Introduction

I’ve had the pleasure to review several new drives with triple-level-cell (TLC) NAND recently and today it is time to take a closer look at ADATA’s Premier SP550 solid state drive. The drive is equipped with said TLC flash and an SMI controller to provide an affordable performance upgrade. The ADATA Premier SP550 is available in capacities from 120GB and all the way up to 960GB, I’m however taking a closer look at the 256GB model today.

Let us start with the basics. The ADATA Premier SP550 is a 2.5-inch solid state drive with a 7mm height that makes it a perfect fit for ultrabooks. ADATA also packed a drive spacer along for notebooks that require a 9.5mm drive. This makes it suitable for almost any system, mobile or stationary.

As previously mentioned, the SP550 utilities TLC flash and an SMI2256 controller that comes with all the features that you want and a couple more. The drive naturally supports the basics such as NCQ, SMART, TRIM and Garbage collection, but it also features a low-density parity check error correction code (LDPC ECC) and RAID engine. The drive also supports SLC Caching and comes with a DDR3 DRAM cache buffer for sustained transfer speeds. All that along with Data Shaping technology should ensure data integrity and stability.

The endurance is rated for 90TB total bytes written (TBW) and the SP550 has a mean time before failure rating of 1.5 million hours. The 240GB model is rated for a sequential read performance up to 560MB/s and a sequential write performance up to 510MB/s. That is pretty good for a small drive that’s TLC based. The random performance is rated for 75K IOPS on both read and write operations. Part of the good performance rating comes from the intelligent SLC caching algorithm of the drive that allows NAND flash memory to operate in SLC mode and boosts SSD read and write performance.

A feature not mentioned above is the DevSleep, or Device Sleep, that in supported systems will send the drive to an even deeper sleep state where it consumes close to zero amount of power. Instead of keeping a data channel open for a wake-up signal, the DevSleep uses a power signal to wake the drive back up.

ADATA also got an SSD toolbox that makes maintenance of the drive an easy thing. You can quickly and conveniently configure, optimize, and monitor SSDs, from overall status to specific drive health and lifespan info. Speaking of lifespan, the ADATA Premier SP550 is backed by a 3-year warranty.

Inside the two-piece encasing, we find a 2/3 sized PCB where we see that nothing but quality components were used. The NAND is rom SKhynix, the cache from NANYA, and the controller from Silicon Motion.

    So far, I’ve been using the Adata Premier SP550 SSD (240GB) for about 4 months (since Mar-2016),
    and things are good: My laptop bootup speed is up by about 3 times, to under 30 seconds! Worth the upgrade from HDD to SSD!

    Only thing was the need to use a disk imaging software to copy the laptop OS & setup from the old HDD to the new SSD.
