Difference in Primary/Secondary SSD Performance

PhysicsMan94 · 21 Jan 2015 at 23:32

Hi there, I was thinking about getting another SSD (currently have a 256GB Samsung 840 Pro and a 2TB Seagate Mechanical HDD) for storing more of my games on as the load times from the mechanical are not ideal / pretty lacklustre compared to the games on my SSD.

I was wondering how performance might differ between my current SSD with my OS installed on and a new one (I'd probably get the 512GB Samsung 840) - would the read/write time difference between the 2 be negligible?

Cheers

I got rid of my Mechanical HDD and went full SSD, 250GB 830 OS+Apps, 500GB 840 Games and 1TB USB 3/2 SSD for back up.

Performance is not effected.

It would be pretty noticeable. Run a read/write speed test on your OS' SSD, then compare that with the numbers available online for the same drive being ran as a secondary drive. The lack of constant read/write being performed by the OS and its applications should be pretty apparent!

i have 2 x 250GB Samsung evos 840s as my HDD failed and they where going cheap so grabbed another to replace it.

i was getting the same read and write speeds from both drives using the Samsung software.

Might be best to use a more impartial benchmarking tool than Samsung's own offering. Not that I'm saying they'll inflate their numbers, but if you use one not made by an SSD manufacturer, you know the tool is benching the drive in the same way any normal program uses it (whereas the Samsung software already knows the ins and outs of said drive, and might use this to speed it up).

Real world speed differences between the good (450-550MB/s+) SATA 3 drives are negligible at best.

You'll notice the difference between a 500MB/s class drive and a 300MB/s class drive, and either will **** all over a HDD, but beyond that the only real difference is in benchmarks or REALLY I/O heavy tasks.

Didn't read the question

I see, but I assume the speeds would be much better than running off a secondary mechanical HDD though? As long as the performance wouldn't be too much slower than my primary SSD then it would be ok (for running games off this secondary SSD).

Would be no real world differences between switching your OS ssd, I would just upgrade your game storage drive to a 480gb+ ssd and all will be good
