Then I tried an internal transfer by copying and pasting the movie from the desktop to the hard drive, which took eight seconds.Īll in all, very respectable data transfer times.įinally, I tested the SSD for boot times. Next, I downloaded the same movie to a USB 3.0 flash drive. The movie took 1 minute and 41 seconds to upload. USB 3.0 has data transfer rates of up to 4.8Gbps. I then transferred a 1.81GB MP4 movie ( Star Wars) from a USB 3.0 drive to the hard drive. The SSD's sequential read/write speeds ranged from 406MBps and 325MBps, respectively, on the low end to 509MBps and 488MBps on the higher end.Īs is typical, the SSD's performance in tests fell below what Samsung's specification sheet claimed, which is 540MBps read speeds and 520MBps write speeds. In fact, I've never seen a drive with such a wide variance in read/write times, but all were very good. I found the Blackmagic performance benchmark tests on the 840 EVO a bit all over the place. I used Blackmagic Disk Speed Test benchmarking software for Macs to test the performance of the SSD. It also has USB 3.0 5Gbps external ports. The computer has a SATA 3.0, 6Gbps internal drive interface. Performance benchmark testsįor the benchmark tests, I used an Apple MacBook Pro running OS X Mountain Lion (v10.8.4) with 8GB of RAM and a 2.5GHz Intel Core i5 processor. Those savings, traditionally, are passed on to the consumer and make SSDs more marketable to the general public. The greatest advantage to TLC NAND flash is that it increases flash density by roughly 33% and therefore reduces the cost to produce the flash.
