Product Information

SMR has worse sustained write performance than CMR, which can cause severe issues during resilver or other write-intensive operations, up to and including failure of that resilver. It is often desirable to choose a CMR drive instead. This thread attempts to pull together known SMR drives, and the sources for that information. url=https://hdd.userbenchmark.com/SpeedTest/9154/ST500LM000-SSHD-8GB]Userbenchmark: Seagate ST500LM000-SSHD-8GB 500GB[/url] Our servers are getting hit pretty hard right now.

Key Advantages - Seagate

The irony here is that competitors are likely to use the same Seagate 5TB internal hard drive. The LaCie Porsche Design 5TB USB-C Mobile Hard Drive is far more expensive and doesn’t come with the Mylio Create software bundle. However, it has a more attractive finish and a Type-C connector. LaCie is a Seagate brand. Seagate’s third generation SSHDs (solid state hybrid drives), now for both laptops and desktops, are marketed as a replacement for HDDs and serve as a good option for those otherwise considering an SSD. SSHDs aim to offer users the price-point and robust capacity of HDDs while also utilizing NAND flash to provide the performance attained with SSDs by caching critical applications. Slimmed from 9.5mm to 7mm, our review model third generation Seagate 500GB SSHD Thin with 8GB of MLC NAND would fit well in any user configuration and is especially well-suited for ultra-thin, ultra-light laptops. What I wrote four years ago is still valid; large-capacity portable hard drives have reached a plateau. There’s not much hardware improvement that can be made as there is little to no incentive to invest in R&D. New technologies like HAMR or Helium are reserved for more lucrative markets like data centers where the need for smaller 2.5-inch hard disk drives is non-existent. PerformanceSeagate® Laptop and Laptop Thin SSHDs fuse the blazing speed of SSD with the high capacity of a hard drive. Seagate platter sizes 2.5": https://rml527.blogspot.com/2010/09/hdd-platter-database-seagate-25.html Installs and works just like a traditional hard drive in any laptop or PC, and with any OS and application Drive Managed, DM-SMR, which is opaque to the OS. This means ZFS cannot "target" writes, and is the worst type for ZFS use. As a rule of thumb, avoid DM-SMR drives, unless you have a specific use case where the increased resilver time (a week or longer) is acceptable, and you know the drive will function for ZFS during resilver.

The Seagate SSHD Gen3 power consumption is lower than the Gen2 in every test but idle, where it is nearly the same. Across the board, the Gen3 made strong gains and saved 0.3-1.2 watts depending on the job it was doing. In the StorageMark 2010 HTPC 4K Disk Capture, the Seagate Gen3 offered substantially higher performance, boosting throughput by 18.5% over the previous-generation model. Behind the scenes though, we did notice that before the data was cached, the initial transfer speed was slightly slower than the original 7,200RPM-based models and took much longer to be absorbed as “hot data”. With any laptop drive, power consumption is an important factor for users. The key sources of power draw get narrowed down to either the bright screen or the storage device used. In the next test, we record the average power consumed over a small range of synthetic benchmarks. For reference, Seagate lists an average idle power rate of 0.9 watts and an active seek rate of 2.5 watts.Seagate Laptop SSHDs integrate NAND flash with traditional hard drive storage to create a laptop drive with the speed of solid state and the capacity of a hard drive.

Toshiba's list of DM-SMR drives: https://toshiba.semicon-storage.com/ap-en/company/news/news-topics/2020/04/storage-20200428-1.html While not a bombshell, Seagate’s Gen3 model does provide cost-efficient performance and a significantly lower starting price than the Gen2 Momentus XT 750GB. Our benchmarking shows the Gen3 and Gen2 both outperform HDDs where it matters, in our real world traces where the onboard cache can really show its performance benefits. In that case, where data is nicely cached, the new 500GB Thin bests the 750GB Gen2 product by a significant margin.

Ironically, the barebones 5TB drive is up to 50% more expensive than the external model, despite having fewer materials (no cable, chassis or electronics); the laws of supply and demand at work.
