSDs manufacturers are new to the games and are still improving. 

Form Factor

Because HDDs rely on spinning platters, there is a restriction on the form factor. But SSDs have no such restriction which are currently available in the 2.5-inch laptop drive-sized boxes, but as the growth of tablets increase, the SSDs size can still decrease.

Due to drive spinning etc, the HDDs even if its the best, still emits some noise. Also faster HDDs make more noise than the slower ones. But SSDs make no noise at all, as they are non-mechanical.

Which one to Buy – SSD vs HDD

So if you are a multimedia user and heavy downloaders of torrents etc, wanting to buy a drive in your budget for $500 PC, video and photo editors and are keen on replacing a cheap drive, general user doing office work like Word, Excel, Powerpoint, Access, you just need HDDs. 

But people who are rough and want extra security to their drive, speed is the key coming to opening of Photoshop kind of applications or booting up, and don’t want scratchy sound coming from the drive, SSDs is your choice.


According to benchmark tests conducted by PCWorld, it ran an

Notebook WorldBench 8.1 benchmark suite on a recent-vintage Toshiba Satellite P75-A7200 laptop powered by a fourth-generation mobile Core i7-4700MQ CPU (part of the processor family code-named Haswell), and our Desktop WorldBench 8.1 suite on an older Maingear tower PC equipped with a second-generation Core i7-2600K (Sandy Bridge). Our colleagues at Macworld helped us out by running SpeedMark on an Apple MacBook Pro with a third-generation Core i5-3210M (Ivy Bridge). All three test suites measure the performance of the entire system—not just its storage subsystem.

In almost all the cases, SSD upgrades delivered huge performance gains.

So at the end, HDDs win on price, capacity and availability.

  • SSDs work best if speed, ruggedness, form factor, noise, or fragmentation (technically part of speed) are important factors to you.
  • I personally felt using HDD drive on Windows 10 computer doesn’t fully optimize the boot speeds.
  • It almost takes 2 minutes for my 64 bit OS to boot up after restart.
  • But using the new WDS240G2G0A SSD I could boot up in less than 15secs

With increasing emphasis laid on speed and cloud storage taking financial burden on an annual basis, the local drive space is going to stay.

My recommendation is to use SSD for Windows 10 OS partition.

This will improve the performance of your apps, games and boot time.

HDD can be used as a storage device for storing large video, office, multimedia files. This is like the hybrid-storage.

So in the coming few years if you want to do more work productively, I recommend going for an SSD even for a smaller size like 250 GB.
