We compare all popular DDR2 and DDR3 speeds on both a fast Core 2 Duo and an older Pentium 4 single core. The big question is a simple one: what memory speed do you really need?

It's not the fastest, sleekest or smallest USB drive, but Corsair's Survivor offers 32 GB of capacity, security features and a waterproof design.

Ethernet-attached Storage Area Networks are the smartest way of handling storage in small and medium-sized businesses. We compare iSCSI SANs from Adaptec and Enhance Technology.

Storage experts typically recommend homogenous RAID arrays, but what happens if you do not use identical hard drives?

We look at a port multiplier for eSATA; a combined portable and permanent storage solution; a USB-to-eSATA dongle and a hard drive cooler and noise dampener. There's something for everyone.

Western Digital's 320 GB Scorpio and Toshiba's MK3252GSX laptop hard drives compete directly against Samsung's Spinpoint M6. Our tests show how the two newcomers compare to Samsung's offering.

Buffalo, Fujitsu, Maxtor, SimpleTech and Western Digital - all offer portable 2.5" hard drives at up to 320 GB, but some still lack features to make backup and synchronization an easy process.

We already compared performance per watt over four generations of Intel CPUs. Now we compare AMD's Sempron, Athlon and Phenom CPUs to see if efficiency has increased over time on the AMD side.

New drives are hitting the market every few weeks; it has become difficult to keep track of them all! We look at three new models intended for high performance and high capacity notebook storage.

We look at how well Phenom scales with increasing clock frequency, by comparing the Athlon 64 X2 and Phenom 9000 using only a single core.

Chaintech, Corsair, Crucial, Kingston and Supertalent battle at the DDR3-1600 and DDR3-1800 summits. Which premium memory product comes out on top?

We added a new interactive charts page that allows you to compare most of Intel's mobile Core 2 Duo processors. The results can also be contrasted to those of our desktop CPU charts.

AMD promised that Phenom could be operated in most socket AM2 motherboards. We tried running the new quad core on ten different products - and failed with most of them.

Though AMD has been unlucky with its Phenom, the new processor represents a major improvement over the Athlon 64 X2. But, just how much better is the Phenom?

Ridata's Solid State Drive offers great robustness while Samsung's doubles capacity to 64 GB. But which one should you buy?

We test AMCC/3Ware, Areca and LSI Logic enterprise-grade RAID controllers for entry-level applications.
