KIOXIA America has unveiled the EG7 Sequence, a brand new household of consumer SSDs that brings its BiCS FLASH technology 8 QLC with CMOS immediately Bonded to Array (CBA) expertise to this phase for the primary time. KIOXIA says the brand new sequence is designed to assist PC producers deliver high-performance, power-efficient storage to a wider vary of programs at a extra accessible worth level. Capability choices will embody 512GB, 1TB, and 2TB fashions.
KIOXIA EG7 Sequence Efficiency and Predominant Options
The EG7 Sequence makes use of 4-bit-per-cell (quadruple-level cell) NAND flash. QLC storage is often utilized in lower-cost programs, although it has lengthy confronted skepticism about whether or not it will possibly maintain tempo with TLC-based drives in on a regular basis efficiency. KIOXIA is positioning the EG7 Sequence as a response to that skepticism, saying the brand new SSDs can ship TLC-level efficiency whereas decreasing the whole value of possession for PC makers constructing mainstream and extra price-conscious programs.
For efficiency, the drives supply as much as 1,000 KIOPS for random reads and writes. Sequential learn speeds attain as much as 7,000MB/s, whereas sequential write speeds go as excessive as 6,200MB/s. This locations the EG7 Sequence within the vary of contemporary PCIe Gen4 consumer SSDs.
The EG7 Sequence additionally helps the NVMe 2.0d specification, which KIOXIA says will present PC OEMs with added flexibility in gadget administration and general system design.
KIOXIA EG7 Sequence Type Components, Design, and Safety
KIOXIA is providing the drives in a number of M.2 type components: Kind 2230, Kind 2242, and Kind 2280. That vary permits the EG7 Sequence to slot in compact gadgets with tight board area, in addition to in additional typical pocket book and desktop configurations. The smaller 2230 and 2242 codecs are necessary as a result of thin-and-light programs and compact PCs typically use shorter SSD layouts.
| Metric | 512GB | 1024GB | 2048GB |
|---|---|---|---|
| Sequential Learn | 6,400 MB/s | 7,000 MB/s | |
| Sequential Write | 5,000 MB/s | 6,000 MB/s | 6,200 MB/s |
| Random Learn | 550,000 IOPS | 850,000 IOPS | 1,000,000 IOPS |
| Random Write | 850,000 IOPS | 950,000 IOPS | 1,000,000 IOPS |
The EG7 Sequence additionally makes use of a DRAM-less design. Slightly than counting on onboard DRAM, the drives use Host Reminiscence Buffer (HMB) expertise, which faucets right into a portion of system reminiscence to assist handle SSD capabilities. This design is frequent in additional budget-conscious storage merchandise, and may help decrease the whole value of possession and cut back energy use with out sacrificing responsive efficiency.
The drives assist TCG Opal model 2.02 self-encrypting drive performance, which is necessary for enterprise programs that require hardware-based safety.
Storage distributors are pushing higher-density flash right into a wider vary of gadgets as producers search extra capability with out including important system prices. So, the EG7 Sequence provides OEMs an alternative choice for mainstream PCs that have to stability efficiency, energy effectivity, and affordability.
KIOXIA EG7 Sequence Availability
The EG7 Sequence is at present sampling with choose PC OEM clients. Techniques with the brand new SSDs are anticipated to start transport within the second quarter of 2026.
