There is a pro and a con to this situation.

The huge pro is that RM290 price for the 120GB. For current 120GB SSDs, prices start at RM420. Anything cheaper than RM400 is solid 60GB SSD territory.

The SATA 3.0 Gbps performance is not a real issue. You will still feel that the SSD is very fast, and you'll be surprised to feel that SATA 6.0 Gbps SSDs are not that much faster.

The con here is that this model may have compatibility issues. If you are lucky, which is a good chance, than you will be very happy. If you are not lucky, you will need to try to update the firmware and hope it fixed the problem  or find another SSD. If you want to try this SSD, I recommend making sure that you have the option to change to another SSD without much extra cost.

Other than incompatibility problems isolated to SandForce-based SSDs (which the OCZ model you are looking at is one), it is hard to say. There was no report on the exact cause of the incompatibilities. Nor was there a report that all the SandForce incompatibility problems with the old SSDs have been settled. I'd say your chances is pretty good, but I'd also only buy it if I have a way out if the SSD has compatibility problems.

You mean something more current? You're then looking at RM400++ for a 120GB SSD.

Most SSDs should be fine now, including modern SandForce-based SSDs, but there is a standing recommendation to go either Crucial M4 or Intel. For the Crucial M4, you'll need to buy via some of the traders here as they aren't sold in retail stores. Intel's 330 Series are also SandForce-based SSDs, but they have been validated quite thoroughly by Intel. I have even bought a 330 myself and it worked fine in a variety of machines.
