3/15/2023 0 Comments Softraid for mac![]() ![]() The SSD7540 I have today is part of the SSD7500 series cards, available in 2, 4, or 8 port capacities. Most of what you see on the rear of the card is part of the M.2 mounting points. HighPoint SSD7540 BackĬompared to the front of the SSD7540, the rear has almost nothing going on. For users that demand even faster performance, HighPoint has a technology they call ‘Cross-Sync RAID’ that allows you to utilize a pair of SSD7540 cards in tandem for double the performance, though this is not something we tested. The connection to the host interface is a PCIe 4.0 x16 slot, so there is a 2:1 lane oversubscription at play, but there is clearly a lot of bandwidth available. That is because fundamentally we are dealing with a software-based RAID solution. Other than the large PCIe switch chip, there is no controller on this card. The main advantage of using a PCIe switch chip like this is that bifurcation is not required on the PCIe slot where this card is connected. This chip hosts enough PCIe lanes to allow each individual M.2 SSD their own dedicated PCIe 4.0 x4 lanes. HighPoint SSD7540 Front Cover Thermal PadsĮight PCIe 4.0 x4 M.2-2280 slots flank the Broadcom PEX88048B0 PCIe switch chip in the center. ![]() Removing the heatsink reveals the good stuff inside. On the end of the card, we have one of the fan connections, as well as a 6-pin power connector. M.2 SSDs are known to generate quite a bit of heat, and 8x of them will definitely require active cooling. The front of the SSD7540 is dominated by its large heatsink equipped with twin fans. The first impression I had of the SSD7540 was simply its size this card is very large. This review is the first in a series of PCIe M.2 RAID cards, so stay tuned for future reviews! For now, let us see how the SSD7540 fares. Sabrent participated in this review by graciously providing eight of their Rocket 4 Plus 2TB drives, and I am very grateful to them as it would be hard to review something like this without fully populating the card with identical drives. This is a full-height PCIe 4.0 x16 card that is host to 8x PCIe 4.0 M.2-2280 slots, and allows RAID 0, 1, and 10 functionality. Incredible Thunderbolt 2 performance over 1.Today I am taking a look at the HighPoint SSD7540 PCIe Gen4 M.2 RAID card.Exponentially faster rebuild times than hardware RAID.Up to 506MB/s read / 520MB/s write RAID 0 performance.Up to 332MB/s read / 315MB/s write RAID 5 performance.Only RAID 0 and RAID 1 are supported by Windows 10/PC. ![]() based support for both the ThunderBay 4 drive and SoftRAID XT software.īuyers note: RAID 4/5/1+0 (10) are currently Mac only. ![]() Should you ever have a question or troubleshooting need, you can rely on OWC's award-winning U.S. SoftRAID XT is extremely flexible and can easily be updated, reconfigured and used across multiple enclosures to provide an amazing amount of robust options to empower you to make the most of your ThunderBay workflow. ThunderBay 4 and the SoftRAID engine offers faster performance than many competing 4 or even 5-bay hardware RAID external drives – benefiting from modern processors that are both fast and designed for exceptionally high-performance RAID management with no real-world impact on apps or tasks. Helping you to maintain mission critical workflows. SoftRAID XT lets you easily setup drive monitoring and e-mail notifications to keep you informed about your ThunderBay's performance and drive health. SoftRAID XT combines advanced RAID modes, fast performance, monitoring, e-mail notification, and fast rebuild capabilities that only software RAID can deliver. Over a year ago, OWC partnered with SoftRAID to bring enhanced storage capabilities to the Mac, and we're now seeing that dream become a reality. Hardware RAID has long been thought to be superior to software RAID, but we've now combined the massive performance and capacity of ThunderBay 4 with a robust, proven software RAID engine to provide breathtaking performance, flexibility, and reliability. Activate advanced features, such as drive monitoring, e-mail notifications, and more when you install the included SoftRAID XT for macOS. Empower your workflow with up to 35% faster RAID 5 performance and exponentially faster rebuild times than comparable hardware based RAID arrays. Experience the first and only software RAID 5 technology developed for the Mac with the SoftRAID XT. ![]()
