  • Hard-Drive Roundup June 2010 - Seagate Barracuda XT 2TB

    Seagate Barracuda XT 2TB
    Seagate%u2019s Barracuda XT is really all about one thing, massive capacity. They have created a drive which offers users as much storage as is currently available in the single drive market and in that respect it has achieved its goal.

    Looking closer at the performance and features of the drive it is great to see Seagate being proactive through use of the SATA 6GB/s interface, though in reality mechanical drives in their current form will not achieve read/write speeds which are available on SATA 2. A more useful addition to the drive is 64MB cache which reduces the potential for any bottlenecks within the drive. This results in a product which has some industry leading read/write speeds for a mechanical drive. Users should remember though that as the drive fills performance such as read speed drop significantly as with other mechanical drives.

    For support Seagate offer a 5-Year warranty and consumers can contact them through email and live chat. A customer forum is also available. Finally we have the value aspect, currently the Barracuda XT is priced at a slightly lower level than other 2TB drives and is double the cost of 1TB models which makes the pricing pretty much spot on.

  • Seagate Barracuda XT 2TB Sata 3.0 HDD

    Yes, it has Sata 3.0, but this Seagate gets little benefit from it - and is expensive, to boot.

  • Seagate Barracuda XT 2TB review

    Given the problems that we had in testing, we recommend holding off on SATA 600 for the time being.

    • Huge...
    • ...and quick with it


    • New interface does little
    • Ridiculously expensive

    Too costly for a 2TB drive and the new interface simply doesn't make up for it"

  • Seagate Barracuda XT 2TB SATA 6 Gbit/s Hard Drive Performance Review

    Conclusion  Seagate wasn't the first to market with a 2 terabyte desktop drive, but they did manage to pull off the first and at this time only SATA 6 GB/s drive.  On one hand this is a big feat for the company, but on the other being the first doesn't always make for a successful product. The good thing is that Seagate has a very fast drive with the Barracuda XT, one of the fastest and quietest platter based drives I have tested. The problem is the rest of the industry is going to have to catch up. At this time LSI and Intel both have SAS / SATA controllers like the one we used today to test with. Promise and Highpoint Technology just announced their controllers today as well. ASUS and GIGABYTE have motherboards in stores or shipping to stores and they will both use a PCIe 2.0 to SATA 6 Gb/s bridge chip to Marvell controller.  ASUS has also told us that they will have a PCIe 2.0 controller card in our hands in the next few days so that will also be an option. These controllers are going to go a long way for users who want to add SATA 6 Gb/s to their existing systems, more importantly enthusiasts that have already chosen their X58 motherboard and who are not looking to downgrade to a P55 based product. These are the types of users who will look to add a SATA 6 Gb/s drive or several in RAID to their systems.  SATA 6 Gb/s with a Seagate Barracuda XT does add some interesting features, but nothing as groundbreaking as NCQ did with SATA 3 Gb/s. Just like the first SATA 1.5 drives, SATA 6 Gb/s will not show major improvements until the drives can really start to break the barriers put in place by the previous generation. Burst speeds will be improved with SATA 6 Gb/s, but how many times will this fraction of a second of performance increase really add to the user experience?  The cost of the Seagate Barracuda XT is really the biggest challenge for enthusiasts and mainstream users. At 299 USD there is a huge price premium over the 5,900 RPM 2TB Seagate drive. Enthusiasts will be ready to take advantage of the additional cache, platter density and increased peak performance from the additional platter rotational speeds but spending nearly double for those is a hard package to sell.

    Seagate Barracuda 2TB Sata 3 (Sata 6Gb/s) (ST32000641AS CC11)

    We took the long hard road on the Barracuda XT and studied and tested it as many ways as we could think of. Since it’s a new interface, on a new drive, it warranted a more through look than say a Sata 2 speed bump drive. We like the Seagate Barracuda XT for a few reasons, mainly we like that it offers good performance on both Sata 3 and Sata 2. In our rational minds we weren’t expecting a major improvement in the speed and Seagate was very up front with that. In our enthusiast minds we saw theoretical speed limits on the new Sata 3 interface. Sometimes you just have to beat the enthusiast side of the brain a little and consider hardware limitations. Given that the Barracuda XT has a pretty standard rotational speed of 7200 RPM, platter density that is the same as most 1 and 2TB Seagate drives, and that drives with those specs are almost maxed out on transfer speeds already we didn’t expect a major speed improvement. What we did expect was a new interface capable of handling higher transfer speeds of drives in the next 3 – 5 years and that’s what we got. Leave it to Seagate to lead the industry and produce the first Sata 3 drive. As technology improves and higher density drives appear the bandwidth that Sata 3 provides may be challenged. Increasing Rotational speed to 10k or even 15k might challenge the bandwidth the interface offers. Certainly high end SSD’s in RAID configurations will challenge it now. The design and concept of the Interface is a design aimed at the future and current platter drives in single drive operation aren’t going to challenge the bandwidth. Now back to the drive itself. (We tend to get excited about new technologies and digress a little) We like the transfer speed the Barracuda XT provides, we like the huge 2TB storage it offers. We love the 64MB cache it has. For all intents and purposes the Barracuda XT is just as Seagate advertised it, a good speed bump, a good speed bump that paves the way for even faster drives down the line. That’s a good thing, speeds might not be as high as we had hoped in our enthusiast minds eye, but in our hardware limitation minds eye it performs just like we expected.

    Seagate Barracuda XT 2 TB Hard Disk Drive Review

    We were expecting Seagate Barracuda XT 2 TB to smash its main competitor, Western Digital Caviar Black 2 TB, because of the use of the new SATA-600 interface, but this didn’t happen: both achieved the same performance level. In fact, Western Digital Caviar Black 2 TB achieved a somewhat lower access time; so if you are looking for a fast 2 TB hard drive, Western Digital Caviar Black 2 TB has a little bit of an advantage.It is very important to have in mind that when a new interface is released this kind of result is not unusual, especially with the very first product. As we have explained in the introduction, the new interface expands the maximum transfer rate the interface can handle, but that doesn’t mean that the hard disk drive itself is faster. It should take a while for us to see drives that can benefit from this new interface. In fact probably SSDs will have greater benefit, as many of them are reaching more than 200 MB/s today, so they may reach the 300 MB/s limit way sooner than hard disk drives.
