Indilix hardware with Intel and Micron parts.
"Under the hood the drive is all new. Vector uses the first home-grown SSD controller by OCZ. Although the Octane and Vertex 4 SSDs both used OCZ Indilinx branded silicon, they were both based on Marvell IP - the controller architecture was licensed, not designed in house. Vector on the other hand uses OCZ's brand new Barefoot 3 controller, designed entirely in-house." From anandtech review of vector. So yes, Vertex 4 used marvell
Soz to bring this up again, but there may still be an issue with the Vector. I'm wondering if you know about this... The Vector has its own DDR3 controller for caching, so could still lose data stored in the DDR3 on a power down unless the cache can be committed to the SSD in time, or it has a battery backup. Do you know if there is any protection in place to prevent data loss?
Yes, some SSDs(mainly enterprise drives) incorporate large caps, aka supercaps(ocz) that are designed for data loss protection when power is lost. They keep the nand powered long enough for the dram controller to write the cache to them. They basically store power for a short time. I know the Vertex 4 uses supercaps but unsure about vector, wouldn't be surprised if it did as its based off of the indilinx in vertex 4. I can tell you for sure that neither the samsung 830 or the 840 have protection against data loss.

I had a derp moment there. My bad. I believe I have gotten the 2 controllers mixed up.

AS SSD Score AS SSD score is definitely low. I saw that score and it is incredibly low. I have a 840 pro 256gb in my laptop and I got a 1181 score, outside of that, everything looked normal. Something went terribly wrong with that benchmark. They should run that again on another system and make sure there is nothing wrong with that particular drive. I replaced my neutron gtx with an 840 pro and it scored considerably higher than the corsair drive but I also have nothing but praise for that drive as well. I actually get an extra 30 minutes of battery life with 840 pro vs the neutron gtx on a HP DV7-7000 series laptop with a 9 cell battery.

Thought I'd pop back to confirm my earlier fears of the OCz Vector are unfounded, I now own the 256GB. Its great, handles problems as well as my old SSD, it gives no issues. Read data transfer rates are 350MB/s where there is data, (300MB/s on blank areas), using HDTune to test. Neat drive, its pretty heavy, feels almost like solid metal. It came free with Acronis backup 2012 and a 3.5" bay mount tray.

Your SSD reviews are excellent, Hilbert, i've one of these samsung Pro SSDs arriving tomorrow(128gb version) , hope it's at least a bit faster than my force GT. 🙂

I got the SSD, the 128gb version, it's as light as a feather, i'm very pleased with it, haven't done any tests yet but i seen it load windows quicker than anything before it so it's all good no doubt. currently using it as main system drive, then my other 128gb ssd for games, and my lil' sata2 32gb one for explorer temp files and the like.

Yup. The 840 Pro is great. Got two 256GB ones in RAID 0. For some reason the 512GB model is usually more expensive than two 256GB ones. So, this way I still have a large faster one for less money. 😉

Good bit faster read speed than my Corsair force GT, and double the write speed. Couldn't be happier. *I knocked my cpu heatsink outta place when installing and thought the 840 pro must be a cpu hog after the wild temps i was getting. *ahem

Early Marvell SATA 3.0 controller, the results are fine in my opinion.

I would have got the Samsung if they did it in a big enough size for me at the time i was buying, as they are great SSD's.
