WD or Samsung drives?
Mine are Samsung. I'm kind of off-topic in this thread, my apologies.
WD or Samsung drives?
Uh... what's up with that HDtach STR plot?
It was a logical progression from Bozo's Ovrdrive. :alb:I don't get the relationship between HDTach and the student film about bad drivers. :scratch:
That's what it looks to me like it's doing.Total speculation: Given that it starts around 2,147GB Looks like something in the file system or HDTach is using a long int (max value 2,147,483,647) to store a value and it rolls over and starts at the beginning again.
512MB & 1GB Non-Volatile Cache (with the exception of H700 modular)
*In the event of power interruption, data retention in cache is extended from hours to years
*Introduction of larger cache size: 1GB
Cut-through IO (CTIO)
*Performance boost (up to 2X IOPS performance)
*Optimized for superior IOPS of SSDs over HDDs
*Ideal for small-block random workloads
*Easy to enable
The Dell PERC H700 delivered up to an average of 41% better IOPS performance with internal SSDs than the Dell PERC 6/i
It's LSI 2108 ROC. The perc H700/800 is the re-designed LSI SAS 9260-8i/9280 and can come with either 512MB DDR2 regular dimm (that's what I tested) or 1GB DDR2 with integrated NVRAM cache(no need to have battery).Here's the link of the exact ram chip used in 1Gb version:

I even flashed the card with the firmware for that LSI card into perc h700 with no issues and flashed it backed to Dell's firmware while I was testing the issue I initially had with this card (was detected in windows but not during the post on my second PCIe slot). I tested same drives on intel ICH9R in raid0 and had max speed of only 520MB (max read throughput). I used HDtune, ATTO and crystal disk mark. Basically there's a gradual performance increase going from intel to perc6 to perc h700, with the biggest increase going from 6 to 700. Cache definitely creates some sort of magic. I'm still trying to understand from technical perspective if sata 2.0 device (or combination of devices=raid0 for that matter) can achieve sata 3.0 speed when used on that port ?. And perc H700 is 6Gb capable....but I'm not getting those speeds
Why does a 4-pack of WD 3TB drives cost more than four times as much as a single drive? It makes no sense. :elephant:
Does anyone use the 3TB drive successfully?
The trick there is to simply buy your drives from someone other than Newegg if you're that paranoid over their shipping methods.Maybe because they actually come package decently enough so your drives aren't killed by UPS.
The ICH on some newer Intel boards.

I bought an X58 mainboard in November, so it is probably not supported any more. :lol:
Interesting. When the 3TB drives are connected to the 3Ware 9650SE they show up as 750GB each.
I hope you don't have a 37.5% DOA failure rate like I did. linkHmmm.. This is interesting. Thanks for the quick response! I guess I'll go with 2TB 7k3000s on mine then. I'm hoping the discs will be supported properly.

Looks like LSI issued a firmware update to address that...
