Just FYI, after a full weekend of work, everything is working as expected here. 3 Samsung HD103UJ in a Debian 4.0 software-controlled RAID-5 array :
Hardware specs :
- Motherboard : Gigabyte
- Chipsets : Intel 945P and ICH7
- Processor : Core 2 Duo E4300
- Drive : SATA DVD-R from LG
All the disks first went through a full RAID-5 synchronization that took nearly three hours, with no errors. After that, we did a pretty extensive R/W test during nine more hours (based on lots of randomly-generated 1GB files), with a md5 check at the end on all the files. Not a single error. Finally, we copied 466 GB of real data into the RAID-5 array, with no errors either.
The disks are recognized by the Debian SMART monitor (lenny version - be sure to update, and be sure to check the SMART option in your BIOS menu of course), AAM has been successfully activated (AAM 128 - quietest mode - very impressive !
), all the temperatures are OK. See the pictures : disks outside the PC, with no aircooling at all, their temperatures were 37Â°C to 40Â°C during all the intensive testing process (just 3Â°C increase after all the hours of R/W).
FYI, we are using a 256-bit encryption method (luks) all over the array (every single byte of data is encrypted, a passphrase is required to access the info). That means everything has to be encoded/decoded in real time by the processor, thus dramatically slowing the performance of the array (even with a Core 2 Duo). But like I previously said, performance is not an issue here, this array is only for storage purposes. The R/W array performance with real-time encryption activated is 40MB/s, which is good for us. The R/W array performance without encryption is 180MB/s. Finally, the R/W performance of a single drive is about 100MB/s.
These disks are everything you can expect. They are good, they are reasonably cheap (in the US), they are fast, and we haven't encountered any problem with all the nine
we have bought from NewEgg. I thought it was worth the report, so people can stop whining and complaining. So if you are getting any software problems with these drives (drives not recognized by a software or a particular chipset, errors indicated by a software...), be sure to update your software or your BIOS first, or contact the developers and wait for fixed software/BIOS versions, before incriminating your drives. Generally speaking, most computer problems are not caused by hardware products, but by people who haven't succeeded in using them with the right software. I'm not accusing anybody here, I'm just saying that we need to be careful before making strong assertions like "the new F1's are not ready", etc. Thanks in advance.
So far so good...
