Unfortunately, Seagates harddrives are pretty much hit or miss.
It seems like yours started failing. If those are really the read- and writespeeds you get, you should definitely replace it. (and use the Seagate as a storage ofc).
If you're going for a new HDD, I'd recommend the Samsung HD103SJ 1TB. Very good and reliable harddrive.
Getting (121.x MB/s read- and 115.x MB/s writespeeds and I have only 250GB/1000GB left)
Did you notice Windows taking longer to boot than usual?
