How to see if my 820 g3 can use m2 pcie ssd

hi i have hp elitebook 820 g3,which has SSD 256GB M2 SATA-3 TLC 2208 ,i have found a good deal for intel m2 600p series which is pcie interface,so how can i know if i install intel ssd,that i will get nvme speeds

thx

Seems to have some limited support. But the low capacity and the non-existent specification of whether it is PCIe x2 or x4 almost guarantees slower than 2.5" SATA III (sustained) performance.

Only way to tell for sure is to try it. Test before and after upgrading and make sure the two tests are done with everything otherwise the same - except for the different drives, of course.

If you can get an M.2 SSD that you can actively cool (continuously) with a large enough capacity that you can OP by 33% or more, then you may see a significant (real world) performance increase over a 2.5" SSD. Otherwise, you are not upgrading - you're side-grading - and probably at a significant cost too.

Also, keep in mind that the Intel 600P is not the performance M.2 drive to get either...

Good luck.

 

I can return it if im cant make desired speed

 

If your unit has the Samsung SM951 MZVPV256HDGL m.2 PCI-e drive, you know you'll be disappointed in the Intel 'scores'.

I would guess at even a 1TB size and over 33% OP'ing.

That performance consistency (or rather; lack thereof...) in the Intel 600P will make for a very poor system drive when you want snappiness/ responsiveness 'always'. Not just most times...

This is one comparison I would choose to not do - because the outcome is fairly well know.

Intel issued a budget drive with the 600P and a budget drive is barely what is achieved.

 

It was not samsung i think it was sandisk or something like that x400 or similiar..

 

Read again my quote from notebookcheck.net: once we're into SSD's (i.e. past the mechanical storage subsystems...) there will not be much difference in real world usage.

Myself? I'm painfully aware of minute differences in my systems' performance - if you are too, then the Intel 600P may not be the drive for you either (balance it against the larger capacity over your existing SSD system storage drive, etc. - but don't buy into 'M.2' PCIe as being faster 'just because').

The sweet spot for drive speed, longevity, dependability and reliability right now is 1TB or above on any interface currently available (mSATA, SATA III, M.2 SATA or M.2 PCIe x2 or x4) - with 33% OP'ing, of course. And this is from premium drives/nand/processor interfaces...

Expecting anything more from lesser products is not realistic, imo.

What will shake things up in the new year is the latest platforms with 3D Xpoint products installed.

Right now? We're still barely achieving what was promised of SSD's back from 2009 (in real world use)...

 

Do i need to search for nvme driver or just update windows is ok?I got it,i tested assd and speeds are advertised read around 1500/write around 580,but when i run hwinfo i see

Under disks
Red crossed star beside nvme intel ssfpekkw256
And
ATA intel ssdpekkw25
So why is that do i need to install nvme driver from intel site,since there is no any info about nvme driver in intel ssd tool box
