ATTO - Transfer Size vs Performance
I'm keeping our ATTO test around because it's a tool that can easily be run by anyone and it provides a quick look into performance scaling across multiple transfer sizes. I'm providing the results in a slightly different format because the line graphs didn't work well with multiple drives and creating the graphs was rather painful since the results had to be manually inserted cell be cell as ATTO doesn't provide a 'save as CSV' functionality.

Vector 180's performance across different IO sizes doesn't scale as smoothly as on some other drives and especially the read performance has room for improvement.
AS-SSD Incompressible Sequential Performance
I'm also keeping AS-SSD around as it's freeware like ATTO and can be used by our readers to confirm that their drives operate properly. AS-SSD uses incompressible data for all of its transfers, so it's also a valuable tool when testing SandForce based drives that perform worse with incompressible data.

I distinctly remember that when I replaced a SSD in my workstation the Acronis tool, instead of copying my data from the source SSD to the new SSD copied the data to another, unrelated HDD in the system, happily overwriting the Linux partitions stored thereon... I had to unplug everything from the mainboard safe for the old and new SSD to make sure that it doesn't destroy any more of my data.MikeMurphy - Wednesday, March 25, 2015 - link
Macrium Reflect is free and wonderful to use.mapesdhs - Wednesday, March 25, 2015 - link
Yep, MR is what I use, it works very well and has a good interface.

Thirded. It works wonderfully.The_Assimilator - Tuesday, March 24, 2015 - link
OCZ is still beating that Barefoot 3 dead horse for all it's worth. No wonder they went bankrupt. If you don't innovate, you die.ocztosh - Tuesday, March 24, 2015 - link
Hello The_Assimilator. Thanks for your comments. Innovation is definitely a key area of focus for us on both the client and enterprise sides of our SSD business. We currently have a lot of resources put on next generation controllers and have been working hard on client SSDs leveraging the latest Toshiba NAND flash, which includes TLC. While some of these products are on the horizon it was natural for us to update our Vector Series with A19 NAND flash, and rather than just make a NAND change we wanted to add new features not normally found in our client class products like power fail management plus (PFM+) to further improve reliability in applications that blur the line between enthusiast and workstation.It is true that Barefoot 3 has, and continues to be, a very strong platform for us as we have shipped so many drives based on this in-house controller, and it has been so solid that we have not had to rev silicon a single time. We will continue to push to innovate when it comes to SSD performance, features and cost and are committed to delivering more value for all our customers. Thanks again for your feedback.

The bigger problem is that the SSD market has stagnated. When their weren't major players (like Samsung) the little guy could cobble something together and make a decent living filling what was a niche market. Now SSDs are mainstream, and through volume alone the big guys can overpower the little guys, let alone R&D, etc. Until the market shifts away from SATA there's no room for niche innovation or clever advances. It's all down to margins right now.Samus - Tuesday, March 24, 2015 - link
You do realize the two best-selling controllers are Marvell and Sandforce, and both are older than Barefoot 3. The SF2281 is 3+ years old and still ships in a variety of Mushkin, ADATA, Intel, etc SSD's.Barefoot 3 is thoroughly modern, but it does lack some power saving and drive encryption features. I don't think it makes sense for OCZ to update it when PCIe is around the corner and will require a new controller since a bridge will be expensive and not much faster.
Aside from that, Barefoot 3 is incredibly innovative. I consider it the best controller available aside from Intel's 3rd gen controller (equally as old) and Samsung's MEX. ASMedia is still a little inconsistent and featureless, Marvell has an aging indirection table implementation that yields average performance, Phison is clearly entry-level with relatively low performance and consistency, Silicon Motion and Fusion-IO are power hungry, have quirks with certain NAND varieties and are not cost competitive.

"There's an old saying in Tennessee - I know it's in Texas, probably in Tennessee - that says, fool me once, shame on - shame on you. Fool me - you can't get fooled again."Yeah, George, I'm not planning on getting fooled by OCZ again.

Is that the saying from Tennessee where they cant't remember the proper saying?
