Isn't 130 write way to slow for a Samsung 840 on SATA3?
I'm getting speeds of about 130 write / 370 read on my Samsung840 120GB (non pro) using Black Magic Speed test as things are now, much better than my old Corsair Force3 60GB drive.
I get ~200 write / 250 read with my Samsung 830 512GB on SATA2 in Black Magic. Are these numbers unrealistic?Is Black Magic giving me false data? I'll try some other benchmarks when I have time.
I used to get around 110/130 before I started messing around with the disks being displayed as external, TRIM, AHCI, etc.
@CJP2: Is your SSD displayed as an external disk? Have you enabled TRIM? Maybe try to get these things + AHCI going and report back with new Black Magic results?
I'm still interested in which PCIe SATA3 card to get for maximum performance on 10.8.2. Please share any results and leads you might have!
