A new milestone in computing has been achieved simultaneously by two companies, Seagate and HGST. It is a single hard disk but offers a mind-boggling storage capacity of 6 TB. The previous capacity that was offered by a 3.5-inch hard disk was 4 TB. So, the increment achieved is almost 50%.
The product is aimed at Enterprise customers and is priced at US $ 664. The high price of the product is understandable as lot of research costs were involved. The economies of scale are yet to be provided by the manufacturing efforts.Storage technology has come a long way and the hard disks are no longer the hottest of all technologies. The drive is both fast as well as high capacity. In fact, it has high sequential speed along with a respectable access time.
But, the assuring fact is that these 6 TB drives will not stay in the same high price range for a long time. They can replace an array of individual disks with just one drive. Another way is to simply add a whole lot of capacity for the NAS or the desktop PC.This 3.5 HDD V.4 is also available in smaller sizes of 5 TB. The features offered are many like spinning capacity of 7200 RPM and also 128 MB of Cache. The rating for the Power Consumption is at 6.9w idle, with 11.27w being usable.
The consumption of power depends on the capacity of the drive and the also on the number of platters. The physical sectors are 4 KB and not 512 bytes and this means greater efficiency while dealing with larger files.
The high capacity is achieved with the help of accessibility of bulk storage of unstructured data, but the performance is not sacrificed. Some of the advantages are:
The service level agreements are met with the 25 % boost in performance levels
It is optimised for a 24 x 7 environment, based on an eight generation platform
Lowering of the TCO, with the high capacity drive meeting the data growth
Bulk data storage is achieved with the Self-Encrypting Drive (SED) technology
The encryption feature of the built-in drive is worthy of mentioning. This is as per level 2 FIPS 140-2 validation. This ensures a secure erase function, when Seagate’s Seatools Windows software is used along with the drive. However, this erase function will not wipe the data like secure erase on SSD. However, the encryption key is changed. When this is used with other data wiping tools like multi-pass overwriting, it can be an effective way for the IT administrators, for ensuring that the data is inaccessible.
The unstructured data storage forms the foundation for the maximum density servers and storage solutions. It is supportive of highest density storage for a greater level of return-on-investment. The protection of the data is done on the drive. The choice is between the SED FIPS 140-2 option and SED models with Seagate. The drive also has 12 Gb/second SAS and SATA 6 Gb/second interfaces for the achieving easier integration.
