Re: To RAID or not to RAID, that is the question jesskaat Dec 16, 2009 4:16 PM (in response to Harm Millaard) This is so great! For a laptop, however, I'd recommend an SSD or a hard drive that's designed to withstand falls and other sudden movement. Testing has found that Dynamic Storage Accelerator performance mode, 2 SSD RAID 0 provides up to a 15-percent performance gain as compared to default power management. www.thegeekstuff.com.

There is quite a perfomance gain achieveable, but the drawback is that it requires a hardware controller from Areca. You could do worse, but apart from it being the Rolls-Royce amongst the hardware controllers, it is expensive like the car.Performance wise it will achieve around 85% (X-1) on reads and USB 3.0 offers a cap speed of 5Gbps and is backward compatible with USB 2.0.

Hamming-code parity is calculated across corresponding bits and stored on at least one parity drive.[13] This level is of historical significance only; although it was used on some early machines (for

Triple parity schemes, or triple mirroring, have been suggested as one approach to improve resilience to an additional drive failure during this large rebuild time.[81] Atomicity: including parity inconsistency due to weblink The earlier SATA 1 (largely obsolete) and SATA 2 (available in computers made a few years ago) cap data speeds at 1.5Gbps and 3Gbps, respectively. During early bootup, the RAID is implemented by the firmware and, once the operating system has been more completely loaded, the drivers take over control. Adaptec Whitepaper ^ Gregory Smith (2010).

Thunderbolt also makes RAID possible when you connect multiple single-volume drives of the same capacity. A typical IBM7030 Data Processing System might have been comprised of the following units: [...] IBM353 Disk Storage Unit– similar to IBM1301 Disk File, but much faster. 2,097,152 (2^21) 72-bit words Just about the size of a stick of system memory, an M.2 SSD is much more compact than a regular SSD. navigate here Data is written identically to two drives, thereby producing a "mirrored set" of drives.

Dong Ngo/CNET Performance Storage performance refers to the speed at which data transfers within a device or from one device to another.

And you'll know exactly what's under the hood and how to fix or upgrade your PC, should that become necessary. Software RAID can be implemented as: A layer that abstracts multiple devices, thereby providing a single virtual device (e.g. To fill this gap, inexpensive "RAID controllers" were introduced that do not contain a dedicated RAID controller chip, but simply a standard drive controller chip with proprietary firmware and drivers. Which External Hard Drive To Buy For parity check methods, dedicated controllers offer the possibility of defining a hot-spare disk.

Check out our list of best external drives for more information. Software RAID controllers use the CPU and the RAM on the motherboard. But I have another suggestion for those with very deep pockets. http://puchinet.com/hard-drive/raid-hard-drive.php Pasupathy, J.Schindler. "An analysis of latent sector errors in disk drives".

RAID6 requires a minimum of four disks. Some ultracompact laptops also have an M.2 slot instead of SATA.

Regular RAID1, as provided by Linux software RAID, does not stripe reads, but can perform reads in parallel.[33][34][35] Hadoop has a RAID system that generates a parity file by xor-ing a
