What hard drive comes with the Dell 15-3521 laptop
What hard drive comes factory with a Dell 15 - 3521 laptop computer
Hi @jpicking85 ,
According to the specifications it is capable of taking a sata 3 HDD or SSD. sata 1 and sata 2 drives will work because sata 3 is backward compatible but they will work at the slower speed
The capacity is not specified.
Here’s a link that shows what SSD are compatible with the laptop
From the factory, a 500GB SATA III drive if what I’m finding is correct based on Amazon. Most likely a Seagate hard drive since Dell loves them for the lower capacity drives like the one yours came with.
The problem with these factory Seagate drives Dell uses is long term reliability. After the 7.01/7200.11 disasters (7.01 eats your data alive by scraping the platters/7200.11 BSY FW error requiring BSY reset)
NOTE: The modern 2.5” Seagates aren’t any better, ESPECIALLY modern made in China Seagates although they have different issues or repeats of old issues like Rosewood platter grinding and the end result being unrecoverable). It’s quite common to find dead Seagate drives that are relatively new (1-4 years).
Due to their tendency to fail, I would recommend replacing it when you can afford to do so because 5 years is when they really begin to act up in my experience and yours is about that old. In many cases, they tend to show problems around the 10k+ POH range, give or take. Not all of these drives do fail, but they have enough have issues it’s usually better to do as preventive maintenance on a machine with one of them installed.
