SSD vs HDD | The differences:

Welcome here, today we will discuss about SSD and HDD.

First let's start with the full form:

SSD: Solid State Drive

HDD: Hard Disk Drive

From the above name, you might have known that these are storing devices. HDD is an old-school storage device where is SSD is a newer and faster type of storage device.

HDD uses mechanical platters i.e; a moving reader/writer head which helps to access data. Where as, SSD stores data in instantly accessible memory chips like a RAM.

You are here, means that you are likely to buy a new drive (don't get offended if not), so without any delay let's begin our discussion:

Comparison on:	SSD	HDD
1. Price	Comparatively Expensive than HDD 1 TB SSD price in Nepal: Rs. 18,000 or more...	Cheaper than SSD 1 TB HDD price in Nepal: Rs. 8,000 or more...
2. Size	Available between 2.5'' to 1.0"	Available between 3.5" to 2.5"
3. Main Feature	High performance processing and faster access to data.	Long-term storing with high storing capacity on low cost.
4. Read/write speed	200 MB/s to 2,500MB/s	upto 200MB/s
5. File copy speed	200-550 MB/s (Though this may differ)	50-120 MB/s (Though this may differ)
6. File Opening speed	Upto 30% faster than HDD.	Slower than SSD
7. Power Draw	Less power draw (on avg., 2-3 watts)	More power draw (avg., 6-7 watts)
8. Heat	Less heat is evolved as their is no moving part.	High amount of heat that may damage itself due to moving parts.
9. Drawbacks	Not good for long term archival of data. Mayn't be as durable and reliable as HDD.	It is slow as mechanical components take longer time to read/write than SSD.

From the above table, you might have known that SDD is far more better than HDD in terms of quality and data speed, but yeah, SSD is costly. So, if you are buying a new drive or a new laptop, I would recommend you to buy a SSD or the laptop with SSD.

What is a Country? देश भनेकाे के हाे?

Yesterday, on January 13, Nepal's Coat of Arms was updated to add Kalapani and Limpiyadhura as in the new Political map. In this context, we today discuss on what actually 'a country is for it's citizen.' देश भनेकाे के हाे? What is a Country? जनताका लागि देश के हो ? जनताका लागि देश संविधान, कानुन, नागरिकता, सिमाना र झन्डा मात्र हो ? होइन । जनताका लागि देश राजधानी, त्यसबीच ठडिएको दरबार र त्यसको गजुर हो ? होइन । जनताका लागि देश भनेको सरकार हो ? होइन । जनताका लागि देश निर्वाचन क्षेत्र मात्र हो ? हुँदै होइन । त्यसो भए जनताका लागि के हो त देश ? जनताका लागिदेश चार सिमानाभित्रको माटो मात्र होइन । योसँगै जोडिने भावना, प्रेम, ऊर्जा र सपनाहरूको बगैंचा हो । जनताका लागि देश आशा हो । जनताका लागि देश खेतमा झरेको पसिनाको बियाड हो । आन्दोलनहरूमा सडकमा पोखिएको रगत हो । आफ्ना सपनाहरूको कविता हो । जस्तो, एउटा शिशुका लागि आमाको काख । जस्तो, भर्खर हिँड्दै गरेको एउटा बालकका लागि पिताजीको हात । एउटा यात्रीका लागि देश बाटो हो, जसमाथि ऊ आफ्ना पैतालाका डोबहरू छोड्छ र गन्तव्यतिर बढ्छ । देश भनेको ...
