If you aren't familiar with just how cute the M.2 form factor is, the picture below shows it attached just below a SATA power and data connector which, when you include the plugs, is significantly larger than the 128GB M.2 SSD. This allows you to slip this style of SSD into just about any sized device you could want as long as you have an M.2 connector. The KingSpec models that The SSD Review just benchmarked use a JMicron so aren't the fastest on the block but that has nothing to do with the size as these top out at SATA 6Gbps just like any other drive. Check their full reivew here.
"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 recently started shipping a new PCI-E based SSD that achieves more than 2.5GB/s sequential read performance from multiple mSATA SSDs behind a 6Gbps LSI RAID controller. The KingSpec MC2J677M1T is a full height expansion card with a PCI-E 2.0 x8 interface.
The new KingSpec solid state drive is bootable and uses a 6Gbps LSI RAID controller that connects to eight 6Gbps mSATA slots. The drive comes in 1TB and 2TB total capacities and the eight 6Gbps mSATA slots are occupied by eight 128GB or 256GB mSATA SSDs. Each mSATA SSD is powered by a Jmircon SSD controller, NANYA-manufactured DRAM cache, and Intel MLC NAND flash. Further, the LSI RAID controller is actively cooled by a small fan.
As far as performance goes, the 1TB model is rated at 84,000 IOPS and approximately 2GB/s sequential read and write transfer speeds. The SSD Review received a sample of the new drive and provided some preliminary benchmark results in the form of an ATTO benchmark run. At a queue depth of 4, the KingSpec MC2J677M1T achieved 4K reads of 2567 MB/s and 4K writes of 1613 MB/s.
The 1TB KingSpec PCI-E SSD will be available later this year for between $2,000 and $3,000 USD.
When asked for his thoughts, PC Perspective storage editor Allyn Malventano noted that the eight JMicron-driven mSATA SSDs in RAID is just asking for trouble, and the 4K random IO offered by the drive is actually less than some single drive SATA SSDs on the market. Unfortunately, the LSI RAID controller is “a major bottleneck for SSD-level random access.”
