Seagate BarraCuda ST4000DM004 4TB 5400 RPM 256MB Cache SATA 6.0Gb/s 3.5" Hard Drives Bare Drive - OEM

Pros: For a 3.5 inch drive it is very thin Very quiet under load and idle No bad sectors or errors 2 year warranty isn’t too bad in case something goes wrong. Benchmark performance results are listed below: Crystal Disk Mark: • Seq Q32T1: Read = 220.73 MB/s, Write = 145.27 MB/s • 4K Q32T1: Read = 2.09 MB/s, Write = 1.454 MB/s • Sequential: Read = 216.63 MB/s, Write = 165.37 MB/s • 4k: Read = 1.18 MB/s, Write = 1.42 MB/s ATTO Disk Benchmark: • Read: 214.41 MB/sec • Write: 175.16 MB/sec HD Tune • Minimum: 105.8 MB/s • Maximum: 210.2 MB/s • Average: 171.0 MB/s • Access Time: 14.2 ms • Burst Rate: 239.63 MB/s Power Consumption • Idle = 4.8 Watts • Load Read = 6.9 Watts • Load Write = 6.4 Watts Maximum Temperature while testing: 93.2 °F

Cons: Write speeds are a bit low compared to the read speeds Despite many attempts the drive refused to enter its low power sleep state where the platters stop spinning and the head docks itself. Tried changing windows settings and bios settings but still couldn’t get it to sleep.

Overall Review: Overall this drive performed very well for a mechanical hard drive while running relatively cool. It’s good to see that mechanical drives are still improving and finally getting close to the SATA II (3 Gbps) barrier. Considering its low price, this is a great choice if you need a drive with more space than then your SSD. *All tests were conducted three times to ensure accuracy and repeatability of results.

Pros: - Arrived with no read/write issues - Noticeable performance improvement compared to old drive - No problems under GNU/Linux

Cons: - None

Overall Review: - Under Fedora Workstation 25, the drive benchmarks the following averages with a sample size of 10 MB: 155 MB/s read, 91.2 MB/s write, 14.36 msec access time - Testing done on a BIOSTAR A880G+ motherboard and Phenom II X4 - Drive ran continuously for 21 days with no signs of problem

Pros: Quiet Operation Low Price

Cons: None observed

Overall Review: I've had this drive for a few weeks and thus far it's been rock solid. This additional drive compliments the four drives I already have in my FreeNAS deployment. When this disk came in I added another and then dropped that pair in as an additional Mirror pair in my existing mirror stripe for a six disk "Raid10" in other NAS devices. With a total of 8TB of useable space this NAS provides a data dump of storage for my home lab environment. These disks are quiet and do not chew up a large amount of power. They also do not generate a shed load of heat either. Overall a solid purchase. Seagate has cleaned up their act and I won't hesitate to purchase more when the time comes.

Pros: Cost effective for an SATA III 6.0 7200 RPM drive. Slim design measuring just over three quarters of an inch thick ensures it will fit in most all desktop cases. Runs cool and quiet under medium duty use for me. For the price these are great drives for just about any machine. Would also work great for a small NAS setup, or even installed in a portable USB case for external storage if need be. This SATA 6.0 drive is also backwards compatible with older motherboards with earlier SATA (II) 3.0 or SATA (I) 1.5 ports. However, the maximum speed of the drive will be slower due to the lower speed limitations of the port. For those that may need some help when replacing/upgrading an older drive/system, check out the Seagate DiscWizard software available on their site for free. DiscWizard lets you quickly install your new disc drive with wizards that guide you through the processes of creating and formatting partitions on your disc drive, transferring data, and backing up your data. On Seagate’s web site this software can be found under the Support/Software & Apps section along with full instructions. Seagate also offers two larger drives in this Series, the 2TB 7200RPM with 64MB Cache, and the 3TB 7200RPM with 64MB Cache. At these prices its worth spending a little more for the larger capacity drives they offer, so check them out if you need more storage space! Bare drive comes UN-formatted and ready to set up, simple plug and play. Firmware Version CC46, and has a 2 year warranty.

Cons: NONE!

Pros: The drive worked like a charm. Installation was a breeze, as with most internal SATA drives. Boot and access time seem fast. Cheap and decent drive. Hopefully it lasts a while.

Cons: None

Overall Review: Seems to be a good drive for the price.

Pros: Does exactly what it needs to. No frills drive with barebones packaging but that's exactly what I need for some builds and I don't want to pay extra for accessories I don't end up using. Runs cool and quiet so it should have good longevity. I've been using BarraCuda drives for years without a problem so I expect this one to be the same. I see there are already a bunch of benchmarks uploaded so I'll skip that part, but the performance is pretty much what you would expect from a hard drive.

