Solid state drives are beginning to find their way into enterprise storage environments, but among storage managers, they are generating as many questions as answers to storage problems. In this FAQ guide, Mark Peters, an analyst with consulting firm Enterprise Strategy Group, provides answers to the questions he is hearing most frequently from storage administrators related to solid state drives. At Enterprise Strategy Group, Mark covers storage systems and storage in the data centers, and also writes a blog called Mark My Words, which he calls “an askance view of what’s amazing, asinine or ahead in storage.” In today’s podcast, Mark is going to let share some of the questions he’s hearing most often about solid state technology

A solid state drive is a storage device that uses solid state memory to store data. While technically not a disk, a solid state drive will often be referred to as a solid state disk drive, or a solid state disk, in reference to the fact that, in some ways, it replaces the traditional hard disk drive.

After many years of being a niche solution, Solid State Disk (SSD) technology for the enterprise is finally gaining some momentum, and the price points are becoming interesting. Like virtualization, SSD technology has been around quite a while, but the current flash memory technologies in the consumer marketplace are gaining immense popularity. The first SSD product that I’m aware of was made by Dataram Corp in 1976 for the mini-computer market

If you've accidentally deleted a file you need, there is hope. While it used to be that deleted file recovery could cost you several hundred dollars, there is a simple new and inexpensive way you can bring those deleted files back to life. When you delete a file from your hard drive, it first does to the recycle bin and then once you go ahead and empty the recycle bin, the file is permanently removed.

Storage capacity is not the only issue when dealing with hard disks.  The rate with which data can be accessed is also becoming an important factor that may also determine the useful life span of magnetic disk-drive technology .  Although the capacity of hard-disk drives is surging by 130 percent annually, access rates are increasing by a comparatively tame 40 percent. To improve on this, manufacturers have been working to increase the rotational speed of drives .  But as a disk spins more quickly, air turbulence and vibration can cause misregistration of the tracks, a problem that could be corrected by the addition of a secondary actuator for every head.  Other possible enhancements include the use of fluid bearings in the motor to replace steel and ceramic ball bearings, which wear and emit noticeably audible noise when platters spin at speeds greater than 10,000 rev. per minute

The Host Protected Area (HPA) as defined is a reserved area on a Hard Disk Drive (HDD).  It was designed to store information in such a way that it cannot be easily modified, changed, or accessed by the user, BIOS, or the OS. This area can contain information ranging from HDD utilities, to diagnostic tools, as well as boot sector code.  An additional hidden area on many of today’s HDDs is the Device Configuration Overlay (DCO).  The DCO allows system vendors to purchase HDDs from different manufacturers with potentially different sizes, and then configure all HDDs to have the same number of sectors.  An example of this would be using DCO to make an 80 Gigabyte HDD appear as a 60 Gigabyte HDD to both the OS and the BIOS

There are several ways in which flash memory can be used as file storage in embedded systems . Three of them are explainedbelow.As implified diagram of components involved in host Operating System (OS) access to a flash file system is shown in figure 3.  As a reference, the situation for a hard disk is shown on the left hand side.

Cheng Du: report from the IT168 on 12th January, the crocodile, data recovery equipment Research and Development corporation, salvationdata, makes its decision to launch more than five million acquisitions or being a shareholder over about ten province level data recovery companies this year, these companies specialized in data recovery business with their professional technologies and good background of big account sales and services in their regions.

Seagate hard drive data recovery cases can be the most popular recovery cases for data recovery companies and the following are some basic but important knowledge for those with access level of seagate data recovery . Seagate Drive Families Two Architectures: U Series and Barracuda U Series: U6, U8, U10, UXX and B540 Barracuda: Barracuda I, II, III, IV, V, U7, Barracuda  7200.7 ( ALPINE, PUMA and  APLUS), U9,  Barracuda 7200.8 (TONKA), Barracuda 7200.9 (TONKA2, TONKA15, TONKA40, TLITE1HD  and  TLITE2HD), Barracuda7200.10 (NHAWK1HD, NHAWK2HD, GALAXY, GALAXY2D, GALAXY3D,  GALAXY4D and NHPLUS2HD), Saturn, Neptune,  MERCURY, MERC2, VENUS, M72, CORSAIR and MLITE Note: The drive family, Maxtor DiamondMax , is Maxtor labeled but based on Seagate technology.

The evolution in consumer electronics has caused an Texponential growth in the amount of mobile digital data . The majority of mobile phones nowadays has a build in camera and is able to record, store, play and forward picture, audio, and video data.
