Intel SSD DC S3500 detected as SATA 2.6 compliant

[whitecat]

Maybe there is no problem, but my Intel SSD DC S3500 is detected by smartctl as a SATA 2.6 compliant SSD.
The PDF specification says it's a SATA 3.0 SSD, so I don't know who is actually right.
​http://www.intel.com/content/www/us/en/solid-state-drives/ssd-dc-s3500-spec.html

Does anyone can confirm smartctl is right or not?

I plugged the SSD in 2 different computers (chipset Intel B150 and B85).

smartctl -x

There is possibly no problem. Smartctl prints the SATA level the drive reports in word 222 of the ATA IDENTIFY data.

Please provide output of smartctl --identify ... as an attachment.

smartctl --identify

Smartctl prints the SATA version from IDENTIFY word 222 correctly. Only SATA 2.6 is printed because bit 5 is not set:

Word     Bit     Value   Description
...
 222      -     0x101f   Transport major version number
 222     15:12     0x1   Transport: 0x0 = Parallel, 0x1 = Serial, 0xe = PCIe
 222      4          1   Reserved    | SATA 2.6
 222      3          1   Reserved    | SATA 2.5
 222      2          1   Reserved    | SATA II: Extensions
 222      1          1   ATA/ATAPI-7 | SATA 1.0a
 222      0          1   ATA8-APT    | ATA8-AST

The same value for word 222 is listed in page 34 of the PDF specification. Page 1 reports "SATA Revision 3.0" which would require 0x103f.

You may want to report this mismatch in ​Intel SSD Forum.

OK, thanks for your quick answer.
