Ideapad 700 15ISK R80 very slow write speeds on Samsung PCIe 128GB

2016-09-28, 11:03 AM

My write speeds are around 150 MB/s which is coparable with a SHHD. Read speeds reach around 900 MB/s. Is there anything that can be done?

Lenovo discontinued the 128 GB PCIe version of the Ideapad 700 laptop offering now the 265 MB/s. Is it a problem with the SSD or the compatibility?

I measured the SSD read and write speeds on my Ideapad 700-15ISK (not Y700-15ISK).  I included the results in the following thread; read the first two posts from me on page 2:

My results are comparable to yours.  The quote from "LegitReviews" suggests that the Samsung SSD installed by Lenovo as standard equipment has firmware that intentionally limits performance in order to avoid overheating.  If you purchase a different SSD (or a Samsung SSD not on the Lenovo parts list), you might get better performance.  But you might also get shorter (possibly much shorter) useful life from the SSD, due to overheating.
