Performance
Performance tests as usual are based on a popular benchmarks available around the web. All tests are easy to read and all our readers can easily compare results achieved in our redaction with the results on a home computers. In this way we can check if new drive will really improve general performance.
All tests were performed on a Gigabyte Z97X-SOC Force motherboard using Intel SATA 3.0 ports so again hardware easily available for most our readers.
ATTO Disk Benchmark
As usual I’m starting from ATTO Disk Benchmark as it’s one of the most popular storage benchmarks but also because it’s measuring only sequential transfers.
On the graph we can see maximum read bandwidth of 212MB/s but for the most time it’s about 182MB/s. Both results are really good comparing to the cometitive SSHD from other brands or any HDD. For example Seagate SSHD which I was testing couple of months ago could barely pass 120MB/s in this test.
Write results are lower but are also at respectable level. 90MB/s is enough for everything as data are being additionally cached so users can’t see any delays.
CrystalDiskMark 3.0.1 x64
Moving further to CrystalDiskMark, we can see similar sequential bandwidth results but there are also random transfers that are often more important if you are installing system on this drive or run games or other applications. 12MB/s random 4K read is about six times more than regular HDD can make. It’s not as high as SSD but should offer much better experience while work on a small files than a HDD.
AS SSD Benchmark
AS SSD is a benchmark designed to test SSD but is also good for every other storage maybe except USB flash drives.
Results in this test are close to what we can see in CrystalDiskMark so up to 180MB/s sequential read and 85MB/s sequential write and up to 12MB/s random 4K read. Random writes are not so important because of already mentioned system caching so regardless of what we see in benchmarks, our general experience will be still good.
Anvil’s Storage Utilities
Anvil’s benchmark are bringing us similar set of tests so we can see a mix of sequential and random bandwith tests but also something additional – IOPS. IOPS so Input/Output Operations per Second. This value is mainly important in an enterprise storage devices but is also good to compare performance. All who were testing HDD know that IOPS are the main issue in a server environment. SSDH can’t offer as high IOPS as SSD but the same as random read or write, is couple of times higher than in HDD. That’s the main reason why server manufacturers are more often using SSHD and actually trust this solution.
Toshiba SSHD is offering us quite good performance. It’s noticable higher than mentioned Seagate SSHD and much higher in random transfers than a regular HDD. We can’t expect it will reach speed of any SSD but considering much lower price per GB I think it’s still a good option for all who need a single drive in their PC or laptop.
