Which one suits your need better an SSD or HDD
With acceleration in digitization and technology coming to the forefront, adapting to storage solutions to back-up and secure the humongous amount of data has gained pace.
The future of work is no longer an abstract concept. What once seemed a distant prospect has abruptly turned into an everyday reality for all of us struggling to manage work remotely. This has given a sudden rise to the amount of data we create every day on our smartphones, Laptops, PC’s and tablets and security concerns have also been high-up on our priority list. With acceleration in digitization and technology coming to the forefront, adapting to storage solutions to back-up and secure the humongous amount of data has gained pace. However, we find ourselves stuck with a tough choice to choose between a HDD or take the plunge and buy a fast SSD. SSD and HDD are similar in their physical specifications, but they store data very differently and here’s why.
The way each works
A hard disk drive (HDD) uses mechanical platters and a moving read/write head to access data whereas a solid-state drive (SSD) is a faster type of device that stores data on instantly-accessible memory chips. An HDD features spinning magnetic media, often referred to as platters, and read/write heads attached to an arm that accesses data by traversing the platters. Whereas, an SSD uses NAND flash memory or 3D Xpoint media to store data. SSDs do not have any moving parts, and tend to be quieter, lighter, and more durable than their mechanical counterparts.
Speed and capacity
SSDs tend to have higher transfer speeds and lower access times (i.e. latency), which equates to better performance, but also higher cost when compared to an HDD with a similar capacity. For instance, the copying process takes 30-150 MB/s on an HDD, the same action takes about 500 MB/s on an SSD. Thus, coping a 20 GB file on an SSD will be completed in about 10 seconds but can take up to 2 minutes on an HDD. Like SSDs, HDDs vary dramatically in capacity, and it is easy to find relatively affordable HDDs in the 10TB or higher range. This makes them a practical option for people looking for higher capacity over higher speeds. With the new improved models of SSDs, their read and write operations are spread evenly across all cells in order to minimize “cell death.”
All in All
It is suggested to opt for a mixed system with HDD mass storage and an SSD boot drive. This way, you'll get a balance of price, performance, and space, and you'll have a well-rounded machine for all occasions.
WDC offers some of the best internal and external SSD’s that are reliable, cost efficient and offers impeccable performance. If your storage requirements are smaller, an internal SSD solution is the way to go. If you can have an NVMe drive in your PC, then the WD BLACK SN750 NVMe SSD and WD Blue SN550 NVMe SSD is all that you would need to increase performance and speed on your PC. For the best portable storage solution for all your needs the best option would be the SanDisk Extreme Pro SSD.
However, if you're running out of space on your laptop hard drive, or you want to back up your photos and videos, then a portable HDD is all that you need. Available with a storage capacity of upto 5TB, the WD My Passport HDD is the best buy for you. Its combination of solid performance, hardware encryption, and useful utilities makes the 5TB WD My Passport as the best buy for everyday backup of sensitive data or storing a massive collection of videos, photos, and documents.
