SanDisk Optimus GX PRO 8100 2TB M.2 SSD

We put the SanDisk 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 12430 points was achieved.

AS SSD	Read:	Write:
Seq in megabytes per second	11,151.60 MB/s	11,035.00 MB/s
4K in megabytes per second	94.72 MB/s	232.54 MB/s
4K-64Thrd in megabytes per second	3,274.44 MB/s	4,326.02 MB/s
Access time in milliseconds	0.021 ms	0.084 ms
Score	4484	5662
Total score	12430

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 12 June 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	3,936.81 MB/s	0.58 s
Program typical program folder with many small files	1,103.87 MB/s	6.38 s
Game a game folder with small and large files	2,337.27 MB/s	2.96 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: 14900 MB/s and 14000 MB/s) the SanDisk SSD is measured.

CDM	Read [MB/s]	Write [MB/s]
SEQ1M Q8T1	14,863.80	14,071.60
SEQ1M Q1T1	8,874.73	10,826.60
RND4K Q32T16	5,642.96	4,303.24
RND4K Q1T1	102.69	262.84

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 400 GB was written to the medium. The exact cache size could not be determined because the test file did not exhaust (push to the limit) the cache. The test file could at least be read with an average read speed of 10,362 MB/s and written at 10,336 MB/s.

ATTO Disk Benchmark

Here, a 256 MB file is written to the SanDisk 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.
