I have found that an M.2 SSD is 50% slower than a SATA SSD when writing to a database.
I have also found that an M.2 SSD is about 4% slower than a SATA SSD when reading from a database.
Here is Setup#1:
SSD: SAMSUNG XP941 Series MZHPU512HCGL-00000 M.2 512GB PCIe Gen2
OS: Windows 7 Ultimate 64-bit
Motherboard: Asus X-99 Deluxe
Application: Microsoft Excel 2013 64-bit
Database: Microsoft Access 2013 64-bit
Here is Setup#2:
SSD: CRUCIAL M550 SSD - 1TB SATA
OS: Windows 7 Ultimate 64-bit
Motherboard: Asus X-99 Deluxe
Application: Microsoft Excel 2013 64-bit
Database: Microsoft Access 2013 64-bit
So everything is identical except the location of the database.
When the database is located on the M.2 SSD, the writing application takes 120 seconds to complete.
When the database is located on the SATA SSD, the writing application takes 80 seconds to complete.
When running on the M.2 SSD, the reading application takes 257 seconds to complete.
When running on the SATA SSD, the reading application take 247 seconds to complete.
Can anyone explain why the M.2 is so much slower when I expected it to be appreciably faster? Is there a problem and how do I go about figuring out if there is a problem or if everything is working as it should?
Thank you.
