Still going on the reliable 40nm process (a big thumb up for that), Samsung now come with there intesting SSD lines.
- PM953 line, witch is either classic 2.5' SSDs with SATA Express, or M.2 cards with capacitances 480, 960 and 1920GB (M.2 capacity goes to only 480/960GB)
- PM1633 line, witch, thanks to the 12Gbit/s SAS interface aims for the professionals (or mad overclockers?). Samsung say they made up to 160k IOPS for random read, 18k IOPS for random write, sequentional reading 1.1 GB/s and write up to 1.0 GB/s. I would say "cool", but that is just me Capacity range goes from 480 to 3840GB.
- PM1725 line is the best. It comes as either 2.5' SSDs or PCI Express 3.0 cards. Extra large capacty 3200 to 6400GB goes par in par with up to 1 000k IOPS for reading and 120k IOPS for random write. (PCMark 05/Vantage anyone? ) Reading speeds are bumped to 5.5GB/s, writing do 1.8GB/s.
With the 6400GB varians Samsung show longetivity also - 32TB of writting per day for 5 years, witch translate to 5 complete overwrites per day, or about ~58,4PB of written data.
This is impressive at least for combined V-NAND chips. Only we are not informed, of theyare SLC, MLC or TLC… I would hope for MLC, as the Samsung 850 PRO line have... but we see