Cons: Price could be a little more competitive for the capacity. It's not too hard to find a bigger drive or an SSD for a few bucks more on sale. If you are building an absolute budget machine though and can't spare any more cash, this definitely fits the bill. I would avoid using used hard drives too, even if they're cheaper unless you're ok with losing whatever is on it- you never know what kind of abuse they've been put through. You're not going to get close to SSD performance out of it obviously but I put it into a PC that will be used pretty much just for web browsing so for that it's perfect.

Pros: Standard green 500gb SATA hard drive. It came well packaged and didnt have any problem with benchmarking it or formatting it. My overall results were an average read speed of 150 megabytes/ second and the write rate varied more depending on the file size Larger files I was able to get write speeds of near 100 megabytes/s With the smaller files it would vary more and was closer to 50 emgabytes/s which is typical of mechanical drives overall the performance is what you would expect from a mechanical green drive. Not spectacular but good enough for your average computer OS or for just storage.

Cons: Not sure what the target market is for this drive. The only thing i could think of would be an average office workstation. But at the price point you would be able to get a small ssd and the average office workstation would become a more productive machine for the employee.

Overall Review: Overall it's a good drive for what it is but at this point the size is somewhat pointless. 500gb while might be nice to have i don't see why the average consumer would be buying it. I would rather have a 64/128gb ssd over a 500gb mechanical drive and the prices are still very similar.

Pros: Two year warranty 10/6/2017 an update on how this drive has performed. In a word-Flawless. In the age of uber mass production and even cheaper prices per GB ( Listen up sonny, back when gas was affordable, a 47 Gigabyte(!) seagate scsi drive cost me $500 and I was overjoyed to get it ( very short supplies) oh yeah its like 18 years old and while a little bearing noise is present it still works like new. you have to start treating current consumer grade hard drives like the 8-track tapes they are and be ready to clone and replace them every couple of years. come on folks under $30 TB?. I'm sure they'd be plenty reliable at $100 TB, like the so-called enterprise class drives. I'll be the first to chime in that it stinks to get a stinker, especially if you don't install it for a couple of months. I've been using seagate for a long time and never was wronged, which is pretty good in the long term players market. Consider the time you've spent building your digital archive. clone your data to the replacement and retire the original while you have no doubts it can spit your data up if need be. I'm on a two year cycle for the SSD that is my main boot drive, not that I've had any trouble, but I have to be prepared as losing my work PC for a day would be painful. I still rate it.... ------------------------------- Good Value Quiet Passed without fault my torture tests, which includes killing power while writing a big file and an overnight surface test. No Bad sectors out of the box.

Cons: For those who buy on impulse or don't fully read descriptions, there are no cables or fixing screws included with a _bare drive_ However, they can always be found for just a few bucks. Unless you have a specific reason, stay away from locking sata cables. Easy to damage a drive if you "forget" that the cables lock in place.

Overall Review: I'm hoping Seagate has tilted their budgets to better QA on products people trust their important memories to, even when they are foolish enough not to keep a full readable backup on an external drive. I guess we'll see how many people complain about issues on this new series of hard drives. The 3TB range is pretty optimal for a whole bunch of reasons and with prices hovering around $25-30 a TB this drive falls into the sweet spot of brand loyalty. You can populate an array without breaking the budget. Seagate drives appear to have had some quality issues in the past if you read the reviews, but consider all the working drives people don't care to write a review about. While today's manufacturing systems have reduced prices drastically, we're packing data tighter then ever and even a minor fault will result in lost data. (like all the pics from your bachelor party!). Keep good backups. I consider today's drives sort of disposable; if you do also, have a look at the other drives in Seagates line, specifically the Firecuda, with it's five year warranty. Easily worth the extra costs if you can get by with a 2TB unit and do not have the budget to purchase enterprise level hardware. A five year warranty shows confidence. I need confidence. After two years my drives get replaced and I use the old drive as a long term backup and I have a box at the bank holding my drives from the last ten years. One of em wouldn't spin up during the annual review. I eventually broke the stiction (GTS) and was able to mount the drive and copy all the data back to my PC. What's a ten year old 80GB drive worth ? ( $10) The data on it?..well you don't want to know what that is worth now do you? I'm using this drive in a HTPC as the primary recording drive now, data rates are what I expected, your results will most certainly vary but in the 3TB drive segment, the Seagate puts on a good show at a competitive price. I'd rate it as a good buy with it's two year warranty and five eggs I'll update this review in the event of something noteworthy happens, but I expect it to be smooth sailing
