Performance vs. Transfer Size
ATTO is a useful tool for quickly measuring the impact of transfer size on performance. You can get the complete data set in Bench.
I pointed this out in the 4KB random write section, but Samsung continues to do a great job of dealing with low queue depth transfers on the EVO. Performance is consistently great across all of the EVO capacity points. There's also no difference between the EVO's behavior here and the 840 Pro.

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

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.
