In the File Server profile, the Seagate Gen3 offered substantially better performance than all of the competition from 8-64 IOPS at 3x-5x. However, at 128 IOPS, the Gen2 was tops. Our Database profile again showed the Seagate Gen3 as a strong runner-up to the Gen2 plateauing at 64 IOPS, steady to 128. The Serial ATA interface connects each disk drive in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This essentially means both drives behave as if they are Device 0 (master) devices. Rounding out the figures, in our Workstation profile, the Gen3 placed a solid second, again to the Gen2. The Gen3 plateaued at 64 IOPS and had a minor decrease at 128 IOPS.

For 2MB random transfer, the Seagate Gen3 came out at 73.5MB/s and 86.6MB/s, placing second only behind the Seagate Gen2.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.

The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advantages include: In the 4K Random Transfers MB/s, the Seagate Gen3 again ranked second behind the Gen2, with the Gen3 at 0.496MB/s and 0.896 MB/s. The Seagate Gen3 also ranked high above most of the competition at 127.1 IOPS read and 229.4 IOPS write, but first place was snatched up by the Seagate Gen2. The SSHD serves to satiate the demand of users looking to couple performance gains and storage capacity without breaking the bank – think gamers and media enthusiasts. However, SSHD technology is not a cure-all, which Seagate readily admits; users craving extreme performance will likely desire more than an SSHD provides. Yet, for the market of HDD users Seagate is focused on, the Seagate SSHDs offer users improved performance at a lower price than SSDs.Along with the change in nomenclature, Seagate implemented several platform changes to the SSHD Gen3 as well. While Gen2 provided users with 8GB SLC NAND, the Gen3 switched to 8GB MLC NAND. This modification does sacrifice some endurance, but the majority of users won’t deplete the endurance for the lifetime of the drive’s warranty making it mostly a non-issue. By switching to MLC NAND, Seagate is also able to reduce the Gen3 production cost greatly and thus lower the price significantly. Seagate has also decided to streamline their laptop drive production by exclusively offering 5,400 RPM drives. So while the Gen2 had a 7,200 RPM drive, the Gen3 spins at 5,400 RPM. Thanks to improvements in the cache technology, the cache miss pain of hitting the slower spinning drive should be mitigated, but regardless, hitting the drive without flash assistance is going to hurt a little more than in the Gen2 drive. 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”.

The first is our database profile, with a 67% read and 33% write workload mix primarily centered on 8K transfer sizes.

Hard Drive Benchmarks

When it comes to measuring performance of the Seagate SSHD Thin the two categories of benchmarks that we commonly test all consumer HDDs and SSDs on show strengths in different areas. Our synthetic benchmarks are geared at showing the performance of the drive in an uncached “worst case” scenario, while our real-world traces allow the drive to cache data and better show how the drive would perform during repetitive day-to-day activities. Since the SSHD is really geared towards those workloads, we put more weight on than in this review than we would normally do for traditional HDDs or SSDs.
