P650se which ssd

Hello,

I have a p650se and I'm looking for a ssd. I have found the Samsung evo 850 m2 80mm
So, I saw a post saying that m2 ssd is dangerous on p650se. Is it true?
The laptop will support it and boot from it?

 

Dangerous? It should not be.

You have a slot than can take a SATA based M.2 or a PCI-E m.2 and another than can only take a SATA m.2 (as the 850 evo is). I use a pair of 850 evos in my own system and they are solid drives.

You can also consider the new 950 pro from samsung or the 951 OEM drive if you can find it.

 

Do the ssd come with the screw to hold it in the board?
Is it necessary thermal pads? The 950 is much better than 850?

 

Usually there should be a screw in the computer already, so you wouldn't have worry about getting one of those. For the thermal pad, if you install it without one, monitor the temps and see if it gets too hot (with a program like HWMonitor or others), and apply one if you think it is getting too hot and throttling.

 

Where do I find this thermal pad? It is special for ssds?

 

I've had some people say that they had some in their box when they shipped out, but I'm not sure if that is always the case or not. Otherwise, you should be able to buy some online.

 

OK, thank you

 

Dangerous would be a huge exaggeration. Any SATA SSD, M.2 or 2.5", would, likely, not be any issue in regards to heat. In heavy workflows a 2.5" SSD would out perform an M.2 SATA SSD. It's physical ~ more NAND chips = better parallelism/interleaving. In light workloads they will be close.

M.2 PCIe SSD; it comes down to heat comparing it to SATA SSDs. They are known to throttle because of heat - sustained writing. Control the heat, then PCIe x4 (Samsung 951) should be the top performer. We don't know about Samsung 950 Pro M.2 NVMe yet. But it should be promising.

Otherwise, I'm going 2.5" SanDisk Extreme Pro, all day, in 1TB or 480GB for top performance. Lighter workloads, then price becomes a bigger factor.

 

It depends on the controller chip, the available channels and the number of channels on each chip.

An 850 Evo 2.5" will perform similarly to the 850EVO M.2 equivalent as each chip on the M.2 has multiple die that can be accessed at the same time.

 

Yeah, I forgot to put in - more controller channels = better parallelism/interleaving. The 2.5" may use more channels (8 vs 4) depending on brand and model.

 

In the case of the 850 evo they use the full number of channels (8 i think).

 

It comes down to the specific brand and model. The MEX controller for 1TB 850 EVO (2.5", mSATA, all 850 Pro and all 840 EVO) uses 8 channels. The MGX controller for the 850 EVO 500GB and smaller uses 4 channels. Some 2.5" use the 4 channel Phison controller. While some 2.5" use an 8 channel Marvell controller and the mSATA and/or M.2 version use only 4 channels. Buyer beware or do your homework.

 

Well in the end it's the ultimate level of performance you are interested in. Find a review of the drive and have a look, the numbers should speak for themselves.
