It's $500 for 128GB. Isn't it better to just sell rev A, get rev B/C?

Is that a question?
If you can sell rev A at $1k and get a rev B at $1.5k, what's the point? rev B sounds like a bargain.
Hell, if you are going to open it, take rev A display and swap onto the rev B and it's even better.

Taking this thread back from the hijackers...

I received the 128GB unit yesterday and it installed relatively easily.

Since it's the same size as the original Samsung SSD, there were no mods required. I did not transfer the open cell foam "tape" that covered most of the Samsung as this looks like cushioning and well, why does an SSD need this? They probably applied this to all drives at the factory regardless of them being HD or SSD to keep things simple.

Anyway, the drive works great. I installed OS X on it from DVD and performed the lengthy update process - all done now.

This was a great upgrade for me since I feel like I still need to "get my money's worth" out of this notebook since I was an early adopter and sunk $3K into it. Spending another $1800 for a Rev C to get more drive space (which is what I really need) isn't worth it to me.

Hijackers?

Would be interesting to see the performance though, but I doubt it's better than rev B/C SSD.

Is that result with the new SSD? Why is is so slow? That's slower than my old 2.5" 7200RPM Drive.. I'm sure that's almost slower than a 2.5" 5400rpm drive too.

I used a Rev B. SSD MBA for three months or so, and it was almost as fast as my MBP with Samsung SSD right now. And my writing/read speed goes like 190MB/s easily.

Run Xbench many times and see if you get the same results, that looks really really slow for an SSD.

rev B/C's uncached read would reach around 80MB/s.
But not slower than some medicore HDD...
This is a bad upgrade if you can sell rev A.

Photofast seems to have come up with 100mb/s read/write SSD (PF18Z128GSSDZIFV3) too, but the cost will be too high it's not worth it.

Some of us use our computers to run actual applications, not benchmarks.

I had to download Xbench last night to get those results since I've never run it before and had no reason to.

I could perceive no performance difference between this PhotoFlash SSD and the original Samsung unit as far as app loading time, boot/shutdown times, etc.

I'm very happy with this upgrade since it gave me the increased storage with no performance penalty compared to the original drive.

Most of these SSD's seem faster than HDs because of the improvement of multitasking. Of course they can be a little slower at writing data. However, I've heard of SSD's that have issues but i've never experience any slowdown issues myself. I HAVE experienced terrible issues with Runcore and Kingspec.
Avoid for now.

But compared to a 4200rpm SSD's like Smasung's, and perhaps (G-monster and some others) it's like night and day.
