  • Seagate Desktop SSHD 4TB ST4000DX001 Consumer HDD Review

    Conclusion  SSDs have reached their peak in popularity, with nearly every system now shipping or being built with them. Mechanical hard drives still hold the position of capacity, and while SSDs attempt to close this gap with emerging technologies like TLC and 3D NAND, drives like the SSHD from Seagate offer a bridge between high capacity and high performance solutions. In testing, we found the 4TB SSHD to scale quite well in random read operations, while random write carried a burst of performance followed by linear results around 330 IOPS. Sequential read performance was a bit of a misnomer for both the 2TB and 4TB SSHDs as it reached only 55 MB/s. Write performance on the other hand was chart topping at 177 MB/s, beating out the 2TB solution by 20 MB/s. Workload testing was up and down for the 4TB SSHD, as the database workload presented a challenge for the SSHD. However, throughout the rest of workload testing, the 4TB SSHD was at the top of the charts and cemented itself as a great workstation solution reaching 202 IOPS at QD32. Power testing revealed the 4TB SSHD used a just a touch more power than the standard solution in random read and write, while sequential workloads had each of the drives within 0.14 watt of each other.  PRICING: You can find the Seagate 4TB SSHD SATA 6Gb/s 64MB Cache 3.5-Inch Internal Bare Drive (ST4000DX001) for sale below.

    Seagate Desktop SSHD 4TB Review

    Plus

    • Better performance than traditional HDDs
    • Hot files stored in 8GB NAND flash
    • Good performance during mix workloads

    Conclusion The Seagate Desktop SSHD is a 3.5 inch hybrid drive that combines HDD capacity with SSD performance. Designed for desktop PCs, workstations, and high-performance DAS devices, the Seagate drive is equipped with 8GB of NAND flash, allowing hot data to be kept on flash storage while less active data stored on the HDD. As result, consumers will experience speedy system boots, faster load times, and increased responsiveness compared to traditional HDD. Though this is nothing unique for an SSHD, the Seagate Desktop SSHD is fairly cheaper than its WD Blue comparable, going for roughly $50 dollars less ($150 vs. $200 for the 4TB capacity). Diving into its performance, the two hybrid drives we compared posted results very similar to each other, though the Seagate offered better overall transfer speeds during mix workloads. In our 2MB sequential transfer benchmark, the Seagate Desktop SSHD measured 156.28MB/s read and 154.28MB/s write while random speeds of the same file size reached 63.64MB/s read and 73.49MB/s write. In our consumer real-world benchmarks, however, the Seagate drive was handily beaten by the WD Blue in the HTPC scenario. Here, the Seagate SSHD posted just 67.21MB/s, 904 IOPS and 8.8ms in average latency for the latter compared to the WD Blue’s 94.05MB/s, 1,265 IOPS, and 6.3ms. Gamers should certainly take note of our gaming profile benchmark, as results showed a massive increase to 93.98MB/s, 1,749 IOPS, and an average latency of 4.5ms compared to the WD Blues's recorded 64.30MB/s, 1,200 IOPS, and 6.6ms.

    Utmärkelser:

    Fördelar:

    • Vettigt utrymme per krona
    • potentiellt bättre prestanda med tiden

    Negativ:

    • Halkar efter många ""vanliga"" hårddiskar i samma prisklass.

    Omdöme:
    Desktop SSHD ST4000DX001 erbjuder mer lagringsutrymme per krona än sitt 2-terabytessyskon, men ärver samtidigt mycket av vår kritik mot den mindre disken. Den utlovade ""SSD-lika"" prestandan ser vi knappt röken av, och faktum är att 4-terabytesvarianten överlag presterar sämre än sitt mindre syskon. Tanken är dock att disken ska prestera bäst när den ""körts in"" och kunnat lagra rätt information i sitt cacheminne, så det är inte omöjligt att resultaten förbättras med tiden. Direkt ur lådan finns det dock bättre alternativ i den här storleksklassen.
