This review is from: ADATA DashDrive Series UV128 32GB USB 3.0 Flash Drive, Black/Yellow(AUV128-32G-RBY)
Pros: -Device reports a max power usage 300mA. Which is much more frugal then some of the higher power devices.
-Takes advantage of USB 3.0 speeds, a USB 2.0 port will definitely limit this drive for reads.
-Tested read speed was greater then advertised (~68 MB/s).
-Lifetime Limited Warranty
Cons: -Could be faster, but I'd prefer a potentially longer lasting, more energy efficient drive for my use-case.
-Drive does not appear to exceed USB 2.0 bandwidth on writes.
-Tested write speed was less then advertised (~15 MB/s).
Other Thoughts: Formatted drive is around 29GB in capacity.
Here's my benchmarks using CrystalDiskMark 5.0.3, all done using 5 x 1Gib, units are MB/s:
Seq Q32T1- 68.89(R) 14.79(W)
4K Q32T1- 6.578(R) 0.664(W)
Seq- 68.58(R) 10.70(W)
4K- 6.496(R) 0.656(W)
Also tested on a USB 2.0 port (you can see where the reads are limited by USB 2.0 bandwidth):
Seq Q32T1- 32.72(R) 14.42(W)
4K Q32T1- 5.151(R) 0.705(W)
Seq- 32.51(R) 9.228(W)
4K- 4.537(R) 0.661(W)
My drive is running as the OS drive for an embedded Linux device on a USB 2.0 port. It will be run 24x7. No issues for the month it's been in place.
Happy with the higher then advertised read speed, but the less then advertised write speed was the reason I took off 1 egg.
Pros: -Power Efficient
-5 year warranty
-Great performance in the segment
-Able to Route LAN-WAN at nearly 200 Mbps
-PCAP traffic capture from WAN/LAN
Cons: -Single Antenna
-Only single SSID, No Guest SSID option
Other Thoughts: Good packaging, held securely in a recyclable cardboard tray.
Received hardware version 1.0R. Shipped with firmware version 1.00b31, updated and tested with 1.01b09.
The "load" used was iperf. Power measurements taken with a Kill-a-Watt
Excellent power usage/efficiency:
Idle (Wifi on): 1.6W
Load LAN-WAN (Wifi on): 2.0W
Load WLAN-WAN (Wifi on): 2.0W
Load WLAN-LAN and LAN-WAN (Wifi on): 2.2W
Idle (Wifi off): 1.1W
Load LAN-WAN (Wifi off): 1.6W
Routing: Iperf testing shows that this router is limited only by its 100 Mbps WAN port. Using two client and two server processes I was able to sustain just under symmetrical 100 Mbps speeds between LAN to WAN(~94.3 Mbps, just under 190 Mbps bi-directional). Refreshing Steam servers multiple times while playing Team Fortress 2 showed no impact and no issue with browsing on a different system. Ping times remained low throughout this as well. I measured the max simultaneous connections at 3973 - so likely this is around 4096 total connections. Overall this router offered impressive performance for its low-end price point.
Wireless: Wireless coverage is decent for a low-cost, single-antenna device. Performance is acceptable - iperf testing showed real world throughput of around 38 Mbps at a distance of a few feet - Windows showed a connection speed of 130 Mbps. Separating myself by about 2 stories I had much poorer signal, but could still browse the web and stream video without issue. Due to the crowded 2.4 MHz spectrum in my location I was unable to test 40 MHz channel widths.
GUI: The Web GUI is fast, simple, and intuitive. All the usual features found in modern routers are present. One very neat feature is the ability to capture packets from either the WAN and LAN interfaces. When you stop a capture, the packets can be downloaded in a standard Wireshark .pcap file. I'm not sure what the limit is as to how long you can capture for, but this is a valuable tool for debugging. No Guest wireless network option.
Other: Device is light, but has rubber feet to keep it sliding around. 5 year warranty is admirable, but I hope I never have to use it. Through all the testing/loading the max temperature reached was around 92F at the top of the enclosure (~77F ambient). Normal operating temp was much lower at around 80F. Never had to reboot or power-off the router.
Highly recommend for the light user or someone not needing the latest and greatest WiFi coverage. Fantastic bang-for-your-buck.
Pros: -Never need to charge
-Good voice clarity
-Quick to sync to phone
Cons: -I have to turn off the radio myself when I get a call
Other Thoughts: It's been over a year since I first charged it by cord and I have yet to charge it since. Works fantastic and is a heck of a lot cheaper then getting a Bluetooth sync feature in most new cars.
I recommend this to everyone I know who doesn't have Bluetooth integrated in their car.
