As an experiment, I bought one of these for use as a SLOG. It was cheap:
Intel 320 Series 40 GB Internal 2 5" SSDSA2CT040G310 SSD Solid State Drive 735858219754 | eBay
From the description, the seller says "It like new we just pull out and up grade bigger drive, any questions ask."
Seems to good to be true and probably was. Once in hand, I retrieved the smart data and find the disk has been powered on for about 2 years, 24x7. Oddly, the media wear looks like new and the total writes are low (about 120GB total). It's as though the disk was installed in a machine and never used much.
Would you all consider a powered-on for two years 24x7 a "new" disk? Am I interpreting the smart data correctly?
