Odd Hdd Enclosure
Overview
Product sourcing insights & recommendations
I have completed a detailed analysis of the 'odd hdd enclosure' (ODD bay caddy) market and product trends for 2026.
The analysis confirms that while built-in SSDs are standard for new hardware, a significant market remains for ODD caddies as secondary storage solutions, especially for high-capacity media and "cold storage" backups. Key findings include a projected 6.12% CAGR for the HDD market through 2031 and a surge in consumer interest in DIY hardware maintenance as evidenced by recent search trends. The report also highlights critical technical considerations like 9.5mm vs. 12.7mm height compatibility and SATA interface bottlenecks.
The comprehensive report below includes market projections, technical comparisons, and sourcing recommendations based on current B2B data and consumer insights.
Based on this market analysis, here are your next steps:

Can you replace a 12mm drive with a 9.5mm? There might be a gap, but could you pad it somehow? I’m seeing more 9.5mm on sale now than 12mm and I need to place my dead 12mm. ... I just got a caddy and I tried with new SSD int optical bay, but it seems to jam a lot my laptop and it’s never visible, it’s like very slow or something… · Should I just switch HDD and SSD and never question why SSD is not working on the caddy? Generally speaking, it’s almost always better to put the SSD in the primary slot (where the HDD originally was). There are a variety of reasons why the caddies tend not to work quite as well with SSDs. ... @nhinkle: I’m planning to buy a laptop from xoticpc and one of the customization options is to replace the disk drive with a hard drive. Note: Part II, installing and configuring the optical bay caddy, is now posted! Have you ever wished you could put an SSD in your laptop, but realized that you have far too much data to fit on an affordable SSD? By putting a hard drive caddy in your optical bay, you can add a second hard drive to your computer, allowing you to install your operating system, applications, and other frequently accessed files on an SSD, while storing all of your large files on a regular hard drive. When in doubt, you can always remove the drive and measure it yourself with a ruler. Optical bay caddies will have a SATA connector on the hard drive end, so any modern hard drive or SSD will work in them (though SSDs have their own problems with caddies, so it’s often better to put them in the main hard drive slot – more on that later).

Maybe caddy was of poor quality and got hardware failure within first month of use or then it was the HDD that had defects. The HDD heating was one concern for me as the optical bay is not ventilated. Not surif it shortens the life of the HDD. Supposedly the HDD will operate cooler because work is split between SSD and HDD ... I just replaced my ODD with a SSD, clean installed Windows 10 and for some reason the boot of the system takes a stupidly long time. Pavol, Most notebook ODD connectors are only SATA not II or III this means using a solid state in its place wouldnt make much sense because the speeds will be bottleneck’d by the hardware. your best bet would be putting a SSD in the original drive spot and putting a HDD for access files that dont require fast speeds in your ODD spot.c ... This is a community blog for Super User. More community blogs are available at Blog Overflow. ISO files, optical drives and bootable flash drives It’s been a while since I wrote about my optical bay HDD caddy experiment, but the results are finally in. I’ve been running my laptop for over a month now with a Kingston V100 SSDnow in the primary storage bay and the original hard drive in a NewmodeUS optical bay caddy, and have been quite pleased with the results. The optical drive should just slide right out smoothly. Don’t force it too hard. Once it’s out, set it aside somewhere safe. Next, install your old hard drive into the optical bay HDD caddy. It should slide in easily, and then be secured with four screws on the bottom of the caddy.
r/buildapc on Reddit: Optical bays?

FRACTAL Pop case is always a choice. This case support optical drive bays. I think two. https://www.fractal-design.com/products/cases/pop/ ... Personally I'd go for an external caddy. Fractal Design Define r5 supports your stupid optical drive mount. ... Haha! I just want to be able to use old media sometimes. ... I bet you could find an external enclosure for an internal drive to avoid buying an entirely new drive. Optical drives are far less important than they used to be for most users, and the extra bits to mount one can impede airflow so for most people, it's best to just not have it. There are a handful that do but they aren't common. There are USB enclosures for SATA and PATA optical drives if you need to keep an old drive in service. GPUs have gotten so large that with the typical place meant of the drive bay on cases supporting optical drives, you will not be able to fit your GPU in. I ruined a 4 TB HDD trying to put a little RX580 into an old case. The GPU pressed against wires for the HDD and I guess there is a hairline crack there.
