Samsung 840 Pro SSD tested and reviewed
Posted by Hilbert Hagedoorn on: 12/12/2012 09:27 AM | 35 comment(s) ]
In this article we test, benchmark and review the Samsung 840 Pro SSD. What a stunning piece of technology this is. An SSD that is extremely fast and actually amongst the handful of fastest storage units we have ever tested. Samsung created a little monster with the 840 Pro series of SSDs, they are remarkably fast in pretty much any and all tests from our benchmark suite. Head on over into the review.

Lol GTFO. OCZ has never used Marvell for their controllers on any of their SSDs. Ever. They have always been Sandforce controllers up until they acquired Indilinx. Also, Indilinx and Marvell are 2 completely different companies and are in no way associated with one another.
Vertex 4 uses a Marvelle controller, they just like to call it indillix.

No he is kinda right, its Indilix hw with marvell bits inside.. At least that's what i've read in one Vertex4 review.

No it doesnt. It has its own onboard memory of 512MB/1GB. The 840 Pro also uses 512MB for cache. They are no different in that regard. The only drives that do not use a dram cache is sandforce. You are not going to lose data because one has dram cache or not. Once the system writes to the nand, its not going to be unwritten if the system crashes.
Ive had my 2 256gb Vertex 4s in RAID 0 for afew months now and have had plenty of crashes when i was doing ram timings and cpu clocks. No data loss at all. Vertex 4 is indilinx 2 controller, vector is barefoot 4 controller which is based off of indilinx.
and wait for firmware updates. Itll get faster no doubt, just as the vertex 4 saw huge improvements from firmware. Dont forget all the drives that died from the first firmware for the 840 pro.
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?

"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

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.

not sure why AS SSD showed the 840 pro with only a total score of 853 , when all the ones benched so far including mine will reach 1200 ish .
-853 is around what the non pro gets see second link.
-also in AS SSD the complete firmware only shows in the non pro that I have noticed ,the pro will show up like in the first link with the latest AS SSD.

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

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.

Yeah, it was a badly worded review I came across, shame I cant locate it.
I'm glad you made me look again.

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.

Thanks for the review, excellent as always.
Ive been running 128gb 840 pro for a few weeks now as my OS drive and although hard to measure it is noticeably more responsive then the M4 it replaced.
Im picking up another 128gb to again replace the M4 which is a dedicated Steam drive.
No issues to report with the 840 pro, has worked flawlessly so far...
