JMicron JMF667H Reference Design (128GB & 256GB) Review

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.
Wow, this is something I didn't expect. With Toshiba NAND, the JMF667H can in fact challenge Samsung's 840 Pro and beats several other SSDs. With IMFT NAND the performance is a bit worse but it's still average and about similar to what Samsung's 840 EVO offers.

They should support TLC aswell.Couple TLC flash with a cheap and decent controller and you have a cheap and still reasonably performing drive.
I'm really surprised how far jmicron came over the last few years.

Is anyone but Samsung getting SSD grade TLC at this time though?Laststop311 - Thursday, May 29, 2014 - link
Samsung has that unique position they can integrate the design of all the different parts of an ssd all under Samsung. The controller, dram, nand, firmware. This allowed samsung to quickly transition to TLC nand. This really makes the 1TB evo drive the best 2.5" drive for value/performance ratio. Samsung has the best performing m2 drive too the xp941.hojnikb - Thursday, May 29, 2014 - link

Yes. I have Corsair's Force LX and ADATA's SP620 but they'll have to until I come back from Computex.hojnikb - Thursday, May 29, 2014 - link

Can we also see a review for the Samsung XS1715 and the SMART Optimus Ultra SSDs?vonWolfhausen - Thursday, May 29, 2014 - link
Agreed. I have a PNY optima 240gb that I picked up for $90 (the discount actually came through). The SMI controller in it is legit. 500read/300write with low power consumption (micron 20nm sync MLC). Im curious about the performance consistancy, seems ok
