As you read through the data remember the specific specifications for the model MZ-V7E1T0BW Samsung SSD 970 EVO 1TB drive we have are rated at 3400MB/s Sequential Read and 2500MB/s Sequential Write.
In this first graph, we are comparing the Samsung 970 EVO 1TB SSD to the XPG SX8100NP 2TB SSD in CrystalDiskMark SEQ1M Q8T1 Read and Write. The Samsung 970 EVO 1TB SSD is about 3% faster on read performance and achieves over the 3400MB/s rated speed up to 3570MB/s which is excellent.
On Write the Samsung 970 EVO 1TB SSD is 10% faster on write speeds and reaches its rated 2500MB/s write speed. This is a great start for sequential data.
On SEQ1M Q1T1 data there’s a huge difference in the read performance. This time the XPG SSD takes the lead by a large margin, 14%. We aren’t sure why, but we double-checked the result and it was true. However, the tables really turn on the write speed with the Samsung 970 Evo 1TB providing 26% more write performance, which is quite a difference.
Now we come to the random data performance. In RND4K Q32T16 the Samsung SSD 970 EVO 1TB destroys the XPG SX8100NP in read and write performance. It literally has double the write performance which is a really big deal.
In RND4K Q1T1 data the Samsung 970 EVO 1TB also provides higher write performance by 22%.
