Samsung made
headlines after it launched the 4TB solid state drive (Evo series) a
couple of years ago at a retail price of Rs 10,300 (around
$1,499). The company has now announced an affordable lineup in the
form of 4TB QLC (quad level cell) SSD’s.
Bits
per Cell - 4-bit QLC |
Nodes - 4th generation V-NAND
(undisclosed lithography) | Chip Capacity – 1Tb
| Drive Capacity - 4Tb
The QLC NAND often
takes flak for being slower. However, in this case, Samsung has
promised that the device will offer 540Mbps read and 520Mbps write
data which is identical to the speeds offered by the SATA SSD
drives. Samsung is also offering a 1TB and 2TB variant, both of which
will be priced at an affordable price point. The new QLC SSD’s will
come accompanied with three-year warranty by Samsung.
Interestingly,
Samsung will be using the QLC technology “to efficiently produce
a 128GB memory card for smartphones that will lead the charge toward
higher capacities for high-performance memory storage.”
Needless to say, Samsung is likely to use this technology for its
upcoming smartphones including the 512GB Galaxy Note 9. The storage
devices have been bucking the trend, the need for memory cards seems
to be going down at a time when phones are coming equipped with half
a TB, or in some cases even 1TB of internal storage.
The 4TB QLC SSD is
expected to be launched by the end of this year. Samsung might end up
pricing the storage device competitively so that customers who prefer
disk volume to speed will prefer the QLC SSD. Thanks to the QLC
technology the data stored within a memory cell is increased from
three bits to four bits. As a direct result of an increase in
density, the chip capacity per unit area will increase and power
required by the SSD will decrease drastically.
