M2 Speeds

[JD97]

Hi all,

 

I successfully installed my first m2 drive! I did a crystaldiskmark run and I do not know what any of the numbers mean and what should I read to compare to what is advertised. Also, what would be the bottleneck in terms of actually utilizing the max speeds when downloading? would it be the internet speed? 

Photo below is the m2 i installed. I couldnt find any info on the advertised speeds

 

Photo below is my speed test

Looks to be about what its supposed to be at.

Speeds look around what they should be and you would not bottleneck that drive even with fiber 1000 megabit download.

How do you guys know that those are the speeds for it? I couldnt find any info on the m2 drive online about the speeds. 

 

I assume it has to do with NVME?

From your screenshot, you asked CrystalDiskMark to perform the tests using a 1GiB data size (i.e., it creates a temporary file of 1GiB that it can play around with). Then the following tests being run:

• Sequential operation with a queue depth of 32 over a single thread. This is like one task making 32 requests on a drive in locations that are in-order. This is the best case scenario.
• 4KiB requests with a queue depth of 8 over 8 threads. This is like eight tasks making eight requests of the smallest size (4 kilobytes) in random locations on the drive.
• 4KiB requests with a queue depth of 32 over one thread. This is like one task making 32 requests in random locations on the drive.
• 4KiB requests with a queue depth of one over one thread. This is like one task asking for one request of the smallest size in a random location. This is the worst case scenario.

I couldn't find anything specific on the drive itself, other than this page: https://www.skhynix.com/eng/product/ssdClient.jsp
