ADATA XPG SX930 (120GB, 240GB & 480GB) SSD Review: JMicron JMF670H Debuts

The Light trace is designed to be an accurate illustration of basic usage. It's basically a subset of the Heavy trace, but we've left out some workloads to reduce the writes and make it more read intensive in general. Please refer to this article for full details of the test.
It's been common knowledge for quite some time that for light client workloads, the differences between SATA SSDs are mostly negligible and the SX930 doesn't change the story. It's a decent performer, but can't offer any advantage over its alternatives.
The SX930 is quite power efficient, although it can't challenge the BX100 in this area.

Oh really? Was it another firmware update for the 840EVO? When? I just threw my 840EVO out about 5 days ago after 2 firmware updates this year which did not fix the problem. The last update I had, Samsung had some kind of optimization in "Magician" (lmao) by moving all the old data to new blocks. Yeah ok, I had that 250GB EVO filled with about 190GB. It took like forever to finish and the optimization had to be run frequently in order to keep the 840EVO runs near advertised specs."Vitriol" or whatever, I would take any SSD with JMicron controller over the 840EVO in a heart beat. At least I wouldn't feel like being cheated out of paying for something that it's clearly NOT!
I'm thinking anyone that purchased the 840EVO should get together and file a class action lawsuit on Samsung for faulty advertising, consumer fraud or something like that.

Can you get a replacement under warranty?Oxford Guy - Sunday, July 19, 2015 - link
"Samsung has made 1 slip-up that was fixed with a firmware update."False. The 840 and 840 EVO drives reportedly have a permanent TLC-caused flaw. The only thing Samsung has managed to do, last I heard (and that was two "fixed" later) is re-write the data over and over again to paper over the problem.
The TLC is too weak to avoid voltage degradation so data needs to be rewritten to prevent massive slowdowns in read speed. I don't think Apple has ever bothered to release anything to fix the Samsung OEM drives they put their brand on either.

Interestingly, too, Apple decided to dump TLC, at least for its mobile line, sometime ago -- citing the inherent flaws. One could look at that move as being part of their feud with Samsung but I doubt that was the main motivation.zodiacfml - Sunday, July 19, 2015 - link
that's what truly happened. it only worked good when it was new.jabber - Monday, July 20, 2015 - link
Running SATA II? Buy the cheapest Kingston V300 as it will push 275MBps all day long.Running SATA III? Buy a BX100 and be done with it.

the firmware update really did the trick .. it has improved by a lot... I request anandtech to another review on this....
