A-Data SP900 vs Samsung 840 Evo

[Hank_Tech]

I was looking into getting a ~250GB SSD for my rig, and I am stuck between the A-Data SP900 and Samsung 840 Evo. From what I can tell, the SP900 is just as good as the 840 Evo, and it's much cheaper. They both have about ~550mb/s read speeds and ~530mb/s write speeds. Does anyone know the quality of the flash chips used in the SP900? My guess is they can make it cheaper than the 840 Evo because they are probably using "lower end" nand flash chips and will likely die before the 840. But, I haven't really looked into it, so I have no clue. They both use the SandForce controller, so they are equal there. I have heard that the 840 pretty much the best, if not the best 2.5" SSD you can buy. So should I go with what is considered "the best", or go with the A-Data that looks just as good?

its a great SSD, i got one in my system and i havent had a problem with it

 

it is treu that samsung makes their own NAND flash and that it tends to last longer, hardwareinfo did a great article about it, http://uk.hardware.info/reviews/4178/hardwareinfo-tests-lifespan-of-samsung-ssd-840-250gb-tlc-ssd-updated-with-final-conclusion

 

But in the end if you dont care about the extra money id go with the 840 evo, otherwise the adata one is very good too

AData over Samsung! ( I'm a 840 owner myself ).

I'd go for the Samsung EVO if money isn't a problem

Is the adata the newer one with the marvell m550 insides or a older one with sandforce? If its the newer one id get it as long as you dont think youll see huge benefit from the evo turbo write as well as the rapid ram caching.

Well I could get the one with the marvell internals... What does the marvell have over the sandforce?

not needing compressible data to meet it rated specs as well as just a much newer design in general. ther is no reason to get a sandforce drive now days until the new controller comes out.

Adata is garbage (being sandforce) and also has some specific problems, being one of the rare sandforce drives, that utilitizes 256GB, instead of 240GB of space.

 

Just get m500 or EVO, whatever is cheaper for you. Don't look at specs, because they don't matter that much (especially sequentials speeds).

Sandforce doesnt have issues. I'd go with a 840 evo just for the 1 click firmware update or the useless rapid mode but other than this I'd take the adata if it's cheaper.

You obviously never had sandforce drive(s) then :lol:

I did no, issues.

Good for you.

I have two drives (bought 1 year apart; one asycn and one sync flash) all with the latest firmware and issues are still there (manly trim and occasunal bsods).

One of those is intel which suppost to have its validated firmware --- nope.

And im not alone. Its just that these things were mostly patched. But not fixed.
