KOMPAS.com - The need for computer systems with higher capacities as if chased by the current technological developments. Look, the computer memory chip manufacturers continue to create products that have a higher speed. Simultaneously, the producer of data storage container or a hard disk drive (HDD) also increase the capacity and capability of its products.
Now, the HDD not only appears with large storage capacity, but also has a faster data reading speed. Levels were measured from the rotation speed of the disc in units of RPM HDD (revolutions per minute). The faster the spin the HDD, the amount of data that can be read by reading (head) within specified time more and more.
Generally, the ability to read current data HDD 5400 RPM and 7200 RPM. But, now the HDD manufacturers have started reaching 10 000 RPM speed, even a 15 000 RPM. One of the producers who play in this market is Western Digital (WD). Since last year, they released the product WD VelociRaptor 450 gigabytes (GB) and 600 GB with a speed of 10 000 RPM. SATA-based HDD is specifically designed for blade servers, personal computers (PCs), high-performance, Mac computers, professional workstations, and rack servers.
"Speed 10 000 RPM is the first in the industry so that the WD VelociRaptor popular among companies as well as gamers," teaching Harianto Karim, WD Sales Manager Indonesia. Latest product storage capacity WD VelociRaptor is also two times higher than the previous generation that only up to 300 GB.
According Harianto, supported by 6 Gbps SATA interface with 32 GB capacity buffer memory, high RPM HDD is making the turn moving images in games, multimedia, or film look smooth, not broken. WD VelociRaptor can operate 24 hours seven days a week, aka non-stop and has the active period of up to 1.4 million hours.
Market share is still small recorder Head WD ValociRaptor never touches the disk media. Thus, the risk of head and wear of the recording medium is reduced significantly. HDD is also equipped with a better drive protection during transit. WD claims these products are also environmentally friendly since it designed halogen-free
WD VelociRaptor also available in packs IcePack mounting frame measuring 2.5 inches and 3.5 inches. This makes HD packs stay cold, even though installed in high-performance computers. "We are sure the WD VelociRaptor IcePack with mounting packaging is available on the market in this quarter," Harianto teaching.
Reportedly, this time, is preparing WD HDD 20,000 RPM level. Beginning last February, Seagate also has shipped the latest HDD with the level of 10,000 RPM. His name Savvio 1OK. 2.5-inch HDD size, the size of the WD VelociRaptor, this move by 6 Gpbs SAS interface. Reach 600 GB of storage capacity.
But, until now, the HDD market for PC and server products is still dominated by 5400 RPM and 7200 RPM. One reason, the price is relatively affordable. (Cash / Gloria Haraito, Diade Riva N)
