Seagate is one of the largest and most well-known hard drive manufacturers around, but later this year some of its products are getting retired. The company recently announced it is ceasing production on all 7200RPM 2.5" hard drives by the end of 2013. Seagate will still offer 5400RPM 2.5" drives, but the 7200RPM models no longer make sense as the market shifts to alternatives products. Solid-state drives and solid-state hybrid drives (SSHD) offer far greater performance over a 7200RPM drive, which is something Seagate has noticed. Its third-generation SSHDs are set to arrive later this year, and is what Seagate will promote to users wanting the speed of an SSD yet the capacity of an HDD.
Even though Seagate won't be making any more 7200RPM 2.5" HDDs once the year ends, there should still be plenty of stock to go around for a while after. It may be a good idea to stock up at that point.
