Recommendation for small/cheap SSD

[Afasoas]

I'm looking for either a 16/32GB SSD for a home-brew web/mail server project.
SATA II/III - speed isn't important.

SSD preferred over anything mechanical on grounds of low power consumption.

Thanks

I'd employ any second-hand OCZ for that job - wouldn't matter if 60 rather than 32 GB, and being well used wouldn't matter, because they don't suddenly wear out and die, they just gradually get slower or reduced in capacity.

Maybe cheaper to use a compact flash card or SD card in an adapter.

Just bought a 32GB one from fleaBay for £17, posted. T'is only SATAII with fairly lowly (for an SSD) performance but that should still be much more than adequate.

By comparison:

16 GB CF card + Adapter via eBay = £20ish
64 GB SSD from Newegg = £25

Or a USB memory stick.

I've been looking at some more specs recently and it's interesting that SSD power consumption isn't always lower than 2.5" HDD, even when idle, and most SSDs don't have a standby mode, unlike HDDs.  It doesn't necessarily equate to SSD speed.

For example, OCZ Agility 3 SSD (an older "budget" model that you might get second-hand): 1.5 W idle, 2.7 W active.
OCZ Vertex 3 SSD: 1.65 idle, 3 W active.
Seagate 2.5" HDD: 1.2 - 1.5 W "average operating power".
WD Green 2.5" HDD: 0.2 W standby, 0.8 W idle, 1.7 W active.

But some SSDs are very good on this score, eg. www.Sandisk.co.uk/products/ssd/sata/standard/?capacity=64GB - 50 mW active.  And the Samsung 850 Pro I just got has a 2 mW standby mode (and a 10 year warranty!).

I think the whole box is clocking in at around 0.005-6 kWh so the disk in it can't be too bad.
The trouble with a mechanical HDD is the spin-up time once it has gone to sleep. Not ideal in a web server. S'pose the answer is not to let it sleep


On edit: I've added some decimal spaces. 5-6 whole KWh sounds a bit silly.

A WD Green 2.5" HDD could use less power than many SDDs even if spinning all the time.  That is if their term "idle" means spinning.

I'm only nit picking as it's a tiny amount of power in either case, and I'd have an SSD for other reasons anyway.
