Rev A with Photofast 1.8 128GB ( XBench 60?!)

[ZACINCCEO]

So I upgraded my Rev A to a Photofast 1.8 128GB ZIF from DVNation (quick ship, wish it came with a screwdriver but still overall easy transaction)

ran XBench and hmmmm seems off.... checked scores and it seems VERY low......


I have to bring it back to get the sound fixed (forget what that parts called.....)


the Disk Test is what seems to has brought things down but am I reading this wrong?

THANKS!!!

I have to bring it back to get the sound fixed (forget what that parts called.....)

It could be noise made by a capacitor. I've had several Apple laptops that suffered from such a noisy, faulty component. Quite annoying if that's the case and you' re right to have the ssd replaced over this.

Those Xbench results are disappointing indeed, maybe this ssd is defect somehow.

It does seem a bit low.

As a point of reference, here's an XBench from my Rev. A 1.6, 80GB HDD 4200rpm results:

It might be correct.

Here are my Rev. A 1.8ghz with 64gb (stock Samsung SLC SSD):

I think we are all seeing slow benchmarks with the Rev. A MBA because of the ZIF/Pata interface. It transfers slower than the Rev. B and C SATA interface.
