[SOLVED] Anys thoughts on why read /write speed on new 1T SSD is slow?

[owenpga]

Recently installed a new 1T SSD drive into dell E6420 ATG laptop.

here are the numbers i got when i ran the novabench test.

Sandisk recommended i replace the sata cable?

This is the SSD I installed.
Maybe these numbers are ok?

SanDisk SSD PLUS 1TB Internal SSD - SATA III 6 Gb/s, 2.5"/7mm, Up to 535 MB/s - SDSSDA-1T00-G26

Depends on the nature of the test. Can't really say what it was measuring under what conditions.

Something like Crystal Disk Mark is sort of an industry standard.

But still, Up to, not guaranteed for long durations and it would depend on the file size being moved around and all kinds of things.

Really old laptop. Around ~10 years old.
Numbers seem a bit low. But don't expect any better from this old laptop.

old laptop probably on SATA II

BTW - benchmark results on OS drive will be lower than max possible.
That's because windows is reading/writing to the drive in background all the time.

So - those numbers are completely normal.

That would cap it around 200MB/s, so probably is SATA III. Might not be enough bandwidth internally to handle it though given the 2nd gen processor. Too lazy to look up the chipset.
