The Addlink A93/S93 is a solid-performing PCIe 4.0, DRAM-less NVMe SSD that may prevent a couple of dollars. But the A93 with its heatsink faces heavy competitors from many equally priced and infrequently quicker SSDs.

PCIe 4.0 host reminiscence buffer (HMB) SSDs just like the Addlink S93 / A93 (heatsink) are all the fashion lately. Without the price of DRAM main cache added to the combo, the modules are cheaper to supply and might nonetheless match DRAM-designs in most efficiency areas.
That stated, the 1TB model of the S93/A93 I examined ranks low amongst a listing of very quick SSDs — primarily as a consequence of a really sluggish time in our 450GB write in comparison with the 2TB competitors.
Read on to be taught extra, then see our roundup of the best PCIe 4.0 SSDs to for comparability.
What are the Addlink S93’s options?
The S93 is a 2280, PCIe 4.0 x4 (4 lane) NVMe 2.0 SSD sporting a Phison P27T controller and 162-layer TLC NAND. It’s a number reminiscence buffer design, which implies in lieu of DRAM, your gadget’s reminiscence is used for main caching duties.
When it first confirmed up, HMB designs have been slower than DRAM in most areas. Now they commonly compete nicely by way of sequential throughput, although DRAM nonetheless guidelines in relation to random 4K operations. The hole appears to be slowly closing although.
Addlink warranties the S93/A93 for 5 years and the drives characteristic a 300TBW per each 1GB of capability score. That’s a bit on the parsimonious facet — truly, half of what we usually see from TLC drives.
The S93 is discount, the A93, not fairly a lot.
The again of the S93 NVMe SSD.
TBW signifies the quantity of knowledge that could be written beneath guarantee. Note, that you simply might be able to write much more than that earlier than the drive turns read-only. This is principally a vendor threat calculation.
How a lot is the S93/A93?
The S93 we examined may be very inexpensive at $68.44 for the 1TB, $133.44 for the 2TB, and $268.44 for the 4TB. The heatsink on the A93 provides extra bucks than I used to be anticipating, making the 1TB model $84.44, the 2TB $149.44, and the 4TB capability $312.44.
The S93 is discount, the A93, not fairly a lot. It’s a pleasant heatsink, however few customers want one and the graphene warmth spreader/label on the S93 dissipates a good quantity of warmth.
How quick is the Addlink S93?
The 1TB S93 Addlink proved largely aggressive performance-wise, if not up there with one of the best we’ve seen. What dragged down its total efficiency to 24th out of 29 PCIe 4.0/HMB/TLC SSDs that I’ve examined was its depressing 450GB write time. That’s primarily due to having solely half the NAND of its opponents obtainable for secondary caching.
As you may see, CrystalDiskMark 8 rated the S93’s sequential switch talents extremely when queues have been in play. But the single-queue efficiency was greater than a bit off the extremely ranked WD Black SN7100’s.
As you may see, CrystalDiskMark 8 rated the S93’s sequential switch talents extremely when queues have been in play. But the single-queue efficiency was a bit off the competitors. Longer bars are higher.
Random efficiency in CrystalDiskMark 8 was higher, and really comparable with a single queue in play. The Lexar’s tragic numbers in these assessments have been largely a matter of subpar caching, as they turned aggressive after we diminished the CrystalDiskMark 8 knowledge set to 16GB.

I’ve nothing to complain about with the A93/S93’s 48GB switch occasions. It’s good in widespread real-world eventualities.
I’ve nothing to complain about with the S93’s 48GB switch occasions. Shorter bars are higher.
The 450GB is the place being solely 1TB in capability damage the S93/A93 — there’s merely much less NAND to deal with as SLC secondary cache. However, the slowest write pace was nonetheless a SATA-like 600MBps, so this isn’t fairly as tragic as you may suppose within the grand storage scheme.

Again, in its 2TB taste, the S93/A93 would seemingly have ranked a very good deal larger.
Note that initially I used to be set to check the heatsink-clad A93 that Addlink additionally supplied. Alas, to make use of the SSD in my upside-down secondary PCIe 5.0 M.2 slot, the heatsink needed to go.
Rather startlingly, the 2 NAND chips got here off the PC board together with the heatsink and its thermal coupling materials. This mustn’t occur, and was a primary for me after performing quite a few different comparable operations. Make positive you go for the naked S93 in the event you don’t want or can’t use a heatsink.
Should you purchase the Addlink S93/A93?
The S93/A93 is hardly a barn burner within the class, however it is going to do the job, and in its S93 incarnation it’s outstandingly inexpensive. That stated, I like to recommend the 2TB model and on the lookout for it on sale.
How we take a look at
Drive assessments presently make the most of Windows 11, 64-bit working on an X790 (PCIe 4.0/5.0) motherboard/i5-12400 CPU combo with two Kingston Fury 32GB DDR5 4800MHz modules (64GB of reminiscence whole). Both 20Gbps USB and Thunderbolt 4 are built-in to the again panel and Intel CPU/GPU graphics are used. The 48GB switch assessments make the most of an ImDisk RAM disk taking over 58GB of the 64GB of whole reminiscence. The 450GB file is transferred from a 2TB Samsung 990 Pro which additionally runs the OS.
Each take a look at is carried out on a newly NTFS-formatted and TRIM’d drive so the outcomes are optimum. Note that in regular use, as a drive fills up, efficiency might lower as a consequence of much less NAND for secondary caching, in addition to different components. This could be much less of an element with the present crop of SSDs with far quicker late-generation NAND.
Caveat: The efficiency numbers proven apply solely to the drive we have been shipped and to the capability examined. SSD efficiency can and can range by capability as a consequence of extra or fewer chips to shotgun reads/writes throughout and the quantity of NAND obtainable for secondary caching.Vendors additionally often swap parts. If you ever discover a big discrepancy between the efficiency you expertise and that which we report, by all means, tell us.
