The specs on states the speed is 3500/3000 MB/s, it could be a mistake, according to the official product web site, the speed should be 3500/2700 MB/s, it is not a big difference and won’t be noticeable for most situations.

It seems two software are included according to the product page, not 100% sure:
1. Acronis True Image, disk migration utility, needs to register the product to get the licences key.
2. ADATA SSD ToolBox, a drive info, diagnostics, system optimization software.

Customer Reviews:
Upgraded my lenovo ideapad 530s’ Samsung PM961 256GB SSD and found a significant jump in terms of already fast SSD performance. My userbenchmark increased fron 86% (aircraft carrier) to 101% (ufo). The crystal disk mark matches the spec (almost) 3459mb/s (read)/ 2457 mb/s (write). This is a SINGLE SIDED board so it would definitely fit the slim laptop. There is only Samsung 970 evo plus that has the single sided from that is priced for 300++ and for 2/3 of the price, this is at par and brings value to your money. | I almost gambled getting the XPG SX8200 PRO or the Sabrent Rocket BUT they are both double sided and it would not cause to bend the board if I force it down. Luckily I stumbled on this ADATA equivalent and I did not had any compatability issue. | Highly recommended product.
