LinkMore XE-650 1TB M.2 SSD

We put the LinkMore NVMe M.2 SSD through a detailed test. You can find the test result / test report here:

AS SSD Benchmark

Standard performance test

The standard test was performed with a 5 GB file. A total score of 5395 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	5,801.52 MB/s	5,449.71 MB/s
4K in megabytes per second	63.37 MB/s	189.02 MB/s
4K-64Thrd in megabytes per second	1,740.34 MB/s	1,071.19 MB/s
Access time in milliseconds	0.031 ms	0.517 ms
Score	2384	1805
Total score	5395

Copy performance test

A common everyday scenario is simulated here. Three test folders are created:

• ISO (folder with two large files)
• Program (folder with many small files)
• Game (folder with small and large files)

The three folders are copied using the Windows copy command (cache remains enabled). The real-world test from 03 July 2026 shows performance during simultaneous write and read operations. The lower the duration, the better.

AS SSD Copy Benchmark	Transfer rate:	Duration:
ISO two large files	2,156.77 MB/s	1.07 s
Program typical program folder with many small files	1,141.42 MB/s	6.17 s
Game a game folder with small and large files	1,924.78 MB/s	3.59 s

Compression performance test

Here, speed is measured depending on how compressible the data is.

CrystalDiskMark Benchmark

Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer specs: 7200 MB/s and 5800 MB/s) the LinkMore SSD is measured.

CDM	Read [MB/s]	Write [MB/s]
SEQ1M Q8T1	7,422.10	6,442.59
SEQ1M Q1T1	4,267.43	5,261.32
RND4K Q32T16	3,236.18	1,383.69
RND4K Q1T1	67.52	204.48

HD Tune Pro long-term test

A long-term test was performed to fully utilize the storage. You can see at what point the cache (if present) becomes full and write performance drops. A test file of 300 GB was written to the medium. After approx. 208 GB, the cache was full and performance was throttled.
The test file could at least be read with an average read speed of 4,617 MB/s and written at 385 MB/s.

ATTO Disk Benchmark

Here, a 256 MB file is written to the LinkMore NVMe M.2 SSD multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the LinkMore NVMe M.2 SSD here. The transfer data is displayed. The more consistent the line, the better. Unfortunately, the tool no longer works correctly from around 4,000 MB/s and no line is displayed (and sometimes incorrect min/max data is shown).
