It depends on what kind of performance you're looking for and how you value that performance.
Under sustained long duration (ie: hours to days) of continuous full load performing small block writes, even the highest rated consumer SSD drives will begin to show significantly reduced throughput in comparison to pretty much any enterprise SSD drives.
Additionally, it's totally normal to see >=5 drive writes per day and 5 year warranties on enterprise drives. Consumer drives usually are rated significantly below 1 drive write per day and rarely for more than 3 years of warranty. If you're performing a lot of writes, you're going to need to replace worn out SSDs and that's not free in a business (remote hands, downtime, etc). So buying less durable storage has costs which don't show up on the original purchase invoice but do need to be factored in within a business setting. The warranty period is the best indication of how confident the drive vendor is about drive durability.
- Retric 3y agoMore total space for the same price changes that equation. Spending 2+X per GB means rather than 5x the same X it’s 5 times 1/2 or less total space. And that’s before you consider write amplification issues with having dramatically less total SSD space. Enterprise SSD’s have a few benefits, but they shouldn’t be your default choice for all servers.
- vetinari 3y ago> Consumer drives ... and rarely for more than 3 years of warranty. Looking at my list of consumer SSDs and their warranties: Samsung EVO 850: 2y Samsung EVO 960: 3y Samsung EVO 860: 5y Samsung EVO 970: 5y Samsung PRO 970: 5y For comparison with spinning rust HDDs: Seagate Ironwolf: 3y WD Red (both EFAX & EFRX): 3y
- bradfa 3y agoBut take a wider sample of consumer SSDs, a large majority are <=3 years. And look at enterprise SSDs. Seagate Ironwolf and WD Red are not enterprise spinny hard disk drives, instead look at Seagate X18 or WD HC560.
- vetinari 3y agoYes, I know, I was comparing warranty on consumer SSDs and consumer HDDs.
- bcrl 3y agoConsumer drives usually exclude wear out in their warranties making the number of years pretty much irrelevant. What is does show is that vendors are more confidence in their FTLs and hardware nowadays compared to the first high volume SSDs on the market more than a decade ago.
- osigurdson 3y agoI always complained to our IT group about storage - until they showed me an invoice for the drives they are buying.
