Bad SMART info?

My hard drive seems like it's been pretty slow lately so I looked at its SMART info using Speccy. Here are the results:
01 Read Error Rate 200 (200 worst) Data 0000000000
03 Spin-Up Time 140 (139) Data 0000000F76
04 Start/Stop Count 099 (099) Data 0000000596
05 Reallocated Sectors Count 200 (200) Data 0000000000
07 Seek Error Rate 100 (253) Data 0000000000
09 Power-On Hours (POH) 092 (092) Data 0000001995
0A Spin Retry Count 100 (100) Data 0000000000
0B Recalibration Retries 100 (100) Data 0000000000
0C Device Power Cycle Count 099 (099) Data 0000000587
C0 Power-off Retract Count 200 (200) Data 000000004F
C1 Load/Unload Cycle Count 200 (200) Data 0000000547
C2 Temperature 114 (102) Data 000000001D
C4 Reallocation Event Count 200 (200) Data 0000000000
C5 Current Pending Sector Count 200 (200) Data 0000000000
C6 Uncorrectable Sector Count 200 (200) Data 0000000000
C7 UltraDMA CRC Error Count 200 (186) Data 0000000E0A
C8 Write Error Rate / Multi-Zone Error Rate 200 (200) Data 0000000000
Temperature 30 °C
Temperature Range ok (less than 50 °C)
Status Good

I don't know much about this, but from the looks of it my hard drive is performing awfully.
Can someone who's experienced with this tell me what I should do?
