Hybrid Seagate Hard Drive Has Performance Issues
EconolineCrush writes "The launch of Seagate's Momentus XT hard drive was discussed here last week, and for good reason. While not the first hybrid hard drive on the market, the XT is the only one that sheds the Windows ReadyDrive scheme for an OS-independent approach Seagate calls Adaptive Memory. While early coverage of the XT was largely positive, more detailed analysis reveals a number of performance issues, including poor sequential read throughput and an apparent problem with command queuing. In a number of tests, the XT is actually slower than Seagate's year-old Momentus 7200.4, a drive that costs $40 less."
The drives are fine, it's just a firmware issue. They'll fix it in the next few months. It's not like people who bought the drives are screwed because of faulty equipment.
If there's one thing I've learned with Seagate, it's that they're terrible at fixing firmware issues. Their 500GB hard drives for laptops were notorious for having issues caused by crappy firmware that never got resolved by the time I trashed mine.
The caching and everything is all happening at a level below the OS and the file system, but these tests seem to have all been run in Windows 7 Ultimate x64, whatever that is.
Would another file system (ext4, for example) on Linux/*BSD or HFS+ on Mac OS yield different results, I wonder, w/and w/o swap? Can there be clashing optimization techniques here?
