Here is a complete log of my hard-disk drives (HDD) and SSD drives which I maintain in Google drive. These I use for my home (or my family generic use) as well for my development and test devices as well a part of my home lab. I maintain a detailed log this way to monitor the failure rate of these storage devices. Since it is not just hard-disks which fail unexpectedly even SSDs are prone to fail. And in the case of mSATA and M.2 SSD drives since the board is exposed, it may fail sometimes due to mishandling (such as static) or due to any liquid spills. There are cases SSD may fail due to over-heating too due to various heat generating components at its vicinity.

The other reason I main this log is to also monitor the technological advancements in the storage technology. Its not about when Seagate or Western Digital (WD) or Samsung released their latest high-capacity harddrives or SSDs. Its all about when these new latest drives will become eventually affordable and get commonly used and as well to monitor when the older drive technologies (or capacities) will get obsolete. For example a 1TB 3.5'' internal desktop harddisk is obsolete. Where as one can still find 1TB internal 2.5'' laptop harddrive. But on the other hand a 1TB SSD drive is still quite expensive and the SSD market is not that mature yet to completely replace HDD.

As you can see, I maintain details of the drives which are still in use and are in working condition and the drives which are expired (or in other words failed). But it is important to make a note that the duration between the manufacture date (and purchase date) and expired date has nothing to do much in terms of accessing the drive's reliability. For example my WD Green 1TB WD10EARS 3.5'' drive I rarely used and it failed quite prematurely. It started producing weird disk-errors and S.M.A.R.T. errors and eventually failed to respond completely. I barely used this drive. Later I discovered this drive is quite prone to error and many users as well Backblaze already reported about it.

My first hard-disk I bought is a Seagate 10GB drive when I am studying at college. Ever since I got many hard-drives and these are missing in this log. I just got an idea to main this log quite recently and I started preparing this complete Google drive sheet and populated all my existing hard-drives and SSDs which I have it at my home (and my home lab).

In case if you are interested getting S.M.A.R.T. attributes of your HDD and or SSD drive, here is my video log of the same. You can capture these attributes both via Linux Disks GUI tool as well smartctl command line tool as discussed below:

And in case if you are having issues or some inconsistency (such as file corruption, excess read leatency, etc) you can monitor and detect a failing HDD or SSD in Linux as discussed in my video log below:

Saturday' 13-Mar-2021
Here is my second software development update of TOFFEE-Butterscotch. In the previous update (28-Oct-2016) I discussed about the Alerts, etc. Whereas in my first TOFFEE-Butterscotch news update I have introduced about TOFFEE-Butterscotch research, project specifications, use-cases, etc.

TOFFEE (and TOFFEE-DataCenter) deployment with web-proxy cache ↗
Saturday' 13-Mar-2021
If you want to deploy TOFFEE along with a web-proxy cache (such as Squid Proxy) you can deploy the same as shown below. TOFFEE does not cache files. TOFFEE does packet level network optimization. So if you want caching your web content you can use transparent mode web-proxy cache intercepting your WAN links. A web-proxy may reduce amount of data being processed (optimized) within these TOFFEE devices and so reduce the CPU overheads and improve its performance.

A study on WAN Optimization Techniques ↗
Saturday' 13-Mar-2021
There are various techniques with which one can optimize their WAN Network Data. Any long distance communication can be considered as WAN Network. A decade ago any network connecting two countries, considered as a WAN network, and a network within a city as MAN and soon. But these days in general any long distance communication is considered as WAN Network. Such as your Mobile communication networks, Satellite networks, Space Networks (Deep space networks), Trans-Atlantic cable networks, etc.

Why TOFFEE is forked from TrafficSqueezer ↗
Saturday' 13-Mar-2021
TrafficSqueezer is an open-source WAN Optimization project. TrafficSqueezer is mainly a research project which is started around mid-2006. It is initially started as a research (or prototype) code even before it is officially registered in Sourceforge.net. But this code is just primitive user-space raw socket modules. This is later refined and a pre-alpha version is created. Followed by which Alpha release. This prototype code is moved from user-space to Linux Kernel (Kernel Space) and then the journey begin in terms of making a serious WAN Optimization solution. Once the pre-beta and beta releases are complete the mainstream series is started.

Saturday' 13-Mar-2021
Today I have done a test setup so that I can able to connect my Android Samsung Tab via TOFFEE DataCenter. Below is my complete test topology of my setup. For demo (and research/development) context I configured TOFFEE DataCenter in engineering debug mode. So I do not need two devices for this purpose.

Power consumption of my Home Lab devices for research ↗
Saturday' 13-Mar-2021
Here is my power-consumption measurements of various devices deployed within my home lab. I measured via my kill-a-watt sort of power-meter which is fairly reliable and accurate. I checked its accuracy with various standard load such as Philips LED laps and other constant power-consuming devices to make sure that the power-meter is precise.
