The MP34 is rated for sequential read speeds of up to 3,400 MB/s and 2,000 MB/s write; random IO reaches 450K IOPS for read and 400K for writes.
The SSD's price at launch is unknown. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Teamgroup guarantees an endurance rating of 800 TBW, a high value.
