Best internal Sata and NVME SSDs for Laptop 2021

Internal Solid State Drives (SSDs) are a new and emerging technology in the storage market. They offer significant advantages over traditional hard drives, such as faster read/write speeds, lower power consumption, and more durable flash memory chips that can withstand shocks from drops or impacts.

The best SSDs for laptops or PCs are those with a capacity of 256GB-512GB, which is enough to store around 100 hours of HD video content. There’s no need to worry about running out of space any time soon! However, if you want even more room than that, consider getting an external hard drive instead.

Fastest internal SSDs

If you’re looking for an internal SSD for a laptop, here are the top 5 best on the market. If you’re planning to buy one, make sure that it meets your needs in terms of size and speed.

Crucial SSD

The first one is from Crucial and it’s a SATA III 6GB/s 2.5 inch Internal SSD with reading speeds up to 550MB/s and writes speeds up to 500MB/s.

It has a capacity of 120GB, but if that isn’t enough space for your needs they also have 240GB and 480 GB options available so there should be something for everyone here.

Crucial MX500 1TB

  • High Capacity SSD
  • Reliable and cheap

The Crucial MX500 SSD comes with a 3-year limited warranty and features blazing fast speeds, improved endurance, and power efficiency. It is compatible with the latest motherboards using the new NVMe protocol.


  • Really fast loading speed and on the edge performance.
  • built-in DRAM
  • Crucial support is excellent.
  • installation is simple with no frills


  • The software interface is not user-friendly.
  • Installation cost another $40 for the Acronis software

Crucial SSD. With fast access to your media, creations, and designs, you’re ready to share at the speed of life. The solid-state drives should be a tool for productivity and creativity – not just another component to upgrade or replace when technology marches forward. And so this SSD is designed as an entire line-up of mainstream consumer storage solutions built from the ground up with leading-edge technology.

Intel SSD 520 Series

Next, we have an Intel 520 Series SSDSC2CW240A3K5 which can hold 180 gigabytes of data.

The Intel® Solid-State Drive Data Center Family for PCIe delivers the performance, reliability, and capacity to meet demanding enterprise storage requirements—without compromising on price.

intel 520 series SSD

  • Series: 520 Series Cherryville
  • Device Type: Internal Solid State Drive
  • Capacity: 180GB
  • Memory Components: MLC
  • Interface: SATA III
  • Form Factor: 2.5″

The Intel 520 Series represents an update of the SS line, which has traditionally offered high reliability for a decent price. I bought this in the 240GB version to upgrade my older 2nd generation core i3 CPU and believe it or not my system speed is now 10x faster than before. I am impressed with the results coz it is not expensive but faster than a traditional SSD.


  • A huge leap forward in speed
  • Intel SSD Toolbox software to measure SSD health.
  • Software Transfer cloning an old drive easier


  • less reliability than previous Intel drives.
  • about .8 watts instead of .6
  • other better options are available in this price range.

This is SSD made my machine even snappier. Disk-bound tasks are done in a flash; file transfers that once took minutes now take seconds.


If you are looking for an upgrade to improve performance on your PC, there are some things to keep in mind when purchasing an SSD. The first thing to consider is how much storage space you need – 128GB should be enough for most people but if you have a lot of data or want to store games or other large files then 256 GB may be better. Storage size aside, WD drives are typically considered the best quality because they use 3D NAND technology which provides higher reliability and longer life expectancy than traditional 2D N.

Here comes the WD Blue NVME SSD in the ground.

Western Digital 1TB WD Blue
  • Up to 2,600 MB/s
  • Up to 1,800 MB/s

Western Digital’s next-gen NVMe SSDs are over four times faster than their SATA counterparts. The Western Digital designed controller and firmware ensures that the performance is optimized.

Their new, innovative SSD dashboard constantly monitors your drive for you so that there will be no surprises when it fails unexpectedly at a crucial moment! Though these drives aren’t compatible with our older motherboards which use SATA technology, they’re well worth investing in to ensure your data stays safe from corruption or loss due to unexpected hardware failures.

Western Digital has launched its latest nvme SSD range offering speeds up 4x higher than traditional 2d based hard disks. These devices offer much lower power consumption rates.


  • The SSD is an excellent price,
  • Provides great performance at 2400 MB/s read (the PCIe interface can reach up to 8 Gb/s).
  • The software monitor measures the health of the SSD.
  • 4x Faster than traditional SATA SSD.
  • Designed for optimized performance


  • Although the performance of this 1TB WD Blue SSD was not as fast my existing 256GB drive or Samsung’s Evo line, it costs more than similar capacity SATA HDDs.
  • Not Compatible with traditional SATA interface.


Samsung’s new 980 PRO PCIe 4.0 NVMe SSD is a next-level upgrade to the company’s previous generation of high-speed solid-state drives, delivering read speeds up to seven thousand megabytes per second for gamers and tech-savvy users looking for maximum performance from their hardware.

Designed with hardcore gamers in mind, this drive features higher bandwidth capabilities than its predecessors while still maintaining all the reliability you’ve come to expect from Samsung!
