Adaptec Series 6E Unified Serial SATA/SAS RAID controllers deliver the robustness of hardware RAID and the Adaptec RAID Code, enterprise class management features, and full OS support -- including open source drivers for Linux and FreeBSD -- into the entry level RAID space. Delivering the same 6Gb/s performance of the Series 6 controllers, the Series 6E are optimized for the platform where a Series 6 controller would not fit in from a price, form factor or host connectivity standpoint.

Series 6E controllers support SATA and SAS devices, and have been qualified with the same systems, motherboards, backplanes and drives as Series 6 controller. They include the same drivers, BIOS and storage management tools as Series 6 controllers and do not require additional training or qualification. Series 6E controllers are thoroughly tested with entry-level storage devices for desktop use and entry-level server platform, workstation and motherboards most typically used for basic server, performance workstation and industrial PCs.

  • newegg I/O Connectivity and Data Protection With its entry-level price point, Adaptec 6805E can be used as a connectivity product, with support for up to 8 SATA and SAS devices, and 128MB of DDR2-800 MHz DRAM cache for device acceleration. At the same time, the Adaptec RAID Code (ARC) delivers maximum reliability with RAID levels 0, 1, 1E, 10 and JBOD. ARC also offers RAID Level Migration (the ability to easily migrate RAID levels), Online Capacity Expansion (expand capacity without powering down the server), and Copyback Hot Spare (when a failed drive has been replaced, data is automatically copied from the hot spare back to the restored drive).
  • newegg Hybrid RAID With Hybrid RAID 1 and 10 the Series 6E controllers offer maximum performance and reliability by combining Solid State Drives (SSDs) and Hard Disk Drives in a single array. By performing read operations from the fastest SSD and write operations on both the SSDs and HDDs it offers tremendous performance gains over standard HDD RAID arrays. By combining SSDs and HDDs it offers the benefits of both technologies and allows a better cost per GB ratio than comparable SSD only arrays.
  • newegg The Case for Cache The fastest way for a RAID controller to fulfill a read or write request is to serve data out of its cache. Savvy network administrator knows that enabling the RAID controller cache offers significant performance benefits, such as reduced latency in I/O request, bandwidth and queue depths that surpass software application limits, and on-the-fly parity calculations on sequential writes.
  • newegg Intelligent Power Management Intelligent Power Management (IPM) slashed power and cooling costs by up to 70% using intelligent I/O caching combined with disk drive power savings via standby and power-off modes.

5 out of 5 eggsGreat Driver Support

Pros: I installed this card on a server I built that includes a SuperMicro motherboard X9SRL-F ATX. And, the operating system (OS) is VMware ESXi 5.5. Adaptec provides drivers that supports this OS and I found it to be most compatible. This card performs very well. The heatsink has four threaded studs, one on each corner to mount a cooling fan right on the heatsink. I purchased a Noctua A-Series NF-A4x10 40mm cooling fan to mount on the heatsink. The specs for the fan screws are: 4 x (M2.6 x 12L) screws. This size screw is very hard to come-by and I understand this size is a Chinese metric. I never heard of a Chinese metric. Anyways, a hobby shop was where I found screws of size (M2.6 x 10L) and they worked very well.

Cons: None

Other Thoughts: Be sure to purchase the this card kit because it includes the proprietary cable. The stand-alone card for less money does not.

1 out of 5 eggsNo good at all!

Pros: Not a bad card, except it does not work in my motherboard.

Cons: I got this card to change from my Bios raid to a card raid because I can not control the bios raid. I have a Gigabyte GA-990FXA-UD5 motherboard and the card fit nice. All cables were hooked up. Went to boot and it seen the card no problem. I went into raid to set up a raid and it seen all the drives, however when I went to activate the drives it would show one gone, then two gone, and the LED's on the case, I have hot swap drives were going crazy. I proceeded to re-install WIndows Server 2012 R2, which the cards works with, and I went to website and got the drivers and firmware update, still did not work, RMA the thing this morning. After reading the other posts out here, it seems that Gigabyte does not work well with Adaptech Raid Cards, shopping for a LSI today.

5 out of 5 eggsBest for price

Pros: Reliable. Updates flawlessly. A lot of info from manager. Easily manageable. When you know a bit about RAID and read the manual as should every new owner of that kind of material, all is easy to configure. Since 2012, the card works every day and never had flaws, never lost performance, etc.

Cons: None I could say.

Other Thoughts: I have this on my home setup, but can definitely recommend for small business use.

1 out of 5 eggsWon't work with video card

Pros: Capabilities for the price

Cons: I have been an Adaptec and Nvidia customer for a long time. I use multiple monitors. In now my third computer with both an adaptec RAID card and Nvidia card, the drivers will not allow the computer to come out of sleep mode with both the Adaptec and Nvidia cards installed. I have to reboot every time.

