If you want to take - then the external hard drive has become important for you. But just like internal hard drives, there are many terms for external hard drives that you need to know before you buy it. From this article you will learn what is external hard, why it is necessary to use, and what things need to be well known before buying it.
External hard drive
Speaking of, what is an external hard drive ঙ্গে in this context; Surely this is a hard drive just like a normal hard drive. Because it is portable and usually located outside the computer, it is called an external hard drive. Like ordinary hard drives, it has two types, HDD and SSD (Solid State Drive). Modern portable drives do not require a separate power supply, data can only be used for power. But there are some drives that need to have separate power input, usually they have AC wall connection like laptop.
If you think otherwise, portable hard drives are just like fixed hard drives, just put it out, it can be worked out, it can be opened at the end of work, it has its own protection casing, and you can use hard drive enclosure if you want to make portable hard drive internally hard. Can be used as a drive. If we talk about the connection type of external drives, then there are many types of drives. Most drives run on USB, maybe USB 2.0 or 3.0. Many of today's modern drives feature USB Type-C connectors, as well as FireWire, eSATA, or wireless connectors.
External drives are also called portable drives. You must use a flash drive (pen drive) - it is the smallest portable drive.
Why an external hard drive?
There are many reasons, but if the real purpose is to disclose - see, data is a very valuable thing. And just one copy of the valuable data is nothing but complete nonsense. Hard drives can crash at any time, data can be corrupted, and your data can be stolen along with the hard drive. It is a different matter if you keep online data backup, but I always ask you to back up important data offline, because there is a special question mark about how secure your personal data is in the cloud.
Now when it comes to offline backups, there are many options, such as CDs, DVDs, pen drives — but if your data volume is large and you want to access that data very quickly, the most hassle-free method is the external hard drive. Drive. Not just backups, as well as many types of uses. External drives are ideal for carrying large amounts of data or loading music, movie and software collections from your friend's PC to your PC, compressing and storing necessary and hidden photos and video footage, and thousands more. Maybe.
When it comes to laptops, where changing the hard drive can be a hassle, or you don't want to open the laptop, then of course a portable drive is the best approach. It is possible to create a network storage device using an external drive, where it is possible to access this drive from all types of devices connected to a local network.
Before buying an external hard drive
So now you must know the reasons for buying a portable drive, maybe you have decided to buy a portable hard drive! But there are many terms associated with buying, which can easily confuse you. What type of connector do you need, how much capacity is required, how much portability is required, what will be the speed of any drive — etc. It is necessary to know your details about many terms, so let's discuss all these issues in detail.
Type
As mentioned above, like normal internal drives, portable drives are mainly of two types, HDD (Hard Drive) and SSD (Solid Test Drive). So which type will you deal with? You must know that solid state drives are much faster and more efficient than ordinary mechanical drives. Almost any data instant access is possible as there are no moving parts. But in terms of price and capacity, hard drives will be much cheaper. Mechanical hard drives can easily get up to a few terabytes on a single drive, where buying a 1 terabyte solid state can cost about 3 times more. If you need ultra fast speed then it is best to invest money in SSD, if you want to get it with lots of capacity and low price, then HDD is best. If you travel a lot, I would say make sure to check if your drive has extra shock protection.
Size
Size is an important term when buying any storage media device. However, how big or small capacity you choose depends on your data storage needs. If you just want to back up important data and if they are not too large then 250-350 GB space will be enough for you. If you want to store movies and music or large files, you can buy a few terabyte drives starting from 1 terabyte. Many people have a special habit of downloading, and the bigger the drive for them, the less.
Speed
In the case of drives, speed refers to the amount of data that can be read or written on the drive in seconds. If you are a Windows user, USB or USB Type-C connector is definitely best for you. Normal drives are USB 2.0, but current drives use the USB 3.0 standard, which makes it possible to get a lot of fast connection speeds. If you are a Mac user, you may want to look into FireWire or Thunderbolt connectors. But I would say USB will be more universal in all cases. If you want to transfer files of large size to portable drive, then eSATA connector will be best, it will get a lot of fast speed.
Network drive
If you are that type of person, preferring wireless to everything, then Network Attached Storage (NAS) or RAID solution is best for you. NAS and RAID are especially used to handle large amounts of data. Here you will have to back up data of many computers at once. This setup may not be necessary for a single person, but it is necessary for the office or for a big data backup plan. In a RAID system, you can use a large number of external drives to create a huge data backup center, especially if you need 15-20 terabytes or more. Moreover, by connecting the drive with NAS, you will be able to easily access your external drive using WiFi or any device from the local network.
Remember, backing up data is a very important task. Better solution is to buy an external hard drive without spending thousands of rupees on the data recovery company after the necessary data is lost!
