SLC, MLC, TLC, QLC... NAND flash memory technology has gone all the way down, the capacity is getting bigger and bigger, the cost is getting lower and lower, but the performance is getting worse and worse, the life is getting shorter and shorter.
Recently, Micron released the world's first QLC flash SSD, the ION 5210. The programming/erasing cycle is only poor for 1,000 times. It can only tolerate around 0.5 writes per day. Officials also admit that it is basically suitable for reading intensive applications. .
At this time, if you look at the Optane Optimus of the Intel 3DX Point flash technology, it suddenly feels like an underground, a heaven.
Recently, Intel quietly launched the Optimus SSD 905P series, which was a small upgrade of the previous Optix SSD 900P. The capacity has been expanded, and the performance and lifespan metrics are still a mess.
Ao Tang SSD 905P offers two kinds of specifications One is PCI-E expansion card style, capacity is 960GB, and the other is U.2 2.5-inch disk specification , Capacity 480GB, the latter is also taking PCI-E 3.0 x4 high-speed channel, performance is not a problem at all.
Now many high-end Intel motherboards have begun to be equipped with U.2 interfaces, which can avoid the limited bandwidth of SATA interfaces, the limited size of M.2 interfaces, and the limited expansion of PCI-E interfaces.
Continuous read and write speed 2.6GB/s, 2.2GB/s , traditional NAND PCI-E SSD can also be easily done, but Random read and write speeds up to 575,000 IOPS, 550,000 IOPS, you can throw off a few streets, and read and write delay is only 10 microseconds.
The life span is equally terrible. The lifetime data writes of the two are 17.52PB (17520TB), 8.76PB (8760TB), and the warranty period is five years. It can be written as 9.6TB per day and 4.8TB per day. This is equivalent to writing every day. Into 10 times.
In contrast, Samsung's latest flagship 970 PRO 512GB has a lifespan of only 600TB, which is almost 15 times faster than it is!
Ao Tang 905P 480GB, 960GB official suggested retail price is $599, $1299 A 480GB U.2 version has appeared on the Akihabara market in Japan, and the price is 77414-79800 yen. About RMB 4,600 yuan up and down - This is almost the only 'weakness'.
It should also have the M.2 version. ASRock has leaked it before, but it is not clear when it will be released.
