Best SSD M.2 NVMe and PCIe. Which is the Best SSD for Desktop and Laptop?

There are in modern tech time a common question is Which is the Best SSD for Desktop and Laptop? Best SSD M.2 NVMe and PCIe. Not all SSDs (Solid state drives) are the same. There are some main key elements that determine compatibility, durability, speed, performance, and price. In this article we explain the M.2 form factor, the differences between PCIe vs. SATA and what exactly NVMe means. With this information, you will make more informed decisions about which Solid state drive (SSD) right for your device.

Which is the Best SSD M.2 NVMe vs M.2 SATA 3 PCIe?

SSD is the involution of Memory technology. If you want to high speed ROM system in your laptop and desktop there are no option without SSD. Because HDD was disk system and it was moving parts which speed depend on disk RPM. But now a days new designed SSD that’s means Solid State Disk. Where no any moving parts. It’s like a SD or MicroSD card type Solid Conductor and semi conductor type.

  • Now common question is which SSD is better because SSD and motherboards now multiple variants.
  • Some motherboards support PCIe 3, PCIe4
  • And news generation Motherboards support NVMe type
  • This PCIe and NVMe both have different speed and size of memory reading and writing speed.
  • M.2 slot is not matter but M.2 slot need to support NVMe then you will get highly performance from your SSD. If your SSD also supportable NVMe.

What is M.2?

M.2 is a form factor specification that was introduced in 2012 and designed to replace the mSATA standard. The form factor specification spells out the physical size and shape of the SSD card you can connect to your system. The M.2 form factor is designed to maximize PCB (printed circuit board) while minimizing the amount of space it takes up in your PC or laptop. To connect an M.2 specified SSD, your motherboard will need to have an M.2 slot.

The M.2 form factor is small and rectangular in shape, almost like a piece of gum. Sizes can vary, with possible widths of 12, 16, 22, or 30 millimeters, but they are generally 22 millimeters wide. Lengths can also vary, coming in 16, 26, 30, 38, 42, 60, 80, or 110 millimeters. Motherboards will accommodate a variety of lengths for an M.2 module to allow for flexibility, while the width is more fixed.

SATA vs PCIe interfaces

Now we know that the M.2 form factor dictates what type of memory drive we can connect. Our next job is to understand SSD interfaces.

In general PC building terms an interface connects two or more separate components to exchange data or information. The SATA and PCIe interfaces are the physical connections that transmit data from the memory storage to the computer.

SATA and PCIe aren’t the only available interfaces for SSDs, although they are now the most common.

What is SATA?

The older of the two interfaces, SATA was launched in 2003, bringing massive advancements to computing and memory storage. In the image below, you can see how a SATA interface connects to your motherboard. The original SATA interface was designed for hard drives, but when SSDs came on the market, they adopted the same interface so users could easily upgrade their storage drives.

What is PCIe?

PCIe (Peripheral Component Interconnect Express) is a newer interface that features a smaller physical footprint, meaning it takes up less space in your computer, as seen in the image below. The real advantage of the PCIe interface over SATA is the ability to transmit data on up to four lanes, whereas SATA only has one. When combined with an NVMe SSD, which we’ll discuss shortly, PCIe SSD read/write speeds increase even more than SATA.

PCIe vs SATA

The implementation of multiple lanes for the PCIe connection is one of the most essential features. PCIe uses four lanes for storage devices, resulting in data exchange that is four times faster than a SATA connection, which only has one lane.

All of these enhancements come with another benefit: reduced power consumption. The combination of NVME, PCIe and an SSD’s lack of moving parts results in a quieter storage drive that sips power, extending battery life for laptops, notebooks, and tablets.

What is NVMe?

  • We know that if you have a SATA interface, you will need to connect a SATA SSD if you are looking to upgrade your memory, but what if you have PCIe?
  • NVMe (NVM Express™, or Non-Volatile Memory Express) is a communication protocol designed specifically to work with flash memory using the PCIe interface. NVMe was created to take advantage of the parallel nature of solid state drives.
  • NVMe SSDs combined with a PCIe interface create unrivaled read and write speeds. However, you can also get PCIe compatible SSDs that are non-NVMe.

NVMe performance

Combining the NVMe SSD and the PCIe connection results in read and write speeds that are four times faster than a SATA interface/SSD.

NVMe complements the parallel structure of contemporary CPUs, platforms, and applications. These parallel structures allow for more commands to flow simultaneously. NVMe uses an optimized path to issue commands and complete input/output, and it supports parallel operation with up to 64,000 commands within a single I/O queue and 64,000 possible queues. Older protocols such as SCSI are serial in nature, with a limited number of commands in a single queue.

When it comes to the best SSD for desktop and laptop, it really depends on your specific needs and budget. Here are a few of the best SSD options available in the market:

  • Samsung 970 EVO Plus: This is a popular NVMe SSD that delivers fast read and write speeds and high endurance.
  • WD Blue SN550: This is a budget-friendly NVMe SSD that offers good performance and value for money.
  • Crucial P5: This is another NVMe SSD that delivers fast read and write speeds and comes with a 5-year warranty.
  • Kingston A2000: This is a budget-friendly NVMe SSD that provides good performance and reliability.
  • Seagate FireCuda 520: This is a high-performance NVMe SSD that delivers fast read and write speeds and has a large capacity.
  • In terms of PCI-e SSDs, the Samsung 970 Pro and the Intel Optane 905P are two of the best options available in the market.

It’s important to consider the compatibility of the SSD with your laptop or desktop before making a purchase, as well as your storage needs and budget. You should also look at the warranty and customer support offered by the manufacturer.

Compatibility with your PC  is the most important factor in choosing an SSD interface. It can be challenging to tell the difference between PCIe and SATA connections if you look at the slot on the motherboard. Check your computer specifications to see which interface your computer supports.
