moebear — Wed, 19 Aug 2020 17:52:46 GMT

as title, you can see the problem in the following pictures.

1. This is my ssd and it's info, read 870, write 484

Disk info in English

2. The following one is I found in internet.
512GB 660P, also used as C: , you can see its speed is almost twice than mine.

3. The following one is I found in internet too.

256GB, 660P ,you can see its speed is almost twice than mine.

Hello, @moebear.

Thank you for contacting the Intel Community Support.

I checked your ticket regarding the performance of your Intel SSD 660p, I will be glad to assist you.

There are many different factors that could be causing different readings:

- The SSD model is different: They are the same 660p Series, but some specifications may slightly vary.

- The percentage used is different (his is 12% and yours is 41%): The best option would be to prepare the drives by performing a secure erase (or several).

- The systems are different: There could be unknown factors involved.

- His seems to be a clean/new OS install: Other processes running in the background that we are not aware of could be affecting your results.

With this being said, here are some recommendations:

1. Make sure you install the latest "Client NMVe drivers" from Intel: https://downloadcenter.intel.com/download/29172/Client-NVMe-Microsoft-Windows-Drivers-for-Intel-SSDs

2. Perform a firmware update using Intel Memory and Storage Tool (the tool will inform you if there is new firmware available): https://downloadcenter.intel.com/download/29704?v=t

- It is recommended to keep a backup of your information in case something happens during any firmware update process.

3. Run the "Performance booster" using the same Intel Memory and Storage Tool: This should clear the cache of the 660p allowing for better performance.

Run the tests again and let me know if you notice any changes in the results.

Hi, today I notice that 660p 256g is not available on market, so there is nearly no any speed test data on internet

The attachment picture I post yesterday is 600P 256g and 660p 512g.

So their speed test data are useless.

The retailer who give 660p256g to me post their 660p256g's speed test data which is close to mine.(915 read / 483 write)

So I think the speed test data may be correct, 660p256g's r/w performance is like that.

But in the same 660p series, 256g only has nearly half to 60% speed of 512g's .

This is so incredible.

- His seems to be a clean/new OS install: Other processes running in the background that we are not aware of could be affecting your results.

I tried doing speed test by windows safe mode and it is the same.

1. Make sure you install the latest "Client NMVe drivers" from Intel:

I install before ask question.

2. Perform a firmware update using Intel Memory and Storage Tool (the tool will inform you if there is new firmware available)
I install before ask question. and there is NO FIREWARE UPDATE for 660P 256G, 004C is not avaliable for 660P256G.

3. Run the "Performance booster" using the same Intel Memory and Storage Tool: This should clear the cache of the 660p allowing for better performance.

done before ask question.

Hello, @moebear.

Thank you for the response and all the information.

As you mentioned, this seems to be a special version of the SSD 660p and there are no specific details available in order for us to compare.

The recommendations provided before are just general recommendations that can be applied, but knowing that you already contacted the vendor and you confirmed that your results are similar to the ones provided by him, there are no further recommendations we can provide as the drive may already be running according to specification.

You can check with them if there is something else you can try or in case there are other details they can provide, additionally, if the unit came preinstalled in the system you are using, you may also contact the system manufacturer (OEM) for more details or support regarding its performance.

This product is manufactured by Intel.

I'd like to know whether this product is originally run with nearly half speed of others in same series

or just vendor and I use the wrong way to test this product.

or Intel community can't ?

Hello, @moebear.

As you have mentioned before, this unit is not officially available for purchase and specifications are not available in the ARK website, it could be a limited run or a "region-specific model".

- Intel SSD 660p Series list: https://ark.intel.com/content/www/us/en/ark/products/series/149409/intel-ssd-660p-series.html

Since you already have tests that show similar results (from your vendor), there is no firmware update and the latest Intel NVMe driver is installed, there are no additional recommendations or details for us to provide, except for performing a secure erase on the unit and test it as a secondary drive as described in the Intel SSD 660p evaluation guide, starting on page 8 (Section 3, System Tuning):

- Evaluation guide for 660p: https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/consumer-ssds/Intel_SSD_660p_EvaluationGuide337971.pdf

- Keep in mind that the 256GB version is not listed there either and this guide is being provided as reference.

You may check if following those steps provide an improvement.

In order to try to get more details about this model, please let me know the following:

1. Is this the correct ISN BTNH9226065J256D?

2. Was this product purchased as Brand new in original Intel packaging?

3. Did the unit came pre-installed in a desktop or laptop?

4. What is the store or website where you purchased the product?

Hello, @moebear.

Thank you for the details.

When I mentioned "ticket", I was referring to your support ticket/thread/forum, you can disregard that.

Please allow me work on this and I will contact you back as soon as possible.

Hello, @moebear.

Thank you very much for waiting.

More details about this specific model are not available, right now the best option is to contact the vendor who provided the unit, if they can provide you with their benchmarking results, you can use them to compare your drive; the document I mentioned before can also be used as a reference on how you should prepare the drive and the system before performing the benchmark.

I will proceed to close the thread right now as there are no other recommendations or information we can provide due to the drive being a promotional/special edition and the best option would be to contact the point of sale or vendor for additional information.

If you require any type of assistance in the future, please open a new community thread as this one will no longer be monitored.
