it scores terribly in this review
"Our second real-life test covers disk activity in a gaming environment. This trace relies heavily on the read performance of a drive. To give a simple breakdown of read/write percentages, the HTPC test is 64% write, 36% read, the Productivity test is 59% write and 41% read, while the gaming trace is 6% write and 94% read. The test consists of a Windows 7 Ultimate 64-bit system pre-configured with Steam, with Grand Theft Auto 4, Left 4 Dead 2, and Mass Effect 2 already downloaded and installed. The trace captures the heavy read activity of each game loading from the start, as well as textures as the game progresses. In this trace we recorded 426MB being written to the drive and 7,235MB being read.
The Spinpoint M9T showed one of the slowest gaming environment performances in each measurement (506.0 IOPS, 27.1MB/s, and 15.8ms), although it was typically comparable to the Hitachi Travelstar 7K500 500GB HDD (484.8 IOPS, 26.0MB/s, and 16.5ms) and the HGST Travelstar 7K1000 1TB (482.2 IOPS, 25.8MB/s, and 16.6ms)."
slowest gaming environment performance
compare that with
"The new WD Caviar Black is by in large one of the fastest 3.5" HDDs on the market today with its target users generally being those looking for the most explosive performance available in an HDD, without giving up capacity. Along with its top-in-class performance, the new WD drive also features Vibration Control Technology, or VCT, which allows the platters to adapt to any mounting problems or vibration conditions. As a result, this increases reliability, accuracy, and performance over time.
In our tests, we found the new WD Black Caviar 4TB performed significantly better overall compared to the other 7,200RPM hard drives with the exception of the Hitachi 7K4000, which kept pace in a few categories. In mixed workloads, the new WD Black was frequently at the top of the pack by quite a large margin--especially when it came to throughput--with sequential read transfer performance clocking in at 20MB/s higher than the closest HDD. The updated WD Black HDDs promised higher performance of up to 48 percent, better accuracy, stronger reliability and a greater efficiency; it delivered just that, making this a highly recommended HDD.

as for it being unnoticeable i seem to notice i have picked up all my bounties before anyone else in the fireteam has even loaded into the tower in destiny. so in those circumstances i need to wait for them but when i'm on my own loading into a game, daily, mission, etc will be faster saving me some time.
especially when it comes to playing single player games like the last of us, tomb raider, etc. the stuff in the background loads up quicker and less time for stuff to pop up, etc.
I need to upgrade now and this seems like the best in terms of performance and capacity.
I don't care how it looks, that should be obvious, I don't look at the console I look at the screen when gaming funnily enough.
So it looks like the WD Black is the one to go for.
