I bought a used 2009 MacBook for £140 and installed a 120GB Sandisk SSD Plus. The performance feels similar or slower than the original drive. Since it uses a SATA 2 interface, I thought I’d get about half its capacity, which I’m seeing around 250MB/s on read and 60-70MB/s on write. It seems closer to 200MB/s for writes, but the listing shows up to 400MB/s for reads. Is there an option in MacOS to optimize the SSD for better speed? I’ve already turned on Trim.

We're checking the measurements carefully. Is there a trim involved?

You're using BlackMagic Speed Test, and the trim setting is active. The performance has improved slightly, reaching approximately 80MB/s. Current read speeds remain near 250MB/s.
