The 840 is a decent drive, though it does use TLC (three bits per cell) NAND instead of the more traditional MLC (2 bits per cell) variety. TLC NAND is slower on writes and has less endurance (~1000 P/E cycles vs. 3000) than MLC NAND, but it's easy to overstate what the impact is. The only thing I'd avoid is the 120GB capacity version - the firmware is stable, but the NAND may only get you to 3 years or so under normal usage until the MWI (media wearout indicator) hits 0. Now, MWI=0 doesn't mean the drive is dead--indeed, there are forums where some models have exceeded the MWI by huge margins and are still functional. It's intended to be a conservative estimate of drive durability.
The 840 Pro is a different drive entirely, using 21nm Samsung MLC NAND. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Steve Tomporowski Sent: Monday, May 6, 2013 3:28 PM To: [email protected] Subject: Re: [H] SSDs and My Documents This is really good to hear, as what I just bought was a Samsung 840....
