Types of Computer and Laptop Hard Drives

In this article I will talk about different types of hard disks including flash, SSD, external and internal hard disks. I will cover all aspects of storage media.

The first type is USB flash drive. USB flash devices are similar to regular hard drive except they are small. Some are micro shape while others are regular pin size. USB storage media is very popular at the moment. The reason is the size and portability. Files can easily be transferred from one computer to another. USB flash devices come in only one file format which makes them compatible with PC and Mac computers. These come with a FAT file system. Thumb media comes in different capacities (32 MB to 64GB). USB media are safe devices unlike traditional hard storage whose failure rate is higher. The reason is, these flash devices do not use heads and platters. Thumb flash uses flash memory for data storage.

The next type of storage media is the famous hard drive. Hard drive comes in two basic types, internal and external. Internal hard disks are used inside computers and laptops in order to run the operating systems. External hard disks are externally used with computer systems to store data. External disks connect to computers via a USB cable. External hard disks have two types, desktop and portable. Desktop hard disks are regular while portables are known as 2.5 inch hard (made for portability). Hard disk uses different parts like PCB, heads, platters and spindle motor for operations. These have a long history of failure especially when they are dropped. Although any kind of hard can fail but these traditional disks have fragile heads and that is why if they fail more than flash drives. That is, a little movement can cause serious damage. As a whole these have long life cycle.

In internal there is a new family of media called SSD (solid state Drive). SSD uses memory chip for data storage just like USB flash. These are faster and more reliable but in fact these are slightly less reliable as other at least at the current stage of the technology. These can fail electronically or logically. The life cycle is also short because of the memory chip design. These SSDs come in different capacities. Because SSD are at their early stage, they are very expensive at the moment. The technology needs a lot of improvement. SSD drive memory can disappear with the passage of time. Data recovery from these hard disks is very expensive. These are part of both PCs and Macintosh computers.

The next kind is Raid technology. It’s not really a type of the hard drive. The purpose is to increase performance and storage. Raid arrays consist of more than one (to improve processing speed and to avoid data loss risks) disks. The other form is network disks. These are also called NAS (network access storage). NAS store data over network. Both NAS and Raid use windows and Linux operating systems. Data Recovery process involves changing parts in case of physical damage. The process is usually expensive.

The next type of data storage devices are known as SD cards. An SD card is a small flash chip that is used to store data in portable devices like phones, camcorders, digital cameras. One type is Micro SD card. These cards also use flash memory for data storage. Data recovery process involves both logical and physical recoveries. They come in 4, 8, 16, 32 and 64GB sizes. Micro SD cards have one problem though. These cards easily heats up during the usage and can fail. If micro SD cards fail physically, data recovery is almost impossible.

In this article I have explained about different types of data storage devices like hard, USB and SSD media.

From laptop hard drive data recovery to Raid 5 recovery: Four things any recovery has in Common

No matter whether you have a Raid data recovery problem or a clicking laptop hard drive, hard drives ad also Raid drivers rely on visualisation. Without being able to visualise a drive or driver, it may be much harder for any software program or expert to repair that laptop or do Raid recovery. Did you know that even with Mac data recovery, a professional and many software programs rely on visualisation in order to rebuild drivers and get computers functioning again? This is why if you need support, it may be better to have on-site support to fix Raid 5 recovery issues and other hard drive data problems.

Isn’t on-site support and off-site support essentially the same service, except technicians do not appear to physical fix the problem? This may depend on what is stipulated in the contract that any business owner or customer signed. Not all support programs are the same, even if they are both off-site support and rely on visualization. While on-site techs may have a higher success rate in fixing and replacing hardware, off-site technicians may score better marks in faster service delivery and offering more timely results. However, some companies that may not want to use off-site data recovery support, but not have the capital or really need on-site support may want to consider managed IT support as a third option. This allows customers to pay only when they use data support technicians. It also may be a better option for companies that don’t want to hire and keep an expert on-staff to handle laptop hard drive data recovery or Raid system problems.

Failing drivers may show same signs, but recovery efforts may not be Similar

Some signs of a failed drive really are universal. If a driver starts clicking or is transmitted a virus, it can spell trouble. Whether it is a laptop or Raid system, it still means an individual or company needs data recovery. Did you know that businesses spend at least £18.3 million a year because they have lost sensitive data? However, not all software programs are effective in retrieving data lost on each computer system, the same. Did you know that some software programs only work with drivers of specific systems, such as FAT, FAT 32, and NTFS? This is why businesses and individuals may want to ask data recovery specialists is they have to tools necessary to handle Raid 5 recovery or Raid recovery in general. Another thing any computer owner or network provider should keep in mind is that most computers use some sort of storage system and mirroring to recreate files that are corrupted. Whether you are using a Raid system or have a single laptop,

Any computer, whether it is communicating with a network or using a Raid array, may need a parity drive or at very least some parity on their machine. What is parity? It is a system pf checking whether data has been successfully transmitted from computer to computer or computer to a Raid array. However, no matter whether a laptop or a network of machines, computer owners should stop using any laptop or system when an error has been discovered and stop saving programs or accessing a failed drive. The risk of transmitting a virus may be too great and a file may not save correctly on any machine whose hard drive or Raid system is compromised. It also may keep efforts from being successful later, when a technician tries to recover data.

Oxford Data Recovery has been helping customers all over the UK recover from data disasters, such as Raid 0, Raid 1 and Raid 5 server failures from manufacturers such as Dell, Microsoft, HP, Compaq, IBM, and more for years. Our rapid raid data recovery knowledge is second to none and we believe we have the best Raid 5 experts in the UK. We offer a free diagnosis and no obligation quote.
