TDK is evidently stoked about its SDG3B solid state drive line, so much that it's announcing the launch of these industrial SSDs a month before release. Dubbed SDG3B, these SATA 3Gbps SSDs come equipped with TDK's GBDriver RS3 controller ICs. The focus here is on data reliability instead of balls-to-the-wall performance, and underscoring that point is the complete absence of cache.
Even without any cache, TDK says the SDG3B line supports an effective read speed of 160MB/s. Write speeds are even more pedestrian, with versions using single-level cell (SLC) NAND flash memory rated at up to 60MB/s, and multi-level cell (MLC) NAND flash memory-based drives just 25MB/s.
What the SDG3B drives lack in performance, they make up for in other areas, such as auto-recovery functions, a power interruption tolerance algorithm, ECC function scalable to 44-bit/sector, an auto refresh function to defend against power supply problems, an advanced static wear leveling function and data randomizer (both developed by TDK), SMART support, and 128-bit AES encryption.
These drives are intended for industrial equipment and embedded devices, such as thin client PCs, tablets, automotive applications, office equipment, karaoke machines, and so forth.

I heared that when you put ssd's in RAID you loose trim function. Is that true? Anyone know? I looked it up but there seems to be a lot of confusion out there.
