How We Test, System Specs

Along with an array of newsbreak drives, we've included the Western Digital 4TB 3.5" 7200RPM and Horse opera Digital Velociraptor 1TB 10,000RPM hard drives for equivalence's interest. Other SSDs tested have controllers such as the SandForce SF-2281, JMicron JMF616, Intel PC29AS218A, Marvell 88SS9174, Toshiba TC58NCF618GBT and Samsung S3C29MAX01. Our testing suite consists of iv synthetic benchmark programs and our ain lodge copying and load time tests.

As you likely know, while manufacturers claim impressive blossom I/O performance out of the box, this performance can diminish over time. Dissimilar a conventional hard drive, any compose mathematical operation made to an SSD is a ii-step litigate: a data block essential atomic number 4 erased and then written to. Obviously if the drive is new and unused there will be cypher to wipe off and therefore the first step can be bypassed, but this only happens once unless the get is trimmed.

Considering this, we'll examination how much performance you keister expect to mislay from each SSD over clip. We'll examine all drives in their clean unused state, and then run the HD Tach full benchmark various times to fill the entire thrust. This simulates heavy usage and clearly indicates how performance will be affected later normal long-life-term use.

Every last drives in this roundup support the Windows 7 TRIM subroutine, which is meant to countercheck these negative effects.
