How To Choose a Portable Hard Drive?

how to choose a portable hard drive?

As a medium suitable for storing data for various users, portable hard drive is easy to carry, secure, small in size, and large in capacity. If you are looking to buy a portable hard drive, to better choose the device, here are several factors that need to be considered for you:

Type of Hard Drive

There are two types of portable hard drives on the market: mechanical hard drives (HDD) and solid-state drives (SSDs).

Mechanical hard drives store data on disks. It reads/writes data through the rotating disks and the moving read/write heads. Due to the presence of mechanical components, mechanical hard drives are sensitive to vibration, impact, and movement. When using a mechanical hard drive, it is important to avoid subjecting it to intense vibration or impact, to prevent damage to the internal mechanical components and ensure data integrity and reliability.

Solid-state drives use flash memory technology to store data in non-volatile flash chips. Therefore, SSDs generally have longer lifespans and can withstand more write operations without performance degradation. SSDs do not have movable mechanical structures, making them more durable than mechanical hard drives.

Thanks to the development of flash memory technology, the file transfer speed of SSDs is much higher than that of mechanical hard drives. Mechanical hard drives generally have a transfer speed of only around 1Gbps, and some enterprise-level mechanical hard drives can reach speeds of up to 2.5Gbps. However, SSDs can easily achieve transfer speeds of 30Gbps and even astonishing speeds of up to 70Gbps.

In general, we recommend purchasing SSDs because its high-speed. Choosing a hard drive type that supports high-speed transfer can greatly improve work efficiency and file processing efficiency.



USB Port Version

    There are several versions of USB ports. USB 2.0 supports a maximum transfer speed of 480Mbps, while USB 3.0 supports a maximum transfer speed of 5Gbps. With technological advancements, a faster transfer protocol called USB 3.2 Gen2 has been introduced, which supports a high-speed transfer rate of 10Gbps. USB 3.2 Gen2*2 is the successor to USB 3.2 Gen2 and it can achieve a maximum transfer speed of 20Gbps.

    All of the above USB versions are backward compatible, so choosing a portable hard drive with the USB 3.2 Gen2*2 interface protocol is a better choice.

    Size and Portability of the Hard Drive

      Traditional mechanical portable hard drives are generally based on 2.5-inch mechanical hard drives with an added external casing. They have a relatively large size and a fixed shape, which is not aesthetically pleasing and not very portable. Since SSDs use flash memory technology and do not have a fixed mechanical structure, they can easily change the appearance of the hard drive and are compact and portable.

      P10 MagSafe portable ssd

      We can be certain that a portable SSD with a USB 3.2 Gen2*2 interface protocol and compact design is currently the best choice for a portable hard drive. Aiffro P10 possesses all the advantages mentioned above, making it an excellent choice for storage devices.Which is the key to improving your efficiency. You will not regret choosing Aiffro P10.
