FAQ
TL;DR: For 2TB in 2.5-inch, 1 vendor dominates; “SSHD for storage is not needed, regular HDD is enough.” Choose on warranty, not cache. [Elektroda, dt1, post #16953738]
Why it matters: This FAQ helps laptop users pick a durable 2.5-inch 2TB data drive without overspending or risking avoidable failures.
Quick Facts
- 2.5-inch 2TB choices are effectively Seagate models in this thread. [Elektroda, dt1, post #16953792]
- FireCuda SSHD adds 8 GB NAND cache; Barracuda is pure HDD. [Elektroda, majster-klepka07, post #16953108]
- Typical warranties noted: Barracuda 2 years; FireCuda 5 years. [Elektroda, majster-klepka07, post #16953108]
- Using a bare 3.5-inch drive via simple USB–SATA cable from a laptop won’t power it. [Elektroda, dt1, post #16955679]
- HDD longevity is a “lottery”: a new unit can fail early or run for years. [Elektroda, sylweksylwina, post #16953828]
Which is better for pure data storage: Barracuda HDD or FireCuda SSHD?
For storing files, SSHD speed doesn’t add value. Pick based on warranty and price. “SSHD for storage is not needed, regular HDD is enough.” [Elektroda, dt1, post #16953738]
Will the FireCuda’s 8 GB NAND wear out faster than an HDD?
Semiconductor memory does wear with writes, but the small cache and controller policies limit impact. A forum expert wouldn’t worry about its lifetime in this use. [Elektroda, sylweksylwina, post #16953197]
Are there many 2TB 2.5-inch options?
In this size, the thread identifies only Seagate 2TB 2.5-inch models. That narrows your choice to Barracuda or FireCuda. [Elektroda, dt1, post #16953792]
Does the FireCuda’s longer warranty make it a safer buy?
If warranty peace of mind matters, the longer SSHD warranty can be worth the premium. It may prove useful within five years. [Elektroda, dt1, post #16953792]
Is WD Black a good alternative at 2TB in 2.5-inch?
WD Black carries a 5‑year warranty, but 2TB 2.5-inch availability is limited per the discussion. Confirm stock before planning around it. [Elektroda, dt1, post #16953792]
Can I power a 3.5-inch HDD from my laptop with a USB–SATA cable?
No. A simple USB–SATA cable won’t power a 3.5-inch drive from a laptop. Use an external enclosure with its own power. [Elektroda, dt1, post #16955679]
Is it safe to run a bare drive over USB without an enclosure?
Avoid it. Running a naked drive over USB increases damage risk. Use a proper external enclosure instead. [Elektroda, sylweksylwina, post #16958704]
Should I buy one 2TB drive or two 1TB drives?
Two drives use more power and are less portable. With two, a single failure loses part of data; with one, you lose all. Consider RAID 1 if redundancy matters. [Elektroda, sylweksylwina, post #16958832]
Do two disks in a laptop draw noticeably more power?
Yes, two disks mean higher energy consumption. Check your bay space and power budget before adding a second drive. [Elektroda, sylweksylwina, post #16958449]
Is HDD reliability getting worse, or is failure random?
Expect variance. One drive can fail early while another runs for years. Treat HDDs as a reliability lottery and keep backups. [Elektroda, sylweksylwina, post #16953828]
Does 8 GB of SSHD cache help with storing large media files?
Not much. The small cache favors repeated reads of hot files, not bulk cold storage. Prioritize warranty over cache size here. [Elektroda, dt1, post #16953738]
What’s the practical difference between 5400 rpm and 7200 rpm here?
The thread notes WD Black models at 7200 rpm, but availability at 2TB 2.5-inch is unclear. Choose based on what you can source reliably. [Elektroda, majster-klepka07, post #16953788]
How do I add a second 2.5-inch drive using the optical-bay caddy?
- Install a compatible HDD/SSHD into a laptop optical-bay caddy.
- Secure it and insert into the DVD bay slot.
- Initialize and format the drive in the OS before use.
[Elektroda, majster-klepka07, post #16958460]
Should I pay extra for SSHD speed if my OS is already on SSD?
No. With the system on SSD, SSHD benefits shrink for data storage. Choose a regular HDD unless the longer SSHD warranty sways you. [Elektroda, dt1, post #16953738]
Any edge cases I should plan for?
Yes. A brand-new laptop drive can still fail under warranty, while an older desktop drive may run flawlessly for years. Backups are non-negotiable. [Elektroda, sylweksylwina, post #16953828]
If I must go external, what’s the safer approach?
Use a ready-made USB 3.0 enclosure for 2.5-inch drives. It protects the disk and provides proper power and connectors. [Elektroda, sylweksylwina, post #16958704]
