This review is from: WD Purple WD20PURX 2TB SATA 6.0Gb/s 3.5" Hard Drive
Pros: Designed for 24/7/365 use for camera systems, but still usable in other scenarios.
Performance for usage scenario is good.
Cons: Warranty not as long as black and enterprise drives, again these aren't designed to be in that segment.
Slower overall speed even when compared to standard 7200 RPM drives, though these are designed this way on purpose.
Other Thoughts: I was actually quite impressed with the performance of this drive. On my Z97 platform I was able to get over 100 Megabytes a second transfers going when the drive was empty. Not bad for a drive that isn't really designed for speed. Bursts were over 300 megabytes a second for an empty drive.
In my Synology Cloudstation I was able to record 5 different cameras without any stutter from the drive. Even when reviewing the recorded video the playback was smooth even while recording in the background. I can't say for sure on a system with more than this that there wouldn't be stutter, but for my needs it was good.
Overall I've had nothing but good success with WD drives. I've only ever had 1 be DOA (dead on arrival) but was easily replaced by WD's support group.
I definitely prefer these over the WD Green Drives. Those are nothing but super slow and honestly have had a higher failure rate from what I've read than any other WD drive I've ever seen.
This review is from: DEEPCOOL M3 Laptop Cooling Pad 15.6" with 2.1 Speaker System 140mm Fan
Pros: The speakers are loud and can fill a decent size room. Even at high levels I didn't experience clipping. Sound was clear and not muddy at low levels.
Big improvement over laptop speakers. Even nice ones (mine are JBLs but I also tested with a Beats enabled laptop as well).
Fan was quiet and moved a decent amount of air. During gaming or even normal use my hands didn't get hot.
Price is really nice for what you get.
Not too heavy either given it's size.
Cons: I really wish I didn't have to run a separate (included) 3.5mm audio cable for the sound. Since you're already powering via usb, it would be nice to just have the audio come out via USB. That said, I'm sure that would cost more, but just a thought.
A little big, but not uncomfortable on my lap.
Other Thoughts: While not the most comfortable for laps, I still think this cooler has it's place. It cools well and the sound is really quite good. Having the speakers on the back side of the monitor can be a little annoying as it does slightly alter the sound a little, but not so much that it really matters.
My temps from cooling went down about an average of 8-10 degrees Celsius with the fan pushing cooler air directly into the intake fans of my laptop.
Overall a solid value and should be at the top of anyone's list.
This review is from: D-Link DCH-M225 Wi-Fi Audio Extender
Pros: - Obviously the ability to listen to music anywhere is paramount. Otherwise, why buy this? :)
- Easy setup, even in manual mode (see other thoughts below)
- Nice exterior design
- Easy to read/follow instructions
- Had success playing music via various DNLA methods as well as Apple Airplay. All in all everything worked fine for me. I know some have had issues with Android. The app that seemed to work well for me was Streambels AirPlay Chrome DLNA on the Google Play store. Has a nice interface too. Be sure you select the DNLA connection though as it shows multiple ways to connect to it. DNLA was the most stable.
Cons: I would have given this 3 1/2 eggs if I could have and here is why.
First and most importantly: why in the world can't I disable the wireless extender function? I have multiple access points in my house with everything fine tuned and I don't need nor want this function as it only creates extra congestion on the already congested 2.4 GHz band. This should be a no brainer. If someone from DLINK reads this, please consider making this an option. Leaving it on by default is fine for most I suppose, but for those of us who require this option, please give it to us.
Secondly, and this isn't just a complaint to DLINK but to all manufactures out there: please please PLEASE include 5 GHz radios in your products. The 2.4 is congested and slower than that 5 GHz band. I get that for compatibility 2.4 is desired because not all users will have 5 GHz, but if we are to all adopt 5 GHz as we should, we really need to start including it in more and more devices.
Other Thoughts: Ok so here's a bit of instruction for those of you who are complaining about wireless extender speeds. Since this is what I do for a living (IT and wireless deployments), let me impart some wisdom.
2.4 GHz speeds at 20 mhz widths which is the standard is 150 megabit, not 300 megabit. It is POSSIBLE to achieve 300 Megabit on 2.4 with 40 mhz wide channel selections, however due to 2.4 ghz congestion and interference 20 mhz widths or 150 megabit is 99.9% of the time more desirable.
Now that that's out of the way, and we understand that 150 megabit is really what the device is connecting at, here's another thing you should be aware of: when speeds are advertised, pay close attention to the fine print. Because of overhead, interference, and a lot of other technical reasons, wireless connections tend to only achieve about 33% or 1/3 of advertised speeds. That means that a 300 megabit connection maximum expected speeds should be around 100 megabit and 150 megabit connection maximum expected speeds should be about 50 megabit.
Now some of you may be saying, "well hey now, I'm not even getting THAT with my DLINK device on the extender speeds." That is true. So here's the last piece of the puzzle. When you "extend" a wireless signal your speeds will be cut in half. So that 50 megabit that we had before turns into 25 megabit now (sound about right for the speeds you are getting?). This goes for ANY device that extends wireless. This is because now your extender device has to connect to the primary router or a nearby access point and then repeat that signal for you. This creates double the wireless overhead/traffic load.
I hope all of this makes sense. Don't blame DLINK for the poor wireless throughput for extending wireless connections. It's just plain, old radio signal physics. :)
I hope you now realize why before I suggested to DLINK to allow that feature to be turned off. It's much more advantageous to purchase a separate access point or router that has an access point mode (Asus routers do this) and plug it into a dedicated line so you don't have signal degradation. Wireless extenders really should only be used as a last resort.
