Sabrent’s Rocket Q4 is a half-sized (37.5 percent actually), 2230 (22mm wide, 30mm long) NVMe SSD. Because it’s so small, it can be used in devices, such as a Steam Deck or Mini-PC, that lack space for a full 2280 SSD.
But the real news is that it’s amazingly fast in the real world—even compared to PCIe 5.0 drives. Skeptical? We were. But when extended testing garnered the same exceptional results, we were more than pleasantly surprised.

Sabrent Rocket Q4 design and featuresI’ve already mentioned the Q4’s diminutive dimensions. It’s also a PCIe 4.0, NVMe 1.4 SSD that utilizes Micron’s brand-spanking-new N48 QLC NAND and Phison’s latest E21T controller. I talk those up because they’re the reason for the amazingly facile real-world transfers—far outpacing any previous PCIe 4.0 SSD we’ve tested.
The Q4 is also a DRAM-less, HMB (Host Memory Buffer) design. That is, it forgoes using DRAM for primary cache (there’s really no place to fit it), and instead uses your system memory for that duty.
HMB is a relatively new cost-saving technology that’s improving with every iteration. Of course, its efficiency will depend somewhat on the speed of your memory subsystem. Our new testbed with its faster 4,800MHz DDR5 memory will definitely deliver higher HMB numbers than the old 3,200MHz DDR4 system, so you can’t directly compare results with our older HMB reviews.
On Amazon at the time of this writing the Q4 is available in $44.99/256GB, $76.49/512GB, $109.99/1TB, and $219.99/2TB (tested) capacities. That’s hardly bargain bin, but it’s not premium-priced either. Given the small form factor and performance, it’s a fair deal.
Sabrent warranties the Q4 for an unqualified five years (two years without registration). Unqualified is a good thing because the TBW rating (terabytes that may be written) for the 2TB SSD is a minuscule 450TBW. That’s a fair amount of data in the grand scheme, but less than half the norm.
If you’re not familiar, the TBW rating can be used like the mileage in an automobile warranty, ending the coverage period early if it’s exceeded.
In this case, Sabrent says it honors the warranty period without question, only denying users who try to run scams such as putting a Sabrent label on another, cheaper drive. Yes, there’s always someone!
When it comes to sustained write speeds, the Sabrent Rocket Q4 is faster than even PCIe 5.0 drives, shockingly.
How does the Sabrent Rocket Q4 perform?There was a huge discrepancy between the Q4’s synthetic benchmark results, and its times in our 48GB and 450GB transfers. At least in the context of previous SSDs we’ve previously reviewed. The synthetics showed the Q4 to be what it ostensibly is–a mid-tier QLC PCIe 4.0 SSD.
However, the Q4 blew through our real-world 48GB and 450GB transfers almost as quickly as the fantastically facile PCIe 5.0 Crucial T700, and actually beat out the Gigabyte PCIe5 10000 by a healthy margin.
Talking to Phison, it seems that Micron’s new N48 NAND is simply blazing in pSLC mode (pseudo Single Level Cell/1-bit) and the E21T controller itself improves HMB performance. Whatever the reason, we indeed saw real-world sustained transfer speeds from the Rocket Q4 that we’ve only seen with the latest PCIe 5.0 drives.
The CrystalDiskMark 8 numbers shown below are certainly nothing special, and hardly the best we’ve seen from a PCIe 4.0 SSD. Note how much faster the PCIe 4.0 WD SN850X would appear to be.
Longer bars are better, and the Rocket Q4 doesn’t seem like it should be grouped with these drives given these results. See the next two charts for the reason why.
But our jaws nearly hit the floor when we ran the 48GB transfer tests. The Q4 took second place among all the drives we’ve tested–far outpacing the WD SN850X, our previous top PCIe 4.0 drive.
This is a fantastic performance for a PCIe 4.0 drive. Shocking according to previous results, in fact.
Jaws dropped even further when we saw the result of the 450GB write. The Q4 actually displaced the previously unbeaten T700. Yup. The Rocket Q4 is the fastest single SSD at this task we’ve ever tested. Stunning to say the least.
Number one? Yowser. This we were not expecting, but apparently the new Micron N48 NAND is speedy indeed in pSLC mode. I.e., writing single bits.
Note, however, that 450GB is generally not enough to exhaust secondary cache on a 2TB or greater SSD these days, so we resort to additional 450GB writes until secondary cache is exhausted. Despite the chart, the test is less about speed than to see how well secondary caching is handled, and the native write speed of the NAND once it runs out.
Also, the above results were all gathered using a pristine, empty 2TB drive. Any time the Q4 ran out of secondary cache (pSLC), writes dropped precipitously to below 100MBps. Yikes. That would be after after several long writes, and/or smaller writes with the drive not having time to clear cache by rewriting data in native QLC 4-bit mode. The drop-off will also occur significantly sooner with lower-capacity models.
