Top Solid State Disks and TB Drives Reviewed

Lucas123 writes "Computerworld has reviewed six of the latest hard disk drives, including 32GB and 64GB solid state disks, a low-energy consumption 'green' drive and several terabyte-size drives. With the exception of capacity, the solid state disk drives appear to beat spinning disk in every category, from CPU utilization, energy consumption and read/writes. The Samsung SSD drive was the most impressive, with a read speed of 100MB/sec and write speed of 80 MB/sec, compared to an average 59MB/sec and 60MB/sec read/write speed for a traditional hard drive."

Re:Longevity of NAND flash

Will this ever die? The write cycle counts in modern flash is in the millions now. Doing the math you very easily get 20+ years before write cycle wear is a concern: http://www.storagesearch.com/ssdmyths-endurance.html

How many heavily used spinning drives do you know that last even 10+ years?

You obviously wouldn't be overwriting any data already stored on the drive

No, but the wear-leveling routines in the drive will happily move around your existing data so that rarely written sectors are available for heavy writing operations.

Seriously, this "issue" comes up in every discussion about SSDs, and it seems like people are just unwilling or unable to accept that what was once a huge problem with the technology is now not even remotely an issue. Any SSD you buy today should outlive a spinning disk, regardless of the operating conditions or use pattern. It is no longer 1989, engineers have solved these problems.
