Pros: Good price for a Sata 6Gbit card that runs RAID 5. Good Tech Support for Issues. Simple and Easy to use Web Gui

Cons: Not Plug and Play Install. Complicated Process to reflash the card's firmware to get it to not boot with a Out of Memory Error on the Bios boot. Issue was resolved, but the trouble cost them an egg. It would be nice if they had a hot line for issues like this.

Overall Review: I bought this card to setup a RAID 5 array with 3 x 3TB WD Red drives. I have an ASUS P6X58D Premium Motherboard, with an Intel i7 920. I plugged the card into an open slot and booted. System Froze at the Cards boot with a message Out of Memory in the top left corner. After Contacting High Point through their website on Friday, they got back to me on Monday. They had me boot with the card plugged in with no drives attached. When the Card's Boot screen appears press End to skip it. When the OS boots update the driver using the one off their website. Just a warning for some reason when I downloaded their driver zip, and extracted it, all the files were green inidicating they were encrypted. When trying to update the driver I would get an Access Denied message. I had to goto properties on the drivers, advanced, and then uncheck encrypt. Then I was able to update the drivers successfully. After that I installed the Web Gui and used it to update the Card's Firmware. Then I shut down the computer, plugged my drives into the card and booted. System came right now, I used the Web Gui to configure my drives into a RAID 5 array. Then rebooted again and windows recognized the array, and allowed me to setup the partition. Currently migrating my data to the Array. I have 2.5 TB of data on a WD 3TB Green Drive, that I am migrating to the RAID 5 array consisting of 3TB WD red drives. Access times and write speeds seem good. Transfer speed started off at about 120 MB/sec writing to the array, but has now dropped to about 71 MB/sec as I hit patches of smaller files. The setup was more tedious than I had wanted, but I have had good experiences with 2 of their other products in my servers, so I was willing to try them for the 640L. Glad to know it wasn't some compatability issue. For others having problems with their cards use the support section of their website and contact them. It might take a day or 2 for them to get back to you, but they will help you. Granted I feel this should be easier than this, but in the end the card worked, and it performs much better than using the windows built in Software RAID options.

Pros: Works fine on Ubuntu 9.10 and Windows 7 64 bit. Up to Linux-Headers-2.6.31-14 and that's all the support you will get from HighPoint. You have to modify the sh. your self for higher headers, i.e. 33.. or newer Ubuntu releases.

Cons: HighPoint doesn't support you in anyway with this product. Drivers don't keep up with new linux distros. Windows 7 is no problem.

Overall Review: Ubuntu Server 9.10 64bit is the best OS for NAS so far.

Pros: It's fast, even a six TB array only took about 18 hours to setup fully. Easy to configure, very easy to understand with the slightest knowledge of RAID Arrays. Works in Windows 7, Also works in Ubuntu 9.04, 10.04, 11.04 and 12.04.

Cons: Ubuntu Drivers must be installed, but once installed as a package (You need to find it as a package) it'll port from version to version. I installed this on Ubuntu 9.04 and have upgraded from version to version without issue, or without re-installing the drivers.

Overall Review: While I would love the Ubuntu drivers to just work out of the box, it took me (First time Ubuntu User at the time) about 2 hours to work out what needed to be done, what questions to ask Google, and how to install it. Since then I have not had a problem using it. Although I do only use it as a storage Array, I do not have Ubuntu installed on the Array.

Pros: Load command set gives this raid card the edge for me.

Cons: don't like the sata connection layout

Overall Review: another reviewer here at Newegg, David C. has made this card the perfect raid card for my system, as it is being used as a secondary raid-10 support unit. The load command that he indicated, will eliminate the bios load of the card, which works perfect for my hardware setup and speeds up loading of the overall system.

Pros: I was running a raid5 off my motherboard was only getting 20 mb write and 10 read. Really bad speeds. Purchased the card and was drastic improvements. running crystal disk I got 150 write and 100 read. The card is very good

Cons: None so far

Overall Review: The card is very easy to set up. Recently reformed and all I had to do to get my pc to recognize it is install the drivers right off the cd. As soon as I installed the drivers my computer recognized it, everything was back, even the drive letter was the same. I reformat often so knowing that my 8TB raid is safe is great.

Pros: I owned both RocketRaid and Rocket 640L. RocketRaid 640L is based on Marvell 88SE9235 Rocket 640L is based on Marvell 88SE9230. Both are supported out of box in Apple Mountain Lion. Marvell 88SE9235 is a simplified 88SE9230 chipset in functionality even it has a big number. that's why Highpoint combined its own raid function with 88SE9235 to make RocketRaid 640L. Rocket 640L is based on Marvell's own raid functions

Cons: CTRL + H to enter RocketRaid 640L bios screen -- highpoint bios CTRL + M to enter Rocket 640L bios screen -- marvell bios, RocketRaid 640L bios slows down boot process comparing with Rocket 640L. I hope Highpoint can improve it with firmware update for RR640L in future.

Overall Review: In Mountain Lion, Raid 0 under Rocket 640L shows as a real RAID drive. Raid 0 under RocketRaid 640L shows as a Parallel SCSI drive. But both are bootable for Mountain Lion.

Pros: Low Cost, but you what you pay for.....

Cons: Upgraded from 2310 to 640L. Array HD's just needed to be connected and it was ready go.... Sweet, but after 10 months the 640L just flat out failed, no BIOS boot up screen.. just died. Warranty is for one year - repair only - ? Customer Service on the web site is not helpful. WEB Management software caused BSD after reinstalling old 2310. Had to uninstall Web Software and hack the register to remove old 640L driver entries to recover.

Overall Review: The whole point of RAID 5 is fault tolerance. No one, home or professional industry, needs a RAID controller that fails out of the blue. HighPoint used to be a company with a good reputation, but after this RocketRAID 640L failure, I will NEVER use their product again. I have been using HighPoint RocketRAID controllers since 2005 and never had a failure until I installed the 640L.

Pros: Seems to work fine. No drives have failed B"H, so I don't know if it will alert me to a failure. Running on Windows 8.1

Cons: Boots are slow.
