Being only 7mm thick and near one pound, the Crucial M GB is both small and light. All of the models from GB to GB are similar in design, but different in hardware, capacity, and pricing:. One may be wondering why Crucial has decided to use the Marvell 88SS third-generation FPU as Marvell does not necessarily have the best name in terms of performance. Recently however, with the absolutely astounding performance put up by the Plextor M5 Pro series which is the first SSD to use the controller, it will be interesting to see if it can keep the streak going with a slightly different Micron architecture.
Not only does this allow for overprovisioning, but also, allows Crucial to usher higher quality, larger capacity SSDs into the market while keeping them affordable. It will be interesting to see how these M. Revealing the prices, they have certainly done that — affordability for a spacious SSD never before done on this scale! The good news is that larger page sizes increase sequential throughput, but at the expense of latency.
There are some power savings courtesy of ONFI 3. The previous ONFI interface standard 2. The end result is vastly improved performance across the board, the big question being how well does it compare to the rest of the world given how much has changed since the m4 first arrived on the market. There's a lot of data in the table above, but if you look closely you'll see a couple of trends. The obvious ones are increasing page and block size over time.
NAND program latency has also climbed steadily over the years, while endurance decreased. All in all, the picture looks pretty bleak. It's impressive that performance keeps going up each generation given how much the deck is stacked against seeing continued performance improvements. The increase in program time gives you a preview of what we're going to see in the performance pages. Small writes will take longer. Garbage collection routines on a full drive will also take longer to run as each block that needs to be recycled for use has more pages and more data to deal with.
Although Crucial uses a faster controller in the M vs. The M isn't a drive that was built in pursuit of peak performance.
