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...

- 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:

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