Western Digital RE3 1TB HDD
Hello again. I’m Rodney Reynolds and welcome to another video review. Today, I’m looking at the Western Digital RAID Edition 3 1TerraByte Hard Drive.
Included with each hard drive is a Serial ATA cable, screws for mounting the hard drive and the jumper. The western Digital RAID edition line of 3-inch of Serial ATA hard drives are currently available in capacities ranging from 250gigabytes to 1 terabyte. I’ll be looking at the 1 terabyte model. Before I continue, let me go over what to consider and look for when selecting a 3.5-inch hard drive.
The first decision is whether to go with a single hard drive or multiple hard drives in a RAID configuration. RAID stands for Redundant Array of Independent Disks or Redundant Array of Inexpensive Disks. A single hard drive is inexpensive but will be slower than two hard drive in a RAID 0 configuration. The disadvantage to a RAID 0 setup is if one drive is corrupted all the data is lost. A RAID 5, RAID 10 setup is much more secure but lacks the performance of RAID 0 and since these are RAID edition hard drives they really should be used in a RAID configuration.
There are five main features to consider when selecting 3.5-inch hard drive. Interface, rotation speed, buffer size, access seek time and capacity. There are two interface types IDE and Serial ATA. Select the hard drive with Serial ATA or Serial ATA 2 Interface since it’s the newest technology. The Rotation speed should be 7200 RPMs or greater probably 10,000 RPMs and the buffer size should be 8 megabytes or greater probably 16. Although remember, the 750 gigabyte and the 1 terabyte models have a 32 megabyte buffer size and the average seek time should be less than 10 milliseconds. Also get a hard drive that best suits your storage needs.
This hard drive’s interface is Serial ATA 3 gigabits per second, has a capacity of 1 thousand gigabytes or 1 terabyte. The average seek time is 4.2 millisecond, the rotation speed is 7200 RPMs, it has a buffer size of 32 megabytes, power consumption is 8.4 watts while being accessed and 7.8 watts when idle. The noise level range from 28 decibels to 33 decibels and comes with a five-year warranty. Now let me briefly outline the key technologies of this product. The latest RAID edition drives employ RAID specific time limited, air recovery and this prevents drive fallen cause by the extended hard drive air recovery processes common to desktop drives.
Dual processor means twice the processing power resulting in a 20% performance improvement over the previous generation. Their fourth generation RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time for up to 60% performance improvement in high vibration requirements over the previous generation of drives. It utilizes perpendicular magnetic recording technology to achieve even greater aerial density, reliability and design margin.
Each drive is put through extended burn and testing with thermal cycling to ensure reliable operation and stable track technology which ensures that the motor shaft is secured at both ends to reduce system enduce vibrations and stabalize platters for accurate tracking during read and write operations. Intelliseek technology calculates optimums seek speeds to lower power consumption, noise and vibration. This illustration shows the effect of Intelliseek on power and vibration when computer to a standard seek.
Third Generation dynamic fly height which means each read write head fly height is adjusted in real time for optimum reliability. No touch ramp low technology ensures that the recording head never touches the disk media and these results in significantly less where to recording head and media as well as better drive protection in transit. Let’s have a closer look at this hard drive. Here is the Serial ATA power connection, Serial ATA data connection and the jumpers. On the left side and the right side as well as the bottom are screw holes for mounting the hard drive. At the top is the hard drive model number, serial number, manufacturing date and more information. Note that Western Digital uses multi stage formed stainless steel top covers and precision designed base capacitors at minimized sound levels which is excellent for quiet applications.
While this hard drive performs really well in a single configuration of course it’s best in a RAID configuration it certainly performs exceptionally well in a RAID 0 configurations. If you’re looking for RAID setup this drive is fantastic and there are lots of capacities to choose from. Overall this is a kickass product. Until next time, take care
