Advantages of M.2 SSD | Disadvantages of M.2 SSD

This page covers advantages and disadvantages of M.2 SSD and its basics. It mentions benefits or advantages of M.2 SSD and drawbacks or disadvantages of M.2 SSD.

What is M.2 ?

M.2 is the form factor which indicates size and shape of the solid state drives such as SATA and SSD. M.2 SSD requires M.2 connector slot to interface. It does not require cables. M.2 uses SATA or PCIe or NVMe interface protocols to transfer data.

M.2 SSD Form Factors

It has to be noted that M.2 drive defines physical form factor and it is not protocol like SATA or NVMe. Refer advantages and disadvantages of SSD.

Benefits or advantages of M.2 SSD

Following are the benefits or advantages of M.2 SSD:
➨M.2 is a slimmer form factor for storage devices which is used along with either NVMe or SATA.
➨M.2 SSD offers cleaner and cluttered PC interior environment with fewer cables. This allows better airflow inside.
➨M.2 SSDs using either PCIe or NVMe offer faster speed compare to conventional SSDs.
➨It occupies less space and look cleaner.
➨M.2 SSDs are not more expensive than traditional SSDs.
➨M.2 SSDs are portable and are lighter in weight.
➨M.2 SSD offers more storage capacity than mSATA card.
➨M.2 drive using PCIe interface offers increased performance. Moreover M.2 NVMe SSDs offer increase in performance and reduced latency.

Drawbacks or disadvantages of M.2 SSD

Following are the drawbacks or disadvantages of M.2 SSD:
➨M.2 SSDs are expensive.
➨M.2 connector supports ports with some specific keys only.
➨The technologies are evolving and it will take some time before we get high performance based cheaper M.2 SSDs.
➨M.2 slots share same PCI bus in old motherboards which affects bus speed.
➨M.2 SSDs with SATA or PCIe have short life span compare to HDDs(Hard Disk Drives) .
