Hard drive and SSD upgrades for each Apple MacBook Pro with complete specs. Includes storage speed, hard drive size and dimensions, SSD specifics, identifiers and more. Thank you for sharing your experience, and I also want to share mine: I bought a used MacBook Pro 13 Early 2015 some 3 years ago, with Apple SSD 128 GB. One year ago I decided to upgrade my device. One year ago I decided to upgrade my device. posted on May. 21, 2015. In addition to getting the new Force Touch trackpad, the new 15” MacBook Pro with Retina display also received faster PCIe-based flash storage, which Apple says is up to 2.5X faster than the previous generation. After unboxing the new model, OWC has tested the new SSD in QuickBench 4.0. Retina display: 13.3-inch (diagonal) LED-backlit display with IPS technology; 2560-by-1600 resolution at 227 pixels per inch with support for millions of colors. Native resolution: 2560 by 1600 pixels (Retina); scaled resolutions: 1680 by 1050, 1440 by 900, and 1024 by 640 pixels. System specs; 2.7 GHz Intel Core i5. 16 GB 1867 MHz DDR3. 256 GB SSD. Intel Iris Graphics 6100 1536MB. I conducted the disk speed test from Blackmagicdesign and was unpleasantly surprised to see that the write speed is lagging at around 560 MB/s and read at 1000MB/s as other owners are reaching both write and read speeds at around 1200MB/s I have experience with two Early 2015 13" Macbook Pros, one with factory 128GB SSD, and another with a factory 512GB SSD. The size of the SSD seems to make a difference with Write Anyway, I'll not fill this report only in this specific case, from Big Sur to Monterey. Machine: Retina MacBook Pro 13", early 2015, A1502, RAM 8gb, Intel Iris 6100. NVMe: Kingston A2000 1TB SA2000M8/1000G + SINTECH Adapter. Time since installation: 2 months. I have bitten the bullet and decided to upgrade the ssd in my late 2013 15” MacBook Pro. It currently has the 512GB SSD running Big Sur with 427 firmware. Has windows 10 running through bootcamp. I have ordered the Sabrent Rocket 2TB and the sintech adapter off Amazon. The Rocket Q 2TB is £20 more but being PCie 4.0 not really necessary. The results show that the flash drive in the 2015 MacBook Pro leaves the late 2013 MacBook Pro far behind (ditto for the 2013 Mac Pro). Moreover, this translates into huge gains in performance for some tasks where I/O is a big factor (see following pages of this review). Some real-world considerations as to how much faster real work might go: MacBook Pro retina 15" mid 2015 : works from 10.10.3 (PCIe 3.0 speed 4x lanes) As for non-Apple NVMe drives, (Samsung 960 evo/pro etc) : Mac Pro late 2013 : works from 10.13 (PCIe 3.0 speed 4x lanes) MacBook Air 11" & 13" mid 2013 : works from 10.13 (PCIe 2.0 speed 2x lanes) MacBook Pro retina 13" late 2013 :works from 10.13 (PCIe 2.0 speed 2x wtbbkP.
