Samsung gives the SSD 990 Evo Plus much faster storage
The SSD 990 Evo gets a Plus successor. Samsung skips a memory generation and uses fast V8 chips.

Just nine months after the launch of the SSD 990 Evo, the SSD 990 Evo Plus follows. Technically, both models are very similar, but Samsung now uses newer NAND flash memory with higher transfer speeds.
TLC components are still used, which store three bits per cell (triple level cells). With the SSD 990 Evo Plus, however, Samsung is jumping from the sixth generation (V6) to the eighth (V8) with presumably 238 instead of 133 memory layers and higher clock frequencies. This accelerates the data carriers to top speeds of 7.25 GByte/s reading – an increase of 45 percent. The older SSD 990 Evo (without Plus) achieves a maximum of 5 GByte/s.
The IOPS also increase considerably
The write performance also increases considerably, from 4.2 to 6.3 GByte/s. However, the random accesses increase even more: Samsung states values of up to 1.05 million input/output operations per second (IOPS) reading and 1.4 million IOPS writing. The latter value represents an increase of 75 percent.
As usual, the peak values apply to the model with the highest capacity – in the case of the SSD 990 Evo Plus, this is 4 TByte. However, the 1 TByte model is only slightly slower, with 7.15/6.3 GB sequentially and 850,000/1,350,000 IOPS (read/write in each case).
The SSD 990 Evo Plus uses the same Samsung controller called Piccolo as the SSD 990 Evo. It achieves its full speed either with four PCI Express 4.0 lanes or in an M.2 slot with two PCIe 5.0 lanes. The Plus model also does not have its own DRAM cache; however, the data carrier can access a small part of the PC's RAM via the Host Memory Buffer (HMB).
Samsung states a maximum electrical power consumption of 4.3 to 5.5 watts depending on the capacity. When idle, the SSDs should be content with 60 milliwatts. All models support the AES 256 and TCG Opal 2.0 encryption methods.
Samsung specifies a write guarantee of 600 TByte Total Bytes Written (TBW) per terabyte of capacity, i.e. 2400 TBW for the 4 TByte model. The manufacturer's warranty is 5 years.
High recommended retail prices
The recommended retail prices are high as usual for Samsung: 126 euros for one TByte, 211 euros for two and 392 euros for four. Typically, retailers quickly undercut the RRP as soon as the SSDs are available. Delivery is scheduled to begin in October. The first stores are already listing the SSD 990 Evo Plus.
Other 1 TByte SSDs with a read speed of at least 7 GByte/s are already available for less than 70 euros. If you also want the high write IOPS, you can still find it for less than 100 euros (ab 93,92 €).