The reason QLC is so deadly slow when writing natively is the finesse and error checking required to accurately store one of 16 voltage levels to a cell. But be aware that this is a write phenomenon only. Read speeds remain relatively consistent no matter how much data is on the drive.
Should you buy the Sabrent Rocket Q4?For those with average needs, and for most applications, the Sabrent Rocket Q4 is a marvelous drive with fantastically fast real-world sustained performance. At least in the 2TB capacity.
If you don’t have PCIe 5.0, or don’t write very large amounts of data constantly, it should absolutely be at the top of your short list–even if you have space for a 2280 model.
How we test:
Internal drive tests currently utilize Windows 11 64-bit running on an X790 (PCIe 4.0/5.0) motherboard/i5-12400 CPU combo with two Kingston Fury 32GB DDR5 4800MHz modules (64GB of memory total). Intel integrated graphics are employed. The 48GB transfer tests utilize an ImDisk RAM disk taking up 58GB of the 64GB of total memory. The 450GB file is transferred from a Samsung 990 Pro 2TB which also runs the OS.
Each test is performed on a newly formatted and TRIM’d drive so the results are optimal. Note that in normal use, as a drive fills up, performance will decrease due to less NAND for secondary caching, as well as other factors.

Wd’s My Passport Ssd Review: Worthy Competition For Samsung’s T3
This external USB 3.1 10Gbps SSD is small, fast, good-looking and capacious. It’s a great product, but it’s slower with smaller files and folders than its main competitor–Samsung’s similarly expensive T3.
Until WD’s My Passport SSD showed up on our doorstep, Samsung’s T3 USB 3.1 (Gen 1, 5Gbps) portable SSD was the last word in super-svelte, high-capacity storage. Now there’s at least a conversation. The My Passport SSD even adds a little spice to the debate by using a Type C USB 3.1 (10Gbps) interface. The extra bandwidth made no difference in performance, and the T3 is still a little faster. More on the why of that later.
Price and DesignThe My Passport SSD is roughly 3.5 inches long, 1.75 inches wide, and a mere 0.4 inch thin. We can’t think of anything offhand that’s of a similar size, though an oversized lighter comes to mind. The important bit is that it fits handily in the palm of your hand, and readily into all but the smallest of pockets.
The drive weighs only a few ounces, and the two-tone, half-beveled design looks quite nice. A bit gaudier than the Samsung T3, but perhaps more interesting. The drive uses a USB Type C port, but comes with a C-to-A adapter for use with older systems.
WD
The beveled top gives the WD My Passport a nice look, and better grip.
Note that while WD, unlike Samsung, bundles some pretty fair backup software, we don’t recommend external SSDs for backup. That’s because all of the high-capacity USB SSDs we’ve used will occasionally, and seemingly arbitrarily, decide they no longer contain data. Recreate the partition and re-format, and they’re good to go, but the data is gone. We’ve experienced this type of failure with both the Samsung T1 and T3, as well as the Sandisk Extreme 900, with no discernible reason as to why.
PerformanceThe 1TB My Passport SSD is a bit faster than the Samsung T3 according to CrystalDiskMark, as shown below. However, both our 20GB copy tests and the AS SSD benchmark mildly disagree.
IDG
According to CrystalDiskMark, the My Passport SSD is faster than the Samsung T3, our other tests, including the hands-on, disagree.
In our 20GB files and folder tests (see the chart below), the WD My Passport SSD lags significantly behind the Samsung T3, especially when reading. The Sandisk Extreme 900 included in the comparison uses two M.2 SATA SSDs in RAID 0 to boost performance.
IDG
The Samsung T3 is still our fastest performer overall in the single-drive USB SSD category, but with large files you’ll never notice the difference with the WD My Passport SSD.
WD
AS SSD showed the WD My Passport SSD as faster reading, but considerably slower writing than the Samsung T3
If you’re wondering how a USB 3.1 Gen 1 drive (the Samsung) can keep up with or surpass a Gen 2 drive, it’s not the bus—it’s the drive. No SATA drive, such as those we believe to be inside the WD My Passport SSD (WD wouldn’t say what was in the drive—this is supposition based on performance) and Samsung T3, is going to transfer data at much over 500MBps, even attached directly to the SATA bus. Add a bridge chip and USB’s overhead, and 450MBps is pretty much the sustained limit.
Gordon Mah Ung/IDG
Western Digital’s My Passport SSD next to Samsung’s T3. Under both is a standard hard drive-based portable drive.
