A Drive That Doesn’t Break The Bank

Once again we have a TLC-based SSD in our hands, but this time from Taiwanese memory and storage manufacturer ADATA. With many recognised international awards, ADATA has become one of the world’s leading memory brand, producing various products ranging from RAM to SSDs. So this time round they have sent us their ADATA Premier SP550 with a 240GB capacity for reviewing their first ever TLC-based SSD.

Starting off, the SP550 uses a controller from another Taiwanese company Silicon Motion, which also makes flash controllers for various storage devices such as SD cards, CF cards and USB-based devices. It also comes in a form factor of 2.5-inches and is packed together with a 2mm spacer to slot into laptops that have a 9.5mm-thick drive bay. And the 240GB capacity SP550 has a rated performance of 560MB/s read speed and 510MB/s write speed.

So popping it into our test bench we started running some benchmarks to gauge the performance of the SSD. Using CrystalDiskMark as our benchmark tool, the values we got were quite off from its rated performances but there is disclaimer letting us know that performance might vary. CrystalDiskMark gave us 505MB/s as its read speed and 459.9MB/s for write speed which actually isn’t quite too bad.

However, benchmarks don’t usually tell the entire story so we went ahead and did some real simulation tests, by transferring various files of varying sizes and quantity between drives to get the down low of the actual speeds. Surprisingly the drive had an average of 486MB/s when transferring files which is above the numbers given during benchmarking. One thing that should be mentioned is that the drive still uses AHCI, as opposed to the newer higher performing NVMe protocol.

The SP550 runs and performs quite well in our opinion, and at the offered price range, there aren’t many SSDs that can match this offering. Not to mention the SP550 comes with three-years of warranty and is available in 3 capacities (120GB/240GB/480GB) so choices are aplenty.

CHIP CONCLUDE: The ADATA SP550 features both a decent level of performance and at an attractive price point. If you’re looking for an inexpensive SSD, this is one to consider.
