This device combination is NOT compatible with the MacPro1,1 MacPro2,1 or MacPro3,1 series. Note about throughput PCIe 2.0 x4 slot or better is required. Use of a PCIe 1.0 x4 slot will reduce performance. 2009-2010 Mac Pro. Installing Accelsior S into any open x4 or x16 PCIe 2.0 slot will deliver full throughput 2008 Mac Pro. These models have two x16 PCIe 2.0 slots, which enable Acceslsior S to deliver full throughput. Installing Accelsior S into of the two x4 PCIe 1.0 slots will result in Accelsior S being addressed as a gen one, one-lane card with performance limited to real world 190-200MB/s data rates. 2006-2007 Mac Pro. These models utilize PCIe 1.0 slot which cannot be configured (even with the Expansion Utility in OS X) to address Accelsior S as anything but as a first generation one-lane card. As a result, Accelsior S performance will be limited to 190-200MB/s data rates. If maximum data rate speedis desired, we recommend the installation of a 2.5" OWC Mercury SSD in an open Mac Pro drive bay.

This Motherboard/system was limited to SATA II (3Gbps) so after buying a Samsung 850 EVO SSD I wanted to get full speed. My system is dual boot (Win 10 & Fedora 25). I installed the card in a PCIe x16 slot that operated at a max of PCIe X4. Basically no issues. I was concern there was going to be an issue with the Samsung SSD being dual boot but definitely plug and play couldn't be easier. I noticed during boot that the PCIe bus speeds registers as PCIe 2.0 x2 and NOT PCIe 2.0 x4 but not an issue as both speeds are faster that SATA III (6Gbps). My speed measured using the Samsung Magician software went from approximate: (284 read, 271 write randoms; 52409 read, 41961 write IOPS on SATA II to 553 read, 526 write; 88649, 71680 respectively with the OWC adapter card). Yes I can tell the difference in boot to both Windows 10 and Fedora Linux is about half but it was very fast anyways after upgrading to SSD from Hard Drive. Windows 10 went from 15 seconds to 8 seconds on the boot while Linux went from 8 seconds to 5 seconds but in the Linux boot there is a program that is configured to take 6 seconds on boot so very fast if I was to turn it off or reduce it! Note: CPU i7 920 OC to 3GHz from 2.6GHz, OCZ DDR3 1333 ram OC from 1066 to 1500 MHz. Graphics is now Radeon RX 460 OC with 2GB Ram, 500W power supply, and 2 DVD drives, Creative XFi sound card and old Zoom modem 3025C that doesn't work with Windows 10. I have one PCIe x16 slot left and 1 old PCI slot left all in a ELITE Mid or Medium tower case. In all honesty I didn't need the upgrade as the system was very fast already for mainly browsing the internet but the OWC card performs as advertised. I would definitely rate this as a buy to extend the life of an older computer. Review: Works well in a Poweredge R710 - Purchased to install in my Poweredge R710. Currently have the 6 drive bays populated, and swapped the optical drive out for a 2.5 inch HDD. I wanted to install a cache SSD in my system for the faster read/writes than my 7200RPM HDDs. Installed this in an available PCIe slot (keep in mind, does not work in the RAID card slot) with a 480GB ADATA SSD. System found the PCIe card on boot, shows BIOS splash for the device and boots right up into unRAID. unRAID reads the drive with it's normal GUID and functions as expected with no issues. The only caveat is the SSD keeps getting a bit warm in my server 60 degrees Celsius and higher, while other components are not. This is most likely an issue with my personal setup and not something with the card itself, but keep in mind that you'll want good ventilation in your system. Works great on a R710 running unRAID. ## Features - Directly mount any standard 2.5-inch hard disk drive or solid-state drive to any PCIe x4 slot - Sustained speeds up to 550 MB/s - Enhance SATA 3G systems with SATA 6G support - Compatible With Mac Pro Mid 2006 - Mid 2012 (MacPro1,1 MacPro2,1 MacPro3,1 MacPro4,1 MacPro5,1), Mac Pro and Mac Pro Rack