Gigabyte has helped me isolate the problem and it is clear that the problem is with the Adaptec firmware or driver. Adaptec, however, has a laughable process with a non-technical person running it ... and she said "it could be months" before it will be fixed. She said this before she even was able to identify the problem (although she admitted to similar problems with previous Adaptec cards.

4 out of 5 eggs

Pros: this card will run HOT, just make sure you have good airflow or to make you keep it cool, attached a 40 mm fan onto the heat sink. Make sure the fan is thin so that it will not conflict with adjacent slots.

Cons: run hot, vendor should have included fan as part of the package

5 out of 5 eggstemps for this card!

Pros: this is another pro. For those who have written reviews before for this card, I found the max operating temperature for this card. If you google "9805e temperatuires", you should get a result from a adaptec for temperature requirements for pretty much every series of pci-e raid card made by adaptec. These guys are meant to run like a Nvidia Fermi video card even without a fan. Their max temp is 100C or approx 230 F. That awfully freaking high for a consumer pc! It's not that I wouldn't get a cooling fan for it but I don't think it's needed. Maxview starts warning when the temps get around 85c.

Cons: N/A

Other Thoughts: I don't own this card anymore as you can tell from my 2nd review.

5 out of 5 eggsupdate on my last review

Pros: see 1st review.

Cons: about the raid bios. It's UEFI friendly meaning it works with UEFI biosf for the motherboard/. One thing, you have to set your UEFI bios on your motherbostf to boot storage controller in legacy mode. If you try UEFI mode, the raid cards bios doesn't get loaded into either nvram or the motherboard bios itself.. And the raid card has a text bios, not a gui bios. And for those loving windows 8/8.1 fast booting, yes the card fast boot once the raid bios has been loaded. For the raid bios to load,it takes approx. 30 seconds.

Other Thoughts: if money permitted, I would upgrade my mb to a g1.sniper 5, add a 3rd video card, use the creative sound onboard and get a lsi 9371-4i card.

This is what I am using right now:

Intel Xeon E3-1245v3 3.4 ghz quad core (got it for $299 at xmas on the egg, now $355)
Gigabyte GA-Z87X-UD3H mb
8gb of patriot viper 2 ram at 1866mhz
2x Zotac gtx 770 amp video cards
Antec HCG-850M psu
2x OCZ agility 3 ssd's in raid 0 (using marvell controller, intel controller on some 8 series mb's don't like sandforce ssd's)
sb recon 3d pci-e
pioneer bdr-208

5 out of 5 eggsnice little hardware raid card!

Pros: nice little hardware raid card. for those using snb, ivb or haswell, this is a nice on some motherboards. My brother and I have a pci-e 3.0 x8/x8 with a pci-e 2.0 3 times x1 with a x4 slot that disables the two x1 slots between the x16 3.0 slots. Even for those using a pci-e 3.0 x8,x4,x4 this is also nice. I am using a ga-z87x-ud3h and it works fine in terms of the driver. see cons about maxview manager software. Is a UEFI motherboard friendly card. see cons about the raid bios.

Cons: maxview storage manager is a bit poop when it comes to tweaking and cleaning your pc. One, you have to only install the driver for MEI, if you install the whole MEI suite, maxview storage manger (internet browser based) complains that the CIM server service is not running when trying to login into the manager. Even if you restart the CIM service, ,maxview still poops out. And if you are tweaker like me who wants to squeeze all of the speed out of your system, maxview may poop out on you again with a maxview server service not running. Again, you can restart the maxview server service and it still won't work. Had to chuck out the card because of this.

Other Thoughts: The card has 4 screw holes for a 40mm fan. Looking to repurchase the raid card in a couple of months and buy a noctua 40mm fan along with a rosewill thor v2 case. Why such a big case. Because with the fan installed, it makes the card a dual slot card technically (maybe 1 1/2 slots). Anyhow, you can't use this with fan in a atx case and motherboard because there is not enough space for a 40mm long x10mm wide fan.

5 out of 5 eggsHigh Performance Controller

Pros: Fast, 8 6G drives, Inclueds Cables

Cons: Does not include a fan but it needs one.

Other Thoughts: Rated 5 because of performance. I found Raid 1E to be much faster than a single disk so that's what i would recommend using.

Adaptec offers an optional fan kit. I had some 40mm fans so i used one of them. You don't need much airflow so any quiet 40m fan will be good. Heatsink is threaded so you just bolt it on.

I thought that the included management software was mostly useless. For home computers don't bother installing it. The BIOS has all the options and it's easy to use.

I also downloaded the latest driver (Windows 7 64) and have had no problems.

Adaptec offers this in a 4-drive and 8-drive version and I would recommend this to anyone needing a high performance RAID controller.

2 out of 5 eggsNo Support for RAID 5 or 6

Pros: -

Cons: The Adaptec 6805E does not support RAID levels 5, 5EE, 6, 50 and 60. The Adaptec 6805 (without the E suffix) does support these RAID levels. However, the 6805 costs about twice as much.

Other Thoughts: I bought the 6805. However, I almost bought the 6805E by mistake.
