The Tech Report's attempts to test SSDs to destruction have hit the 500TB mark, with three two-bit MLC NAND drives and one three-bit TLC model all trying to survive. They are using raw SMART data to keep track of sectors reallocated from the spare area to replace flash which has died due to repeated usage. So far the Samsung 840 with its three bit TLC has suffered the most loss of sectors but like the other drives it has not shown much performance degradation. There have been a few other bumps in the road during the tests, check out the full story here.
"Our SSD Endurance Experiment has reached the half-petabyte mark, so it's time for another checkup."

When it comes to hardware testing, PCMark is a widely known and tested benchmarking suite. Developer Futuremark has now deployed PCMark 7 for WIndows 7 alongside PCMark05 for XP and PCMark Vantage for Vista users.
Designed to test a wide range of hardware from low cost notebooks to high performance gaming systems, PCMark utilizes numerous subsystem tests to provide a final composite score for the computer which can then be accurately compared to other users’ scores.
In the same manner as its predecessor PCMark Vantage, PCMark 7 uses traces of actual Windows’ programs to score a system based on actual usage scenarios. For example, the benchmark suite’s storage tests have been designed to allow both home and business users the ability to compare benchmark scores across systems and upgrades (of the same system). Whether using a solid state drive or a mechanical hard drive, PCMark 7 uses recordings of actions in well known Windows applications, including “Microsoft Word, Windows Live Photo Gallery, Windows Live Movie Maker, Windows Media Center, Windows Media Player, Internet Explorer, Windows Defender (Security Essentials) and even World of Warcraft” to replicate how someone would use the computer in a real world situation. The reasoning behind the use of program traces versus pure synthetic testing is the reliability and benefits of real world comparison. Especially when comparing benchmark scores between a base and upgraded system, synthetic benchmarking can show the potential performance increases; however, program traces can more closely showcase the real world performance increases.
With three versions of the benchmarking suite, there is a version to fit various needs and budgets. The Basic Version, Advanced Version ($39.95), and Professional Version ($995.00) offer increased control over the process. Each can be purchased or downloaded from PCMark.com.
"A benchmark is a highly complex and sophisticated piece of software, yet PCMark 7 is easy to use and requires no specialist knowledge or set up," said Jani Joki, Director of PC Products and Services at Futuremark. "Better yet, PCMark 7 Basic Edition is available as a free download so all PC users can benefit from this industrial strength PC test."
Will you be using PCMark 7 in your next benchmarking run?
