Seagate recently took the wraps off of a new 4TB hard drive. The new drive uses the company's 1TB platters, and the ST4000DM000 uses four 1TB platters. Other characteristics include a 7,200 RPM spindle speed, 64MB cache, and support for the SATA III 6 Gbps interface.
According to the company, the 4TB drive boasts an average read/write data rate of 146MB/s (which is good for a mechanical hard drive), max sustained transfer speed of 180MB/s, and sub-8.5ms and 9.5ms average seek times for read and write operations respectively.
The drive is compatible with Seagate's DiskWizard technology, allowing the full 4TB to be used on legacy operating systems. At 4TB, this drive is perfect for digital pack rats and media enthusiasts.
The 4TB Seagate drive can be found for around $190 USD online for the bare-bones drive, or approximately $205 for retail packaging. You can find more information on the 4TB mechanical hard drive on this Seagate data sheet (PDF) or the drive's product page.
I have to admit that I'm tempted by this, despite not having filled my 2TB drive yet.

Hitachi GST (Global Storage Technologies) today announced that the company is beefing up their product line by moving to 1 TB per platter technology. With an aerial density of 569 Gb/in^2 (569 Gigabits per square inch) for desktop drives, both Deskstar and CinemaStar product lines will be infused with the new platter technology and will range in capacities from 250 GB to 1 TB. We are currently awaiting an update as to whether the lower capacity drives are using older technology or fractions of the 1TB per platter drives, so stay tuned for an update. This will be important for the performance of the lower capacity drives because the improved aerial density of the 1TB per platter technology brings a healthy performance boost over the older technology due to the amount of data that is able to be read at a time.
The Deskstar lineup is for consumers and enthusiasts while the CinemaStar drives are low power drives best suited for A/V work in streaming HD video and/or writing HD streams to the disk. Such applications include security cameras, IPTV, and DVRs. The new Deskstar drives are available for purchase now; however, the CinemaStar hard drives will not be available until later this fall.
The Deskstar drives come in two flavors, the higher performance 7200 RPM 7K1000.D and the low power 5K1000.B hard drives that employ Hitachi’s Coolspin technology. Both models feature 32MB of cache, SATA 3 (6 Gb/s) interfaces, and power savings versus their predecessors. The HVERT and 8th generation power management technology has allowed Hitachi to claim 15% idle power savings on the 7K1000.D. On the other hand, the 5K1000.B sees a 23% idle power savings versus its predecessor.
The CinemaStar drives also employ 32MB of cache and the SATA 3 (6 Gb/s) interface. Hitachi claims that 90% of demand (for AV oriented hard drives) lies in single disk hard drives between 250 GB and 500 Gigabytes in capacity. Just like the Deskstar variants, the CinemaStar lineup is also broken up into faster 7K1000.D and low power, slower spinning 5K1000.B products.
While Hitachi is moving to 1 TB per platter, they are slated to be acquired by Western Digital in Q4 2011. The company will continue to ship the drives until “their logical end of life.” The important bit; however, is that Hitachi GST product warranties will continue to be honored after the acquisition. Have you used Hitachi drives lately, or have you moved on to the larger manufacturers?

Tagged: Hard Drive, Areal Density, 1TB Platter
In an amazing feat of data density, Seagate has once again made a leap to the next level of storage technology unveiling 1 Terabyte per platter drives. WIth an areal density of 625 Gigabytes per square inch, Seagate claims the new drives are capable of storing “virtually countless hours of digital music,” and “1,500 video games.”
The move to 1TB per platter drives is an especially important step for high capacity drives. Current 1TB+ drives are using two 500 GB platters, while current 3TB drives are using either four 750 GB platters in the form of the WD Caviar Green 3 TB that PC Perspective has reviewed here, or the five 600 GB platters. With Seagate’s new technology, they will be able to cut the number of platters in their highest capacity 3 TB drives almost in half. By moving from five platters to three, their drives will run cooler, faster, and with less power draw. Improved areal density also reduces the number of moving parts, and thus decreases the points of failure, even with the inclusion of newer and more sensitive read heads.
The place in the market where this new technology will make the most noticeable difference is in the mobile segment. With just a single platter, mobile users will have close to 1.5 terabytes of internal storage in a two platter drive, or 750 GB in a one platter drive while using less power and being capable of faster reads. This means that road warriors will be able to keep more of their files with them without reducing battery life compared to the current crop of mobile hard drives.
Unfortunately, mobile users will have to wait, as Seagate has only announced 3.5” desktop and external drives. These drives will be branded under both the Seagate Barracuda XT and GoFlex lines respectively.
For desktop users, they can currently expect capacities ranging from 1TB to 3TB drives. In a RAID array, these new lower power and potentially faster drives would make for a great addition to an HD video editing rig. Call me crazy, but I’m going to hold onto my old school 320 GB Seagate drives until I can jump straight to 4 TB. So, where’s my 4 platter, 4TB drive Seagate?
Are you excited about this new platter technology? What would you do with 3 terabytes of storage?
