Power Consumption
Low power consumption has always been a staple of Samsung's SSDs, and the EVO is no different. Idle and load power are among the best here. I'm also expanding our DIPM testing, first introduced in the SanDisk Extreme II review:
We're introducing a new part of our power consumption testing with this review: measurement of slumber power with host initiated power management (HIPM) and device initiated power management (DIPM) enabled. It turns out that on Intel desktop platforms, even with HIPM and DIPM enabled, SSDs will never go into their lowest power states. In order to get DIPM working, it seems that you need to be on a mobile chipset platform. I modified an ASUS Zenbook UX32VD to allow me to drive power to the drive bay from an external power supply/power measurement rig. I then made sure HIPM+DIPM were enabled, and measured average power with the drive in an idle state. The results are below:
The EVO is almost as good as the Pro from a slumber power perspective, and significantly better than anything else in the list here.

Agreed: no real drive (read: not a rubbish sale) can touch the price of a 128 GB 840 here in Germany either.MamiyaOtaru - Friday, July 26, 2013 - link
hell with that I want SLCNotmyusualid - Friday, July 26, 2013 - link

why still a dealbreaker? Unless you write a TON. Its a great drive and you dont really need MLC.Heavensrevenge - Thursday, July 25, 2013 - link
The worries of TLC is a pretty useless worry. I still have a 32MB Sony flash stick I used around 2003, and its flash memory wasn't rated and wear-leveled like it does nowadays by design and It's not dead nor corrupted somehow lol. If you have a USB stick older than 5 years old or any flash cards for a camera that's a few years old and still working 100% fine when people weren't so uselessly worried about flash endurance, then these drive will pose no problems whatsoever.Oxford Guy - Thursday, July 25, 2013 - link
I thought the Vertex 2 firmware problems (especially the wake-from-sleep bug) were overblown until I had three of them die. I finally gave up on RMAs because the replacements died, too. Anandtech was so positive about OCZ and its Vertex 2. Funny how the drives didn't turn out to be so great. I don't remember the rave reviews covering the wonderful panic mode, either.HisDivineOrder - Saturday, July 27, 2013 - link
Lots of people were raving about OCZ back then. Today, it's clear. Friends don't let friends OCZ.Shadowmaster625 - Thursday, July 25, 2013 - link
Can you test RAPID by cutting power to a pc while doing normal everyday stuff like surfing the web or watching a youtube or loadign a game. I would like to know how likely it is for windows to have an unrecoverable error if it loses power while this cachign solution is active.Spunjji - Friday, July 26, 2013 - link
I second that request.MrSpadge - Saturday, July 27, 2013 - link
You'd need to be writing to the disk to provoke errors, not reading.
