The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
Toshiba has put a strong foot forward into the enterprise SSD storage arena with their 6 Gbb/s MKx001GRZB series of drives that also feature 32nm SLC NAND Flash Memory. These drives are available in capacities of 100 / 200 / 400 GB.
The 6 GB/s interface lets these SSDs achieve sequential speeds of 500MB/s reads and 250MB/s writes. 4K random IOPS are stated as a sustained 90,000 read and 16,400 write.
The speeds this SSD represents is an increase of over 3 times the speed of their highest-performing enterprise HDDs. With power requirement of only 6.5w in operation, these drives give Toshiba an industry-leading 13,800 IOPS/watt power efficiency rating.
Toshiba leverages its leadership as the inventor of NAND flash technology to populate these drives with their latest 32nm enterprise-grade single-level cell (SLC ) NAND flash modules. They are confident in the reliability of the MKx001GRZB to the extent of a 5-year warranty.
With more and more tier-0 storage managers comparing the cost of power requirements of operating a large array of HDDs to the acquisition cost of enterprise-level SSDs such as these are learning that the initial expense can be-well justified. This bodes well for the future of all SSD storage. The MKx001GRZB product page is available here.
I don’t understand why SLC is better than MLC, it has lower sequential/4k writes
It’s very expensive, uses a lot more power
For the most part longevity and performance security…. a bit dated but still valid…
