Why mechanical-HDDs that are advertised as SATA2 3Gbps devices don't actually perform at that rate? I tried duplicating a file in the same drive and it was copying at 40MBps;
3Gbps is 375 MBps !

Its connected to my sata3 6Gbps ports - don't think this matters anyway

HDD Drive industry is having a hiccup this quarter sad.gif That's why "potong" warranty service / cut cost

Well those are MAX speed you can get based on manufacturer specification / under their most optimal/best

Other factor varies thus effect the overall performance which we can expect is slower then rated spec when it come to end-user

But thats only like 10% speed...
Its like subscribing to Unifi 5Mbps and getting 10% speed only (64 KBps)
or buying a Ferrari which claims it can do 300 KM/h but can only hit a top speed of 30 KM/h !!! doh.gif

Sata 2 spec is the interface of the HDD, not the ability of HDD physical write or output.

The heck I know, but most likely it is the case like what u said.

Looks like I am not going to buy a new HDD for 2 years time since i have enough to use for now, as long as I try to conserve my capacity usage, or burn some of my media/movies files to DVD-R.

Lol.. Unifi is 5Mbps.. But your Wifi can support up to lets say 54mbps. And your LAN can support up to 100mbps.

Does that mean that your internet can reach 100mbps? tongue.gif

5Mbps = 625 kBps

They will try to repair/refurbish their machines....i dont think they will reuse the water-logged components. Water-logged components are generally impossible to be reused...

It isn't 10% of the speed.

SATA 3.0 Gbps uses 8b/10b encoding, leaving only 80% for the actual data transfer.

So,
80% x 3 Gbps = 2.4 Gbps
2.4 Gbps = 300 MBps

Or at least that is the theoretical number. Real world tests on SATA 3.0 Gbps with SATA 6.0 Gbps SSDs has revealed that the practical maximum speed is about 265 MBps.

And your HDD test is flawed because it is like driving your Ferrari from A to B to A in t time and then claim it takes t time to drive from A to B, which is what you actually did in your HDD test. The more appropriate test would be for your CPU to write to the HDD, which has seen numbers up to 150MB/s in typical HDD benchmark tests.

The moral of the story here, is unless you know what you are doing (like being intentionally misleading), use proper benchmarking software to benchmark.

tl;dr: It is 56.6% (practical) or 50% (theoretical) and not 10%.

poor move by Seagate to reduce the Barracuda range to 1 year, 2 year is not that bad la. I know Seagate got a lot of contract with OEM, so don't care.