Nice jobWD has done a very nice job with the My Passport SSD. It’s slightly faster than the T3 reading, highly portable, and handsome. But it’s slower than the T3 with small files, so all things being equal—and yes, we’re talking price—the T3 is the better buy. Not that you’ll be disappointed with either. Both are so much faster than a hard drive, you’ll swear off spinning platters forever. Oh, wait…except for backup. And capacity. And price per GB.

Well, that didn’t take long. A few short weeks after reviewing the Samsung T7, SanDisk’s Extreme Portable Pro SSD (1TB) showed up at our door and easily surpassed its rival for the top-performing USB 3.1 Gen 2 drive. SanDisk’s drive doesn’t offer the T7’s handy and fun fingerprint security, but it’s about the same price and offers software-based password protection if security is a concern.
This review is part of our ongoing roundup of the best external drives. Go there for information on competing products and how we tested them.
Design and featuresClose rival, not quite as fast

Best Prices Today:
The Extreme Pro Portable is designed with an aluminum chassis and ABS top, and is IP55-rated (Ingress Protection), meaning it will fend off dust and low-pressure water. The ingress weak spot with storage devices has historically been the connection port, but Type-C ports, such as the one on the Extreme Pro, are far better sealed than previous types.
Note that the IP rating indicates survivability when disconnected. With electricity flowing through a cable connection, fluid can short cable pins, causing electronic damage.
Sandisk
SanDisk’s Extreme Pro Portable SSD has an aluminum (the orange parts) chassis with a dimpled ABS cover.
The Extreme Pro Portable SSD lacks the fingerprint reader that graces the Samsung T7; however, it does come with SanDisk’s own SecureAccess software security solution. It provides password protection for the drive’s 256-bit AES encryption (when enabled), though it must, of course, be installed on any device or PC from which you wish to access your data—not as convenient. Neither drive is FIPS 140-2 certified (Federal Information Processing Standards security), which will limit enterprise interest and rule it out for conforming government agencies.

Why is the Extreme Pro Portable so fast? While it does transfer data via speedy USB 3.1 Gen 2 (10 gigabits per second), it’s likely far more important that the internal storage uses the NVMe communications standard, instead of the slower SATA standard used by its Extreme Portable SSD predecessor. Beyond that, SanDisk offered no details, and I didn’t want to destroy the drive to find out what’s inside.
The WD store (SanDisk’s parent company) sells the Extreme Pro Portable in three sizes: 500GB for $120Remove non-product link currently, 1TB for $230Remove non-product link currently (the size we tested), and 2TB for $430Remove non-product link currently. We found the same prices on major online sites: 500GB for $120 on AmazonRemove non-product link and 1TB for $230 on Amazon. The five-year warranty is in effect no matter where you buy.
PerformanceIDG
In CrystalDiskMark, the Extreme Pro was rated as far faster than its predecessor and Samsung’s T5, but only marginaly faster than Samsung’s newer T7. Longer bars are better. Note that this chart was corrected after initial publishing to show the T5’s true, and lesser performance.
IDG
Though it was slightly slower than Samsung T7’s reading, the Extreme Pro Portable blasted its rival when it came to writing. Shorter bars are better.
IDG
The Pro version of the Extreme Portable rules when it comes to long sustained writes. No other USB SSD we’ve tested even comes close. Shorter bars are better.
The primary reason for the landslide victory was that the Extreme Pro Portable wrote at a relatively steady 600MBps or so, while the T7 started at over 500MBps and dropped to around 300MBps when it ran out of cache. That occurred at around 4 percent of total capacity, or the 20GB mark with the 500GB T7 we tested. More capacious models of the T7 will run out of cache later in the process, narrowing but not eliminating the margin of defeat.
Testing is performed on Windows 10, 64-bit running on a Core i7-5820K/Asus X99 Deluxe system with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (NVidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM2142 USB 3.1 Gen 2 (10Gbps) card. Also on board are a Gigabyte GC-Alpine Thunderbolt 3 card and Softperfect’s Ramdisk 3.4.6, which is used for the 48GB read and write tests.
It’s the winnerThe Sandisk Extreme Pro Portable SSD is faster and only a bit larger that the Samsung T7. I admit that I enjoy the Samsung T7’s fingerprint swiper, but otherwise, the Sandisk Extreme Portable Pro is the portable USB SSD you want when you’re dealing with large amounts of data.
This article was edited on 2/27/2023 to correct the discussion and chart for CrystalDiskMark which showed the Samsung T5 as being much faster than it actually is.
Ocz Octane Ssd Reviews Round
OCZ Octane SSD reviews round-up
This week we’re seeing the fabulously powerful and relatively inexpensive OCZ Octane 1TB 2.5-inch SSD hit the review block, and what we’re seeing here is that the manufacturers have backed up their claims in more ways than one. Price per gigabyte on this device is lower than the competition while the strength its displaying in this first round of hands-on looks is showing it to be more than a contender in the benchmark department. Could this be your next solid state drive, dare we ask?
