New HD vrs old HD

Recommended Posts

Hi

About a month ago I added a new HD [please see specs in the attachment] and the OS is in the older HD [please see specs in the attachment], If I move the OS to the newer HD will I have read/write differences?

Thanks ;)

Thank u Nodles for the software, assuming that the test is reliable, 4k write and 4k QD 32 write are better in the older HD and I`m not sure what should be the conclusion here.

The software should be pretty reliable, it's used in various HDD/SSD reviews/articles etc. Of course you could run it more than once and calculate the average.

Just tested mine:

First: SSD 128GB

Second: newer 1TB HDD

Third: older 500GB HDD

Still can`t understand why 4k write and 4k QD 32 write are better in the older HD when in MHO and logically it should have been the other way around, and what should I do with that info?

Newer ain't always faster (or better in every field). The results might vary depending of your setup; if AHCI is enabled, which SATA-ports are used, is AHCI drivers installed etc. Both drives seems to be 7200RPM and SATA2?

Also you could close all unnecessary processes and temporarily disable antivirus real-time protection (or use safemode) for better results.

  • 4K – random tiny operations one at a time.
  • 4K QD32 – random tiny operations, but many done at a time.

The newer driver shows 7200rpm the older does not show any in SIW diagnostic prog, the old is SATA2 the new SATA 3

Several days ago I fitted a new 2.0TB SATA III hard drive along side my 2 year old SATA II drive (boot) and decided to spec my drives, results which I found interesting. I also ran CrystalDiskMark on a couple of older drives via USB.

I will be intersted to see what difference there will be when I fit the SATA III HD to my soon to arrive Silverstone DS322B USB 3.0 SATA II/III Dual Bay 3.5" HDD Enclosure.

Thank you to nodles for the suggestion re CrystalDiskMark software.

You can see what happened when I updated my SSD firmware (release notes say better performance):

As you can see, read speeds increased a bit (only Seq & 512K) with new fw, but write speed decreased alot. :D

I guess that the two screen shots were close together in time,

and that you not only changed the firmware but you also reduced your Used Space from 96 GB to 89 GB

 

I believe that TRIM may take some time digesting the 7 GB that was deleted,

and suggest that speed performance may be degraded whilst TRIM is in progress.

About a week between these tests. Yeah there's a bit less space, but I don't think the speed change should be that big.

My friend's test with same SSD, older firmware:

Difference between our 4K QD32 read is huge.
