Every time technology progresses, we are confronted with the challenging task of choosing between the old and the new. In the current scenario, we can see that happening in data storage technology. Not long ago, most laptops/PCs had HDD (Hard Disk Drive). But now, more and more computers are being equipped with SSD (Solid State Drive). For external data storage also, consumers are being tasked to choose between HDD and SSD. So, which one should you buy? Well, here are some insights on HDD vs. SSD that will help you pick the one most appropriate for your specific needs.
Size: HDDs have mechanical, moving parts, so they are naturally bulkier than SSDs. If you have seen ultra slim laptops, these devices will most probably have SSDs. If you are looking for improved mobility and less weight, you should go for SSD.
Storage capacity: Both HDDs and SSDs are available in varying storage capacities of 128 GB, 256 GB, 500 GB, 1 TB, 2 TB, etc. The only concern could be pricing, as higher capacity SSDs are quite expensive.
Performance: This is where SSDs really prove that HDDs may have become outdated. SSDs are much faster than HDDs, as they don’t have mechanical parts. While data copying speed of HDD is in the range of 30-150 MB per second, SSDs can do it much faster at around 500 MB/s. Advanced NVMe (Non-Volatile Memory Express) SSDs are even faster, with data moving speeds of 3 – 3.5 GB per second. SSDs are also better when it comes to accessing small files on your computer, as is done by the operating system and software programs. SSDs can significantly improve the performance of your computer.
Power consumption: As SSDs don’t have moving parts, they consume a lot less power. You can have higher battery life if you choose a laptop with SSD.
Lifespan: Both HDDs and SSDs can last for years without giving problems. However, none of these are designed to last a lifetime. So, it’s always better to back up your data at multiple locations.
Durability: With their moving parts, HDDs face an increased risk of damage. On the other hand, SSDs are better equipped to handle shocks and vibrations up to a certain level.
Price: SSDs are certainly better than HDDs, but their high pricing remains a constraint. Price of a SSD is around 2-3 times that of an HDD. However, prices are expected to come down, as demand and production increases with time. You can also choose a hybrid machine, one that has SSD for operating system and programs and a standard HDD for your data such as documents, audio, video, etc.
