Mushkin Atlas 480GB SSD Review – Performance Meets Capacity In The Ultra World

Mushkin Atlas 480GB Featured 2Our SSD analysis today is another first for us here at TSSDR as we have finally received a Mushkin Atlas 480GB mSATA SSD, the reigning champion in capacity for mSATA drives at this point and time.

The interest we have seen in this drive, particularly pertaining to it’s height, has been somewhat of a shock as several e-mails have been received asking if we thought it would fit in such and such a laptop or ultrabook.

To answer two of our e-mails, we installed the Atlas 480GB in our Toshiba Z830, and also, a Samsung Series 9, and had no problem with fit whatsoever.  In fact, even we were surprised that there was so little height variation between the two.

The Mushkin Atlas 480GB SSD is a SATA 3 (6Gbps) mSATA solid state drive that is only one third the size of a business card and weighs approximately 10gm.  It’s specifications list it as 50.8mm long, 29.85 mm wide and 5.4mm thick.  We checked ours closely and it is 5mm max.  It is backwards compatible to SATA 2, has full TRIM support and a three year warranty.

The 480GB Atlas contains two printed circuit boards, commonly termed as a mother and daughter board.  One sits atop the other and both are held in place by three connectors. The motherboard contains a LSI SandForce SF-2281 SATA 3 flash storage processor and, in total, there are eight modules of flash memory on both boards.

Micron 25nm 64GB MLC asynchronous NAND flash memory (MT29F512G08CUAAAC5) provides a total of 512GB RAW memory, however, 32GB remains proprietary to LSI SandForce over provisioning and firmware needs.

Once formatted, the Atlas 480GB SSD has a total of 447GB available to the user for storage.  This photograph is an excellent depiction of how the top daughter board folds over and where the three connectors hold it in place.

    OMG,what were they thinking….cheap asynchronous NAND flash memory….yikes

    3 year warranty is a no-go on a $400 plus part.

    still better than TLC flash..
    with 128gbit die flash, this will be in the future possbile without the additional 4 flash chios

    usually I am very pleased with your tests… in this case – well got me a little confused not to compare this drive to sandisk xtreme 480GB (priced at 328,-€ -> 435$), thinking it would best the atlas (this comment should be deemed non existent if you’d mean best msata 480GB drive)

    Mine lasted less than 6 weeks. Completely crashed and can’t do anything with it. I would not recommend this to anyone.

    So it looks like the new crucial 480gb mSata is pretty much the same drive?
