This review is from: ADATA USA UV140 32GB USB 3.0 Flash Drive, Red/Black (AUV140-32G-RKD)
Pros: *** Edit: I am posting this a second time in an attempt to correct my benchmark results formatting below ***
+Consistently fast read speeds
+Good write speeds
Cons: Would have preferred a metal body to it, but its not a big deal for the use I have for it.
Other Thoughts: I purchased two of these to use as a backup recovery drive for two different HP Laptops. I need this size to backup the recovery partition on the laptop in case I ever need it. I could have burned cd's but they take forever when you need to reinstall the operating system, flash drives are far faster than mechanical cd drives.
I will give this 5 stars, mainly due to its consistent high read speed. I am getting similar results in both the ATTO Benchmark and the CrystalDiskMark benchmarks.
Doing a manual file copy to the drive displays very erratic write speeds, but maybe its just Windows 10 not displaying MB/s accurately, I don't know though.
I did format it to NTFS format. My computer desktop is using an MSI Gaming 7 motherboard with its built in USB 3.0 ports, with a i7-4771 cpu.

I have not owned this very long yet, so if I find I am getting different results later on, then I will post them. This flash drive is VERY light weight, and plastic, although many flash drives are. Adata is a brand that has been around a while.
I purchased mine from Newegg which was much cheaper at the time than the current price listed for some other merchant. They do have a blue version also which I think Newegg is the seller.
Pros: +Supports 2.4ghz and TWO separate 5ghz wireless channels. This is great if you have a lot of devices in your home, so that they all aren’t competing for the limited wireless bandwidth.
+Very attractive, small and compact router. It has a good weight to it also. The 6 small 3” antennas also look very nice on it, along with the small blue led lights which are easy to view yet still small. The LED lights only flash when connecting, then they stay on with no flashing. There is one orange led that lights when the internet is not connected yet, or down. Overall I really like the looks of this router, its much nicer looking in person than it is on the photos.
+Great Ventilation. The entire router is ventilated with holes around the entire router.
+The network status is listed as “open” on my Xbox One, which is good, because my previous Netgear R7000 router with stock firmware was not showing open, which caused problems with certain features of games. Open is what you want.
+I am getting very good range with this router, on both the 2.4ghz and 5ghz channels. Just as good or slightly better than my Netgear R7000 router, reaching most areas of our two story house which is 65 feet long. The only areas we have problems with a weak 5ghz signal on all routers, are on an L shaped section of the opposite side of the house.
+Good wired USB 3.0 speeds. I am getting 58MB/s read speed and 42MB/s write speeds with my WD Elements external USB 3.0 drive. With an SSD connected to the routers USB 3.0 port, and transferring a large file to an SSD stored on my desktop (to remove any speed limitations of the drive itself) I was getting 68MB/s read speed and 48MB/s write speed when writing back to the drive connected to the router.
Cons: -It does not appear to display the signal strength of each wireless device connected. This is very disappointing to me, as it’s a feature I use all the time to make sure everything is getting a good signal or not. For a router that is designed to handle many devices, this is the very thing it should have in it.
I did discover that under the Advanced Wireless settings, then Statistics, it does temporarily show the current wifi devices transmit rate which changes when the device is active, but does NOT show the signal strength, which is important to have for debugging reasons.
-The android app for the router currently seems worthless.
Other Thoughts: I am running this router with Time Warner Cable using their Arris TG1672 Cable Modem.
Following the setup on the quick install pamphlet was very easy to follow. It also went smoothly. The router interface is very nice looking also, with a “Basic” and “Advanced” section for configuring options.
The router has a 2.4ghz channel, and two separate 5ghz channels. The first 5ghz channel only allows you to manually set channels 36 to 48. The second 5ghz wifi channel setting, you can only manually choose the higher channels from 149 to 161. The higher numbered channels usually are higher power channels which give longer range, although I seem to be getting the same or slightly better 5ghz signal on the lower numbered channels on this router for whatever reason.
I planned on giving this router a 4 star rating, mainly due to the lack of information displayed about the wireless strength of connected devices. However the router has worked great for me, along with everything I tried so far working without hassle. Even connecting a USB 3.0 drive to the router was so simple and required no configuring to get it running. It has also worked totally fine with my Xbox One along with the other two Xbox One consoles (3 total) of another family living here. So I give it 5 stars.
Hopefully some open source firmware will eventually come out for this router. Or at least I hope they please add a status screen with the wireless strength of each connected wireless device.
Pros: +I am getting very good benchmark scores
+Good price for 480GB
+Appears to have a good policy for warranty claims on the drive if you have problems, but I have not tried it to know for sure.
+3 year warranty
Cons: No cons that I have come across so far.
Other Thoughts: I really like this drive more than I thought I would. It’s definitely faster than I expected it to be. Below I will list my benchmarks scores, but did notice that the drive was fastest on the first benchmark run before I put a lot of data on it. However after it sat a while after the slower benchmarks, then it seemed to regain some of the speed that it lost, most likely due to the Trim improving the drive like it should.
This drive does require an operating system that supports Trim.
I tested this on my Desktop Windows 10 PC.
MSI Z97 Gaming 7 Motherboard
Intel i7-4771 CPU
To compare this drive with another drive I own, I have listed my Samsung 830 Drive first (which is was a very popular ssd drive).

I was surprised that this drive was even beating my Samsung 830 drive in several of the benchmarks. This to me gives it a 5 star rating, as the Samsung 830 was a very popular drive. Such minor differences in speed no one will notice in real use anyways. The OCZ drive appears to be just as thin as the Samsung drive is also, although I did not try this in a laptop. The only main difference I noticed was in the access time for reads, for whatever reason was slower each time after the first test.
Overall I am very happy with this drive so far.
