xBlue Posted January 19, 2012 Share Posted January 19, 2012 I installed SSD Performance Pro 256 GB on my Macbook Pro 15 from late 2011 - I use Lion OS. I tested the speed with Blackmagic Disk Speed Test and I get 360 MB/s reading and 340 MB/s writing. This is a big improvement from the regular Seagate 500 GB, but still, I was wondering if I should tweak something. So far I've disabled hibernation, hard drive sleep and sudden motion sensor. I haven't enabled TRIM. There is enough free space, so that should not be a problem. Any ideas? Thanks. Link to comment Share on other sites More sharing options...
Toasted Posted January 20, 2012 Share Posted January 20, 2012 Try google some optimization tips for OSX Lion for ssds. I'd recommend you enable TRIM for your SSD. I have read some articles mentioning OSX Lion only enables TRIM for the Apple SSDs not Non-Apple. Link to comment Share on other sites More sharing options...
xBlue Posted January 22, 2012 Author Share Posted January 22, 2012 Yes, that it's true. I read Apple enables TRIM only for their SSDs. However, I read Apple's TRIM is very optimized for their SSDs and actually it may harm other SSDs. Still, when I tested the speed, the drive was new, only had Lion installed, so it shouldn't matter. Any other ideas? Thank you. Link to comment Share on other sites More sharing options...
Toasted Posted January 22, 2012 Share Posted January 22, 2012 You should be fine without any more optimizations. Link to comment Share on other sites More sharing options...
xBlue Posted January 23, 2012 Author Share Posted January 23, 2012 So, it's that the maximum speed for Apple computers? Link to comment Share on other sites More sharing options...
Toasted Posted January 24, 2012 Share Posted January 24, 2012 Notes about the Blackmagic Disk Speed Test as of 2.1 What's New in Version 2.1 Some SSD's use hidden compression when writing data to make their benchmarked speeds appear faster. Disk Speed Test will now measure the true speed of these SSD's so you know if they are suitable for high quality uncompressed video capture. Important note about Solid State Disk (SSD) speeds Some models of SSD cannot save video data at the speed indicated by the manufacturer because the disk uses hidden data compression to reach these higher write speeds. This data compression technique can only save data at the manufacturer’s claimed speed when storing simple files or simple data, such as blank data. Video data includes video noise, and more random pixel data which does not compress much, so the true speed of the disk is seen. Some SSD’s can have up to 50% lower write speed than the manufacturer’s claimed speed, so even though the disk specifications claim an SSD is fast enough to handle video, in reality the disk is not fast enough for real time video data capture. Hidden data compression mostly affects capture and often these disks can still be used for real time playback. Use Blackmagic Disk Speed Test to measure accurately if your SSD will be able to handle uncompressed video capture and playback. Blackmagic Disk Speed Test uses data to simulate the storage of video so you get results similar to what you will see when capturing video to a disk. This will let you find models of SSD that work well for video capture. In our testing, we have found larger newer models of SSD, and larger capacity SSD’s are generally faster. Blackmagic Disk Speed Test also tests the speed of disks connected to eSATA docks and other interfaces, which can affect disk performance.

xBlue Posted January 30, 2012 Author Share Posted January 30, 2012 128GB version on MBP 13 Late 2011 (Lion 10.7.2 clean install, Trim Enabled) Read: 386 MB/s Write: 299 MB/s So, is there anything in particular you configured? To enable TRIM did you use TRIM Enabler or did you do it manually? I enabled TRIM a few days ago, so I will try later today to measure the speed. Also, I think the 256 GB version should be faster, particularly the reading should be above 400 MB/s. Thanks. Link to comment Share on other sites More sharing options...
