In our computer-dependent world, we are always looking for the next "big thing". Often a new microprocessor from Intel or AMD been. However, in the recent years, the microprocessor is often not the limiting factor in the performance of the computer.

Although hard disk storage capacity has increased significantly in recent years, the access speed remained relatively constant. It is a problem of fundamental importance for the technology. The hard drive is mechanical, and efforts to improve the speed have been diminishing returns.

A technology that competes with the conventional hard disk drive (HDD) is the solid-state drive (SSD). A SSD is not mechanical, it is based on "flash memory", the same computer chip technology used to store pictures with your digital camera. An SSD drive is a novelty only 3 years ago, but no longer.

An SSD can perform better than conventional mechanical hard drives because it smaller and lighter 4X, 50X has faster, more reliable because there is no moving parts, produces less heat and consumes less power. SSD drive is improved memory and 250-gigabyte SSD drives are now available. Currently, the disadvantage is the price.

SSD drives are still more expensive than conventional hard disk. An SSD drive now costs about $ 2 per gigabyte, while a HDD drive costs less than $ 1 per gigabyte. The price of one Continues to improve SSD (SSD drives is sold for more than $ 25 per gigabyte), and the expected production volumes, the price difference should be further reduced.

Flash memory is capable of a finite number of rewrites each memory cell (as conventional hard disks). Significant improvements in technology have occurred in the past years. In addition, Intel developed "load leveling". This technique ensures that all cells of the memory on the SSD a similar workload. Most SSD manufacturers now using similar techniques. An SSD should last 10 years or more for the average user.

The main reason for the rosy future of SSD, the access speed. A conventional fast HDD access times is equivalent to approximately 5 milliseconds. It sounds fast, but when the microprocessor is capable of millions of instructions per second (MIPS), 5 milliseconds is a bottleneck. SSD can have as few as 100 microsecond access time (50x faster).

An important point when trying to use the SSD speeds the potential bottleneck caused by the interface. There are 3 common interfaces used today with SSD drives.

The SATA interface is the most used interface used for conventional hard disk, but a SATA interface is limited in total throughput, both send and receive, to about 3 Gbps. This may be slow for SSD, allowing the performance failures. Some SSD drives are capable of more than 5 Gbps throughput.

Seagate Technology, in conjunction with AMD, has recently announced the 6-Gbps Serial ATA storage interface, also SATA Revision 3.0, a next-generation technology capable of twice the speed of the fastest SATA interface available today be. This technology was demonstrated for conventional hard drives, but has obvious application to the SSD market.

SAS (Serial Attached SCSI) interface is a alternative. SAS is a point-to-point technology with at least four channels. Each channel throughput of 3 Gbps in each direction (a total of 6 Gbps per channel).

A third alternative is to implement the SSD with a PCI Express interface. A PCI Express interface has unidirectional data paths, and send a given one, each at 2.5 Gbps for a throughput of 5 Gbps.

It is possible to benefit the performance of the SSD technology to maximize a careful selection of the appropriate interface.

Sun Microsystems supports SSD

Sun Microsystems, a leading manufacturer of engineering workstations (very fast computers), is highly predictable committing SSD technology. Sun can be seen as a proxy for the PC industry. If the technology behind Sun on the current price, because the prices down, the technology would logically be used by the mainstream PC user. This pattern of clearance was observed with other new technologies.

Sun said that the SSD technology to add its systems to enhance their performance for I / O-intensive applications. Late last year, Sun launched its Amber Road SSD product line. Amber Road is Sun's new line of data-storage system. The Amber Road sells products exceptionally well.

Raymond Austin, group product manager for senior management at Sun said:

SSD technology helps customers to achieve up to 65 times faster response times to eight times better throughput and up to 38 percent less energy than traditional spinning hard drives servers.

An SSD drive will be more tolerant of heavy domestic environments and will be more reliable. Computers using SSD drives will experience faster application load times and better overall performance. An SSD drive can emulate a traditional mechanical hard disk drive (HDD). This makes the replacement of the traditional HDD for a SSD in your current system less complicated. A SSD is probably in your future, the question is when.
