Samsung SSD XP941 Review: The PCIe Era Is Here
by Kristian Vättö on May 15, 2014 12:00 PM ESTAnandTech Storage Bench 2011
Back in 2011 (which seems like so long ago now!), we introduced our AnandTech Storage Bench, a suite of benchmarks that took traces of real OS/application usage and played them back in a repeatable manner. The MOASB, officially called AnandTech Storage Bench 2011 - Heavy Workload, mainly focuses on peak IO performance and basic garbage collection routines. There is a lot of downloading and application installing that happens during the course of this test. Our thinking was that it's during application installs, file copies, downloading and multitasking with all of this that you can really notice performance differences between drives. The full description of the Heavy test can be found here, while the Light workload details are here.
The same goes for our 2011 Storage Bench: the XP941 is unbeatable. Only in the Light Workload test, the 8-controller OCZ behemoth is able to beat the XP941 by a small margin, but other than that there's nothing that can challenge the XP941. The consumer-oriented OCZ RevoDrive comes close but the XP941 once again shows how a good single controller design can beat any RAID 0 configuration.

rod, if you go ,as well as Everspin, look out for Crocus Technology Russian MRAM HW makers ARM licenced their IP , and Avalanche Technology tooRamCity - Monday, May 19, 2014 - link
Yes, I will be going to Computech. I'll add those vendors to my visit list and check out what they are up to if they have a booth.RamCity - Monday, May 19, 2014 - link
I mean Computex!Jay77 - Thursday, May 15, 2014 - link
I suppose I should read more than the first and last pages if I'm going to make comments.Babar Javied - Thursday, May 15, 2014 - link
There is a mistake/typo in "Performance Consistency & Trim Validation" under the "Trim Validation" section. Below the first graph in the said section, you have wrote "doesn't treat PCIe drives the same even if the utilize the same AHCI" when you ment to say "even if THEY utilize the same AHCI"Ryan Smith - Thursday, May 15, 2014 - link
Fixed. Thank you for pointing that out.BMNify - Thursday, May 15, 2014 - link
so basically you gimped the one and only raid 0 test by not doing it in windows or even better simply boot any linux iso/usb stick and formatted the ssd-xp941 WITH the samsung "F2FS" file system for maximum speed as that is written especially for ssdKristian Vättö - Saturday, May 17, 2014 - link
I did RAID the XP941s in Windows as well but the results were similar so I figured that there is no need to report the results separately.rocky12345 - Thursday, May 15, 2014 - link
I like that there are extra speed speed in these new devices but it seems everyone is so stuck on more speed more speed..lol I am sorry but when a standard SSD can boot a windows 7 in about 6 seconds when are people going to be happy. My Asus laptop has a SSD in it & boots in about 6 to 7 seconds & things like firefox open even before my finger un-clicks the mouse button to open firefox. now everyone is saying standard SSD is to slow..lol to funny. What I would rather like to see is bigger SSD drives at a better price. We already have good speed but the big drives still cost to much for most people when they can make a 1TB SSD at about the same or just slightly more than a standard hard drive then maybe they should be more worried about all these new extreme speed drives but if they make standard SSD drives go the way of the doo doo bird then we are never going to see low priced SSD anything because they will always be treating anything SSD related as new tech just a thought.BMNify - Thursday, May 15, 2014 - link
"but it seems everyone is so stuck on more speed more speed..lol I am sorry but when a standard SSD can boot a windows 7 in about 6 seconds when are people going to be happy..."well obviously speed is not for you, but how do you expect current non volatile ram to lower in price if they don't bring out newer kit to replace it at today's higher price points !
im not sure you understand the driving forces here as regards people wish for faster data access, we really need/WANT a so called "universal non volatile ram [such as those Everspin ST-MRAM DDR3 DIMMs referenced ]" sooner than later at equivalent ddr3 2400,wideIO2,HMC speeds and configurations so we can start to take better advantage of the higher data throughput and data manipulation these bring to the table, its not good enough to x264 encode UHD content in real time right now, then and only then will we start to consider we are starting to get close to enough general speeds, ALIMO....
