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.

LOL @EVO 3-bit NAND...I just threw out my 1 year old 840EVO 250GB which was the worst SSD I've ever had. MX200 500GB is in and I wish I could've got this one from the begining instead of the EVO junk.

Just curious, what problems did you encounter?fokka - Thursday, July 16, 2015 - link
i guess the same as so many others, which still has no real fix: http://www.anandtech.com/show/8550/samsung-acknowl...Impulses - Thursday, July 16, 2015 - link
That's not about the 850.Adding-Color - Thursday, July 16, 2015 - link
What not about the 850? OP was talking about the 840!futrtrubl - Thursday, July 16, 2015 - link
Actually the OP was talking about something to challenge the EVO, the latest of which is the 850.Samus - Saturday, July 18, 2015 - link
What proof does anybody have the 850EVO is going to be any difference than the 840EVO with performance degradation. They use the same technology and only the 850PRO get's the binned, lower node 3D VNAND.voicequal - Monday, July 20, 2015 - link
The 840EVO was on ~19nm NAND. The 850EVO uses 40nm V-NAND which should provide much greater cell integrity needed for TLC operation.sonny73n - Friday, July 17, 2015 - link
What about the 850? After my experience with that "EVO", Samsung 3-bit TLC NAND in particular, I had lost interest and trust in Samsung. The 830 Pro 128GB I had years ago was excellent though but it took a chunk out of my pocket. So I guess when it comes to value for the money, I should always look somewhere else.bug77 - Friday, July 17, 2015 - link
Then you don't know that the 850 EVO has *nothing* to do with 840 EVO. Not surprising, otherwise you wouldn't have bought that PoS. The planar TLC is bottom of the barrel, with slow access and probably under 1000 P/E cycles. The 850 EVO uses 3D NAND which alleviates those issues.So you see, it really wasn't an 840 EVO problem, it was a planar TLC NAND problem. Many cheap drives still use that.
