A test by PC Pro of the 2011-launched Samsung 700Z, which included an 8 GB SSD and a 7200 rpm hard drive, showed a reduction of five seconds in boot time with Windows 7, when ExpressCache was enabled. Another vendor's demo at Computex 2011, involving a laptop also equipped with an 8 GB SSD, showed a boot-time reduction of about ten seconds.
A test by CDRLabs of a stand-alone 32 GB SanDisk ReadyCache product, which was added to a quad-core desktop (Core i5-2400 CPU) equipped with a 7200 rpm hard drive, found a reduction in boot time from 25 down to 14 seconds, but found no significant improvements in random read/write tests. Another similar test of a 32 GB ReadyCache product, conducted by HardOCP, found a reduction in boot time from 52 down to 13 seconds. Yet another test by Expert Reviews found a boot time reduction from 48 down to 35 seconds.
A criticism against ExpressCache in PC Pro was that it "isn't very configurable. You can't, for instance, install an application of your choosing there."Samsung 700Z Chronos review | PC Pro PC World France noted that the ExpressCache software bundled with ReadyCache has a limit of three computers on which it can be activated; their reviewer also expressed dismay at SanDisk's choice of using MLC flash on a caching product.
