Great for mechanical hard drives
04/27/2012
This review is from: Adaptec RAID 6405 2270000-R 6Gb/s SATA/SAS 4 internal ports w/512MB cache memory Controller Card, Single
Pros:
Assuming a proper cable is purchased, SATA III hard drives can connect at 6 Gbps.
Good compatibility with older motherboards. I used an Asus P5E x38 motherboard.
Using mechanical hard drives, this card outperforms competing cards in RAID 5.
Using a RAID card makes it possible to transport an array to a different machine with data intact, not likely with motherboard RAID.
512 MB cache supercharges smaller file transfers and assists in larger file copies. See other thoughts for benchmarks.
The card's onboard RAID chip performs the processing necessary for RAID, without stealing cycles from the CPU like cheaper cards or software RAID.
Cons:
Boot time - With card installed, takes about 30 seconds longer until logon screen appears.
Does NOT come with cables. (Its cheaper to purchase the card and cables separately anyway.)
Requires additional cooling than the built-in heatsink. I used Vantec Spectrum Fan Card (Model SP-FC70-BL) which by default aims the flow of air perfectly at the card's heatsink.
Seems more optimized for mechanical hard drives than SSDs.
Required about 27 hours to initialize 6TB RAID5 array with three 3TB drives.
Overall Review:
I purchased the card to create a RAID5 array on an older PC using three Seagate 3TB hard drives (STBD3000100). 64 Kb stripe size, used default allocation unit size in Windows.
Plugged the card into the 2nd PCI Express x16 slot.
Any reviewer should mention their motherboard and model(s) of hard drives and whether it all works together or not, as compatibility info is very valuable to know.
I purchased the StarTech SAS8087S450 SAS Cable which saved money over buying the "kit" that includes the card with a cable.
Warning: Western Digital drives are known to drop out of RAID arrays unless they are the WD Enterprise (RE4) series!
Benchmarks using CrystalDiskMark 3.0.1 x64:
4000 MB file size
Sequential Read : 300.667 MB/s
Sequential Write : 297.637 MB/s
50 MB file size
Sequential Read : 1312.676 MB/s
Sequential Write : 1284.467 MB/s
Not a typo! Probably due to 512MB cache on the card.
