One thing that was puzzling: it told me that I had a
Western Digital 1TB 7200RPM Hard Drive (Drive form factor: 3.5"). It told me to replace it with a
Crucial MX500 SSD ... which is also 1TB. (Retailing at about $50 USD, which means ...$120 AUD). *headdesk*
Cost aside, why replace one 1TB drive with another 1TB drive? Surely, if I was going to upgrade, I should increase the drive-size? *shrug*
That's a solid state drive (SSD). They are much, much faster than mechanical drives. As goatmeal mentioned above, your mechanical drive might be slowing things down.
To add to what NotBobSmith wrote, if you have the funds, you may want to consider a dual-drive system where the Operating System and programs reside on the SSD, while all your data is on an HDD (which you currently own).
SSD
Pros = Much faster than HDDs ; no mechanical / moving parts
Cons = Higher cost & lower capacities than HDDs ; much shorter lifespan for writing & re-writing than HDDs
HDD
Pros = Much larger capacities & much lower cost than SSDs ; longer lifespans for writing & re-writing than SSDs
Cons = Much slower than SSDs ; mechanical / moving parts are prone to breakdown
The writing / re-writing part is why SSDs are good for the OS and programs. OS's and programs don't usually take up much space, and once you install them, you aren't likely to delete them / install new ones every few days or weeks; only small changes are made here and there to your settings, etc. They also recommend NOT de-fragging your SSD, because (1) it's essentially unnecessary for this type of drive, and (2) it will shorten the lifespan of the drive.
Conversely, that's why HDDs are better for data, especially large amounts of data; they can withstand being written / re-written over and over again. Video editing, downloading movies, music, etc. can all take up a lot of storage space, and are of a more transient nature. You may not keep them for more than a few weeks or months.
And the point of de-fragging an HDD is speed: if the dive has to access different spots on the disk instead of one area (the file is fragmented), that takes more time (= slower access time); if the data is all in one spot, the access time is faster. In an SSD, it doesn't matter if the data is fragmented; you won't see a slowdown in performance. From the
Cruical Memory website:
Mechanical drives have a relatively long seek time of approximately 15ms, so every time a file is fragmented you lose 15ms finding the next one. This really adds up when reading lots of different files split into lots of different fragments.
...
However, this isn't an issue with SSDs because the seek time are about 0.1ms. You won’t really notice the benefit of defragged files — which means there is no performance advantage to defragging an SSD.
So the seek time of an SSD is ~150× faster than a traditional HDD.
