Seagate announce the goal to achieve 2TB in Enterprise segment

**Santanio** · 03-02-2009

"Even the American producer reaches the threshold of 2TB on a single unit, but, unlike the competitor decides to allocate this type of product only to the enterprise segment and not to the consumer"

Seagate also announced that it has reached the goal of 2TB of capacity on a single unit.

Unlike what has been done by the direct competitor of all time, Seagate has decided to target the solution to the enterprise market, thus placing the new disc in the family Constellation ES. The new category, which does not arrive before the third quarter of 2009, will be characterized by the presence of solutions of lower denominations, respectively, 500GB and 1TB, in addition to the above 2TB version. All models are 3.5 "and a rotation speed of 7200RPM: You can also choose whether to use a SATA connection 300MB/so by SAS 600MB / s. Only towards the end of the year will be released 2 versions , 5 "Constellation series, characterized by the capacity of 160 and 500GB.

On consumption, all solutions have the Constellation PowerChute function, capable of reducing any dispersion of energy and at the same time optimize consumption.

Seagate has chosen to use a different approach than what has been done by the competitor: developing the new Constellation 2TB has definitely thought about designing a hard disk in a position to represent the ultimate in terms of capacity and the same ing to maintain a certain level of performance. The choices made are thus led to automatic placement of product on the Enterprise. Western Digital, by contrast, has preferred to maintain a competitive cost, reduce the speed at 5400RPM.

Here is how things goes, including mechanical disks increasingly dense and governing SSD throughput ever higher, the controller raid end enterprise will have to adapt if they will be the bottleneck ...

**Pageous** · 03-02-2009

RAID controllers-end "enterprise" (not the policy options "pseudo RAID" based on one of the many "flavors" of Intel ICHxR then) have already been sized.

For example, the controllers of ACT tech. (also available with fiber channel connection to 8Gb / s) or the line feature of LSI Corp. bus pci express X8.
It has already been made to their firmware control to adjust to the SSD (which indeed have other problems ... and reliability in the long long term).
The speed of rotation of the spindle motor in a Winchester hard disk can not be chosen at random.

In light of that should be designed around the aerodynamic system that supports the flying head sliders door.

Today is the standard speed of 4200, 5400, 7200 and 15000 rpm, but in the past, for example in the'80s when they were on the market many manufacturers of hard disk, speed of rotation existed outside of the standards to which we are accustomed today (3873 rpm for example, in some series).

It 'also true that at the time were still used for read heads "magnetic induction", and recording density per square inch, but very much lower than today.
Thank you.
