Seagate is at the forefront of the mechanical drive market with the first ever drives to contain 1TB per platter. The the newly re-introduced Barracuda XT drive. We say "re-introduced" because the Barracuda XT 3TB drive that we have here today is actually a new drive, yet Seagate has introduced other drives under the same brand previously. Seagate released Barracuda XT 3TB drive, which we had reviewed back in April. Along with the launching of the first ever 1TB drive, Seagate also announced that the company is streamlining its Barracuda product family. Seagate will kill off the Barracuda Green line, leaving the Barracuda family's focus solely on performance mechanical hard drives. Seagate's own assessment shows that the low-power Barracuda Green hard drives barely save less than a dollar per year in electricity cost, while causing a 20% to 40% performance reduction. Seagate believes the saved power does not compensate for the tradeoff in performance due to lower rotational speed. This moves makes a lot of sense, since SSD's have changed desktop storage: users that need a fast random access drive would be better off choosing an SSD. Mechanical drives serve better as storage drives.
Storage space is something we all need to store the digital content of our lives. Whether it is family portraits, videos from the family vacation, forms, music, the latest movies downloaded straight from sources unknown(Not that we would do that mind you), or spreadsheets that track our monthly expenditures, the need for more storage space continues to rise as we keep more and more of our lives stored digitally. Higher definition digital video recorders and cameras plus high definition video content keep driving the need for storage space up with larger and larger file sizes. Not to mention the fact that most of us are digital hoarders, we keep everything it seems. Hard drive manufacturers seem more than willing to oblige our lust for more and more space. Seagate delivered their largest single drive to date the Barracuda XT ST33000651AS 3 Terabyte drive back in June. That drive had six 500GB platters in it and was a 50% increase in capacity over the previously released Seagate Barracuda XT 2TB drive that debuted back in December of 2009. Technology has a way of marching relentlessly on and just four months into the life cycle of the 3 Terabyte drive, Seagate has improved the breed with a change in platter size from 500GB platters to the industries first drive equipped with 1 Terabyte platters.
Seagate’s Barracuda line has long been a contender in the 7,200rpm drive space and—7200.11 firmware snafu notwithstanding—has generally vied with WD’s Caviar Black line for the 7,200rpm crown. The Barracuda XT 3TB is a five-platter 7,200rpm drive with 6Gb/s SATA and 64MB of cache, just like the Hitachi Deskstar 7K3000. So what’s the difference? Like the Hitachi drive, but unlike WD’s Caviar Green, the Barracuda XT ships sans hardware adapter, instead offering a link to rebranded partitioning software. In this case, Seagate offers the Seagate DiscWizard, powered by Acronis. Again, it doesn’t offer much functionality beyond that provided by Windows, but it is easier for novice users. Those with 64-bit operating systems, UEFI-enabled motherboards, and GPT partitions won’t even need that. In our low-level disk benchmarks, the Seagate Barracuda XT offered sequential read and write speeds exceeding 120MB/s, while random-access times lagged a few milliseconds behind both the Hitachi Deskstar and WD Caviar Green 3TB drives. In Premiere Pro and PCMark Vantage, though, the Barracuda’s scores were slightly slower than those of the Hitachi Deskstar—12 seconds slower in Premiere Pro and around 600 PCMarks (whatever those are) behind the Deskstar.
As the world we live in continues to become digitized, we have to have a way to store the ever increasing amount of data. Digital cameras and video recorders are increasing in resolution and the resulting increase in file size means that the amount of storage space needed to hold onto these files needs to grow right alongside them. Without the increase in capacity, even more devices are needed for storage, increasing power consumption and heat. The 3TB Barracuda XT is a 50% increase in capacity over the first-delivered SATA 6Gb/s 2TB Barracuda XT released last year. The ST33000651AS is deigned for use in high performance systems with its 7200 RPM spindle speed and 64MB cache buffer with a sustained transfer speed of 138 Mb/s, making it a great option in a gaming rig. A spindle-based mechanical drive will not deliver the ultra low response of an SSD, but so far the SSD does not come close to the cost/capacity ratio presented by the traditional disk drive. Currently retailing for $189, the 3TB Barracuda XT offers costs of roughly 6 cents per GB, or just over $60 per terabyte of capacity. With the introduction of this drive, Seagate offers up a solution to addressing the 2TB storage limitations present in legacy operating systems and hardware with the latest revision of its DiscWizard software.
Desktop storage has been stuck at 2TB for quite a while. Higher platter density is needed in order to break the 3TB barrier, which leads to the industry-wide adaptation of 4K advanced format, replacing the 512 sector that was introduced back in the 80's. The truth is, hard drive manufacturers are more than capable of making 3TB drives even with the 512 sector. However, we have not seen these drives appear on the market until most recently. The reason behind it is the aging BIOS chips that are unable to recognize and boot off a disk that is larger than 2TB. In order for a system to boot off a 3TB drive as primary drive, a motherboard must support the new UEFI BIOS. Currently, there are only a handful of motherboards on the market, such as the ASUS P8P67 and the Intel P67 board, that support UEFI BIOS. While some motherboard manufacturers, such as GIGABYTE, found a workaround on their boards without the UEFI BIOS, on most older boards, it is impossible to have the board retro-fitted to support the UFEI BIOS so it can recognize the 3TB drive. Thus, probably more than 90% of systems in existence now will not be able to utilize the 3TB drive as primary drive.
