54500 power on hours on a 2nd hand PC. Would you trust it?

Bought a 2nd hand refurb dell i5 3rd generation for use for a friend's office PC from a well known bidding site. There was no COA sticker, and I received 1333mhz ram instead of 1600mhz.

Hard drive seemed noisy and slow. Crystaldiskinfo showed this HDD was a 500gb Hitachi Deskstar 7200rpm made in 2008 on sata 1 (I think). It had around 54500 power on hours and only been powered 55 times when I received it. It wasn't initally recognised, as it somehow changed my bios from AHCI to RAID so I couldn't install windows. Changing it back i put windows 10 trial on it.

SMART showed drive was in good health.

Crystaldiskmark showed:

Sequential Read (Q= 32,T= 1) : 67.710 MB/s
Sequential Write (Q= 32,T= 1) : 67.149 MB/s
Random Read 4KiB (Q= 8,T= 8) : 0.959 MB/s [ 234.1 IOPS]
Random Write 4KiB (Q= 8,T= 8) : 1.103 MB/s [ 269.3 IOPS]
Random Read 4KiB (Q= 32,T= 1) : 0.955 MB/s [ 233.2 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 1.063 MB/s [ 259.5 IOPS]
Random Read 4KiB (Q= 1,T= 1) : 0.444 MB/s [ 108.4 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 1.046 MB/s [ 255.4 IOPS]

So obviously I'm going to use an SSD for windows. Would you:
1. Use it as storage only and backups.
2. Trade it in.
3. Bin it as it's probably failed despite passing SMART

If you going to backup as you should then use it if it's fast enough for you.

With only 55 startups it probably not had a hard life, being on all the time tend to be less harsh on life span than standard daily restarting.

It'll be fine for backup, I have a 10 year old Hitachi Deskstar (probably same model as yours) that's still going strong that has been relegated to being a backup of backups for reference mine has 2701 Power on and 51,225 hours on

I have an even older IDE Deskstar that still works too, the Deskstars are probably the most durable drives to ever be created

Was going to use it as the second drive in the computer and a 120gb SSD as the primary drive, and give it to a friend. Will be storing photos, films, documents etc. Would you trust it for this purpose?

Should be fine as a backup drive you'll maybe write to once a month or less to backup data but I wouldn't use it as main storage that you're constantly reading and writing on

Use it for storage if you don't have enough space, if you do then just put it aside. I don't worry about reliability because all drives can fail if SMART says it's good then just use it without worrying but make sure to keep backups.
