Transcend is probably a name you’re familiar with, and for good reason. The multi-faceted company is best known for its memory with a long history of reliable, if unassuming, products. The MTE260S, or 260S, SSD is no different, adorned with a simple graphene heatspreading label that hides a drive with a lot of potential. It’s not one you should overlook if you’re searching for power and consistency from a brand you’ve actually heard about.
In that respect, the 260S has a lot in common with Kioxia drives like the Exceria Plus G4. While such drives are using licensed controllers like most other brands, you will usually have custom firmware and potentially hand-picked flash. The hardware also tends to be more consistent. As these drives are made for environments where reliability is important – in pre-builts, for small businesses, etc, this usually means they have a better track record. Performance may not be as good, but that’s often a worthwhile compromise. The 260S uses mature flash and has a simple but effective design that, while winning it no prizes, makes it a good alternative in this challenging market.
The Transcend MTE260S, or 260S, is available at 1TB, 2TB, and 4TB. Currently, the drive is out of stock, but this is one of those models you might be able to catch randomly at a good deal. Transcend drives are often available for good prices. They also tend to be more reliable than drives from generic brands.
This is a very fast drive with maximum performance around 14,500 / 13,500 MB/s for sequential reads and write workloads and up to 2,000K / 1,400K read and write IOPS in random workloads. The IOPS count might be lower than you’d expect from a drive in this class, but this needs to be taken within the proper context. Transcend makes OEM or client drives – drives used for prebuilts, businesses, etc – which usually have stricter operating requirements. The drives will often be more robust and consistent, and this could mean custom firmware that is, as a side effect, more restrictive of peak performance. This actually isn’t a bad thing, as you’re generally not reaching anywhere near two million IOPS. The given sequential numbers are also from ideal workloads with very high queue depths. So take that into consideration when comparing this model directly against the competition’s numbers.
Transcend doesn’t skimp on the warranty, covering the full five years with up to 750 of data writter per TB of capacity (750TBW). This is 25% above the normal 600TBW. Often, OEM drives, particularly low-end ones like the WD Green SN3000, will skimp on shorter warranties and lower TBW. Not so with the high-end 260S.
Transcend 260S Software and Accessories
Transcend offers a surprising number of downloads for its products. For the 260S we’re most interested in SSD Scope which is Transcend’s SSD toolbox. While not fancy, SSD Scope has all the features you need. You can monitor drive health and diagnose problems, run secure erase or TRIM, update the firmware, and backup/clone your data, all in a single app. These are essential tools for any storage device and make it easier to transition to a new drive. While by no means a requirement, it’s nice to have this standard functionality.
The Transcend 260S is a double-sided drive at all capacities and is rated for around 10W. This is perfectly in line with expectations for a high-end PCIe 5.0 SSD. Transcend also has a graphene label and heatspreader on the drive, which is a nice bonus. This material can be effective even with high-end drives because, for one, newer controllers are more efficient to begin with, and two, full-length M.2 2280 drives have enough distance between components to make heatspreading more effective. There are two NAND flash packages on the rear that do not benefit directly from this, though.

If we uncover the drive top drive components, we see the SSD controller, a single DRAM package, and two more NAND flash packages. The controller is the Silicon Motion SM2508, which is one of our favorites. For the non-volatile DRAM cache, Transcend uses Samsung DDR4. If we look at the coding we see “8G16” on the module which means 8Gbit, or 1GB, in a 16-bit configuration. This gives a total of 2GB of DRAM with the usual DRAM:NAND memory ratio of 1GB:1TB for optimal operation even under heavy workloads.
Deciphering the flash is more challenging, but we know these are 4Tb packages – 512GB each, for a total of 2TB – and were manufactured in week 17 of 2025. Underneath, we know these are using Micron 232-Layer TLC flash, which, although not the newest, is relatively good flash. Transcend uses smaller BGA packages for this, which is not unusual, but some users might be expecting larger ones.
Smaller packages have advantages with tight PCBs, and it can be better for I/O sensitive flash, which is definitely the case with Micron’s – consider the multiplexors we’ve seen on the 4TB Crucial T500 and other drives with this same flash. Theoretically, smaller packagers can also limit how much you can stack flash and can reduce the surface area for cooling. The 260S caps out at 4TB, and the graphene label on the controller and DRAM side is more than adequate. Further, as we mentioned under the specifications section, this drive is designed to operate more consistently as it’s a client drive – that is, made for consumer use but specifically for pre-installation with stricter operating standards – so any concessions made with component selection are not an issue within the intended thermal and performance envelopes.
