Kingston A2000 vs WD Black SN750: Which one should you buy?

We have done so many comparisons of the Kingston A2000 with many other SSDs. Also, you will find numerous comparisons including the WD Black SN750 on SSD Sphere. Today, we are going to compare these both with each other. The reason is, they are available at almost similar prices in the markets.

The Kingston A2000 is a DRAM SSD while the WD Black SN750 is a DRAM-Less SSD. So, if you are looking for an SSD with its own DRAM buffer, you should go for the A2000. But, this doesn’t change the game. There are numerous other things to be discussed in the comparison.

The main thing to notice here is the speed offered by the SN750. The top storage variant (1TB) of SN750 can reach up to 3600 MB/s read and 2830 MB/s write speed. But, the Kingston A2000’s 1TB variant can reach only up to 2200 and 2000 MB/s data read-write speed.

So, if you are looking for the best speed, just go for the WD Black SN750. However, if you are looking for an SSD with DRAM, you should choose the A2000.

Theoretically, the SN750 is looking way better than the A2000 in most of the domains. Let’s compare the benchmark scores now.

These benchmark scores are taken from UserBenchmark website. These are average test scores.

ParameterKingston A2000 (1TB)WD Black SN750 (1TB)
Sequential Read Speed1,687 MB/s1,896 MB/s
Sequential Read Speed1,492 MB/s2,092 MB/s
Random 4K Read Speed55.6 MB/s48 MB/s
Random 4K Write Speed149.0 MB/s164 MB/s

You can clearly see that the WD Black SN750 is performing way better than the Kingston A2000 in real-time applications. The sequential read-write speed with SN750 is comparatively impressive.

2 TB1,200 TBW
4 TB2,400 TBW

TBW stands for Total Terabytes Written. The higher the TBW, the longer will be your SSD’s lifespan. So, you can see that the 1TB variant of A2000 is offering a better TBW rating as compared to the SN750.

The prices of both these SSDs are almost similar but, you still have to check before proceeding because they are subjected to regular changes. Generally, you will find A2000 a little cheaper than the SN750.

In terms of performance, the WD Black SN750 is clearly a winner. But, the A2000 is also better in some areas. The best things about the A2000 are its DRAM cache, dual-core controller, and its cheap price. Also, it has higher TBW in the 1TB variant.

But, the SN750 is definitely a good option if you want higher sequential read/write speed. However, it doesn’t have a DRAM and this might be the only thing that might change your decision.

In my opinion, both these SSDs are good.

But, if you are looking for a higher data read/write speed, SN750 is good. Otherwise, if you want a normal NVME at a cheaper price but along with DRAM, you should go for A2000.
