7 Best Internal SSD To Buy for PC or Laptop (Buying Guide 2021)

Best SSD For PC or Laptop – Top Suggestions

SSD’s are becoming extremely popular; Apple and several Windows laptop manufacturers use them in the laptops.

In fact, most new laptops use them to give speed and performance advantages.

Gamers and designers, even bloggers and professionals, are using them in the Desktop PC to make them boot faster and run complex software with speed and ease.

Below we will explore various aspects of Solid State Drives and why they are necessary for your PC/Laptop.

In this article, we will look at 4 major points that you must consider before buying an SSD.

What is an SSD?

SSD stands for Solid State drive, or also known as the Solid State Disk. It is a misnomer as it does not have any disk or drive.

The SSD unlike the HDD stores data on integrated circuits, the current generation of SSD’s store data on NAND  based flash memory, which retains all information without power.  SSD can be viewed as a larger Flash drive or pen drive which uses a similar NAND storage to store data permanently.

The SSD uses the traditional SATA interface to transfer data like the traditional HDD.

“In 1991, San Disk created a 20MB Solid State drive which was sold at $1000. (Rs. 60000).”

What is the Difference Between SSD and HDD? 

The fundamental difference regarding Hardware between SSD and HDD is that while Hard Drive uses actual disk and spindle to store data, SSD stores the data on NAND based memory chips and has an I/ O controller to manage the read/write operation.

Regarding performance SSD’s are much faster compared to typical 5200 RPM or 7200 RPM Hard Drives.

The Price for SSD is much higher for the same capacity say a 1TB hard drive will cost you Rs. 3800, while a 1 TB SSD will cost 30,000, roughly ten times the cost of HDD.

Here is a Table Comparing Some of The Major Differences between SSD and HDD

Parameter  Hard Disk Drive(HDD)  Solid State Drive (SSD) Remark
Cost for 1 TB Rs. 3000 Rs. 15,000 Approx. 5 Times the Cost of an HDD
Storage Capacity Upto 6TB or more Maximum 1TB or 2TB Much Larger for HDD
Popular Sizes 1 TB and 2 TB 256 GB and 512 GB Much Larger HDD
Read Write Speed 30 MBPS-100 MBPS 400 MBPS to 3000 MBPS Estimated Speed Vary with System Specs
Failure Rate 2.0 Million Hours 1.3-15 Million Hours Longer Life Span for SSD
Noise Higher Noise Lower Noise HDD has higher noise due to moving parts, SSD has no moving parts
File Opening Speed Slower on HDD 100% faster for SSD Files or Browser windows, large PDF  excel word docs
Windows Boot-Time 35 to 45 Seconds 10 to 20 Seconds Again Some dependency on other hardware, SSD is faster
Vibrations Vibrates due to spindle No Vibrations You can feel more while heavy data transfer or gaming
Heat Produced High Due to friction in moving parts Very Low SSD scores above HDD
Power Consumption higher Lower SSD scores above HDD
Magnetic Effect Impact Can Destroy data from strong Magnetic Effect Can’t destroy Data on SSD SSD is safer

Best Uses of SSD

  • You can use SSD to speed up your old Laptop.
  • SSD can be used in a desktop Gaming PC to speed game load time.
  • For Designers and Software users for 3D designing – Photoshop, Maya, and Video editing SSD is a blessing.

What Size of SSD Should You Buy for Laptop or PC?

It is more of personal preference and budget is a major criterion for deciding how much space you want on your SSD.

Ideally, I would prefer a 256 GB or 512 GB for a home/gaming PC since I also have 2 TB hard disk as well for keeping larger files like movies, games, etc. 

What I have on my SSD is programs like Photoshop, gimp, paint, Microsoft Office, Windows, and other basic software that I for day-to-day tasks. Also, outlook PST and downloads are on SSD.

The rest of the stuff like games, movies, music, and other data is stored on the 7200 RPM drive.

For Laptop’s I would prefer a 256 GB or 512 GB SSD, 128 will be low for a laptop as you don’t have any other HDD in which you can store files for quick access. Better to go for a 256 GB or 512 GB SSD. You can use a USB 3.0 expansion drive with the laptop, but again you will have to carry it all the time.

What are Different Types of SSD’s?

1. SATA (Serial Advanced Technology attachment)

SATA SSD is a storage device that can be connected with a data cable and a power cable directly into the motherboard and the solid-state drive.

SATA-based SSD’s can have a speed in the range of 500 to 600 Mbps which is not very fast but it is more than sufficient for most use cases and workloads. It is even sufficient for image editing and video editing when using the Adobe Premiere Pro. 

2. NVMe (Non-Volatile Memory express)

The NVMe allows its solid-state drive to study the data exact from the PCIe slot undeviatingly from the motherboard.

The NVMe SSDs can have a much higher data transfer (Read and Write Speed) in comparison to the SATA based SSDs. The NVMe SSDs can go up to 3000 Mbps in reading/write speeds and typically offer between 1000 to 2000 Mbps. 

You should check your laptop or PC motherboard to understand the type of SSD it supports and then make the purchase decison. 

Adding SSD to PC or Laptop?

In most laptops, you will have to take out your normal Hard drive which is usually 2.5 inches in size, and can replace the Drive with SSD.  You can buy a laptop USB cover and connector to use as a backup drive.

For Gaming PC it is fairly easy to add an SSD, you can either clone your Windows on the SSD drive and remove the windows from HDD. I will suggest copying everything on your boot partition say C drive to D drive.

Then install the Windows 10 OS on the SSD fresh. SSD for laptop or PC are the same size; you can use it on either PC or Laptop or even swap between your devices.

Also, some of the new MacBooks and Windows laptops come with soldered SSD that are not replaceable.

For a Gaming PC you can always buy the standard 2.5 inch SSD.

I have had problems in cloning from HDD and SSD, while some people say it just worked fine for them. In my opinion, to be safe and avoid any issues, you can do it once.

I will share in the next article – How to Add an SSD to a Gaming PC and do a Fresh Install of Windows. The second article we will share is a 7200 RPM Drive VS SSD speed performance Test. (likely in next week).

Now we are done with the basics, lets see which is the Best SSD you can buy for your PC or Laptop. 

7 Best SSD to Buy for PC or Laptop

We are referring to and comparing the 128 GB versions of SSD here; you can also opt for the same brands in 256 or 512 GB sizes as well.

Do different brands have a speed/performance difference in SSD? Yes different brands and internal hardware, NAND chips and controller makes a difference in the speed of SSD. Also, note the higher capacity SSD is slightly faster compared to low storage capacity SSD.
