I agree with GoughLui, you definitely have issues with your power supply. In order to perform the miracle of random writes to an SMR drive, the drive contains a persistent cache in the outer diameter tracks, which is basically a “log” of changed sectors. While that’s true, the exception is when a drive fails and a RAID rebuild has to occur. INTERNAL DRIVE: Crystal Disk Info reports the drive inside this case to be a Seagate ST2000LM007, a thin 7mm, 2.5" 5400 RPM drive originally introduced in 2016 in the Mobile HDD line of drives. I think you should also test it with your “regular” non-SMR drives and even with SSD with write caching off. - Seagate 8tb Ironwolf ST8000VN004 Internal Hard Drive for Parts. As it’s drive managed, you can’t control when these updates happen – so real-time software will need decent buffering to cope with that. In such cases where cost/TB is a big driver in the decision process, the Archive drive comes in very handy. My Freenas server was built around 1TB drives with half hourly RSYNC backups from my working drive to the backup drive. Delivering absolute lowest cost/TB along with the performance and reliability required for massive scale applications, the new 8TB HDD is ideal for meeting the needs of our enterprise and service provider customers who demand optimised hardware and the cost structure needed for massive scale out. We work hard to protect your security and privacy. However, there are some Seagate 8Tb USB 3.0 units which are pre-built and are likely to be certified to be working by Seagate themselves. The removed drive was then reinserted and a RAID rebuild initiated. Seagate IronWolf 8TB Internal Hard Disk HDD. Click on the Policies tab. Hoping this one will last longer than the WD Blue, Reviewed in the United Kingdom on 9 March 2020. Our last Enterprise Synthetic Workload is comprised of a 128K large block sequential test that shows the highest sequential transfer speed for a platter drive. We ran several tests to characterize the Archive drive’s limits. Where I used to work we’d order the drives from Synnex by the box of 20, and they would just send on the box directly from the manufacturer. We’re still in early days of SMR technology, so some level of experimentation is required. The read and write speed averaged {137.5MB/s, 134.3MB/s} and {137.2MB/s, 134MB/s} respectively. Delivery Associate will place the order on your doorstep and step back to maintain a 2-meter distance. Issues with write speed have been experienced, especially with HP Microservers, where the BIOS defaults to Write Caching disabled. SMR-enabled technology ensures efficient and economical cold storage operations even in the harshest data centre environments. The Archive drive furthers the TCO argument by being power efficient and low-cost, roughly 50% less expensive than a traditional enterprise 6TB drive. However, my next order for two more drives came “direct” from Amazon. The drive comes with impressive burst results but lower sustained write results, which are to be expected in this class of SMR drives. Industry's best cost/GB/watt 8TB hard drive, NOT SUITABLE for Network Attached Storage Server ( NAS). In stock on November 19, 2020. It’s not just me, there’s reports all over the place and other reviews showing their write speed graphs being shot to hell… which is why I’m wondering how *this* review had such a nice write graph ( multiple point samples? These profiles have been developed to make it easier to compare to our past benchmarks as well as widely-published values such as max 4k read and write speed and 8k 70/30. You cant keep checking terra bytes of data to see if they are all valid. The Seagate Archive HDD sports the usual standard hard drive design of a silver top cover and black metal body. ). Moving huge or small files onto it with avg 100MB/s. It’s absolutely fine for reading, but writing performance can take a serious hit under heavy random write access and is less consistent compared to PMR drives. When the power company switches their lines during peak/off peak hours, sometimes the computer would reboot.. StorageReview strongly recommends against such usage, as at this time SMR drives are not designed to cope with sustained write behavior. So my cunning plan is to use these new drives as internal storage, which used to be handled by a trusty HP microserver running Freenas. Removing the Philips screws allows the board to come free – two main chips have a thermal pad connection to the chassis for cooling. All good. In reality, Amazon has a separate channel for this type of thing, but I’ve never had a problem with it. Generally soft-raid is more forgiving of occasional slow-responses, and can be configured to be somewhat more tolerant, especially if NOT used for striping (which would be silly on these drives). In this first testing section we look at the performance of the drive in a single drive scenario inside the StorageReview HP Z620 Workstation. In our iSCSI block-level test of the same benchmark, the Seagate Archive measured 158.48ms at 2T/2Q while reaching 657.2ms by 16T/16Q. Your question may be answered by sellers, manufacturers, or customers who purchased this item, who are all part of the Amazon community. Arrived fast, the packaging nice size