How We Screen, System Specs

In gain to our featured flash devices, the Hitachi Deskstar 7K1000.C 1TB 3.5" 7200RPM hard drive has been included for comparison's sake. Other SSDs tested for comparing feature controllers so much as the SandForce SF-2281, JMicron JMF616, Intel PC29AS218A, Marvell 88SS9174, Toshiba TC58NCF618GBT and Samsung S3C29MAX01. Our testing suite consists of four artificial benchmark programs and our own file copying and load time tests.

As you expected cognize, while manufacturers lay claim impressive peak I/O performance out of the box, this performance can belittle ended prison term. Unlike a conventional hard drive, some write mathematical process successful to an SSD is a ii-footstep process: a data block must be erased and then cursive to. Obviously if the drive is new and unused there will be zero to erase and therefore the first step can be bypassed, but this only happens once unless the drive is clipped.

Considering this, we'll test how much operation you can expect to recede from apiece SSD over time. We'll test all drives in their clean inactive state, and so flow the HD Tach full benchmark several times to fill the uncastrated drive. This simulates heavy usage and clearly indicates how performance will be affected after normal long-run use.

Entirely drives in this roundup support the Windows 7 TRIM function, which is meant to counteract these negative personal effects.
