4 out of 5 eggsGreat Line Of Cards

Pros: Solid Adaptec Performance & Support (both customer support and OS support). Supports most of the popular RAID levels. Low profile design fits in smaller chassis. 512MB of Cache and a dual-core processor.

Cons: Slightly dated line, only supports 3-Gb/s. Limited SSD support for "caching drives". A little pricey considering the 6xxx series is available for about the same price (with 6-Gb/s support)...

Other Thoughts: This particular model supports 4 internal drives and four external drives. Fits great in my little NAS (HP Proliant N40L). I bought this second-hand at a GREATLY reduced price, otherwise I probably would have bought a different model (and maybe brand)... I also have experience with Dell/LSI and Areca cards and Adaptec has always been my favorite.

1 out of 5 eggsPoor performance in RAID 0

Pros: Nice LEDs

Cons: Half of LSI MegaRAID 9260 performance in RAID 0. Non-existent tech support. Even techsupport answering is full so I could not leave the message. I guess too many problems and slow help.

5 out of 5 eggsSuperior Quality Card. FAST - 1200Mb/sec!

Pros: Adaptec does a great job at creating a top of the line RAID card.

To start, it has the newest Intel IOP348 (Dual 1.2Ghz Processor) and 512MB of cache. You can't get much better then this.

I'm running a small SATA II RAID 0 (on the internal SF-8077 port) and getting 1200Mb/sec. I' now working on my external RAID 5 Array.

I went from buying bad SSD's trying to get rid of my hard drive bottlenecks (99% of them are bad except the Intel's - and those are overpriced) to buying a good RAID card and sticking with SATA II drives (I'm using Western Digital) and obtaining speeds that are just insane.

The features in their BIOS and software (Adaptec Storage Manager) offererd are top of the line. It BLOWS AWAY a brand new Areca and they consistantly update their firmware on a regular basis to ensure that all hard drives (SATA, SAS & SSD), motherboards and SAS backplanes are supported.

If your looking for quality, speed, reliability and support, then look no further.

Cons: Zero.


Buy one for each of your computers.

Other Thoughts: Adaptec also has the best sales and support that I've dealt with.

From sales all the way to support, they know what they're doing. I own and have owned top of the line Areca, LSI and Highpoint (yikes!) cards and out them all them I'm sticking with Adaptec.

I'm hoping they update their firmware for more SSD's soon but I have a feeling they haven't because most SSD's either have a bad controller, no support for Trim/Discard and just aren't ready yet for prime time.

Putting this card together with some good SATA II drives (SAS if you really want speed) is all you need to get rid of your hard drive bottlenecks.

You can have the lastest and greatest Intel Quad CPU's, tons of RAM and a great motherboard, but without removing the bottlenecks on your hard drives (without a good RAID card) then you haven't experienced what true speed is.

Buy one, you won't regret it.
