OCZ Core Series Features
The drives feature a durable yet lightweight alloy housing, and because OCZ SSDs have no moving parts, the drives are not prone to damage from common mishandling. Designed for ultimate reliability, these SSDs have an excellent 1.5 million hour mean time before failure (MTBF) ensuring peace of mind over the long term. All Core Series SSD drives come backed a two year warranty and OCZ's legendary service and support.
Overview, Benefits, and Use Cases
Recent advances in Flash memory design and production processes have made Flash the hottest new storage technology. Now, new Flash-based solid-state disk drives, or SSDs, are poised to bring enhanced driver experiences to notebook, server, and enthusiast computers. This paper reviews the SSD architecture and its Flash memory chip, examines the benefits of flash-based SSDs, and lists the potential users of this technology.
Solid State Disk (SSD) Drives are completely interchangeable with industry standard hard disk drives. SSDs conform to the same physical dimensions as hard drives, so they can fit in the standard drive bays and enclosures used by millions of computers. And SSDs use the same Serial ATA (SATA) or IDE interface as hard drives, making them functionally identical. This 100% physical and electrical compatibility and interchangeability with hard drives makes it very easy to design SSDs into systems and storage appliances.
Low Power Consumption
A major disadvantage of hard drives is the amount of power they consume. Most of the power in a hard drive is used by the motor that has to spin the disk. Faster performance in a hard drive requires faster rotational speeds of the disk, up to 10,000 rpm's for high performance hard drives. The SSD offers an enormous advantage over hard drives in power efficiency. Thanks to the lack of motors and to the efficiency of flash IC's, SSDs consume a fraction of the power a conventional hard drive demands. When idle, SSDs use about 95% less power than hard drives; and when active, 50 to 85% less power.
Lower power consumption means less heat produced inside the chassis that needs to be expelled, which results in cooler components and a lighter need for chassis ventilation. And more important, in mobile computing less power means longer battery life. Furthermore, each SSD can save up to 21.9 Kilowatt-Hours of power per year compared to a hard drive, making SSDs the ultimate choice for eco-friendly computing.
Hard drives and flash technology have very different performance characteristics. With Access times in the 10-20ms range, hard drives are very slow to locate data, Flash has the advantage of lightning fast access time, well below 1ms. Therefore, SSDs are far superior to hard drives for small random reads and writes.
Hard drives are relatively fast for burst transfers of large sequential blocks of data. But the fastest SSD drives support even faster sustained read and write speeds than the fastest hard drives. High speed SSDs are the best choice for maximum throughput. Another considerable advantage flash has over hard drives is that they do not suffer from delay waking from sleep mode because with no moving parts, they have no need to spin down like a conventional hard drive.
Core series SSD drives are available in capacities of 32GB, 64GB, and 128GB and deliver incredible 120-143 MB/s 80-93 MB/s read/write speeds and seek times of less than 0.35ms, making the Core series up to 10x as fast on a seek-time basis and up to 40% faster on a R/W basis that the best performing 2.5" HDDs on the market, all while consuming 50% less power.
