Gigabyte Unveils 4-Way PCIe 5.0 SSD Adaptor With Up to 60 GBps
Gigabyte's Aorus Gen5 AIC adapter has four M.2 slots
Last week, Gigabyte was among the first companies to introduce a client solid-state drive (SSD) featuring a PCIe 5.0 x4 interface. Gigabyte's Aorus Gen5 1000 SSD is currently among the highest performing storage devices that currently exist, but there are applications and users who demand even higher speeds. Specifically for those workloads and users, Gigabyte on Tuesday revealed its 4-way PCIe Gen5 SSD adapter that in theory can quadruple storage performance and capacity.
Gigabyte's Aorus Gen5 AIC Adapter with PCIe 5.0 support is a full-height full-length PCIe x16 card that carries four M.2-2280 SSDs with a PCIe 5.0 x4 interface that work in a RAID configuration. Depending on the RAID mode set by the owner, the Aorus Gen5 AIC Adapter can provide up to 16TB of storage (at least when used with four Aorus Gen5 1000 drives) and sequential read/write performance of up to 60 GB/s, which is significantly higher than even the best SSDs offer.
The Aorus Gen5 AIC Adapter is said to feature a separate PCIe 5.0 controller (or switch?) to ensure maximum performance. It also has a sophisticated cooling system with thermal sensors and a fan to ensure consistent performance under high loads.
The Aorus Gen5 AIC Adapter is meant to be installed into desktops featuring a PCIe 5.0 x16 slot, so you'll need at least an AMD's Ryzen 7000-series or Intel's 12th or 13th Generation Core CPU platform, but there's a catch. Modern processors for client desktop PCs only support 20 PCIe 5.0 lanes, 16 lanes for a graphics card and four lanes for an SSD. Some systems feature two PCIe x16 slots with each working in x8 mode, so they can install a graphics board and Gigabyte's 4-way SSD adapter, but this means that neither of the cards will get full PCIe 5.0 x16 bandwidth.
Truth to be told, few people need a storage device with a ~60 GB/s of bandwidth. Perhaps workstation users who process ultra-high-definition videos would benefit from such a high sequential read and write speed. For most people, high random read and write performance will be enough for comfortable work. Those who buy 4-way SSD adapters are indeed looking for extreme storage performance.
Gigabyte has not disclosed pricing for its Aorus Gen5 AIC Adapter, but considering the fact that it has its own switch and an advanced cooling system, not to mention the target market, it will likely be a rather expensive product.

teodoreh Original Samsung commercial with 24 SSDs had a performance of 2GB/sec (although in theory it should had 13.2Gbps/s).Reply
Now you can create a CHEAP array with 60Gbps. What a world we live in! -

You will need to purchase xeon or threadripper pro workstations for that. -

60GBps is possible only during sequential read/write and in raid 0. Since nobody in their right mind will use raid 0 (raid 5 is next best) you will get around 45 GBps max. This is provided you are reading to ram and writing from ram. -

Presumably the xor would happen off card for RAID5 which would kill performance. Likely RAID10 at half the capacity and performance is the next best thing to RAID0 for this card.escksu said:60GBps is possible only during sequential read/write and in raid 0.

I've always run SSDs in RAID 0, mostly because I was afraid that write amplification would be faster to kill them than a typical HDD-type single drive failure.
It's an old discussion and SAN vendors like Pure have simply moved on to far more sophisticated flash redundancy algorithms than RAID.
But for the more consumer type setups the issue hasn't been properly resolved to my knowledge.
SSD controller failures are chip failures. They inevitably do happen, but just like CPU failures, they should be extremely rare and they are not what typically killed HDDs.
Yet the type of media or head failures that created the demand for RAID simply can't happen on SSDs, where the media is flash chips, which are already run as 'flash aware RAIDs' within the SSD.
Adding another, non-flash aware RAID outside risks adding the write amplification which can very easily exhaust flash chips when it's not aware of them. Even hardware RAID controllers which already are rather helpful at reducing write amplifications on HDDs via battery buffered caches that will prefer to only write back full stripes weren't helping much, either because those caches were too small to accomodate the far larger erase blocks or because they quite bypassed their BBU cache for SSDs.
Now in-place single block updates, which are the worst case for write amplification, may not really be all that frequent unless you happen to run a file-based DB, so perhaps I'm too worried. But on SSDs writes reliably deteriorate media. If your SSD is full and single block updates trigger full erasure blocks being rewritten, they hurt badly. And when the media failure is already covered by the SSD controller, I just don't see why I should mistreat them.
It helps that most of my SSDs are really just caches, which can be rebuild from cloud or HDD data.
But yes, given that very few desktop computers will actually manage 60GB/s sustained transfers to RAM, these numbers are hard to obtain even with synthetic tests. -
