ReadSpeed interesting SSD result

[dragosmp]

Hello everyone,

Long time listener of the podcast and user of Spinrite here, but just signed up for the forums. Everything was clear, so never felt the need to. So I downloaded the Dos exe and ran it on my Dell Latitude 7280 26GB m.2 SSD. I'd like to mention the SSD felt snappy and in two years since I have this laptop I never did any particular maintenance on it, outside of not partitioning about 20GB from the get-go in order to boost the over-provisioning pool.

1st run:

Driv Size  Drive Identity     Location:    0      25%     50%     75%     100
---- ----- ---------------------------- ------- ------- ------- ------- -------
 81  256GB LITEON CV3-8D256-11 SATA      359.5   232.3   251.5   269.2   526.8

It was a bit all over the place, so I ran a L3 Spinrite. Results after Spinrite are much more consistent, but somewhat low (was expecting 500Mb/s or more):

Driv Size  Drive Identity     Location:    0      25%     50%     75%     100

Any thoughts?

Thanks!

Update, tested a few days later (seems to be very consistent from a test to the next):
