I returned a faulty 3TB Barracude and got a new one recently (ST3000DM001)
I'm trying to figure out why this drive is so slow. (Read is really slow)
Here are my results:

From reading online I should be getting something close to this:
 
ATTO-Seagate-Barracuda-3TB-HDD-ST3000DM0
 
I've tried different sata cables, different sata ports, different power cables, etc'. The drive is on AHCI mode.
 
Should I try anything else or is that another fault drive?
 
Thanks,

It's not just about the hard drive it's about other system hardware as well. In that second picture the machine also has a Intel i7 and a nice motherboard and probably a good chunk of memory. A high performance system is going to move more data much more quickly

I forgot to mention that I also own a nice motherboard and i7-4770. I don't think that's the problem. With my SSD and another drive I get pretty much the same results reviewers have posted.

Definitely keep it in AHCI mode. What format is the drive? I would try diffrent settings in that benchmark so it tests 512k and 4000k cluster size. or try a different benchmark tool. Update firmware, drivers etc. Download the seatool  and do a surface scan on it. The drive is connected internal and not in a enclosure right? I would also update the motherboard controller drivers and bios updates. If you have other drives that generally benchmark better than this drive, then it's likely faulty. I read mixed reviews on this paticular drive and many have ditched seagate. Many of the 3TB drives outright died a couple months after purchase. How was the drive packaged? I have seen a lot of horrifying things when it comes to packaging.

My first guess is that DMA is not enabled for this device.  Is this windows 7 can you provide us with a speccy of your system?

 

How to speccy

 

How to enable DMA windows 7

 

  1. Open the explorer (STRG+E)
  2. Right-click on “Computer” and click on “Manage”
  3. Click on “Device Manager”
  4. Uncollapse IDE ATA/ATAPI controllers
  5. Right-click on any label where “Channel” is part of the name – Click on Properties
  6. Go to the Advanced Settings tab, under Device Properties check “Enable DMA”

It may well be another bad drive.  Seagate 3Tb are currently the drives with the highest failure rates on the market.  Especially ST3000DM01 models.  Most only are lasting a year or two at best.  You're much better off RMA'ing it and get yourself a good HGST or Toshiba drive instead.

The drive is in ACHI mode and DMA is enabled.

 

Here are 2 tests one after the other. If I'm reading this correctly the drive gets really slow on 3 places. Is that enough proof to get that drive replaced?

From that chart, I'd also say that it's possibly just a background process that's interfering.  Is there anything installed/stored on the drive that might be getting accessed by another program?

Ok, some findings. I recently installed a new firewall called Windows 10 Firewall Control . For some reason when that was installed a proccess called LMS.exe (Intel related) was eating up CPU more than it should.

After removing the firewall I run another HD Tune test. The CPU usage is now low but the drops are still there and the drive is sill slow when moving files \ extracting files.

You should check SMART errors.

I had already asked for a speccy profile which would have included any smart errors but he did not provide one.

Sorry about that! I was sure I pasted it.

It does appear like there is something wrong as your average transfer rates are much lower than the benchmarks posted.  I suppose the last resort would be contacting seagate.

What is strange is the spikes on both charts are occuring at 900gB intervals.

That would mean something else is accessing the drive during the test. I would turn eveything off in msconfig and firewall antivirus stuff temporarily and do another benchmark. The sequential speed for read is terrible, but the write is spot on. I would RMA this thing I was you. When in doubt throw it out.
