What you need to know
- Sabrent debuted the new Rocket 4 Plus PCIe 4 SSD this week.
- The drive takes the top spot as the world's current fastest drive.
- There's no word yet on when the Rocket 4 Plus will be available or how much it will cost.
The world of PCIe 4 SSDs already has plenty of speed demons, but Sabrent just took the crown. The company's new Rocket 4 Plus SSD sports the fastest combination of read and write speeds currently available, beating out even Samsung's latest 980 Pro PCIe 4 NVMe drive (via PC Gamer).
Both drives would probably make any list of the best SSDs, but Sabrent manages to just squeeze out the edge. The Rocket 4 Plus matches the Samsung 980 Pro's 7,000 MB/s read time, but it surpasses Samsung's drive with a 6,850 MB/s write speed. The Samsung drive, for comparison, reaches maximum write speeds of 5,000 MB/s.
According to Sabrent's Rocket 4 Plus product page, it will be available in 2TB, 1TB, and 500GB capacities. That's a far cry from the largest PCIe 4 SSD out there, a 4TB monster also made by Sabrent. However, in exchange for the lower capacities, you're getting vastly superior maximum read and write speeds. Sabrent also shrouds the Rocket 4 Plus in a beefy custom heatsink to keep the drive running cool.
Sabrent hasn't provided a release date or pricing information yet, but we'll likely hear more soon.

Forget speed, what about reliability?
Time will tell. Nothing will last forever and then we have the race to stay ahead.
Look at the TBW numbers. That's the number of writes in terabytes that the drive can have before it starts to fail and it's own garbage collection can't cope. The drive won't die a that point, but the drive will start to 'soon' after wards depending on how much data is already on it and how much you're writing to it. SMART should give you a very good idea of how much life you have in your drive still. One of the cheapest drives, like the Crucial BX500 (120GB) SSD has a 40 Terabytes Written (TBW) lifecycle. This means they expect and can be fully over written with 120GB of data around 330 times (at the lower end of the scale, up to 35,000 for better drives) before they start to die. To put that into perspective. You could fill the SSD up every single day for almost a year before the drive start fail due to being worn out. I don't know about you, but I don't have 40TB of anything to write to a SSD. Keep in mind that just reading data from the drive doesn't wear them out. Most of the SSD drives on the market today are going to be replaced because die of other failures, or simply be upgraded for better speed and capacity. My SSD (A cheap SanDisk X110 / 80TBW) in my main PC has a power on time of 3 years, 59 days 22 hours. Smart estimates more than 670 days left on the drive, and it's had 30.42TB written to it. I have not been kind to my drive by any means. I extract files on it, edit movies, download to it etc. I probably won't expect another 2 years out of it, as I'll be replacing it this year at some point, 100gb of space isn't much these days. But it could easily run for many more years than that if all I was using it for was to store games, and play them.
Thanks for that explanation. I kind of learned that over the past couple of years by reading on them, but I never heard about there being an actual lifespan number. The question was really posed regarding brands and reliability. I have seen some really cheap SSDs out there have horrible ratings for failures, but I don't actually know of it is true of anecdotal evidence like me having seen more Seagate HDs die than others.
Well dang. Take my wallet!