While the OSZ Octane has been promised to achieve read / write speeds of 560MB/s for reading and 400MB/s for writing, it appears that reviewers have found this to be not all that far off from the truth. Have a peek at the specifications in this new OCZ offering first, then see what the real deal is.
OCZ Octane Specs
128GB (OCT1-25SAT3-128G) $199.99 ($1.56/GB)
256GB (OCT1-25SAT3-256G) $369.99 ($1.45/GB)
512GB (OCT1-25SAT3-512G) $879.99 ($1.72/GB)
1TB (OCT1-25SAT3-1TG)
• 512GB Formatted Capacity: 476.94GB
• Indilinx Everest platform
• Up to 560MB/s Read (1TB Capacity)
• Up to 400MB/s Write (512GB and 1TB Capacity)
• 512MB Onboard Cache
• 25nm Intel Synchronous NAND
• TRIM Support
• SATA 6Gb/s interface
• NCQ Support up to 32 Queue Depth
• 9.5mm, 2.5″ form factor
• Dynamic & Static Wear-Leveling, and Background Garbage Collection
• 8 channels with up to 16-way Interleaving
• Power Consumption: 1.98W active, 1.15W standby
“The Octane comes packaged like many other SSD’s out there, with a few extra presents like the “My SSD is faster than your HDD” sticker seen with Vertex units. … 1TB – in a 2.5″ form factor SSD! HDD’s hit this mark not too long ago, and while a 1TB Octane will most certainly cost a pretty penny, there’s something to be said for SSD’s so rapidly catching up to HDD’s for a given form factor. … Octane did well in sequential transfers with HDTach, but remember this particular test hits drives with a string of sequential (QD=1) IO, a notorious weakness of SandForce controllers.” – Malventano
Next see what Kevin OBrien of Storage Review had to say on another synthetic benchmark test by the name of Iometer, with the single chart showing off a Workstation 4K model profile, with results below:
“Our last section of synthetic benchmarks looks at the performance of each drive in enterprise profiles, including database, webserver, file server, and workstation. One of the main benefits of this test over other synthetic benchmarks is the mixed workload with both read and write transfers as well as varied transfer sizes at the same time. These are also scaled from a queue depth of 1 to 128 to fully stress the drive in a demanding environment. As you can see below the OCZ Octane stayed close to the group in the lower queue depths, but couldn’t scale up as high under a multi-threaded workload; although it did manage to stay above the Crucial m4 in all but the webserver test.” – OBrien
Then of course no review series based mainly in benchmarks would be complete without a visit by Anandtech’s Anand Lal Shimpi himself. Check out Anand’s review for a rather in-depth and interesting story on the history of OCZ if you like, otherwise just read this snippet on how well the drive works with their heavy workload test:
“When put to the test the Octane does not disappoint. It’s within a couple MB/s of the SF-2281 based Vertex 3, and effectively one of the fastest 6Gbps drives on the market today. I included the old Indilinx Barefoot based Corsair Nova V128 to show just how far Indilinx has come here.” – Anand
Look like a winner to you?
Video: Spacex’s Falcon 9 Rocket Lands On Drone Ship, Leans, Tips Over
SpaceX attempted to make history on Sunday by landing a rocket on an autonomous barge in the ocean. It didn’t quite go as planned, though.
After a successful launch of the Jason-3 ocean-monitoring satellite, the rocket’s first stage turned around and came plummeting back to Earth. Despite 12- to 15-foot ocean waves and foggy weather, the rocket booster managed to land very close to the center of the drone ship. It touched down gently… and then tipped over as a landing leg gave out. So close!
Here’s the video of the landing attempt, from SpaceX CEO Elon Musk’s Instagram:
One of the landing legs didn’t fully lock out to support the tall booster.
This is SpaceX’s third attempt to land on an ocean platform, but Musk is optimistic about the next one.
By his estimate, the company will face a few more of these “rapid unscheduled disassemblies” in 2023, with their success rate improving in 2023.
My best guess for 2023: ~70% landing success rate (so still a few more RUDs to go), then hopefully improving to ~90% in 2023
— Elon Musk (@elonmusk) January 19, 2023
X marks the spot
After a January 17 launch, the Falcon 9 closes in its landing target.
Getting closer…
Closer…
Nailed it! Oh wait…
After a landing leg fails to lock, the 135-foot tall rocket stage begins to tip…
…Resulting in this “rapid unscheduled disassembly”
“Well, at least the pieces were bigger this time!” tweets SpaceX CEO Elon Musk
