I was wondering about this - what happens if the data you want to read is on the same side as you're writing to? would you occasionally get the same slowdown as the 128GB?
on the first page of this review covers my thought and yours
"Unlike a RAID0 array though, data is not uniformly striped across the drive - entire files can be written to specific cells."
so what that means above if data is been saved to an cell should be able to read from others or the other side of the card

Isn't that how Fusion-io achieve relatively much higher speeds (sustained and random) on the ioDrive?
Largely parallel access and overcoming the SATA bottleneck by moving the interface onto PCIe x4?
I would guess since SATA doesn't lend itself as well to sexy marketeering metrics as, say, CPUs or GFX cards no manufacturer feels the need to get in there first.
After all it's only the faster SSDs and external RAID enclosures that are coming close to saturating SATA 3.0Gbps, even then the external enclosures are as likely to be Fibre or SAS, or even external PCIe.
Look at optical drives. How long have we had SATA? But PATA drives are still common enough.
I'm using the Gskill 256 SSD for music production on an 8 core mac with raid card. I have found a way to use the read speed. If I record the majority of my projects on any one of my 15k spin serial scsi drives I can then port over to SSD and do minimal recording while having great speed on large continuos audio files.
I was limited until Apple recently rewrote the driver and fixed the drive issue which caused a restart to not mount. Now it's all good and possibly it would be now a good test to try OSX on this drive.
Just thought I would add this experience to the conversation. I like the drive quite a bit and didn't mind the price. I do wish they would build a two drive 2.5 to 3.5 case so that I could get a second SSD in one Apple slot. I then could try some raid 0 applications and have some fun.

Tbh, I've no idea why SATA 6/9Gs has taken so long?
