Before the launch of Seagate Cheetah 15K.7, very few hard drives were considered reliable for enterprise storage. This has changed altogether with the launch of 600GB Seagate Cheetah 15K.7 SAS Hard Drive ST3600057SS which delivers safe and sound high capacity storage hard drive for enterprise environments.

The specifications of the cheetah 15K.7 are-
The total storage capacity is about 600 GB which reduces the storage cost per GB and increases the capacity per watt, cache – 16 MB; interface is 6-Gb/s SAS. The spindle speed is 15000 RPM, with average latency of 2.0 msec. the random read seek time is 3.4 msec, random write seek time is 3.9 sec. the height of the hard drive is around 26.10 mm, length is 146.99 mm, and is 800 grams heavy.

It is often prescribed that Western Digital's Raptor is the perfect desktop hard drive for persons looking for a performance enhanced ambitions. Ever since western digital introduced the Raptor, it is known as the 3.5" desktop hard drive that spins at 10,000 RPM, and has eaten up the market of other 3.5” serial hard drives in the desktop space.

WD1500ADFD Raptor was released by western digital in January 2006 and features two 75 GB platters, which adds up to 150 GB. The WD1500ADFD Raptor consists of a more advanced system of native command queuing (NCQ). Hence due to this technology the Raptor is capable to increase the performance of SATA hard disks under certain situations.

As with the Radeon HD 4870 X2, the 4850 X2 is a dual designed chip 3D card. Powered by two Radeon HD 4850 GPUs, the X2 version is effectively a self-contained Crossfire setup. It only needed to be connected by this card directly to your PC power supply via one six-pin and one eight-pin PCI Express power input and as a double-wide card, considering a fair amount of space inside your PC. Designed by SAPPHIRE for the new HD 4850 X2 comprises two complete HD 4850 graphics systems on a single PCI-Express card connected by an on-board PCI Express Gen 2 bridge chip, each GPU having 800 stream process units and a 256-bit memory interface driving 1GB of GDDR3 memory, making a total of 2GB on-board memory.

Like most of graphic cards, the EVGA GeForce GTX 260 Core 216 Super clocked is a double-wide card that connects directly to your PC's power supply, in such case via two six-pin PCI Express power connectors are required Unlike the midrange card from ATI, Radeon HD 4850 X2, competing  for, this EVGA card has only a single 3D chip. The only NVIDIA dual chip card has very high end GeForce GTX 295, but it's certainly not the most affordable product out there, nor is it appropriate for those of with smaller monitors. According to the charts, regardless of the number of GPUs onboard, the GTX 260 Core 216 isn't quite up to par with the other cards at or around this price otherwise from the same edition EVGA's Superclocked edition of NVIDIA’s GeForce GTX 9800+ is a fast 3D graphics card is better option to have with an affordable price.