box with two flexible plastic inserts that hold each end of the HDD meaning it is esentially suspended in the box with a lot of shock resistance, but it would be good if Seagate can come up with a non-plastic version of that. The sides of the Seagate Archive HDD feature a total of four screw holes, which allows us to mount the drive. At the moment, we don’t have a benchmark in place to measure hyper-scale environments with massive object-store filesystems that can distribute parity data without the use of RAID. Utilizing SMR technology, Seagate Archive HDD drives can pack up to 8TB capacity into a single 3.5” form factor drive. It is not Flash memory, vulnerable to charge leakage, which is mostly blown out of proportion by the 840EVO’s TLC flash issues. As such they are powered off all the time and only spin-up to take the daily backups. The drives are also more efficient to run, and have a lower cost than traditional enterprise-class 6TB drives. Note: BEWARE the Samsung SSD Cashback Promo! I purchased two of the drives over a month ago at AU$379, which is a little much. As a single drive it’s fine, if the use case can tolerate slower sustained writes. With the cache on (showing in BIOS, and confirmed with hdparm) the writing went very nicely until 39GB, then the drive froze up (system was still responsive) until it offlined itself and I went in there and manually remove and reinsert the drive. I’ll go try with caching on, though I must admit, I’m somewhat disinclined to run like that for the usual reasons. Eight terabytes. RAID controllers will kick drives out of an array even if the SMART says it is good, if the drive takes longer to respond to commands than it should. Data centers using climate controlled and power controlled environment can use them for cold storage but not for personal use. The 8TB drive now partially comes to life, but gives me (among others) this error in syslog; Even when I change to another computer and an eSATA port dock, and now won’t mount or let me do anything further with it; >>>> link online but 1 devices misclassified, device detection might fail. These are archive drives.... these are meant to be cheap, these are less then 14,000 RS. However, for many “home” applications, you won’t notice the difference. Switching to the iSCSI block-level test, the Seagate Archive measured 25,340 IOPS read and 12,639 IOPS write. As usual, the drive comes in an anti-static bag. It would be great to know how other’s are dealing with this drive in enclosure or docking station. In the first of our enterprise workloads, we measured a long sample of random 4k performance with 100% write and 100% read activity to get our sustained random I/O results. Suffice it to say, no SMART errors were thrown throughout a month of testing on both units. Switching to the iSCSI block-level test, the Seagate Archive measured 123.85ms read and 711.20ms write. PMR was introduced when drives using longitudinal recording hit their limits at about 320-400Gb, and has proven itself to be relatively reliable with the majority of today’s drives using PMR. I have an 8TB Seagate SMR archive drive, and the first 15~20GB contiguous sequential write goes very nicely at anything between 150~120MB/sec, but then it falls apart, rapidly, down to 1~30MB/sec. They dont run colder and they run slower.. Their reliability is unknown. When we calculate the Seagate Archive’s standard deviation, it shows us just how consistent the latency results were within each of the categories during the above benchmarks. StorageReview is no stranger to Veeam in the lab, using it in past reviews as well as leveraging it to backup our own testing platforms. Bought 3 hard disks. If there is a power failure, that file you are copying would show up as a 0 byte file, so you delete the file and recopy the file again. Thanks for taking the time to comment, and much thanks. Its 4K throughput was the highest for write at 2,693 IOPS and it had an impressive average latency at 0.37ms. Since most hard drives reach their rated performance level very quickly, we only graph out the main sections of each test. For comparison, please see this article where WD and Seagate 4TB PMR drives are tested. Really reliable and expected speeds for this type of drive. The results from this scenario weren’t a huge surprise since we had built it out knowing the limitations and performance qualities of this SMR HDD. The Archive posted 4K throughput read results of 514 IOPS (CIFS), 2,067 IOPS (iSCSI), and average read latencies of 497.07ms (CIFS) and 123.84ms (iSCSI). Please try your search again later. Unfortunately, because it doesn’t seem to be able to compute the size of the MFT after the test files are placed on the drive, the Write+Verify test fails with an error that the drive filled up quicker than expected (as the MFT grew due to the number of files written by the test). Sorry but your basic question is one that depends on several variables which are not possible to guarantee, as incompatibilities can sometimes arise due to older drivers or BIOSes. Just make sure when you partition the drive (even as one partition) inside “Create and format hard disk partitions” under Windows, you choose GPT, otherwise you will not see the full capacity of the disk.
