Samsung SM843 Pro: Ultra Fast Data Center SSD

2 thumbs up

Our Test Methods: Under each test condition, the Solid State Drives tested here were installed as secondary volumes in our testbed, with a standard spinning hard disk for the OS and benchmark installations. Out testbed's motherboard was updated with the latest UEFI available as of press time and AHCI (or RAID) mode was enabled. The SSDs were secure erased before testing and left blank without partitions wherever possible, unless a test required them to be partitioned and formatted, as was the case with our ATTO, PCMark 7, 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, and waited several minutes for drive activity to settle and for the system to reach an idle state before invoking a test.

IOMeter
I/O Subsystem Measurement Tool

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 for the average end user. 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 another with 4K transfers, 100% random, 100% writes.

All of the drives offered consistent performance in the 4K random write test, with the Micron P400m finishing between the Intel and OCZ drives. Samsung's latest enterprise SSD, however, pulled way ahead of everything else. In our custom workstation test, the Intel drive jumps out to a big lead, with the Samsung and OCZ Vector drives mixing it up for second.

In terms of bandwidth with the two access patters we tested in IOMeter, the Intel and Samsung drives lead the other drives and trade victories. The Samsung drive offered the best 4K random performance, while Intel's drive took the lead in the 8K/80/80 test.

All these graphs in so many SSD reviews all over the Internet is fine and dandy to show a comparison to drives previously reviewed but screen shots of the drive being reviewed is also good to expose some info that is missing or hard to find in the review.

Anvil Storage Utilities is my favorite SSD synthetic benchmarking tool.It gives the screenshot viewer much more info about the system,whether it's the boot drive,the storage driver being used,SSD alignment and the type of data used for the benchmark.

It would be nice to have a screenshot of Anvil Storage Utilities using both compressible and incompressible data.

Since nobody in their right mind would buy an SSD to keep it empty all reviews should show benchmarks with the SSD as the primary boot drive with Windows installed and equal amounts of compressible and incompressible date on the drive.

SSDs perform very differently with data on them especially when the drive is more than half filled.

Benchmarking an empty drive from a different boot drive in Safe Mode doesn't tell anyone how their SSD purchase is likely to perform after they install it in their PC.
