Comparison Toshiba Canvio Basics 2022 HDTB520EK3AA 2 TB vs Silicon Power Armor A60 SP020TBPHDA60S3K 2 TB

Manufacturer's warranty provided for this model.

In fact, this is the minimum service life promised by the manufacturer, subject to the rules of operation. Most often, the actual service life of the device is much longer than the guaranteed one.

For drives used in a PC (see "Intended use"), 5400 rpm(normal) and 7200 rpm(high) are considered standard speeds. There are also more specific options, including models with the ability to adjust the speed depending on the load. In server HDDs, in turn, higher speeds can be used — 10,000 rpm and even 15,000 rpm.

— Wi-Fi module. The hard drive has its own Wi-Fi module. The Wi-Fi standard was originally created for building wireless computer networks, but can also be used for direct connection to various devices. Disks with this function can be used as network drives — data storages that can be accessed by every network user. They are also useful for smartphones and tablets: the built-in memory of such devices rarely exceeds a couple of tens of gigabytes, and external storage can come in handy. Many Wi-Fi drives are initially optimized for use with portable electronics (and some are even designed for specific popular models), but anyway, you should make sure that the drive and gadget are compatible in advance.

— Shock-resistant body. A housing that protects the hardware of the hard drive from shock and shock. It is undesirable to specifically drop such media, but anyway, they endure falls better than unprotected counterparts. The specific degree of impact protection should be specified separately; the traditional indicator is resistance to falls from a height of 1 – 1.5 m.

— Data encryption. Ensures the security of storing information on the disk: access to encrypted information can only be obtained by someone who knows the password. The encryption module is an integral part of the drive and does not depend on the computer to which it is connected. The ability to encrypt data is critical if you pl...an to write confidential information to discs; this feature is especially useful for portable drives and laptop drives, which are more at risk of theft than fixed systems and their components.

— Built-in USB connector. USB plug provided in the design of the drive itself. Thus, no additional cables, adapters, etc. are required to connect such a disk to the computer's USB port.

— Backup button. A separate button for starting the file backup procedure, located on the case of an external hard drive. When pressed, the important information for the user contained on the disc is automatically copied to a predefined folder. It is worth considering that the backup settings must be manually configured beforehand.

— Energy saving mode. Drives with power save mode, other things being equal, consume less electricity than conventional drives — both during operation and in standby mode. They usually have a low rotational speed (see Spindle speed (rpm)). Reduced power consumption is especially important for laptop drives, as it allows longer battery life.

The presence of a hard drive additional protection against dust and moisture.

This feature is typical for external models (see "Execution") — they are the most susceptible to negative factors. The degree of protection against dust and moisture can be different, it should be specified separately in each case. Nevertheless, additional security anyway has a positive effect on the reliability and durability of the media.

Disc compliance with MIL-STD-810 security standard.

Initially, this is a set of specifications that establishes certain levels of protection for electrical equipment from environmental factors. The standard was developed for testing military equipment for the US Army in order to maintain performance in various adverse conditions. It imposes quite stringent requirements on the test subjects: the level of product resistance to impacts during drops and shakes is checked, vibration tests are carried out, the device is tested in a wide temperature range, in rain, in fog, under the influence of sand, dust, etc. However, the MIL-STD-810 label in "civilian" products does not always mean the highest degree of protection. This is due to the lack of strict regulation of the tests. So, the most ingenious vendors test the tested gadgets literally on one or two points of the programme from an extensive list and often deliberately do not cover which tests were passed. Accordingly, the specific features of such protection remain reliably unknown. The standard has been in force since 1962. Each new version of it is indicated by a letter of the Latin alphabet at the end. The further the letter down the alphabet, the more recent the version of the certificate. Since 2008, the MIL-STD-810G specification has been in force everywhere, and in 2019 a new edition of the MIL-STD-810H standard was approved.

Main material used for external hard drive enclosure (see "Performance").

— Plastic. The most common option. Plastic is light, cheap, quite practical, including has good strength properties. In addition, it allows you to create cases of complex shape and almost any colour.

— Metal. Usually, aluminium-based alloys are used for metal cases, but other options are also found. Anyway, such cases are much stronger than plastic ones, and also have a stylish appearance. On the other hand, in terms of impact protection, this material has no advantages over plastic, but it costs much more, and it can weigh much more (depending on the specific alloy).

— Rubberized. In this case, it usually means an additional external coating of rubber applied to a plastic or metal case. All rubberized cases are classified as shock resistant (see Features/Features) — thanks to their softness and resiliency, this coating provides additional protection against impacts. In addition, this material does not slip in the hands, thereby reducing the risk of dropping the device.

— Leather. Housing made of hard material (metal or plastic, see above) covered with natural or artificial leather. Such a coating plays an exclusively aesthetic role: it gives the hard drive a solid appearance, actually turning the device into a fashion accessory. At the same time, the use of...leather significantly affects the cost; so paying attention to such models is for those for whom the design of the drive is no less important than the functionality.
