How we test

PC & Tech Authority - - REVIEWS -

For each of the SSDs in this month’s Labs, we used Crys­talDiskMark 5.21 to mea­sure max­i­mum read and write speeds, for both se­quen­tial work­loads and multi-threaded 4K data blocks. You can see these re­sults next to each re­view, and on p80 – along with scores from a 1TB Seagate Bar­racuda me­chan­i­cal drive for com­par­i­son.

While this bench­mark ex­poses each unit’s tech­ni­cal ca­pa­bil­i­ties, it doesn’t nec­es­sar­ily re­flect how dif­fer­ent drives stack up in real-world use. There­fore, we also use the Fu­ture­mark PCMark 8 bench­mark to test how quickly each drive can “play through” a stan­dard set of disk op­er­a­tions, cap­tured from real-world ap­pli­ca­tions in­clud­ing Adobe Cre­ative Cloud and Mi­crosoft Of­fice.

As well as per­for­mance, we con­sider any ad­di­tional fea­tures and func­tions; this might in­clude en­cryp­tion ca­pa­bil­i­ties, ac­ces­sories or soft­ware in the box, and any other good­ies that the man­u­fac­turer of­fers. Fi­nally, we look at the price of each drive, in light of its per­for­mance and fea­tures – plus, of course, its ca­pac­ity. Based on per­for­mance, fea­tures and value for money, each drive re­ceives a star rat­ing out of five.
