Understanding RAID Systems: A Comprehensive Guide to RAID 0, 1, 5, 6, and JBOD

A RAID (Redundant Array of Independent Disks) system is a storage virtualization technology that combines multiple physical disks (SATA, SCSI, SAS, or SSD) into a single logical volume, simultaneously providing data protection and performance optimization. It is one of the most cost-effective solutions for securing your data in a professional or home environment.

Depending on the RAID level chosen, this technology allows you to tolerate the failure of one or more disks without data loss. The most common levels—RAID 0, RAID 1, RAID 5, and RAID 6—meet different needs in terms of capacity, speed, and redundancy.

Key point: A RAID system does not replace a backup. It protects against hardware failure, but not against accidental deletion, ransomware, or physical disasters.

Monolith – Memory Card

A 32 GB memory, that is over 256 billion bits of information stored in 1 cm², thanks to electrons trapped in a 'grid'.

The First Ransomware

In order to fraudulently obtain over one billion dollars in 2016, hackers did not hesitate to flood the world with infected emails. More than 40% of global spam contains a ransomware.

Hard disk operation

The precision of a read head is comparable to that of a Boeing 747 flying at 272 km per second, less than a centimeter above the ground, while being able to count every single blade of grass.

Recognizing Counterfeit Memory Cards

A counterfeit memory card operates on the same principle as any other counterfeit product – it resembles another product, but isn't what it appears to be. Many sellers offer simple 8 GB memory cards while claiming they are 64 GB cards. Any data exceeding the actual 8 GB capacity will be lost.

5mm High Hard Drives for 2015

Microprocessor and motherboard manufacturer Intel is working with hard drive manufacturers to standardize a new 2.5" disk format for Ultrabooks. The idea is to reduce the size of hard drives by 28%.

PMR Hard Drives

Since 2006, hard drives have used a technology called PMR (Perpendicular Magnetic Recording) for data recording.

Hard Drives Exceeding 60TB with HAMR Technology

In March 2012, Seagate was the first manufacturer to successfully store more than 1Tb per square inch using HAMR technology.

Hitachi and the 4TB Hard Drive

As announced some time ago, Hitachi has released a 4TB hard drive.
