Best SSD for Performance, Price and Reliability

April 16th, 2012 - A Solid State Drive (SSD) is one of the most beneficial upgrades that can be made to a computer. SSDs are many times faster than the traditional, platter based hard drives that computer users have become accustomed to over the years. A SSD also runs silent, includes no moving parts and draws less power. These advantages make solid state drives ideal for mobile computing where longer battery life is essential. SSD prices are still relatively expensive compared to HDDs, but prices are dropping and have recently dipped below $1 per gig for some models. For many users SSD prices are now low enough to justify installing their operating system on an SSD for increased performance, lower noise levels and greatly reduced load times. Are you having trouble finding a fast SSD that also has good stability and compatibility? Then check out these four SSD models which provide major performance gains and high reliability for the price.

Intel 520 Series

The Intel SSDs in the 520 series feature 25nm MLC NAND and have been upgraded to the SandForce SF-2281 controller (previously Intel used a Marvell controller). Intel SSDs are known for reliability with some of the lowest failure rates in the industry and the 520 series is no different. Intel SSDs undergo extensive testing to ensure stability and compatibility. Intel's reliability combined with the raw performance of the SandForce controller come together in the 520 series to produce one of the fastest, most reliable SSDs to date. The Intel 520 line of SSDs are available in 60GB, 120GB, 180GB, 240GB and 480GB sizes.

Intel 520 Series Specs
	60GB	120GB	180GB	240GB	480GB
Sequential Read	Up to 550 MB/s	Up to 550 MB/s	Up to 550 MB/s	Up to 550 MB/s	Up to 550 MB/s
Sequential Write	Up to 475 MB/s	Up to 400 MB/s	Up to 520 MB/s	Up to 520 MB/s	Up to 520 MB/s
