YiwerDer 50Pcs Antistatic Resealable Bag 15X20cm/5.9X7.9inch, Premium Anti Static Bag for SSD HDD and Other Electronic Devices

Great bags. Love how they are resealable. Works well for all sizes of hard drives as well as small pci cards.

I have hot swap bays in my PC's and I keep hard drives to swap in and out depending on what files I need. I needed some zippered antistatic bags to keep them in and these work very nicely. Losing one drive can be a big deal if you don't have backups so definitely keeping them in antistatic bags is a good idea. Use these and protect your data if you keep spare 3.5 drives around. Even if it is an old drive you just keep handy for a spare. These will protect it nicely. And best of all they are not open ended like the bags that most drives come in. Making them more convenient as the drive won't fall out when stored.

I use these to organize cables and also for packing miscellaneous items. Good size for most tech cables, even up to 10 ft.

This product is very straight-forward and it's hard to knock it on any particular point. The YiwerDer bags feel substantial and seem durable. They also seem to provide protection against static thus far (though it's fairly hard to thoroughly test this aspect without some sort of testing apparatus). If you're looking to store the standard 3.5-inch hard disk drives, then the 15 cm x 20 cm / 5.9-in. x 7.9-in. bags are the ones you're looking for. The 3.5-inch HDDs fit quite snug inside vertically and the ziplock seals right above the end of the drive (so no space for any extras like accompanying SATA cables or whatever, if you wanted to put those in there, too), and it may be slightly difficult pulling the drives back out (best to unseal the bag, then gently slide the hard drive back out past the ziplock tracks that keep the HDD stuck inside the bag). For storage and/or travel, it does what it needs to do. Would recommend a buy.

Great size, have more than I need worth it so far
