What’s the difference between an SSD and NVMe?

SSDs are great storage devices that offer speed and reliability, but they aren’t as durable as traditional HDD drives. NVMe drives are much better suited for desktop users who do a lot of gaming.

We have two types of SSDs in the marketplace today:

Traditional and non-traditional

Traditional SSDs are used for internal storage. They use MLC (Multi Level Cell) flash memory chips, have a 7200RPM spin speed, and are limited to 128GB maximum capacity. Non-traditional SSDs use 3D XPoint (Xpoint) and SLC (Single Level Cell) flash chips, which spin at 15,000RPM, have a theoretical limit of 2TB capacity, and are available in capacities up to 64GB.

In this post, we’ll compare the differences between an SSD (Solid State Drive) and a NVMe SSD (Non-Volatile Memory Express). We’ll talk about why you might want one and how to choose between them.

What is an SSD?

An SSD is a type of storage device that uses flash memory. The flash memory used by SSDs is cheaper than the memory that HDD drives use, but it also has a shorter lifespan. Because of this, SSDs are slower than HDD drives.

HDDs (Hard Disk Drives) are the older storage devices that are still in common use today. They store data using spinning platters and read and write data from and to the platters.

In most cases, the term “SSD” refers to both traditional and non-traditional SSDs. Traditional SSDs are based on MLC flash chips, while NVMe SSDs use SLC flash chips. The newer NVMe technology is much more durable than the older MLC (Multi Level Cell) flash technology.

What is an NVMe SSD?

NVMe stands for Non-Volatile Memory Express. It’s a newer form of SSD that has replaced the older MLC flash chips with SLC flash chips. Because NVMe is so new, there are only a few manufacturers producing it today.

Most NVMe SSDs are made by Intel, SanDisk, Samsung, and Toshiba. NVMe SSDs have higher endurance than their MLC predecessors and can last up to 10 years or more, while traditional SSDs typically have a lifespan of two to five years. The main benefit of NVMe is that it can be attached to both Intel CPUs and AMD CPUs via the PCI Express (PCIe) interface.

This means that the NVMe SSD can read and write data at very high speeds. In other words, the NVMe technology allows the NVMe SSD to outrun the slower speed of traditional SSDs. Traditional SSDs have a SATA interface, which limits the maximum transfer speed. They also can’t be attached to both Intel and AMD CPUs. 

What makes an NVMe SSD so durable?

NVMe SSDs use SLC flash chips. Unlike traditional SSDs that use MLC flash chips, SLC flash chips are more durable and reliable. They don’t lose data like MLC chips do.

How is NVMe different from an SSD?

NVMe drives are faster than traditional SSDs. Traditional SSDs use a single flash chip to store data. NVMe drives use multiple flash chips that work together to store data. This means that each NVMe drive has a much larger storage capacity than traditional SSDs.

Why would I want an NVMe SSD?

If you need a high performance storage solution that will last for years, NVMe SSDs are a great option. They are much more reliable and durable than traditional SSDs. If you game a lot and you want the fastest storage device available, then you might consider an NVMe SSD.

Are NVMe SSDs safe?

Yes, they are. SLC flash chips are more durable and reliable than MLC flash chips. The reliability and durability of the NVMe drives is why they are so popular. Because of their superior performance and durability, NVMe drives are the go-to storage devices for both business and consumers.
