My hard drive has been acting slow lately, taking several seconds to load an application. It's the Hitachi HTS723232L9SA62 (7200 RPM). I ran a benchmark and the speeds were in the 70 Megabytes/second range. However, When I open an application (eg. Google Chrome), I run iotop (I use linux) and it says that my hard drive utilization is around 500 Kilobytes/second to 1 Megabyte/second. Sometimes it will peak around 15 Megabytes/second for a few seconds, then drop back to 1-2MB/s. There are not SMART errors.
How is this possible? Why do benchmarks show my hard drive speed as 60 times faster than the speeds I am getting? How is it possible to get speeds this low? This sounds like fragmentation, but I am using linux with and ext2 file system, so fragmentation should be minor or nonexistent. I have over 200GB free out of the 320GB hard drive.
My computer specs
- Thinkpad x61
- Intel Core2Duo 2.00GHz
- 2GB DDR2-667 Memory
- Hitachi HTS723232L9SA62 320GB 7200RPM Internal Hard Drive
Thanks for your help!
