4 To a disk for approximately €259 Hitachi

Hitachi out of its hood 4 To HDD...

While the hard disk industry begins to slowly regain with the resumption of production in some plants back to dry after the terrible floods in Thailand, Hitachi GST (in phase of redemption by Western Digital) ends the year on a good note by announcing its first 4 To format 3.5 "disk. Called HDS5C4040ALE630 in all simplicity, it will integrate logically the Deskstar 5 K range.

For the moment, this disk is available to the Japan for a sale price of 26.800 yen, or about 259 euros. It is almost given given rates currently found at specialty retailers... This 4 To disk can count on a memory of 32 MB cache, SATA 6 Gbps interface and operates technology CoolSpin for trays (probably four) operating at 5400 tr / mn. A 7200 RPM version would already be in preparation for 2012.

7 K 1000.D: Hitachi 1 TB per platter passes

Hitachi is still evolving its hard drives of 1 TB. In 2007, the 7 K 1000 was the first hard disk of 1 TB, with a design to five trays (200 GB each, therefore). Then, the 7 K 1000 has evolved to version.(B) and its three 333 GB platters then towards a model.C with only two 500 GB platters. And the company, recently acquired by Western Digital, now offers a version.(D) the disk hard in question, with a single shelf of 1 TB.

Should gain in throughput (227 announced MB/s), consumer (announced 15% gain) and noise are expected to decrease. With such trays, Hitachi GST could even offer hard drives of 4 or 5 To quite easily. For capacity, if 1 TB is the maximum, 250 versions, 320, 500 and 750 GB are planned, with a portion of the plateau which will not be used and a necessarily mean flow a little more high, even if the maximum flow does not move.

The company offers also 5 K 1000.(B), a hard disk with the same 1 To plateau, the successor to the 5 K 1000 classic and two trays of 500 GB. He uses for his 23% energy in less than the 7 K 1000.(D) through its rotational speed of 5400 RPM instead of 7 200 rpm. Flows vary too much, with maximum of 180 MB/s on the 5 K 1000.(B), which is very correct.

The 7 K 1000.D and the 5 K 1000.(B) will be proposed in interface SATA 6 GB/s (maximum 600 MB/S), will offer 32 MB cache and will work with sectors of 4 KB instead of the traditional sectors of 512 bytes, even if an internal emulation is provided.

Finally, note that these disks Cinemastar variants are expected at the same time as versions Desktar, in the fall.

Also 4 To Hitachi!

The Japanese manufacturer Hitachi Unveils 4TB external storage via its subsidiary G-Technology.

Hitachi has announced, through its subsidiary G-Technology and in the wake of Seagate, a 4TB external storage solution. This G-DRIVE is likely to incorporate a hard disk with four trays of 1 TB. Its speed of rotation would be of 7200 revolutions per minute, which would guarantee a good level of performance. G Technology also launches a version of 8 To (with two HDD), named G-RAID (logically configured in RAID-0).

Both models have an aluminum shell, and a triple connectivity, with a 3 Gbps, a FireWire 800 port, eSATA port and a USB 2.0 port. It is unfortunately not known when and how much the Japanese manufacturer account propose these new solutions. G - Technology should also start in the fourth quarter G-RAID and G-DRIVE equipped with a Thunderbolt (10 Gb/s) interface.

New SSD in MLC Hitachi

The Japanese manufacturer launches of new flash drives designed around 25 nanometres engraved MLC flash memory...

Hitachi GST, which will soon fall under the fold of Western Digital, continues to develop its range of flash drives. The Japanese manufacturer presents this day its Ultrastar SSD400M. Found with the architecture of the SSD400S, however, the MLC memory in place of the SLC. It is also of a fineness of engraving of 34 nanometers to a fineness of engraving of 25 nm. Hitachi provides always in IMFT (the joint venture between Intel and Micron). The Ultrastar SSD400M adopt a 2.5-inch format and a Serial Attached SCSI (SAS) interface 6 Gb/s.

Hitachi offers two abilities at this time: 200 GB and 400 GB. Performance are still very good, with sequential 495 MB/s read speeds, and 385 MB/s write. The SSD also reach 56 000 IOPS in reading, and 24,000 IOPS in writing. The Ultrastar SSD400M have a two million hours MTBF, and they are covered by a warranty of five years. They are available now, and therefore complement the ultra-complète range of storage of the constructor.
