O&O Defrag 11 by: Michael A. McKenney on 5/15/2009
I have a LSI Logic MegaRAID 8708EM2 controller and Seagate 10K Savvio 146GB drives.

Raid 1 benchmarks:
Detailed Benchmark Results
Buffered Read : 1.01GB/s
Sequential Read : 119.73MB/s
Random Read : 128.25MB/s
Buffered Write : 679.29MB/s
Sequential Write : 31.91MB/s
Random Write : 31.21MB/s
Random Access Time : 1ms

I expect the 15K.6 to be 30% faster.
RE: SAS Drives... by: Theo Valich on 5/15/2009
It seems that with every IT evolution, I jump forward, then go backwards, then go forward again.
Had SSD back in 2006, and it really worked like a charm, no slowdowns at all - but it was SLC-based. SSDs will definitely start to dominate users who demand top speed, and in workstations, 15K really isn't an option - it just screams. Then again, servers won't mind... they scream in a silent room anyways ;)

What defrag tool are you using?

Regards,

Ed.
SAS drives are fine for now by: Michael A. McKenney on 5/15/2009
I am looking at the new Seagate 15K SAS drives to replace my 10K SAS drives. I like to defrag my hard drives to keep performance.
