While the Acer brand is most known in the computer market, these cards are designed and manufactured by BIWIN Storage Technology, which produces its own line of solid state storage and DRAM memory modules, as well as HP-branded hardware through a license, which is what it’s doing with the Acer Storage brand and these new CFexpress Type B cards.
The Acer Storage CFexpress Type B memory cards are available in 128GB, 256GB and 512GB capacities. All capacities top out at 1,600MB/s sequential read speeds. The sequential write speeds of the 128GB and 256GB models top out at 1,000MB/s while the 512GB version maxes out at 1,200MB/s. As with all CFexpress Type B memory cards, these use a PCIe Gen3x2 interface and are backwards compatible with select cameras with XQD card slots.
Acer Storage says the cards are UB-guarded, magnet-proof, X-ray proof and anti-static. As for environmental conditions, they’re rated for working between -20°C (-4ºF) and 70°C (158ºF) and can be stored in temperatures as low/high as -40ºC (-40ºF) and 85°C (185ºF).
As is the case with most CFexpress Type B cards, these Acer Storage models don’t come cheap when breaking it down by cost-per-gigabyte. However, the prices are in line with other CFexpress Type B cards on the market, including those offered by SanDisk and ProGrade. The 128GB, 256GB and 512GB Acer Storage CFexpress Type B cards will be avaialble to purchase for $130, $270 and $460, respectively.
