Macbook Pro Samsung 840 Series SSD Problems with Yosemite

[r4sh]

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?

 

[r4sh]

I have written above that Trim is enabled.

Hmm. Have you tried repairing disk permissions?

 

[r4sh]

Yes, i did and it doesn't help

Scheisse...

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

 

[r4sh]

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 :/
