Meet the SanDisk Extreme PRO SSD series
SanDisk has released the Extreme Pro series SSD which we'll benchmark and review. Though performance wise they will only be a notch faster, they offer better endurance, ling lasting performance, 10 years warranty and slightly better pricing as well. Meet the “cream of the crop” from SanDisk as we review their all new Extreme PRO SSDs with nCache technology. The successor to their magnificent Extreme II series SSD are made in-house by SanDisk themselves including the PCB design and the actual NAND storage flash memory. The SSD series has been developed alongside a Marvel controller tied to SanDisk NAND flash memory.
With the Extreme Pro series Sandisk ups their most popular SSD series a notch. It is a bit faster, but more importantly, SanDisk focused a lot on long-lasting performance. Typically over time performance of an SSD degrades quite a bit. That's different with the Extreme Pro series. There are more advantages, not only endurance, but lifespan has increased as well. Sandisk guarantees 80 TB written. So with 10 years lifespan even if you write 20 Gigabyte of data per day 365 Days a year that should be peanuts. In fact they are so confident about it that they will guarantee this with a 10 year limited warranty. While stability and safety of your data have become a number priority for the manufacturers, the technology keeps advancing in a fast pace as it does, the performance numbers a good SSD offers these days are simply breathtaking. 450 to 500 MB/sec on SATA3 is the norm for a single controller based SSD. Next to that, in the past year NAND flash memory (the storage memory used inside an SSD) has become much cheaper as well. Prices now roughly settle at just under 1 USD per GB for the end-user. As such, SSD technology and NAND storage have gone mainstream. The market is huge, fierce and competitive, but it brought us where we are today offering nice volume SSDs at way more acceptable prices.
SanDisk pairs the SSD series with a Marvell Monet (88SS9187-BLD2) controller, they combine it with their own and latest 19nm NAND flash memory. The end result is a SSD series that is offering incredible specs, these devices passes 500 MB/s in both read and writes (depending on the volume size of the SSD). Now I state this in all my SSD reviews; not one test system in my lab has a HDD, everything runs on SSD while I receive and retrieve my bigger chunks of data from a NAS server here in the office. The benefits are performance, speed, low power consumption and no noise. Today's product passed crazy read speeds of 550 MB/sec with measured write speeds of 520 MB/sec (for the 240GB version). When you think about that performance and place it in relation to real-world performance (if the source is equally fast), that means you could copy the entire contents of a CDROM in just over a second to the SSD and a DVD in less than 10 seconds.
SanDisk launched this new Extreme Pro SKUs with a Marvell Monet (88SS9187-BLD2) controller tied to high performance 19nm SanDisk Synchronous NAND. Sandisk submitted the 480 GB model with seriously impressive specs as these models have advertised sustained read/write levels of 550 MB/sec and 520 MB/sec respectively. SanDisk Extreme PRO SSDs supports TRIM and S.M.A.R.T. features and has a mean time between failures (MTBF2) of 2,000,000 hours, making the drives highly reliable to secure valuable personal data, essential for today’s mobile computing applications.
Three SKUs will be released by them:
- 240 GB SDSSDXPS-240G-G25
- 480 GB SDSSDXPS-480G-G25
- 960 GB SDSSDXPS-960G-G25
With 4K random write performance estimated at roughly 90.000 IOPS (input/output operations per second) it is here to make a sturdy impression alright. Have a peek, after which we'll dive into the technology behind it and obviously we'll present you a nice performance overview.
