Seagate BarraCuda Pro Performance Internal Hard Drive SATA HDD 8TB 6GB/s 256MB Cache 3.5-Inch (ST8000DM0004)

Attend the ST8000DM004 (seagate indicates ST8000DM0004). I ordered this drive and the box presented, ST8000DMB004. I preferred not opening the box until I knew what I had, so off I go to find out what is this B. I checked with seagate; they had no idea. Amazon has not responded as of this entry, but I will save the attentive the irritation by stating you can ignore it. The drive is ST8000DM004. Could the B mean bare? I have no idea, but it should then state that somewhere on this page.For those wondering between ST8000DM0004 and ST8000DM0005 8TB. The M0005 is slightly heavier and uses more power. idle 7.2w to 4.5w. startup power 2.0w to 1.8w. operating mode 9w to 6.8w. oddly, the M0004 draws slightly more watts in standby/sleep at .6w to .8w.The drive runs cool and quiet, and through a pcie sata port adapter copying at 200MB/sec. not great when copying 6TB, but better than 60MB/sec.

I ordered these on 09 May 2018 and I received the same type of drive as in Amazon's photo. When I ordered, the drives were shipped and sold by Amazon. I wanted to make this clear, as I saw several reviews stating that the drive you will receive, should you order one, will be a drive that was pulled out of an external hard drive enclosure system.However I did receive one drive in a box that had already had its label cut open, but the anti-static bag around the hard drive was intact. Also, the date of manufacture (DOM) on the hard drive labels is older than on the labels on the box.I ordered 2 of these drives and set them up in a RAID 1 array (mirror) using IRST, and it is satisfyingly fast for a set of mirrored 8TB 3.5" drives. I copied 3.83TB of data from my single 8TB archive HDD that I pulled out of an external HDD enclosure that I used with my laptop to this new RAID array. The process maintained transfer speeds of around 170MB/s, maintaining a lower rate for smaller files and a higher rate for larger files. According to task manager, the process was mostly limited by the read speed of the archive HDD. This is as fast as I need, and this should be the largest amount of data I need to transfer to the drives for a long, long time.

My Seagate Desktop HDD 2TB internal hard drive which made in China was very quite. After replacing it with Seagate BarraCuda Pro 8TB Internal hard drive on 6/20/2018, new HD works fine. However it makes continue loud clicking noise. Therefore replacing the 8TB BarrraCuda Pro with a new one on 7/1/2018. The second 8TB BarraCuda Pro hard drive didn't make clicking noise, but making loud grinding noise. After talking with Seagate tech support, they ask me to try 3rd one. All of these three 8TB BarraCuda Pro hard drive are made in Thailand in June 2018. The third BarraCuda Pro 8TB internal hard drive has same loud grinding noise. I am very disappointed for the quality of the Seagate's hard drive. I had attached a recording for your own judgement. (https://www.amazon.com/clouddrive/share/YHbWB6nmHdoRt8yZE8SbdpcZeaiJh2k5TpSFvPQZi2J) Please note that: From 3:06" desktop starts to run Random Write 4KiB of CrystalDiskMark.It is ST8000DM0004 drive, not ST8000DM005 because 8TB BarraCuda Pro has two models.Seagate should showcase their solid hard drive to change customers' view by sending them a great one.7/24 Update:When size of hard drive increases from 1 TB to 8TB, reading heads increased too. Thus noice increased (usually 2TB hard drive has 6 heads). Because ST8000DM0004 hard drive has 14 heads, it has constant grinding noice specially in quiet office environment. My colleague said to me that you are grinding coffee beans.ST8000NM0055 hard drive has only 12 heads, therefore it has relative lower noice. Both hard drive have same 5 years warranty. Based on Seagate's specification, the difference is that ST8000NM0055 has 0.44% annualized failure rate while ST8000DM0004 has 1% annualized failure rate.One thing I noticed that the temperature of ST8000NM0055 and ST8000DM0004 are 48C and 41C respectively.

The first one of these I received made a clicking/thunking noise about every second or so even though I wasn't accessing it. I was using it as a secondary drive on a PC. The noise sounded like the actuator arm was having difficulties finding it's place. From years of working with drives, and having heard this noise before, this did not bode well for the longevity/dependability of the drive although I could not get it to fail the basic tests in Seagate's Seatools. I've learned to not wait too long to see what happens next and I always back up. Based on other reviews, I wasn't going to take any chances. I needed this drive to work dependably. As a result, I sent it back to Amazon as defective within the 30 days of purchase -- no problems with the return -- went smoothly -- thanks Amazon! The new replacement drive does not exhibit this noise I described at all and is perfectly quiet when not in use -- spare an occasional click. My suggestion to anyone who is buying this drive is to not use the "quick format" so you are sure the drive is working properly. Yes, it will take quite a few hours to do a full format, but it's worth the piece of mind. I've always liked Seagate drives -- for the most part. I've had a few bad ones along the way; doesn't matter who makes it. You just need to make sure you don't have one of those that isn't quite right to begin with. In closing, I have considered that the drive could have been perfectly fine out of the factory, but was dropped / damaged in shipping -- especially around the Holidays which is when I purchased the first drive. If I have any problems with this replacement drive, I will be sure to update my review.

I got this drive for its storage size. I was quite impressed that it was basically plug and play. No installation issues and transfered all my data. Still have about 4 terabytes left. Sometimes you can hear it audibly click on but other than that it works great as a storage drive.
