The Samsung 990 Pro
is a solid-state drive in the M.2 2280 form factor, launched on August 24th,
2022. It is available in capacities ranging from 1 TB to 2 TB. This page
reports specifications for the 1 TB variant. With the rest of the system, the
Samsung 990 Pro interfaces using a PCI-Express 4.0 x4 connection. The SSD
controller is the Pascal (S4LV008) from Samsung, a DRAM cache chip is
available. Samsung has installed 176-layer TLC NAND flash on the 990 Pro, the
flash chips are made by Samsung. Please note that this SSD is sold in multiple
variants with different NAND flash or controller, which could affect
performance, the "Notes" section at the end of this page has more
info. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming
writes are soaked up more quickly. The cache is sized at 114 GB. Thanks to
support for the fast PCI-Express 4.0 interface, performance is excellent. The
990 Pro is rated for sequential read speeds of up to 7,450 MB/s and 6,900 MB/s
write; random IOPS reach up to 1200K for reads and 1550K for writes.
At its launch, the
SSD was priced at 179 USD. The warranty length is set to five years, which is
an excellent warranty period. Samsung guarantees an endurance rating of 600
TBW, a typical value for consumer SSDs.

| crucial |
The Crucial P3 Plus
is a solid-state drive in the M.2 2280 form factor, launched on May 25th, 2022.
It is available in capacities ranging from 500 GB to 4 TB. This page reports
specifications for the 1 TB variant. With the rest of the system, the Crucial
P3 Plus interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is
the PS5021-E21T from Phison, a DRAM cache is not available. Crucial has
installed 176-layer QLC NAND flash on the P3 Plus, the flash chips are made by
Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of
incoming writes are soaked up more quickly. The cache is sized at 250 GB.
Copying data out of the SLC cache (folding) completes at 100 MB/s. Thanks to
support for the fast PCI-Express 4.0 interface, performance is excellent. The
P3 Plus is rated for sequential read speeds of up to 5,000 MB/s and 3,600 MB/s
write.
At its launch, the
SSD was priced at 100 USD. The warranty length is set to five years, which is
an excellent warranty period. Crucial guarantees an endurance rating of 220
TBW, a relatively low value compared to other SSDs.

The Kingston KC3000
is a solid-state drive in the M.2 2280 form factor, launched in October 2021.
It is available in capacities ranging from 512 GB to 4 TB. This page reports
specifications for the 1 TB variant. With the rest of the system, the Kingston
KC3000 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is
the PS5018-E18-41 from Phison, a DRAM cache chip is available. Kingston has
installed 176-layer TLC NAND flash on the KC3000, the flash chips are made by
Micron. Please note that this SSD is sold in multiple variants with different
NAND flash or controller, which could affect performance, the "Notes"
section at the end of this page has more info. To improve write speeds, a
pseudo-SLC cache is used, so bursts of incoming writes are processed more
quickly. The cache is sized at 369 GB, once it is full, writes complete at 1900
MB/s. Copying data out of the SLC cache (folding) completes at 1015 MB/s.
Thanks to support for the fast PCI-Express 4.0 interface, performance is
excellent. The KC3000 is rated for sequential read speeds of up to 7,000 MB/s
and 6,000 MB/s write; random IOPS reach up to 900K for reads and 1000K for
writes.
At its launch, the
SSD was priced at 175 USD. The warranty length is set to five years, which is
