Samsung's 990 PRO, its latest NVMe PCIe 4.0 SSD, aims to give gamers, 3D-renderers, and 4K/8K video editors a decent ratio of price to performance if this top-of-the-line drive can get close to its promised specs in real-world testing.

The 990 PRO is touted as offering "nearly the highest speed currently available from the new PCIe 4.0 interface" and a 55 percent increase in random performance over its 980 Pro . Samsung touts sequential read and write speeds of 7,450 megabytes per second (MB/s) and 6,900MB/s, respectively. Random read/write speeds are listed at 1,400K and 1,550K IOPS, respectively, based on IOmeter 1.1.0 performance. DRAM for the 990 PRO drives is 1GB per terabyte of storage, up to 4GB for the 4TB model.

Samsung suggests the performance bump comes from its own V-NAND and proprietary controller advancements. Power efficiency is improved up to 50 percent over the 980 PRO, the company claims, while a nickel coating and heat-spreading label dissipate heat. The heatsink model gives you more temperature assurance while, of course, adding RGB lights.

    Face au M1, le SSD du MacBook Pro M2 réserve une mauvaise surprise

    news.movim.eu / JournalDuGeek · Friday, 1 July - 07:30

Le MacBook Pro M2 est disponible depuis quelques jours et l’ensemble de ces caractéristiques sont passés au peigne fin. Son SSD se révèlerait bien moins véloce que celui de son prédécesseur doté de la puce M1.

    M2 MacBook Pro’s 256GB SSD is only about half as fast as the M1 version’s

The use of the M2 chip is the new 13-inch MacBook Pro's biggest change compared to the M1 version Apple launched in 2020, but it's apparently not the only one. YouTubers on the Max Tech and Created Tech channels (via MacRumors ) have run speed tests on the 256GB version of the M2 MacBook Pro and discovered that the SSD's read and write speeds are as much as 50 percent slower than the 256GB SSD in the M1 MacBook Pro.

Sustained disk read speeds run by Max Tech using the BlackMagic Disk Speed Test showed a drop from about 2,900MB/s in the M1 MacBook Pro to 1,446MB/s in the M2 MacBook Pro. Write speeds dropped from 2,215MB/s in the M1 Pro to 1,463MB/s in the M2 Pro, a smaller but still significant drop.

The culprit appears to be the NAND flash configuration. Both YouTubers took the bottom off of the new MacBook Pro and discovered that the 256GB versions use just one 256GB NAND flash chip, whereas the M1 MacBook Pro uses a pair of 128GB flash chips. On drives with more physical NAND chips, SSD controllers use a process called interleaving to read data from and write data to multiple physical chips at once. Use fewer chips, and you can limit your peak performance.
