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.
