The 512GB Crucial M4 is regarded as the highest-capacity solid-state forces we’ve tested; it moreover proven to be among the quicker visitors. Using a Marvell 9174 controller, 25nm MLC (multi-level cell) NAND flash memory, as well as the newest SATA 6Gbps interface, the M4 read the 10GB assortment of little files plus folders at 416.7 megabytes per next (MBps). The drive was equally fast whenever reading a single big file—it utilized the 10GB test file at 472.8 MBps.
The M4 proven to be much slower at composing files, however; it wrote the 10GB file/folder combo at a poky 265.1 MBps, plus it wrote the single 10GB file at a leisurely 326.8 MBps. Because SSDs have a limited write life, many persons usually tend to utilize an SSD to shop the computer’s working program plus application software than to shop quickly changing information (documents, images, music, plus additional kinds of files). So it can be argued which the M4’s great read performance renders this SSD a sturdy value all about its own.
This is a big ability drive, yet, plus when flash memory has dropped inside cost considerably over the previous year, it’ll nevertheless expense we. Crucial lists the M4 at $ 425 for a bare drive. (A package which involves a mounting bracket along with a SATA cable adds $ 5 to the cost tag, whilst a kit with adata-transfer software adds $ 12, thus always learn that 1 you’re obtaining.) We found the kit which involves the data-transfer software (yet no SATA cable) marketing online for $ 400 (because of January 22, 2013). That’s a amount of change, nevertheless whenever we break it right down to expense per gigabyte, we end up with a extremely reasonable—for an SSD, anyway—78 cents per gigabyte. A smaller-capacity high-performance drive, like the 256GB Samsung 840 Pro (with a $ 239 street price), fees closer to 94 cents per gigabyte. Samsung’s 512GB 840 Pro, meanwhile, fetches a street cost closer to $ 490.
So the M4 scores big wins inside 2 categories—price plus read speed. Knowing which an SSD may inevitably wear out, but, customers could furthermore take the manufacturer’s guarantee into account. Corsair provides a three-year guarantee where other manufacturers—including Samsung—provide five years of coverage. Overall, Crucial’s 512GB M4 is a wise deal.
