Intel 540s 1TB SSD reporting 512 BPS and BPPS rather than 4,096

[RAbra1]

I installed a new Intel 540s 1TB SSD into a new Dell OptiPlex 3040. It is the only drive in the PC. The drive had firmware LSBG200 on it when I received it, but I updated it to the latest firmware (036C) immediately. I installed Windows 10 Pro x64 on it using the latest installation media publicly available from Microsoft's site.

The command "fsutil fsinfo ntfsinfo c:" reports "Bytes Per Sector: 512" and "Bytes Per Physical Sector: 512." I guess I am surprised to see it reporting 512. I would think it would be showing 4,096 for both of those values.

Any thoughts?

Thanks.

Hello Ralph3,

This Word "106" comes directly from the ATA Command Set (ATA8- ACS), therefore, the right way to interpret it is by breaking down 4000h into bits/bytes. Each bit of that word is linked to different purposes, for example (quote from the ATA8-ACS): "If bit 14 of word 106 is set to one and bit 15 of word 106 is cleared to zero, the contents of word 106 contain valid information. If not, information is not valid in this word." For reference, here's the http://www.t13.org/documents/UploadedDocuments/docs2007/D1699r4a-ATA8-ACS.pdf ATA8-ACS spec doc - See sections: 4.12, 7.16.7.52 and also Table 22 for reference.So, 4000h (or 0100 0000 0000 0000) is assigned to 512B in our drives, and for this particular drive, it is a fixed value.For data center drives, it can be changed, if needed, to 4KB (Word = 6003h), see section 5.6 of S3510 http://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/ssd-dc-s3510-spec... spec for reference.Regards,Nestor C
