IOMeter v2006.07.27 – IOps
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 – since then it got wide spread within the industry.
Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at SourceForge.net and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.
Here we see the longer seek times and increased rotational latency take its toll. To put it simply, these drives are better suited for mass storage and fall behind the Raptor pack in all benches. Of interest is that despite the slower RPMs, the GP drives are surprisingly close to the Caviar SE16.
The 2TB EADS model has 32MB of cache, twice that of the 1TB EACS models. Despite the longer seek times, the WD20 is able to surpass the WD10’s at queue depths greater than 16.
I learned a lot here but have
I learned a lot here but have not yet been able to open my case. Fortunately, I’ve lost no data. All my losses have been the backups of data on internal drives. Ironically, the backup drives failed, never the drives they were protecting. I intend to buy a replacement, but never again a Western Digital. I have two Maxtors running four & two years respectively. My next purchase will be another Maxtor.
