Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Hi Luang,

 

Thank you very much for you share !

I'm happy to see that the new 960 PRO is working on our machines !

By any chance, could you give us a CrystalDiskMark or Magician Performance Benchmark screen copy ?

 

For information, as far as I read on the recent november 15th Tom's Hardware bench, the 960 EVO 256 Mb is not advised at all :

<<

Everyone has done something that they regretted as soon as they took the action. Samsung may feel that way about the 960 EVO 250GB because it took the low-capacity model down one step too far. Using lower density flash should have helped, but the final result doesn't match our, or your, EVO series expectations.

Cheers,

Maurok

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

I also have an ideapad 700 and I thinking about acquiring an m.2. Lenovo manuals indicate only m.2 of 128/256 Gb.

The latest BIOS update allow 512 Gb or More?

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Hi,

 

Finally I decided to buy the SM961 256GB which is the OEM version of the 960 PRO (because the 960 PRO is more expansive and does not exist in 256 Mb capacity).
I odered it at www.mindfactory.de for 120 € (+ 20€ UPS transport to european country). They had the product in stock but the prices still tend to increase and the availability of the 960 serie is stil a problem.
The firmware version I had is the CXZ7300Q and the manufacturing date is december 2016. See the CrystalDiskInfo screenshot and the chip picture :

CrystalDiskInfo SSD.jpgSSD SM961.jpg

 

Good news : this SSD works with our machines so I am pretty confident that all the 960 PRO/EVO types should work.

 

Here is how I proceed for the installation :
- upgrade the BIOS of my laptop from E5CN53WW to E5CN56WW
- check the UEFI was configured in UEFI mode and not in BIOS legacy mode
- boot on USD stick with Windows 10 installer on it
- install Windows 10 on the SSD

 

Then everything seemed to work well until I deceided to remove my old Windows 10 installation on the HDD (Lenovo original).
To do so, I used the USB stick with Windows 10 installer and erased all the partitions of the HDD (windows, recovery, drivers, EFI, MSR...) (I could have just reformated the Windows partition but I like clean installations !). Then I was surprised to see that my PC didn't boot any more !
I think it is because, even if Windows was installed in the SSD, the EFI partition was created on the HDD. But, in my opinion, this is not good because in the case of a HDD failure, the PC would not be able to boot on the SSD ! Additionnaly, for performance reasons, I don't want Windows to fetch data from the HDD at boot time or whenever.

 

So, in order to correct this, I proceed to a new installation following those steps :
- unplug the HDD physically (because is not possible to just deactivate it in the UEFI menu)
- boot on USD stick with Windows 10 installer on it
- remove all partition on the SSD and install Windows 10 on the SSD
- check Windows 10 can boot without HDD
- plug the HDD and erase all partitions on it (using again the USB stick Windows installer)

 

Now, I am sure Windows is 100% installed on the SSD and the HDD is reserved for my data.
Here is the picture of the Windows partitions in my final installation (in French sorry) :

Partitions.jpg

 

Last but not least, here are the SSD performance results measured with CrystalDiskMark :

CrystalDiskMark SSD.jpg

 

 

If we consider the QD32 perfs (the commercial brochures are based on this ideal test conditions) we have the following results :
- Sequential read 3253 MB/s
- Sequential write 1527 MB/s
- Random Read 132K IOPS (=516/4*1024)
- Random Write 113K IOPS (=442/4*1024)

 

Those results have to be compared with the commercial claims for SM961 256GB which are :
- Sequential read 3100 MB/s
- Sequential write 1400 MB/s
- Random Read 330K IOPS
- Random Write 280K IOPS

 

While the commercial claims for 960 PRO 512GB are :
- Sequential read 3500 MB/s
- Sequential write 2100 MB/s
- Random Read 330K IOPS
- Random Write 330K IOPS

 

Interpretation :
- the sequential results are very good (105 % reading and 109 % writing compared to commercial claims).
- the random (=4K) results are bellow commercial claims (40 % for both reading and writing). I think this result is normal because "helloti" eralier in this forum had the similar level of performance on the 950 PRO 256 GB (about 50 % for both reading and writing compared to this chip commercial claims). Samsung probably makes this measurement in quite different conditions (may be with file size different than 4K  ?).

