Vortez posted a review on the XPG SX8200 Pro
A quote from the article:
What's new with the SX8200 Pro? Firstly, we get increased speeds, bumping up to 3500MB/s and 3000MB/s, read and write, respectively. The SX8200 was limited to 3200MB/s and 1700MB/s. IOPS are also vastly improved, with 390,000 and 380,000 read and write, representing around a 30% increase on the previous. Speed isn't the only improvement, capacity also gets a little bump, with each tier being stepped up slightly, with the 480GB model now arriving with 512GB, for example.XPG SX8200 Pro Review
