KingSpec SATA M.2 NGFF Ultrabook SSD Review (128GB)

Only a few hours before we hit the hustle and bustle of the 2014 Consumer Electronic Show and our friends at KingSpec threw in a loop with the ok to go ahead and post our review on their newest M.2 ultrabook  SSD.  Add to that the fact that I am writing this at 6:30 am and a Northern Canadian snow storm is blowing outside my window and you just have to know that, even after reporting on SSDs for some five years now, it is still one of my favorite pastimes and a passion that still drives me.  Here is a holiday picture I bet you might never expect to see!

Kingspec Christmas Picture

Kingspec is a ‘SSD only’ company based in China and has a staff complement of 1200 employees capable of producing up to 3 million SSDs per month.  KingSpec has been around since 1995 and, although their name is not as popular as many others in North America, they are a global company with products that can be found in popular e-tailer channels.  Most recently, we posted a report on their Multi-Core 1TB PCIe SSD, capable of 2.5GB/s lightning speeds which was a pleasure to review. As for the availability of the KingSpec M.2 SSD we are reviewing today, we might guess that it may be a more client-directed product and only available at retail level, should demand exist.

The KingSpec CHA-M2B7  M.2 NGFF ultrabook SSD is available in capacities of 32, 64 an 128GB and is a 42mm(L) X 22mm(W)X3.2mm(H) SATA M.2 SSD.  To say it is small is an understatement as we can fit four of these on a typical business card with plenty of room to spare.

Kingspec M.2 SSD Size

Performance of the 128GB capacity is listed at 520MB/s read and 300MB/s write with up to 65K IOPS which is actually pretty respectable.  Power specs are listed at 0.3W idle and 1.6W active and the only real negative we hit was that it only has a 2 year warranty; we would like to see 3 minimum.


The KingSpec M2B7 M.2 SSD is based on a JMicron JMF 667H SATA controller that, not only did we test first hand in our KingSpec MultiCore Review, but also, we looked at it in the WD Black2 Dual Drive Review just a few days ago.

Kingspec M.2 SSD Controller

Just below the controller is a Nanya DRAM cache numbered NT5CB128M16HP and two modules of NAND flash memory, one on either side of the PCB.

Also found on the underside of the SSD is a validation sticker that also acts as a security sticker as it cannot be replaced once removed.
