Which HDD and SSD are attractive?
What is HDD (hard disk drive)?
HDD stores data or TV show to use in PC and when it is necessary, we take and use.
In late years we record high-resolution programs such as hi-vision or 4K, 8K of TV and think that there is much which opportunities saving photograph image which we photographed with digital camera increase.
We recommend that we choose HDD as standard in capacity and Dimensions of disk to such a person.
Capacity of HDD expresses how long you can record many data by 500GB (gigabyte), unit such as 1TB (terabyte = about 1,000GB). As much as this capacity becomes big, we can save many data. For example, (EP8 time fashion) recording is possible more than - up to about 1,600 time for about 120 hours (DR mode) if 4K broadcast is about 44 hours (DR mode), land-based digital television.
It is smooth and is usable comfortably so that capacity of HDD is big, and free space can afford.
How should we choose HDD?
To HDD mainly using hard disk of 3.5 inches of Dimensions lay, and there are dye cloth using paper patterns type and portable type using hard disk of 2.5 inches of Dimensions.
3.5 inches of Dimensions
Unit price per capacity is low, and large-capacity model is had lineup of. It is convenient for how to use to put in TV recording and decided place. In addition, most models need power supply.
2.5 inches of Dimensions
Dimensions of the body is small and can install at small place. As power supply is unnecessary, it is convenient for case and carrying around that want to let TV and PC rotation be refreshing.
There is thing supplying power supply from USB cable, and there is model who does not need power cable.
When we want to lengthen time for TV picture recording more, it can increase numbers of external hard disk to connect by using USB hub.
How to use varies by Uses, too
Recent HDD becomes the reasonable price that it is easy to relatively purchase in high capacity of TB (terabyte).
We record on hard disk for exclusive use of each family on TV, and what even PC disperses according to backup use and Uses and manages will be good.
How should we choose SSD (solid state disk)?
SSD is used as storage device in the same way as HDD. SSD has a short start time, and there is little electricity consumption and can work quickly, but product unit price is high product than HDD. However, person whom work efficiency is given priority to over should choose SSD.
There are following various merits in SSD.
High-speed start is possible, and the reading and writing speed of data is very fast, too
SSD records data in flash memory by electrical movement. Therefore data access time is largely shorter than HDD, and high-speed data transmission is possible. In addition, there is Features which the reading and writing speed of data is very fast in.
High impulsiveness and vibratility-resistant
As disk drive part which is easy to be damaged by shock and vibration does not exist, we realize high impact-resistant ability and vibration-resistant performance.
Is quiet; small size, light weight, electric power saving
As there are not moving parts such as motors, there is not the noise, and downsizing, lightweighting is possible. In addition, power consumption largely decreases in comparison with HDD, too.
Let's choose what we want to give priority to
You compare each Features and should make selection that matched use.
For example, we cost-cut if not particular about the speed of start time in particular by choosing HDD, and there is way of buying to do, and to improve movement to high-performance CPU instead.
Or we save only data to access frequently in SSD, and there is how to use that other data store to online storage.
You may do how to choose to focus on quietness, rapidity, lightweighting to give work efficiency.
As HDD and how to choose SDD vary according to Uses, we recommend that we judge in spite of being thought what you focus on.
