GeekBench 2.3.4 Mountain Lion 10.8 Result The OLD MultiBeast 4.6.1 Configuration for Mountain Lion 10.8(Just for Reference, use the latest Multibeast above) The OLD MultiBeast 5.0.2 Configuration for Mountain Lion 10.8 USB 3.0 is working very well with my USB 3.0 Verbatim Thumb Drive FAQ: Q: Why don't you tick TRIM Enabler in Multibeast? A: My ADATA S510 SSD is a SandForce Based SSD. I have search around the internet and found that there is debate between TRIM is needed or not for SandForce SSD. OWC company (which build SSD based on SandForce as well) officially recommend not to use TRIM Enabler and leave it disabled for their SSD. Information from Stork: MultiBeast incorporates the appropriate TRIM enabler Perl commend. However, since Sandforce controllers perform their own garbage collection, you don't need the TRIM enablers. Q: Why you choose B75M-D3H instead of B75M-D3P which is recommended in the CustoMac? A: GA-B75M-D3P is more expensive than GA-B75M-D3H with additional features that I DON'T need. I choose B75 chips because of its cheap price so I pick the cheapest one that fits all my need. If it is not the $$ that matter, why not go for Z77 instead? DON'T Need features include: - Display port connector. (My monitor do not have one and I am fine with DVI) - Extra SATA 3 ports. (I just need one port for my SSD, and the extra ports are using 3rd Party Chipset "Marvell 88SE9172 chip", not sure if it works with ML 10.8 or not) The features above need extra cost and I don't need it. $$ saved. ADATA SSD ADATA SSD is cheap here in Hong Kong and have performance comparable to OCZ Agility 3. It also included the 3.5inch adaptor.
