SSD of the Week – Adata Premier SP550

It has been a while since our last SSD of the Week post, but after seeing the current prices of the Adata Premier SP550, we just had to bring it back. The Adata Premier SP550 is an entry-level SSD designed to meet the needs of those who want to upgrade to flash storage, but need to pinch pennies at the same time. With this in mind Adata took Silicon Motion’s SM2256 controller and paired it with SK Hynix’s TLC to deliver a very price competitive product. Right now the 480GB model is only $114.99! That is just under $0.24 per GB!

    Hi, I am looking for a budget ssd for an older laptop and the SP550 looks like a very attractive choice, but at this price there is also the Integral P Series 4 with MLC and an unspecified Phison controller. Unfortunately I cannot find any reviews for the Integral drive, does anyone have any experience with this UK based firm? I am looking at the 240 gb models. Thanks