Late 2019 (MacPro7,1), Xserve Xeon Late 2006-2009 (Xserve1,1 Xserve2,1 Xserve3,1), PC Towers - 3 Year OWC Limited Warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WUZPMHE | | Best Sellers Rank | #153 in Internal Computer Networking Cards #1,535 in Data Storage | | Brand | OWC | | Built-In Media | OWC Accelsior S | | Compatible Devices | Mac Pro Mid 2006 - Mid 2012 (MacPro1,1 MacPro2,1 MacPro3,1 MacPro4,1 MacPro5,1) //Mac Pro and Mac Pro Rack Late 2019 (MacPro7,1), Xserve Xeon Late 2006-2009 (Xserve1,1 Xserve2,1 Xserve3,1) Compatible Devices Mac Pro Mid 2006 - Mid 2012 (MacPro1,1 MacPro2,1 MacPro3,1 MacPro4,1 MacPro5,1) //Mac Pro and Mac Pro Rack Late 2019 (MacPro7,1), Xserve Xeon Late 2006-2009 (Xserve1,1 Xserve2,1 Xserve3,1) See more | | Customer Reviews | 4.6 out of 5 stars 637 Reviews | | Global Trade Identification Number | 00812437021035 | | Hardware Interface | SATA 6.0 Gb/s | | Item Dimensions L x W x H | 8.6"L x 6.3"W x 1.9"H | | Item Weight | 4.8 ounces | | Manufacturer | Other World Computing | | Mfr Part Number | SSDACL6G.S | | Model Number | SSDACL6G.S | | Operating System | Mac OS | | Product Dimensions | 8.6"L x 6.3"W x 1.9"H | | Style | PCIe Card | | Style Name | PCIe Card | | UPC | 812437021035 | ## Product Details - **Brand:** OWC - **Hardware Interface:** SATA 6.0 Gb/s - **Item Weight:** 0.3 Pounds - **Product Dimensions:** 8.6"L x 6.3"W x 1.9"H - **Style:** PCIe Card ## Images ![OWC Accelsior S PCIe Adapter for 2.5-inch SATA 6G Expansion Card Compatible with Mac Pro (2006-2012), Mac Pro 2019 and PC Towers - Image 1](https://m.media-amazon.com/images/I/516KLV1WnyL.jpg) ![OWC Accelsior S PCIe Adapter for 2.5-inch SATA 6G Expansion Card Compatible with Mac Pro (2006-2012), Mac Pro 2019 and PC Towers - Image 2](https://m.media-amazon.com/images/I/51NUY2WABBL.jpg) ![OWC Accelsior S PCIe Adapter for 2.5-inch SATA 6G Expansion Card Compatible with Mac Pro (2006-2012), Mac Pro 2019 and PC Towers - Image 3](https://m.media-amazon.com/images/I/51IeEWEBBdL.jpg) ![OWC Accelsior S PCIe Adapter for 2.5-inch SATA 6G Expansion Card Compatible with Mac Pro (2006-2012), Mac Pro 2019 and PC Towers - Image 4](https://m.media-amazon.com/images/I/41HnvWyQ3rL.jpg) ![OWC Accelsior S PCIe Adapter for 2.5-inch SATA 6G Expansion Card Compatible with Mac Pro (2006-2012), Mac Pro 2019 and PC Towers - Image 5](https://m.media-amazon.com/images/I/51OC6Ye6vfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Installed in a MSI X58 Pro 1366 socket with tri-channel ... *by A***C on January 29, 2017* Installed in a MSI X58 Pro 1366 socket with tri-channel memory, a system I built in 2009.

The instructions were simple and easy to follow. Very impressive and ordered another card for my 2009 Mac Pro 4,1 upgraded to the 5,1 model recently CPU upgrade from single 2.93 GHz to 3.46 GHz. It is performing exceptionally well with this card and SSD in the PCIe slot as the boot drive in my Mac Pro. The boot time has been exceptionally fast and application response time is much quicker than HDD and the computer is quieter and cooler than ever before. The card comes with the four screws to attach the SSD and instruction and requires no drivers and it’s just simple plug the card along with the SSD into PCIe slot and boot your Mac Pro as you see fit. You would actually see the results as it begins to boot up. Also, I do not use neither of my Mac Pros for gaming so I can not see fit to talk about that agenda. ## Frequently Bought Together - OWC Accelsior S PCIe Adapter for 2.5-inch SATA 6G Expansion Card Compatible with Mac Pro (2006-2012), Mac Pro 2019 and PC Towers - OWC Mount Pro 2.5" Drive Sled Compatible with 2009-2012 Mac Pro - OWC Hard Drive Sled/Bracket for Mac Pro 2009-2012 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/15473598-owc-accelsior-s-pcie-adapter-for-2-5-inch-sata](https://www.desertcart.tn/products/15473598-owc-accelsior-s-pcie-adapter-for-2-5-inch-sata) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-30*
