NIce article although the author doesnt seem to know that there are two measures of a disks performance
1) Throughput - measured in MBytes/sec
2) Bandwidth - Measured in IOPS

These two measures are mutually linked ie 100MB/s can either be 1*IOPS*100MB, or 100*IOPS*1MB

The figures seem to also show a lot of cache effects, or have dubious provenance,  otherwise how does a USB connected drive achieve 2289.5 IOPS (how do you get .5 of an IOPS anyhow)

Hi Gerald,

I do understand there are several things to take into consideration when measuring the performance of any hard drive, however going into depth in so far as eliminating cache effects would go beyond the scope of what this article is attempting to achieve. You may have also noticed that I didn't mention or talk about the effect FSB speeds can have on a hard drive's performance either?

As I mentioned at the start of the article;
The reason you might want to skip the QD32 tests is that they're not particularly useful for real life scenarios and just take additional time to run. QD stands for "Queue Depth" so the software also measures "separate thread" transfer speeds. Information not of much use for our purposes. I only include the results that I got below for the sake of completeness.
I think the general flow of the article from that point forward clearly shows it is targeting beginners to hard disk performance measuring and not representing any type of advanced hard drive performance analysis.  
The figures seem to also show a lot of cache effects, or have dubious provenance, otherwise how does a USB connected drive achieve 2289.5 IOPS (how do you get .5 of an IOPS anyhow)

Indeed.  How do you get a .5 of an IOPS ?  

Or even a .7 or .8  

How about you tell us?  :-)

Thanks for your feedback.  Always great to hear back from ones readers.

Best regards,
Andrew

I had a somewhat similar situation. I built my computer, ordered parts off Newegg. Included was a nice graphics card, my first one. I kept fiddling with the monitor wondering why it wasn't displaying. After awhile, I realized the monitor was hooked to the mother board, instead it needed to be hooked to the new graphics card. lesson learned.

The Eight Noble Truths of Backup and Recovery
LVL 4
The Eight Noble Truths of Backup and Recovery

How can IT departments tackle the challenges of a Big Data world? This white paper provides a roadmap to success and helps companies ensure that all their data is safe and secure, no matter if it resides on-premise with physical or virtual machines or in the cloud.

We recently endured a series of broadcast storms that caused our ISP to shut us down for brief periods of time. After going through a multitude of tests, we determined that the issue was related to Intel NIC drivers on some new HP desktop computers we'd recently purchased.

The Problem

The broadcast storm would occur if the desktop PC went into sleep mode for an extended period of time. We had one PC push out several gigs of network traffic in a matter of seconds. Strangely, we had eight new PC's all on a configuration bench and all were in sleep mode but only three of them were causing the storm. The randomness of the problem made it that much more difficult to diagnose.

This problem first popped up around a year ago with the Intel i217-LM NIC drivers. Some users on a Cisco message board were suggesting that the solution was to disable IPv6, but this did not work. In fact, we disabled IPv6 across our whole network thinking this would stop the broadcast storms but we got another one the very next day. What's so odd about all this is that you have the leading manufacturer of PC's (HP) using a motherboard with one of the leading manufacturers of NIC drivers (Intel) and all running the world's most popular desktop PC OS (Windows) and the problem stil persists.

The Solution

Upgrading the NIC drivers is the only solution here. However, you can't count on Windows Update to give it to you. This means you nead to visit Intel's site

Amazon Echo


Is it worth it to buy an Echo? In a word, yes! For me it was definitely worth it. I use mine on a daily basis.


Prologue & Privacy


At first, I was very skeptical about the Amazon Echo. In general, I don't like voice assistants. I don't like the idea that someone is always listening. On the other hand, I was already shopping for a bluetooth speaker, so I decided to order an Echo and see how it worked out.

Before I ordered an Echo, I made sure to read up on how it works and how private it is. Fortunately, Amazon has good documentation with examples on how to use it and what actually happens when you do use it. It only listens for the wake up keyword. There is a hardware button to disable the microphone hardware until you turn it back on. After it hears your wake command, it does query their server and record your voice, but the transmissions are encrypted. There is a good reason to save the voice recordings, but more on that later. Fortunately, they let you delete as much of your recorded history as you want. They even include a "1-click delete-everything" functionality. All of this allayed my fears enough that I purchased an Amazon Echo.

Developers take note: Amazon was rewarded with money because their developers documented something well!
 

First Impressions


Once I unboxed the Echo, the setup was instant. All I had to …

Apple Watch

Thanks to luck and dedication (hitting refresh every 5 seconds when the pre-orders were going live at midnight on April 10th) I managed to actually receive an Apple Watch on release day, April 24th. Which means I’ve been using it daily for just over a month now (including a serious test of using it for fitness tracking during a full marathon). Plenty of time to really settle in with it and form some solid impressions.


Quick Summary

The quick, high-level impression: I’m loving it! It’s definitely got a few downsides, but overall, the benefits easily outweigh the cons. It’s not as revolutionary as the original iPhone, but that’s mainly because smartphones at the time were terrible, whereas watches are actually pretty good.

Now that that’s out of the way, let’s dig in a little deeper.


An Extension of my iPhone



I’ve always continued to wear a watch for its “at-a-glance” convenience. And the Apple Watch fills that role perfectly, except for much more than time.
 
