Final Thoughts




The ADATA SP550 is a mixed bag. Running it as our OS disk, all three capacity points delivered a good SSD experience. But, as we dig a little deeper and hit the SP550 with extended workloads the shine rubs right off. I suppose that for someone using an SSD for the first time the SP550 will be adequate, after all it's much, much faster than any HDD due to far superior random and sequential read performance.



When comparing the SP550 to the competition, it is, for the most part, faster than the TRION, but that's not much of a compliment. So we need to look at pricing to see if the SP550 is worthy of your consideration. Right now, the SP550 is retailing for $44.99, $72.99 and $134.99 at Newegg. This pricing is low, but it's still too high in our opinion for what the SP550 has to offer.


This is our first look at 16nm Hynix TLC flash, and we aren't coming away impressed. We do like the SMI SM2256 controller, and as we saw from the SMI reference design, the SM2256 controller when paired with decent flash can perform on par with some MLC-based drives except when transferring large chunks of data.


As it stands, we cannot recommend the SP550 when it's only a few dollars cheaper than MLC-based alternatives and the 850 EVO that deliver vastly superior performance.

The Bottom Line: While the SP550 is much faster than an HDD, it does not deliver compelling performance. For the performance you get, we feel the SP550 is overpriced.
