Intel SSD 545s Series Solid State Drive Review: One Of The Best SATA SSDs Available

Intel SSD 545s - Test Setup, IOMeter 1.1, Compression

Our Test Methodologies: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a separate drive used for the OS and benchmark installations. Out testbed's motherboard was updated with the latest BIOS available at the time of publication and AHCI (or RAID) mode was enabled.

The SSDs were secure erased prior to testing, and left blank without partitions for some tests, while others required them to be partitioned and formatted, as is the case with our ATTO, PCMark, SANDRA, and CrystalDiskMark benchmark tests. Windows firewall, automatic updates and screen savers were all disabled before testing. In all test runs, we rebooted the system, ensured all temp and prefetch data was purged, waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test.

As we've noted in previous SSD articles, though IOMeter is clearly a well-respected industry standard drive benchmark, we're not completely comfortable with it for testing SSDs. The fact of the matter is, though our actual results with IOMeter appear to scale properly, it is debatable whether or not certain access patterns, as they are presented to and measured on an SSD, actually provide a valid example of real-world performance. In other words, the access patterns we tested here may or may not reflect your particular workload. That said, we do think IOMeter is a reliable gauge for relative available throughput within a given storage solution. In addition there are certain higher-end workloads you can place on a drive with IOMeter, that you can't with most other storage benchmark tools available currently.

In the following tables, we're showing two sets of access patterns; our custom Workstation pattern, with an 8K transfer size, 80% reads (20% writes) and 80% random (20% sequential) access and a 4K access pattern with a 4K transfer size, comprised of 67% reads (34% writes) and 100% random access.



The new Intel SSD 545s 512GB drive we tested performs wells here. It offered consistent performance at various queue depths, and finished about in the middle of the pack with the 4K, 100% random access pattern. It moved up a few rungs in the 8K / 80 / 80 test, which incorporated some sequential transfers, however.


The overall bandwidth scores at the highest queue depth reflect what we saw in the charts above -- The Intel SSD 545s series drive we tested finished near the top, trailing only the Samsung drive.

AS SSD Compression Benchmark
Bring Your Translator:
Next up we ran the Compression Benchmark built-into AS SSD, an SSD specific benchmark being developed by Alex Intelligent Software. This test is interesting because it uses a mix of compressible and non-compressible data and outputs both Read and Write throughput of the drive. We only graphed a small fraction of the data (1% compressible, 50% compressible, and 100% compressible), but the trend is representative of the benchmark’s complete results.



The compressibility of data being transferred on the Intel SSD 545s series drives has no impact on performance. Data rates remain flat and smooth regardless of the compressibility of the data and the new Intel drive performs among the best in this test, especially the read tests where the 545s topped all of the other drives.
