Plextor M5M 256GB mSATA SSD
As we mentioned, you don't get any bells and whistles with the Plextor PX-256M5M. I've yet to see an mSATA drive with bells or whistles, so this isn't anything unique to this product.
We've shown mSATA drives before, more than any other review site for that matter. There isn't much to see with the sticker in place.
With the sticker removed, we found a Marvell 88SS9187-BLD2 and a pair of Toshiba 19nm NAND flash chips on this side.
On the other side we found two more Toshiba NAND flash chips and a single Micron 512MB DRAM chip for buffering page table data.
We did find something in our physical inspection of the Plextor M5M that seemed a bit odd. Here we see the Toshiba flash in a BGA (ball grid array) package. This is the first time I've seen a BGA package this far off the PCB.
We didn't run into any issues with the drive and there is little chance the flash will fail, but it's something we haven't seen before.
