Pros:

Small, read speed, write speed, price
Cheap! The 240GB model is the sweet spot for the SP550 series but all of the drives break new ground for retail SSDs.
Solid read speeds, ADATA has their own SSD Toolbox software, Free copy of Acronis True Image HD, 7mm to 9.5mm adapter included, Price

Cons:

Sustained write performance is a problem with most TLC drives and the SP550 just can't shake the TLC blues.
Some of the slowest sustained write speeds we've seen on an SSD

Some of the slowest sustained write speeds we've seen on an SSD

Expert reviews and ratings

ADATA Premier SP550 240GB is the second TLC drive (after OCZ Trion 100 240GB) that I've tested and it made a very good impression. The performance is strong, exactly as the manufacturer claims while the price is simply killer. It is the cheapest 240GB...

ADATA on the other hand seems to not have that figured out yet. While the read scores for the drive were very respectable the sustained write scores were not at all, diving down to around 100 MB/s. This was very apparent in our AIDA64 linear write test....

The SP550 is Adata's latest contender in the entry level market. While read performance is very good, write performance suffers with multi-GB transfers, but it is priced fairly cheap to make up for it. So, if you are looking for a cheap SSD to speed up...

As currently one of the cheapest budget solid-state drives on the market the ADATA Premier SP550 480G delivers surprisingly solid performance. Faced against older flagship drives and even some faster M.2 model SSDs the SP550 acquitted itself well, often...

We've collected all the data we need, so it's time to see where the SP550 falls in our rankings. We distill the overall performance rating using an older SATA SSD as a baseline. To compare each drive, we then take the geometric mean of a basket of...

The ADATA SP550 SSD Series are some of the lowest priced drives that you can buy and that will likely get peoples attention. We fully understand that as a 240GB SSD for under $55 without the hassle of rebates is pretty amazing. If you've never tried an...