 

Conclusion :
- comparing with the 950 PRO 256GB, the SM961 256 GB gives similar results for a normal basic usage (reading, single thread, random) and much better results in hard condition usage (writing, multi thread, sequential). Additionnaly the SM961 is much cheaper (120 € versus 220 €).
- comparing with the 960 PRO 512GB, I supposed the performances would be very simlar because the commercial specs are. Additionaly, even if the capacity is half, the SM961 is much cheaper (120 € versus 310 €).

 

So I am very satisfied with the SM961 I bought, because it is perfectly compatible with our laptops and because its performances are excellent !

 

Cheers,

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

I'm a bit confused... Smiley Sad

 

Which 512 GB SSD should I buy, the 960 PRO or the SM961? The SM is cheaper and actually it performs better in tests but it's an OEM version and comes without the 5-year guarantee, whereas with the 960 PRO you get the 5-year guarantee, support and the Samsung Magician software in addition which makes it easy to update the firmware, however it is not as fast as claimed in the official specification...

 

So with this in mind which one would you recommend? And please correct me if I'm wrong in something. Smiley Happy

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Hello akislb99,

Personnaly I don't think the 5 year waranty is very usefull but the posibility to update the firmware is very important !

I would be very surprised the performance of the 960 PRO to be lower than SM961 as it is exactlly the same hardware. The 960 PRO should be better from now and later on because it's firmware can be updated so it will take advantage of the comming Samusung software imrovements !

The price difference between 960 PRO and SM961 being quite low (275 € vs 325 €), I would choose the 960 PRO because it is a better investment for the future.

My case is different because I needed a 256 Gb capacity (I have a second magnetic HD inside my laptop) and the 960 PRO des not exist in the capacity.

Regards,

Maurok

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Hello akislb99,

I think the EVO 960 (250 gb) is the alternative. Also the drivers work with Windows 7, 8.1 and 10.

Pd: I believed that sm961 does not boot with Windows 7.

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Well, thank you but the EVO is not really an option I would want to go with and I'd put Windows 10 on it so booting is not a problem either. I just don't really understand why the 960 PRO doesn't reach those speeds described in its specifications and how can the SM961 perform better than the 960 PRO in benchmark tests if it's slower theoretically.

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

akisbl99,

- "960 PRO doesn't reach those speeds described in its specifications"

Like all the SSD, this is normal, marketing is not benchmark !

- "how can the SM961 perform better than the 960 PRO in benchmark tests if if it's slower theoretically"

The benchmark you posted (benchmark SM961 vs 950PRO) does not that : its says 3% difference which is nothing because greater than the measurement error. So we can say that the performances are exactly equal (with tody's firmware).

The hardware is the same so it's normal the performance are equal. Maybe in extreme usage (like pure sequential read/write) you could have a difference because of the firmware optimizations.

This is exactly what is meant by the commercial claims : "buy the 960 PRO, you'll will have better performance in extreme conditions because tou can update the firmware."

commercial claims :

SM961:
 Sequential Read : 3,200 MB/s
 Sequential Write : 1,700 MB/s
 Random Read (4KB, QD32) : 330,000 IOPS
 Random Write (4KB, QD32) : 300,000 IOPS

960 PRO:
 Sequential Read : 3,500 MB/s
 Sequential Write : 2,100 MB/s
 Random Read (4KB, QD32) : 330,000 IOPS
 Random Write (4KB, QD32) : 300,000 IOPS

Re: M.2 SSD OPTIONS FOR IDEAPAD 700 15ISK

Ok, the wording I used wasn't totally correct, I'm sorry. What I meant by saying the SM performs better is that it is close to the speed in its specification and the PRO performs only on the level of the SM. So there is no remarkable or noticable difference between them even though based on the specifications there should be.

I agree with you : same HW = same perfs !

For 50 € more, you just have the possibility to upgrade the firmware and hope you'll have in the future some improvements in extreme condition usage.
