Updated to A15 Bios for my 3 year old Alienware 17 labtop. Disk operations and processing slowed after update. Drive is a Samsung SSD 840 1TB. Before updating to A15 bios seq Read was 3,340 MB/Sec Write was 2766 MB/Sec. After upgrade disk slowed to :1984 MB/Sec READ and 1347 MB/Sec WRITE . I could not live with the slow down so I reverted back to A14 bios. WRITE and READ speeds returned to normal. I know A15 bios update is to fix the security flaw in the intel Chips ( CVE-2017-5715) However, the slow down is unacceptable!!!! Does anyone have any Ideas? I want the security update but can't live with the slow down!
