Western Digital Elements 2TB/1TB USB 2.0 speed test
I had someone ask me to benchmark my WD 2TB elements drive. It might be useful to someone else, this is running on USB 2.0.
ICH9R Fake Raid Failed when Reinstalling OS DISC?
Hello, if you’ve read anything on my blog, you’ll note that I had a 6 x 1 TB HDD SATA raid going through my ICH9R ABIT IP35 motherboard. I recently decided to reformat the ‘server’, and was told by a few that I should be able to reformat the OS drive (separate from the array), and I would not have any issues. So ahead I went … reinstalled OS, got into windows for the first time, and noticed the array was bjorked.
The array had gone into a failed state, and decided to pull 1 drive out of the array as well. I tried removing the 1 drive, re-adding it as a spare, but it would not take/rebuild. I used about 14 different recovery software applications (get data back, undelete, raid recovery, ubuntu live disc, R-Studio, etc) , over the span of 4 days and I could only recover 1/6 items I lost. I was hosed, as a last resort, I decided to rebuild the array, EXACTLY how it was prior to losing the data.
What I did was delete the entire 6 disk array, and re-built the array as I had done before this fiasco. My steps are a little more technical, these are assuming you know how to set up your own raid. If you need any more help, you can comment and i’ll respond.
Step 1 ) Remove array, via option 3 in CTRL – I
Step 2 ) Recreate array with the exact same HDD’s as before
Step 3 ) Use the exact same options as before, raid 5, 64KB strip, etc
Step 4 ) boot into windows
Step 5 ) Go to Disk Management
Step 6 ) It will ask you to specify the GPT or MBR, select the option you previously chose
Step 7 ) Go through the options, but do NOT format the disk
Step 8 ) Use Getdataback, or some other NTFS recovery software
It took about 5 minutes for GetDataBack to show me my entire file structure, and recover ALL of my data back, 100%.
This is all assuming you have NOT done the following :
1) formatted your hdd
2) raid 5, with ICH9R controller – fakeraid
3) you did NOT write any data to your hdd’s
4) technically, this should work with 5 out of 6 HDD’s, or 2 out of 4, etc for a raid 5
I did not think this would work, but boy was I happy I tried it.

ICH9 + 6 1TB Seagate (ST31000528AS) in a RAID 5
Hardware :
Motherboard : Abit IP35+ICH9
CPU : E8400
Memory : 2GB x 4 OCZ DDR2 running @ 399MHZ (5-5-5-18)
OS Hard Drive : 1 x Seagate ST31000528AS
Raid Hard Drives : 6 x Seagate ST31000528AS
Raid info : RAID 5 64KB strip
PSU : Antec Basiq BP430 430W
Software :
OS : Windows Server 2008 Data Center Edition R2 x64
Intel Matrix Storage Manager Driver Version : v.8.9.6.1002
Benchmark : ATTO Bench32 v2.41
Here are some photos of the box, not the best quality (iPhone), but you get the idea :
Here are the benchmarks with write back-cache on
Now here they are with benchmarks with the write back-cache off
Overall, a great little set up, where I did not have to purchase a RAID card, the ICH9 was plenty fast for my home storage. I run it with write-back cache on, for the obvious reason. I would see sustained copy (When I want to write a file from my Windows 7 box to my NAS box) speeds of around 120MB/s, bursting to about 170MB/s. I have played 48GB movies off the NAS streamed to my PS3 with no hitch (via Ehternet).
I have been running this set up for a little over 5 months now with the 430W Antec PSU in an Antec 300 case. No drives have dropped from the array, I have not had to rebuild at all. I have zero errors in the read/write area as well so all is well. I have been adding/removing movies/media/files/storage/backups from that array since it was set up and running. I have a 7th ST31000528AS running as my main OS Hard Drive, so the NAS is purely for storage.
For reference, you can get ICH9 beta software/drivers from this website :

Very fast drive, very comparable to the INTEL X25-M G2 80gb
