Samsung SSD 840 EVO mSATA (120GB, 250GB, 500GB & 1TB) Review
by Kristian Vättö on January 9, 2014 1:35 PM ESTPerformance vs. Transfer Size
ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. The EVO mSATA is top of the class at all transfer sizes. Even though we're dealing with highly compressible data, which is the strength of SandForce, the EVO mSATA turns out to be slightly faster than the Intel SSD 525. Keep in mind that these tests are with an empty drive so TurboWrite plays a massive role and since the test only writes 2GB, all EVO mSATAs perform similarly regardless of the capacity.

Why do people still use mSATA? It might not make a difference for IOPS, but when opening a program the higher sequential read of PCIe would be a benefit. The NAND could supposedly go faster than 540.Kristian Vättö - Wednesday, January 15, 2014 - link
Because the support for PCIe is very limited. There are only a handful of laptops that use PCIe SSDs (and some of the have a proprietary connector like the MacBook Air) and in the desktop world all PCIe SSDs are currently just two or more SATA SSDs in RAID (though that will change during the next few months).bbordwell - Wednesday, January 15, 2014 - link
Any chance we could get an in depth review of Samsung's RAPID now that it is available on both the EVO and the PRO? I am curious if it would have a larger impact for writes on the PRO than the EVO since the PRO does not have the SLC write cache.RShack - Friday, January 17, 2014 - link
What % of your responses are to posters who evidently haven't bothered to even read the dang article?swiftdimension - Friday, January 17, 2014 - link
Just curious, if you guys connect a mSATA drive by letting it dangle connected to power and a SATA cable since the Asrock z68 Pro 3 doesnt have a mSata slot?Kristian Vättö - Saturday, January 18, 2014 - link
We use an mSATA to SATA 6Gbps adapter.Qlaras - Friday, January 17, 2014 - link
So I was considering ordering one of Gigabyte's sole AMD Brix - GB-BXA8-5545, and a 180-240GB mSATA SSD. (Now that the Brix is FINALLY released)Torn between waiting for the Samsung 840 EVO mSATA and just paying the premium for an Intel 525 and getting it now.
The Samsung has newer features/tech, and the price will (probably) be lower - MSRP matches what the 525 is going for now though, and the 525 comes with a 5-year warranty, versus 3 on the EVOs.
Thoughts?

Crucial M500 should be a good compromise -- it's available now and the pricing is competitive.Coup27 - Saturday, January 18, 2014 - link
Did that maximum bus speed vs latency graph really come from Micron? It's clearly been drawn in MS Paint. The Y axis isn't even vertical!Good article nevertheless.

Yup, here's the presentation (slide 9): http://www.flashmemorysummit.com/English/Collatera...
