So I have a few HDDs, all at 7200 and all are SATAII/SATA-300/SATA 3.0Gb/s rated...
I have a MSI 790X-G45 SATA 3.0Gb/s Mobo
The fastest transfer rates I can hit are 167Mb/s. I can only hit these numbers between one brand-new ST32000DM001 Seagate Barracuda (64MB Cache) and two RAID0 Seagate Constellation ES (32MB Cache) drives, and only even then when I make sure the two RAID0 Constellations don't share the same channel.
That's surprisingly only when I am writing TO the Constellation Array from the Barracuda. If I am reading off to the Barracuda the Array settles down at around 130Mb/s. I know transfers are set by the slowest drive, so either the write rate of the Barracuda is lower than it's read (by 35+ Mb/s?) or it's the reverse for the Constellations.
I checked the channels between these three drives as well, and regardless if the Barracuda shares a channel with either Constellation, it still stays at 130Mb/s when writing to the Barracuda.
-But-
Is this all I can get out of these drives? I have brand new SATA cables as well (though in most cases that won't matter).
I did a Google crawl and was inundated with data. I can only assume this topic has been hit dozens of times before, so I apologize in advance.
Is it that while my Mobo and SATA connections themselves can go "up to" 3.0Gb/s my actual HDDs top out at 170Mb/s?
Does anyone actually know what the maximum (even theoretical) Read/Write rates are of 7200 SATA 3.0Gb/s HDDs?
Another Google crawl on the subject revealed more obfuscation.
Ideas gents?
Thanks!
