    Hallo all together,

    i have a Samsung SSD 840 Series (not EVO and not PRO) and i did a update on Yosemite (big mistake!). Now im getting write speeds to 50MB and reading speeds to 100 MB. This is a huge minus comparing to 300MB that i have had.

    My specs:
    OS: 10.10.1
    SSD: Samsung SSD 840 Series (500Gig)
    Trim: Enabled
    Macbook Pro:

    Hardware-Übersicht:

    Modellname: MacBook Pro
    Modell-Identifizierung: MacBookPro4,1
    Prozessortyp: Intel Core 2 Duo
    Prozessorgeschwindigkeit: 2,6 GHz
    Anzahl der Prozessoren: 1
    Gesamtanzahl der Kerne: 2
    L2-Cache: 6 MB
    Speicher: 6 GB
    Busgeschwindigkeit: 800 MHz

    The results on blackmagic are devastating (see Attachment).

    I have NOT tried to update the patch for EVO Drives from Sasmsung Official Site because they say it is only for EVO Series.

    Any help/suggestions would be nice.

    Thanks.

    Have you tried enabling TRIM?

    Hmm. Have you tried repairing disk permissions?

    Scheisse...

    You could try installing Mavericks and see whether it makes a difference?

    Ja, scheisse :(

    That is no solution, because i have a lot of files and personal data which need to be reconfigured. Unless there is a way to make the downgrade from Yosemite ...

    Did you make a Time Machine backup before upgrading?

    If you didn't, there's no way to get out of this gottverdammt situation, not even Franz Josef himself could solve it :/
