WD 1TB HDD?

I am scanning my WD 1TB System Drive, a lot of HDD blocks are measuring the access time of <150MS and there are quite a few measuring <500MS. I am not sure what to do with this HDD, shall I replace it now or is it still healthy?

Update:

I am using Crystal Disk Info, however I have had two HDD fail in very close proximity, SMART wasn’t very useful then.

Update 2:

I have everything backed up to a NAS, then to my USB stick and then to my working external SSD. It has 2 red blocks measuring over > 500MS now.

    why not get an SSD? then you don't need to worry about blocks and speed, as access times improve exponentially!

    Hard block access times are not a reliable way of measuring disk failures. The best solution is to have regular backups

    What software are you using? Try Crystal disk Mark. It can tell you how much of your hard disk is damaged so you can make a better decision on whether to replace it already or not.

    Depends on what the "block" consists of as far as file format, etc. are, and the size.  Not all files open at the same rate.  It's the same with any file it all depends upon what you've got your machine running/doing at the time you try to open the file(s).

    Yes, Replace it now while you can still get your files off of it.

    Replace it with a Solid State Hard Drive (SSD).  Then you won't have those issues.
