Zoned Setup- A more complex read pattern that is much more demanding of the caching algorithm. The overlapped cold-cool-warm-hot data regions IOMeter benchmark is the most stressful on the hot data caching algorithms and so results typically reach performance in the 30,000 to 45,000 IOPS range. The base array in this scenario is generating around 500 IOPS before acceleration, which …

ADDED VALUE During testing,  one thing that struck me was the sound of the drives, once they were loaded with information and being tested. The 4k random read is one of the hardest types of file access for any storage solution, especially Hard Disk Drives. At the beginning of each test, sitting in the room I could hear the sound …

This is the Test Bench and a quick click will display it close up.  As you may have guessed, it truly is no ordinary Test Bench and I have dedicated more hours creating this build than than I care to admit to get it where it is today. Our main focal point in this report will be an array of …

MBR LIMITATIONS In order to ensure that our review went smoothly, their needed to be consideration as to what partitions would serve our tests best as this was definitely not a standard-issue configuration.  This was first discovered when we examined the inherent limitation of the MBR disk partitioning system which is the standard used for the vast majority of drives …

ATTO DISK BENCHMARK V.2.46 ATTO Disk Benchmark is the quickest and simplest method to determine transfer speeds and utilizes the same test methodology as manufacturers in arriving at performance results.  It simply measures raw sequential transfer speeds for both read and write access at various transfer sizes, producing a very easily understood result. This benchmark is by far the industry …

CRYSTAL DISKMARK 3.0.1 Crystal Diskmark is a very flexible benchmark that shows the speed of the drives at various file sizes. All of the smaller file sizes are measured in random access, a key weak point of many types of Hard Disk Drives. With this benchmark we can see the great scaling from the single drive compared to the raid …

WIN7 EXPERIENCE INDEX The Win7 Experience Index (WEI) represents Microsofts method of rating computer systems and, more specific to our usage, provides a storage evaluation through a graduated rating system up to 7.9 on PC components and the system as a whole. This benchmark is built into Windows and anyone can use it by simply typing: Go to Win Orb/All …

Welcome to our follow up of the LSI 9265-8i MegaRAID Card, an eight-port PCI Express SATA+SAS RAID Controller that is configured for 6Gb/s devices. Our first LSI review concentrated on RAID 0 speed and performance and the response prompted our further testing of the LSI in a RAID 5 environment. Take a look as we explore the in-depth the performance …

This is the test bench that we will be using, and it is something that I am particularly proud of.  A quick click on the picture will give you a close up. We are using an array of 8 Micron C300 256 GB SSDs that Micron has provided to make this review possible. As you might have guessed, this is truly …

In testing the 9265, we ran some of the usual suspects for consumer benchmarking to include AS SSD,  ATTO, Crystal Disk Benchmark, and HDtune Pro. We also have ran quite a few tests with IOMeter, and  enjoy the use of AIDA 64 for latency testing as it gives a very good indication of average device latency. The Windows Experience Index …
