Silicon Motion has practically become the new SandForce. Almost every tier three manufacturer (i.e. one with no controller/firmware IP or NAND fab) has released an SM2246EN based drive in the past ten months and recently Silicon Motion scored two major tier one partners (namely Micron/Crucial and SanDisk) as well. To be honest, this hasn't come as a surprise because the SM2246EN is a really solid controller with good performance and more importantly it's been mostly issue free (which is something that cannot be said about SandForce). 

Mushkin's Reactor combines the SM2246EN with Micron's latest 128Gbit 16nm MLC NAND, and this is actually the first time I've encountered a non-Micron/Crucial SSD with Micron's 16nm NAND. That really emphasizes the benefit NAND manufacturers have because Micron has been using 16nm NAND in its own SSDs for over six months now, but the company hasn't begun shipping it to others in volume until now. I suspect the volumes are still fairly low because the Reactor only comes in 1TB capacity, which is still fairly expensive and thus limits the demand to a level that is easier to manage compared to the more popular 256GB and 512GB models. I was told that 256GB and 512GB models may follow later, but as of now Mushkin will only be offering the Reactor in 1TB.

Mushkin Reactor Specifications
Capacity 1TB
Controller Silicon Motion SM2246EN
NAND Micron 128Gbit 16nm MLC
Sequential Read 560MB/s
Sequential Write 460MB/s
4KB Random Read 74K IOPS
4KB Random Write 76K IOPS
Encryption N/A
Endurance 144TB
Warranty Three years

In terms of features the Reactor is a fairly typical value drive without any special features. Neither hardware accelerated encryption nor DevSleep is supported, although the Reactor does support slumber power states for low idle power consumption. Endurance is a respectable 144TB, which translates to 131GB of writes per day for three years.

Moreover, the retail package doesn't include anything in addition to the drive itself and Mushkin offers no software/toolbox for its SSDs.


There are sixteen NAND packages on the PCB with eight on each side. Since we are dealing with a 128Gbit (16GB) die, that translates to four dies per package. Mushkin actually does the packaging in-house (i.e. buys NAND in wafers and then does the binning and packaging), which is why the packages lack the typical Micron logo and labels.

Test Systems

For AnandTech Storage Benches, performance consistency, random and sequential performance, performance vs. transfer size, and load power consumption we use the following system:

CPU Intel Core i5-2500K running at 3.3GHz (Turbo & EIST enabled)
Motherboard ASRock Z68 Pro3
Chipset Intel Z68
Chipset Drivers Intel + Intel RST 10.2
Memory G.Skill RipjawsX DDR3-1600 4 x 8GB (9-9-9-24)
Video Card Palit GeForce GTX 770 JetStream 2GB GDDR5 (1150MHz core clock; 3505MHz GDDR5 effective)
Video Drivers NVIDIA GeForce 332.21 WHQL
Desktop Resolution 1920 x 1080
OS Windows 7 x64

Thanks to G.Skill for the RipjawsX 32GB DDR3 DRAM kit

For slumber power testing we used a different system:

CPU Intel Core i7-4770K running at 3.3GHz (Turbo & EIST enabled, C-states disabled)
Motherboard ASUS Z87 Deluxe (BIOS 1707)
Chipset Intel Z87
Chipset Drivers Intel + Intel RST 12.9
Memory Corsair Vengeance DDR3-1866 2x8GB (9-10-9-27 2T)
Graphics Intel HD Graphics 4600

    I just checked, my Vertex 4, 256 GB, has 72 TB of Writes from host (Raw value 36277402795) after a little more than 2 years (18461 hours) of use. I kind of expect it to die around the 350 TB mark, so I'm not that concerned. But with this drive I would be. I guess it's based on personal use.

    It is still Feb 9, 2015, and the price comparision chart shows this new Mushkin and a Samsung 850 EVO both at $390. Mushkin used to be a great memory OEM, but you don't hear much from them anymore. If the Mushkin was $60 cheaper, I would definately buy it. But with the two both at the same price, I would go with Samsung again. Never lost a bit, and it comes with the Samsung Magician toolbox.

    They still make memory. The problem is that there's much less justification to buy premium RAM nowadays.
  • KAlmquist - Saturday, February 14, 2015 - link

    The prices are only the same if you buy from Amazon. Newegg prices (including shipping) are $361 for the Mushkin drive and $404 for the Samsung 850 EVO.

    Speaking of SSD reviews, now I want to see this one!

    Crucial MX200 1TB SATA 2.5 Inch Internal Solid State Drive - CT1000MX200SSD1
    Sequential reads/writes up to 555 / 500 MB/s on all file types
    Random reads/writes up to 100k / 87k IOPS on all file types Up to 5x more endurance and over 2x more energy efficient than a typical client SSD
    **Dynamic Write Acceleration delivers faster saves and file transfers** (might help in destroyer benchmark)
    Includes spacer for 9.5mm applications

    Just released on Amazon.

    I will be getting my MX200 samples this week, so the review will come in the next few weeks.
  • rahuldesai1987 - Monday, February 9, 2015 - link

    Great! Keep coming up with the reviews.

    I just ordered this one to put in my 2011 MacBook Pro optical drive bay, alongside an M550 boot drive. Any reason I might want to switch them and put the Mushkin drive as the main boot drive? I'm going to move my iTunes library and video editing scratch disk to the secondary drive and thought the power saving features of the Mushkin would make sense for a secondary drive that's not accessed as often, and the M550 looks like it has higher IOPS and slightly faster sequential read, but slower sequential write (so, a wash there?). Is there a clear choice here for a primary and secondary drive? (and yes the optibay is sata3 - I believe some models that year were still sata2)

    The only drive in the same price range is the Crucial M500 960GB for $300, and it wasn't included in the comparisson?!!?
