Samsung 840 Pro SSD with very high speed ??

Recommended Posts

hi everyone,

 

i was talking to someone on another forum about his SSD Samsung 840 Pro 128 GB and i was curious to know the speed of his SSD so i told him to do a speed test using CrystalDiskMark and he posted the result below :

and after seeing the speed , i logically concluded it was SSD NVMe M.2 so i told him to confirm that it is SSD M.2 and to my surprise he told me that it's not SSD M.2, that his SSD is classic SSD 2.5 sata so i couldn't believe it since a classic SSD cannot logically reach such high speed (1700 Mb/s, 2200 Mb/s)

 

Normally classic SSD 2.5 reach maximum 550 Mb/s speed.

 

He is using windows 10.

 

so my question is , can we reach a such speed with a simple classic SSD 2.5 sata ?

Ok so the mystery was solved, it's because the rapid mode is enabled and when this mode is enabled, the ram is used to cache data which explains why we obtain such high speed at the end of the test.

I talked to a specialist @samsung, and he advised me against this mode.

I haven't tried it on any of my SSDs, BUT I will talk to him again about this

Thank you for your Insight

Please do let us know why the specialist said so, as the company gave the option for customers to enable it. The company should not false advertise if it is not recommended to use that option. Many customers including me who use Samsung's SSD should be aware of the consequence of the Rapid Mode usage.

 

Thanks in advance.

This is the downside of using RAM as cache, but who am I to preach? I'm using PrimoCache:w00t:
