M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Hello, I just wanted to find out the m.2 ssd options available for the ideapad 700 series not the y700.

 

Part # 80RU00CWUS

 

i7-6700HQ Processor

8.0GB PC4-17000 DDR4 2133

1TB 5400 RPM

20160521_191349h.jpg

I had a look at the inside, looking at the hardware manual the samsung pm951 could  be used so does that mean the sm951 could also be used or the 950 pro even?

 

Thanks

decided to go with the samsung pm951 according to the manual. Where i am i won't be able to test the other options like the 950 or the sm951 so its best just go with the manual I'm sure of it to work.

Thanks for the info. I have looked through the manual and found the sm951 in the parts list as well. I'd love to know if I can use the 950 and use it's full speed.

Are you able to get the full 1000Mb/s read speed?

The sm951 and 950 are both m key type its possible they can work work with our machine, I guess the bios would be the problem. i have not bought the PM951 yet.

Hello Smiley Happy, DO you know if Samsung 850 Evo m.2 sata ssd is working on this ideapad 700 too ?
since I see 850 evo m.2 is working with Lenovo y700 so I'm curious.

well, bought the samsung evo 850 m.2 ssd and it works on the ideapad 700. Using crystaldiskmark scores are 540mb read and 467mb write... though when writing to the drive i don't even get 200mb. anyone know what causes this?

Where are you copying the file from? If you are copying files within the m.2 I think it could be hitting the limit of m.2 sata  interface since the drive needs to read and write at the same time.

 

As far as I know the sata iii 6Gb interface has a max speed of around 550MB/s in one direction. So if you are copying files within the same drive you'll have devide the max speed by 2 since you are trying to read and write to the drive at the same time.

 

If you are copying from the sata HDD. The sata HDD cant read as fast as the m.2 can write so it's limited by the HDD. 

 

If you really want to see coping speeds replace the HDD sata and put in a SSD sata 2.5". Then copy files between the m.2 drive and the sata SSD. You should see near max write or read speeds (which ever is lower).

 

Just on a side note I replaced my 2.5" HDD drive with sandisk ultra ii 240Gb. I was thinking of putting in m.2 drive but it was abit more expensive than the equivalent 2.5" drive. So I'm planning to put in a 950 pro in the near future and settle with the sata 2.5" SSD drive for now.

 

I also tested my drive copying within the drive I get just over 200MB/s. If I copy files from my sandisk extreme usb3.0 drive I get near 250MB/s. In Crystaldiskmark I get over 500MB/s in read and write.

I was coping from a Samsung 3.0 external hard drive to the Samsung Evo I got 95mb/s. When coping from the ssd to the external i got about the same.

You are right, if i'm coping within the Evo i get around 200 but it fluctuates.
