Question Slow Firecuda 2TB 2.5" (60 to 10MBps)

I had newly purchased 2TB FireCuda for my laptop and migrate the OS. Sometimes it is very slow to transfer files with 60MBps after a hour it will goes 10MBps and it also affects the programs which it will not responding. Is this normal for SSHD? It was first time for me to use SSHD and I know HDD 5200pm is slow but not as slow my current SSHD. My old HDD is more responsive for multi transfer but only peak speed is 50MBPS. But on SSHD bootup is very fast and I did the CrystalDiskMark benchmark which is pretty much fine. It's kind of weird I tried to test SeaTools which gives response Ok condition.








 
If copying from USB, many laptops have USB 3.0 ports/circuitry that will actually overheat and throttle in sustained file transfers exceeding even a few minutes...

Try one of the 'slower' USB 2.0 ports, which your drive will not be capable of saturating anyway...

To test strictly drive speeds, you'd have to copy/replicate large folders renamed that exceed the cache size, or, preferably, on a cold boot test to that nothing is pre-cached. (That way you are not limited by 110 MB/sec network speeds, assuming 1 Gbps wired network, or potential USB 3 throttling....)

I'm frankly surprised you are even getting 140 MB/sec sequential reads on a 5200 (not classic 5400 rpm?) rpm drive...

How are you doing the transfers, from where to where, when you see speeds fall to 10 MB/sec...? From USB drives or network?

With SSHD it all depends on what you are doing. If you a putting fresh data onto the drive, it's not going to be any faster than a standard hard drive. SSHD shines when it comes to routine tasks that you perform all the time, and it can keep that data in that SSD portion of the drive.