I’ve frequently read about how cell phones got people to stop wearing watches, because they could just check the time by looking at their phone. But that always seemed annoying to me. Why would I want to have to dig into my pocket to see what time it is? So even though I had been an early adopter of cell phones, I’ve always continued to wear a watch for its “at-a-glance” convenience. And the Apple Watch fills that role perfectly, except for much more…

Upper back Pain:
My back hurt for months. Upper back, mostly my neck, spine and across my shoulder blades. I was getting headaches too, that felt like they were caused by tension in my shoulders, but now I feel fine! I'm sharing this hoping someone else can benefit.

Diagnosis:
I felt like I was stooping while I sat at my desk at work, the monitors were a bit low with no height adjustment so I was bending forward to look at them which made the pain in my back feel worse.

Health and safety studies suggest that the height of your chair seat is adjusted so when sitting with your feet flat on the floor and your lower legs vertical, your knees bend at roughly 90 degrees so your thighs are horizontal or sloping slightly downward, your back should be vertical and supported by the back of the chair, and the arms of the chair should be raised to the height of your elbows so as to just support your forearms, basically sit up straight.

The page at: http://www.globaltotaloffice.com/ggi_08/adjusting_a_chair.html gives a pretty good description of how to adjust an office chair for comfort, right up until step eleven where you forget all the settings you have made and change it all so it will fit underneath the desk.

All the other desk related instructions are about raising the chair or using a footrest if your feet don't reach the floor. None of them suggest what to do if you are too tall …

I have been focused recently on finding the source(s) of my neck and back pain. A couple of weeks ago I dragged a lectern from the conference room into my office and use it periodically during the day as a standing desk. It helps relieve the neck and back pain, however, my feet and legs start to hurt if I use it too much : (

Another example: I have an unusual tall man's build in that my legs are disproportionately longer than my torso. My commuter car was causing me serious leg pain until I modified the driver's seat rails so I could move the chair three more inches further back than what the manufacturer intended. The pain relief was amazing. Now if I could just extend the steering column so I can comfortably reach the wheel : (

I'm going to modify my office desk ergonomics as a result of this article. My chair does not fit under my desk currently, but it will soon. With my long legs, I might need 6" blocks!!

Thanks for the tips!

This is an excellent article and clearly demonstrates the benefits of having a comfortable seating and monitor position for people who have to sit at a desk for many hours in a row.  Another difficulty arises where the desk is a shared one and the other user, or main user, user is diminutive in stature.

I have to sit at a desk for about 3 or 4 hours to do nightly reports after the work is finished in the warehouse and other areas.  I use the dayshift Manager's desk, and he is fairly small.  I used to be 6' 5" tall but I think I have shrunk to just over 6' 3" over the years.  With the chair raised to a maximum height the arms don't fit under te desk and, to make matters worse, the monitor has never been upgraded from a 15 inch one that the Manager never cleans.  I now have to wear reading glasses and I am convinced that straining to see the screen has accelerated the natural degradation of my eyesight and I often suffer neck and shoulder pain from the seating position if I have had to sit at the desk too long.

I purposefully take very frequent breaks, probably for about 5 or 10 minutes every 20 minutes, during which I walk around and loosen up my neck, shoulders, back, and legs.  I am fortunate that I am able to get away from the desk and that I am not stuck there all night, and I must look rather silly each time I stand up and do a freeform dance along the corridor.  If I was forced to sit there all night I would have insisted on a larger screen and a higher desk, although it would be up to me to reduce my middle-aged paunch so I could pull the chair closer to the desk.

It started not too long ago. It was at first annoying. My keystrokes seemed to be randomly generated, not the ones I typed on the keyboard. For some reason this only happened in certain applications (especially browsers such as IE11, Firefox and Chrome), but not in others and in some applications only when I typed too quickly. What was, I thought, the oddest part of the whole thing was that the characters were random, in that if I held down a key it would generate a succession of characters, all different, one of which would eventually be itself. Odd....

I was immediately suspicious. Could this be malware of some type? Maybe a keylogger? I am fairly strict when it comes to my production machine and what I allow on it. I have multilayered security installed and several protection apps that work together to protect me from all kinds of malware. So what was happening? I scanned with everything under the sun.

  2. Chameleon

SOLUTION!! (when I first typed that it was totally unreadable)

It turns out that one of my security applications, HitmanPro.Alert, has a setting that is called Keystroke Encryption.  It is to protect you from keyloggers. When it is turned off my typing looks like this, but when I turn it on my typing looks like this: ywsrc2utfsbqi8d4mj62a2hsm5 (I typed "my typing looks like this ").  So if you run into this - check to make sure it isn't this app (now owned by Sophos, not Surfright, and called HitmanPro.Alert/cryptoguard/InteruptX)

I recently purchased a Bluetooth headset called the Music Jogger (model BSH10). The control buttons on it look like this:

Music-Jogger-BSH10-buttons.jpg
One of my goals is to use it as the microphone and speakers for Skype calls. In that respect, it works well. However, I also want to be able to answer a Skype call with its Multi-Function Button (MFB), so that I don't have to be sitting at the computer when a call comes in. In that respect, the headset fails.

One possible solution is to configure Skype to answer incoming calls automatically, but I don't like this idea, for two reasons. First, most of the time I am at my computer. In those cases, I may not always want to answer a call – especially when I see CallerID . Second, I may not be at the computer and may not have the headset on, in which case I don't want Skype to answer the call. I could try to remember to enable/disable Skype's automatic answer feature depending on my whereabouts, but that is likely to be error-prone – and a nuisance to boot. The better solution is to configure the MFB to answer a call. Fortunately, there's a way to do this easily – and with free software.

The solution presented in this article should work on many Bluetooth headsets. For example, here's another one from Kinivo (model BTH220) with similar controls (excellent headset – I own this one, too):
