tlmlvr Posted August 7, 2013 Share Posted August 7, 2013 I have a Corsair Force-3 360 GS firmware ver. 5.05A installed in my Macbook Pro 15 inch. Model 8.2. The SSD was divided into two volumes: one for Mac OS, other for Bootcamp with Win7 Professional. On Win 7, the WEI shown the score of 7.4, but when I ran ATTO my disk max. performance was at the transfer size of 4096 KB: 313 MB/s for both Read and Write. A similar test result on CrystalMark: 293 MB/s Read, 280 MB/s Write. CrystalDisksInfo 5.6.2 said I have SATA /600, also confirmed on Mac OS side. How can I tune to get the bettter disk performance ? it should be at least 400 MB/s on both read and write operations right ? Thanks Link to comment Share on other sites More sharing options...
Toasted Posted August 8, 2013 Share Posted August 8, 2013 If the ATTO results are normal. Then the drive is working fine. Corsair uses ATTO for their advertised SSD speeds. Link to comment Share on other sites More sharing options...

Yes, the drive has been working fine in my macbook for last 2 months. I just wanted to justify the performance i.e. get what I paid for. Ads: Corsair Force GS Series CSSD-F360GBGS-BK Performance Max Sequential ReadUp to 555 MB/s Max Sequential WriteUp to 530 MB/s 4KB Random WriteUp to 50,000 IOPS My macbook has been operating with minimum write operations, the SSD degration should not be an issue. Trim was activate on both side. I expected ATTO give me the performance at least 400 MB/s for both sequential read and write ops. I did perform the ATTO test with mimnimum operation running, even without Ethernet browswer. Link to comment Share on other sites More sharing options...

You might want to check and see if your Macbook has a SATA 3 connector or is it SATA 2. Link to comment Share on other sites More sharing options...

How can I tune to get the bettter disk performance ? it should be at least 500 MB/s on both read and write operations right ? Thanks Read other posts, Force-GS3's read performance should be 500 - 530 MB/s. does it mean my SSD is "under-performed" ? need refresh ? my Macbook is for personal use, I don't read and write a lot of data daily: the SSD was installed not long ago (about 2-3 months). Any guru would like to have few words on this ? Link to comment Share on other sites More sharing options...
