Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

A leaked Intel roadmap for solid state technology suggests the company is pushing ahead with its plans to introduce new high-end drives based on cutting-edge NAND flash. It's significant for Intel to be adopting 20nm NAND in its highest-end data center products, because of the challenges smaller NAND nodes present in terms of data retention and reliability. Intel introduced 20nm NAND lower in the product stack over a year ago, but apparently has waited till now to bring 20nm to the highest end. Next year, Intel will debut three new drive families -- the SSD Pro 2500 Series (codenamed Temple Star), the DC P3500 Series (Pleasantdale) and the DC P3700 Series (Fultondale).
The Temple Star family uses the M.2 and M.25 form factors, which are meant to replace the older mSATA form factor for ultrabooks and tablets. The M.2 standard allows more space on PCBs for actual NAND storage and can interface with PCIe, SATA, and USB 3.0-attached storage in the same design. This gives manufacturers more flexibility for product design.
The new high-end enterprise drives, meanwhile, will hit 2TB (up from 800GB), ship in 2.5" and add-in card form factors, and offer vastly improved performance. The current DC S3700 series offers 500MBps writes and 460MBps reads. The DC P3700 will increase this to 2800MBps read and 1700MBps writes. The primary difference between the DC P3500 and DC P3700 families appears to be that the P3700 family will use Intel's High Endurance Technology (HET) MLC, while the DC P3500 family sticks with traditional MLC.
There are 10TB platter drives around the corner and 100TB drives at universities being worked on. I have a 24TB NAS that will be 40 before the end of 2014 SSD's can't get cheap enough fast enough. There is the issue of data recovery, TRIM kinda eliminates the ability to recover from a corrupted drive. SSD's will replace platter drives platter drivers in the consumer space before long say '15..
Tape failure typically result in the loss of some hundreds of megabytes of data, while disk failures can cost terabytes. CERN has experienced failure rates 10^6 higher data losses on disk-based data.
Tapes typically last decades, while disk storage is rarely reliable after 5 years.
In 2011, Fujifilm and IBM announced that they had managed to record 29.5 billion bits per square inch with magnetic tape media developed using the BaFe particles and nanotechnologies allowing for an uncompressed tape drive of 35TB. The technology is not expected to be commercially available for at least another decade.
Do u have enough storage with your SSD? How many GB?
My work desktop machine uses 256Gb SSD and that's plenty of space as I don't need to store anything other than work and some music. Currently have around 100Gb free on it.
At home I'm a packrat, I have documents and software and images of old PCs dating back close on 20 years (including a VM of a Windows 3.11 machine) so I have standard SATA drives for that (2 x 2Tb).
So, to answer the OP, YES, HDD will become extinct, as to when.... not for a good few years yet. It'll only really be when the capacity and cost/Gb of SSD drops below that of spinners. Even when SSD replaces spinners I think tape will still be around for long-term backup.
I worked in Seagate before, the processes to make a HDD are so awesome,
many parts require high precision technology, very labor intensive,
need clean room facility.
I hope a simpler product with simpler processes can replace HDD.
