But if you want to get deeper don’t stop. Continue. let’s get one by one and see how 970 EVO plus is better.

1) Read Speed/Write Speed

Read Speed/Write Speed is important for an SSD because it tells you how fast information can be read from or written to the drive. This is important because it affects how quickly your computer can access data from the SSD.

Well, different capacities have different Read/Write speeds. If we take 1TB of each model they are the same which is Read 3500 MB/s and 3000MB/s. Here I again quote the performance part of both models here

Winner: Samsung 970 EVO Plus

2) Capacity

The capacity of an SSD drive tells you how much data it can store. The higher the capacity, the more data you can store on the drive. The Samsung 980 is available in capacities of 250GB, 500GB, and 1TB, while the Samsung 970 EVO Plus is available in capacities of 250GB, 500GB, 1TB, and 2TB.

I don’t want to explain how important is to have high capacity. If you are a gamer you know that games are becoming more demanding and they require more storage. So it’s important to have a high-capacity SSD drive.

Winner: Samsung 970 EVO Plus

3) Interface

Well, here there is a plus point for Samsung 980 because its uses the latest NVME version 1.4 which was released on March 2021. 970 EVO uses NVME 1.3 which was released on April 2017.

Some of the key changes in NVMe 1.4 include:

  • The new End-to-End Data Protection command set gives the host the ability to protect data written to an NVME device from errors that could occur at any point along the data path.
  • The Host Memory Buffer Access command set allows for latency reduction and CPU overhead by allowing the host to directly access an NVM device’s memory buffers.
  • A new Host Controlled Thermal Management feature gives the host more power over temperature thresholds and cooling strategies for NVMe devices, as well as enhancing Passive State Power Management overall.

are some of them. But these changes don’t make that big of a difference to justify the extra money you will spend on 980. If you already have 970 EVO there is no need to upgrade.

Winner: Samsung 980

4) DRAM Cache Memory

One key feature of NVME drives is the use of DRAM cache memory. This allows the drive to store frequently accessed data in high-speed memory, which can significantly improve performance. The size of the DRAM cache can vary depending on the model of the SSD and the capacity of each SSD. In 970 EVO plus it comes with a DRAM. It comes as follows

DRAM Capacity comes in each capacity on 970 EVO Plus NVME SSD

Unfortunately with 980, you would not get a DRAM. Huge disadvantage. For more info refer to my article on DRAM DRAM SSD vs DRAM Less SSD – A Comprehensive Guide

5) Random Read (4KB, QD1 & QD32)

Random read performance is one of the key indicators of an SSD’s speed. When evaluating an SSD, it is important to look at its random read performance at different queue depths. Queue depth is a measure of how many commands can be queued up for the drive to process at any given time.

A drive with a high queue depth will be able to handle more commands simultaneously, resulting in better performance. The random read performance of an SSD is typically measured in IOPS ( input/output operations per second). The higher the IOPS, the better the performance.

For example, a drive with a random read performance of 4KB at a queue depth of 1 (QD1) would be able to handle 4,000 IOPS. This number would be higher at higher queue depths. If we get back to two SSDs,

  • 970 Can reach up to 17K IOPS – 19K IOPS while 980 will lag at 17K only. (At QD1)
  • 970 Can reach up to 250K IOPS – 620K IOPS while 980 has a range of 230K IOPS – 500K IOPS (At QD32)

If you want to know more que depth follow this article Well this was not written by me I’ll cover this topic in a later article.

6) Random Write (4KB, QD1 & QD32)

In order to understand random write performance, it is important to first understand what random writes are. A random write is a type of file operation in which data is written to a random location on a storage device, such as an SSD.

This is in contrast to a sequential write, which writes data to a sequential block on the storage device. While sequential writes are often faster and more efficient, random writes can be more challenging for a storage device to handle. As a result, the performance of an SSD during a random write operation can vary depending on the specific design of the SSD.

However, newer SSDs often feature advanced controllers and algorithms that help to improve random write performance. As a result, random write operations are typically much faster on today’s SSDs than they were in the past.

If we talk about the two SSDs again

  • 970 Can reach up to 60K IOPS – 62K IOPS while 980 will lag at 53K IOPS only. (At QD1)
  • 970 Can reach up to 550K IOPS – 560K IOPS while 980 has a range of 320K IOPS – 480K IOPS (At QD32)

Winner: Samsung 970 EVO Plus

7) Power Consumption (Idle & Active)

One of the benefits of an SSD (solid state drive) is that it uses less power than a traditional HDD (hard disk drive). The reduced power consumption can result in longer battery life for laptops as well as lower energy costs for servers.

There are two main types of power consumption for an SSD:

  • Idle power consumption
  • Active power consumption (Peak).

Idle power consumption is the amount of power used when the SSD is not actively reading or writing data. Active power consumption is the amount of power used when the SSD is actively reading or writing data.

970 wins at idle power consumption and 980 wins at active power consumption. Well, I am not going to highlight this point here because this power consumption thing is very much irrelevant for an SSD user. Just forget the fact you have other things to worry 🙂

8) TBW (Terabytes Written)

The term TBW, or Terabytes Written, is a specification that SSD manufacturers use to rate the endurance of their drives. It is a measure of how much data can be written to an SSD over its lifetime. In general, the higher the TBW rating, the longer the drive will last. However, it’s important to note that TBW is a measure of endurance, not speed.

Refer to my article Why Does TBW Matter in SSDs?

So, while a high TBW rating is an indication of a well-made and durable SSD, it doesn’t necessarily mean that the drive will be faster than one with a lower TBW rating. While TBW is an important consideration, it is not the only factor to keep in mind when choosing an SSD. You should also consider the read/write speeds, capacity, and price.

if we compare 970 and 980 they have pretty much the same TBW but since 970 comes with 2TB capacity if you can afford it has a massive TBW capacity which is 1200TBW.

Samsung 980 vs 970 EVO Plus ( Similarities )

The Samsung 980 and the 970 EVO Plus are both high-performance solid-state drives (SSDs) that offer fast data transfer speeds and numerous features. Both SSDs use the latest NVMe interface and are available in a variety of capacities.

So let’s give try to find the similarity between these drives

  • Both of these drives use Samsung V-NAND 3bit MLC as the NAND Flash Memory

The Samsung V-NAND 3bit MLC is a type of flash memory that offers high storage capacity and reliability. This technology is based on the same principle as traditional NAND flash memory, with the addition of a vertical cell structure. This vertical cell structure enables the cells to be stacked more densely, resulting in a higher storage capacity. In addition, the use of multiple layers of cells helps to improve data access time and speed.

  • Both come with a max dimension of Max 80.15 x Max 22.15 x Max 2.38 (mm)
