M3 MacBook Airs Have Faster 256GB Storage Than M2 Models But Varying Speeds Overall
• M3 MacBook Air 256GB models appear to use faster storage with 2x 128GB chips instead of 1x 256GB chip like M2 Airs
• This results in 256GB M3 Airs having nearly 2x the read/write speeds of 256GB M2 Airs
• 512GB+ M3 Airs have similar speeds to 512GB+ M2 Airs, around 3,000 MB/s read/write
• But storage speeds can vary between models depending on suppliers & prices for Apple
• It's disappointing base storage speed hasn't really improved since M1 Airs launched 3+ years ago
