Cables are very flexible and it really helps when setting things up. Card has more features than I need, and it's priced well.With write caching disabled, may as well be on dial up to transfer files. All tested with HD utilities from the server, not through the network. I hope it's just an issue with the WD Red drives- I expected more from a standalone RAID controller, even if it is a lower end unit than the commercial grade stuff many of the IT admins here use.I wish I had bought the card with two cable adapters so I could better implement RAID the configurations this product offers.Supported in FreeBSD and Linux kernels.Making sure firmware up to date is a must. But these are to be expected and are definitely not show stoppers.First with 4x WD Raptor in RAID10 -- great. Then 4x Hitachi 2GB in JBOD for FreeNAS -- great. Now 4x Intel SSD in RAID0 -- great!Never had a single hick-up.Four ports with memory caches for this price is incredible. Good performance.It looks like this is the same card as the 8 port, but would have one more port with another four connections on it.If you are using Windows it is tough to justify a more expensive card. If you are using Linux or VMWare you may want to pursue a major vendor card.Has performed flawlessly. Many of the other PC components including the motherboard have been replaced while the card just keeps on humming.I have had to rebuild the box due to a failed motherboard and a failed OS disk drive (not connected to the card). I've changed OS's 3 times (Win2k then Linux then Win2k8R2), swapped out 2 drives and re-partitioned the array once all without a hitch. In all this I haven't lost a single iota of data using this array.I have been running a RAID 5 array since 2010 using WD RE3 drives. Not one hiccup or any other issue.http://columbuscigar.com/images/3ware-9650-manual.pdf Email of alerts is a great feature since I am rarely at this site.

This section organizes information about RAID concepts and configuration levels into the following topics: RAID Concepts on page 4 Available RAID Configurations on page 5 Determining What RAID Level to Use on page 11 The following concepts are important to understand when working with a RAID controller: Arrays and Units. In the storage industry, the term array is used to describe two or more disk drives that appear to the operating system as a single unit. When working with a 3ware RAID controller, unit is the term used to refer to an array of disks that is configured and managed through the 3ware software. Single-disk units can also be configured in the 3ware software. Mirroring. Mirrored arrays (RAID 1) write data to paired drives simultaneously. If one drive fails, the data is preserved on the paired drive. Mirroring provides data protection through redundancy. In addition, mirroring using a 3ware RAID controller provides improved performance because 3ware s TwinStor technology reads from both drives simultaneously. Striping. Striping across disks allows data to be written and accessed on more than one drive, at the same time. Striping combines each drive s capacity into one large volume. Striped disk arrays (RAID 0) achieve highest transfer rates and performance at the expense of fault tolerance. Distributed Parity. Parity works in combination with striping on RAID 5, RAID 6, and RAID 50. Parity information is written to each of the striped 4 3ware Serial ATA RAID Controller User Guide Should a failure occur, the data on the failed drive can be reconstructed from the data on the other drives. Hot Swap. The process of exchanging a drive without having to shut down the system. This is useful when you need to exchange a defective drive in a redundant unit. Array Roaming. The process of removing a unit from a controller and putting it back later, either on the same controller, or a different one, and having it recognized as a unit. The disks may be attached to different ports than they were originally attached to, without harm to the data. For definitions of other terms used throughout the documentation, see the Glossary. Available RAID Configurations RAID is a method of combining several hard drives into one unit. It offers fault tolerance and higher throughput levels than a single hard drive or group of independent hard drives. RAID levels 0, 1, 10 and 5 are the most popular. AMCC's 3ware controllers support RAID 0, 1, 5, 6, 10, 50, JBOD and Single Disk. The information below provides a more in-depth explanation of the different RAID levels. For how to configure RAID units, see Configuring a New Unit on page 91. RAID 0 RAID 0 provides improved performance, but no fault tolerance. Since the data is striped across more than one disk, RAID 0 disk arrays achieve high transfer rates because they can read and write data on more than one drive simultaneously. The stripe size is configurable during unit creation. RAID 0 requires a minimum of two drives. When drives are configured in a striped disk array (see Figure 2), large files are distributed across the multiple disks using RAID 0 techniques. Striped disk arrays give exceptional performance, particularly for data intensive applications such as video editing, computer-aided design and geographical information systems. RAID 0 arrays are not fault tolerant. The loss of any drive results in the loss of all the data in that array, and can even cause a system hang, depending on your operating system. RAID 0 arrays are not recommended for high availability systems unless additional precautions are taken to prevent system hangs and data loss. 5 RAID 1 is also known as a mirrored array. Mirroring is done on pairs of drives. Mirrored disk arrays write the same data to two different drives using RAID 1 algorithms (see Figure 3). This gives your system fault tolerance by preserving the data on one drive if the other drive fails. Fault tolerance is a basic requirement for critical systems like web and database servers. 3ware uses a patented technology, TwinStor, on RAID 1 arrays for improved performance during sequential read operations. With TwinStor technology, read performance is twice the speed of a single drive during sequential read operation. The adaptive algorithms in TwinStor technology boost performance by distinguishing between random and sequential read requests. For the sequential requests generated when accessing large files, both drives are used, with the heads simultaneously reading alternating sections of the file. For the smaller random transactions, the data is read from a single optimal drive head. Figure 3. RAID 1 Configuration Example RAID 5 RAID 5 provides performance, fault tolerance, high capacity, and storage efficiency. It requires a minimum of three drives and combines striping data with parity (exclusive OR) to restore data in case of a drive failure. Performance and efficiency increase as the number of drives in a unit increases. Parity information is distributed across all of the drives in a unit rather than being concentrated on a single disk (see Figure 4). This avoids throughput loss due to contention for the parity drive. 6 3ware Serial ATA RAID Controller User Guide This also means that a RAID 6 unit may be in two different states at the same time. For example, one sub-unit can be degraded, while another may be rebuilding, or one sub-unit may be initializing, while another is verifying. RAID 6 requires a minimum of five drives. Performance and storage efficiency also increase as the number of drives increase. 7 When drives are configured as a striped mirrored array, the disks are configured using both RAID 0 and RAID 1 techniques, thus the name RAID 10 (see Figure 6). A minimum of four drives are required to use this technique. The first two drives are mirrored as a fault tolerant array using RAID 1. The third and fourth drives are mirrored as a second fault tolerant array using RAID 1. The two mirrored arrays are then grouped as a striped RAID 0 array using a two tier structure. Higher data transfer rates are achieved by leveraging TwinStor and striping the arrays. In addition, RAID 10 arrays offer a higher degree of fault tolerance than RAID 1 and RAID 5, since the array can sustain multiple drive failures without data loss. For example, in a twelve-drive RAID 10 array, up to six drives can fail (half of each mirrored pair) and the array will continue to function. Please note that if both halves of a mirrored pair in the RAID 10 array fail, then all of the data will be lost.
