RAM Put to the Test: ECC vs Non ECC Memory Performance

Much of the ECC versus Non-ECC argument comes down to speed versus reliability. The reliability argument at least is easy to validate, but to settle the question of whether ECC actually lowers system performance, we ran a series of benchmarks with standard RAM, ECC RAM, and Registered ECC RAM that all run at the exact same frequency, timings, and voltage.

Understanding SSDs: Why SSDs hate write amplification

I often tell people that SSDs work better with more free space, so anything that increases free space will keep WA lower. The two key ways to expand free space (thereby decreasing WA) are to 1) increase over provisioning and 2) keep more storage space free (if you have TRIM support).

Samsung 840 Pro SSD Review: Topping Performance and Reliability

While the Samsung 830 Series and many of its year-old peers may still be attractive, Samsung is ready to move on to bigger and better things. Their new flagship offering, the SSD 840 Pro, is said to refine the 830 Series' firmware with faster random and sustained performance as well as improved reliability.

Since most SSD competitors use the same rehashed components, Samsung has been in a unique position to shake things up over the last few years, and it's done a fine job. We had nearly no expectations for 2010's 470 Series, but we were pleasantly surprised when it dominated our performance charts. Last year's 830 Series gave a repeat performance, so we can only hope the same of the 840 Pro.

WOF: Do you carry a USB drive every day? If so, what's on it?

With flash storage being more affordable, compact and rugged than ever, it seems common for people to routinely carry a USB drive -- or six, in the case of our news editor Rick, who runs a PC repair business. Naturally, most of his drives contain bootable utilities, operating system installers...
