Kioxia, the company formerly known as Toshiba, has started to ship a new storage device based on a new form factor, XFMEXPRESS, which aims to bring the best of both SSD and microSD worlds.
Lub XT2 yog PCIe tshem tau txuas nrog NVMe cia khoom uas, raws li Kioxia cov ntaub ntawv kev lag luam, yuav "txhim kho cov ntawv txuas ntxiv mus thiab cov ntawv sau cia".
Cov thev naus laus zis - uas yog peb xyoos hauv kev tsim - yog tshem tau zoo li daim npav microSD, nrog qhov ntev (18 x 14 x 1.4mm) me ntsis loj dua tom kawg (14 x 11 x 1mm). Nws cov connector zoo ib yam li cov xov tooj smartphones siv rau nano SIM phaib, xav kom lub hau npog yuav tsum tau swb ib sab kom nkag mus rau daim npav.
Tus cev lus rau lub tuam txhab tau hais TechRadar Pro tias XT2 yuav raug nqi sib tw nrog lwm yam SSD daim ntawv ntawm kev ua tau zoo sib xws thiab yuav muaj nyob rau hauv qhov muaj peev xwm xws li 128GB txog 1TB. Raws li rau kev nrawm, muab hais tias nws los nrog PCIe Gen 4 x 2 txoj kab, kev nyeem thiab sau ntawv yuav tsum ntau dua 2500Mbps thiab 650Mbps feem.
Ib tus sib tw rau microSD?
Don’t expect XFMExpress to replace microSD any time soon, even if demand for the tiny cards has taken a downward trajectory as mainstream smartphones abandon removable storage altogether.
Kuj tseem muaj qhov teeb meem cuam tshuam nrog kev sib tw hom SD Express, uas kuj yog tus qauv PCIe NVMe, uas tuaj yeem ncav cuag li 4GBps, muaj cov yam ntxwv ruaj ntseg siab heev thiab txhawb nqa los ntawm SD koom haum.
Uas coj peb mus rau lo lus nug ntawm seb lub lag luam puas xav tau lwm daim ntawv tshiab, thaum cov txiaj ntsig uas twb muaj lawm los ntawm kev txhawb nqa kev lag luam loj, kev ua tau zoo dua, kev kho me me thiab kev ruaj ntseg zoo dua. Peb tau muab lo lus nug ntawd rau Kioxia thiab yuav hloov kho tsab xov xwm thaum peb hnov rov qab.
As for use cases that require high performance, high capacity storage, there’s plenty (e.g. prosumer cameras, IoT/edge servers etc.), but they are likely to be niche and unlikely to sustain a market where rival formats exist.
