## Questions & Answers

**Q: What is tbw for s55 ?? hopefully i can get the answer from the manufacturer**
A: @Carson - to answer your question, the OP was asking what the TBW for the S55 series of drives from Silicon Power is.

First some preliminary info:
Unfortunately, the question was probably asked incorrectly, at least the vendor appears to believe so as the vendor provided the info for the A55 series. The S55 series is in sizes 120GB, 240GB, 480GB, and 960GB. The A55 series is in sizes (in GB) of 128, 256, 512 (and in TB) 1, 2, 4, 8, 16TB.

All things being equal, they are relatively the same in performance specifications (S55 and A55 of nearly same sizes). However, the S55 series is pretty much defunct by now, though you can still find them available.

Now, on to answer your question:

TBW stands for Total Bytes Written. It is the standard of measure for how long the SSD drive will last, or more correctly, how long you can still write to it. In layman's terms, SSD drives can only have data written to them so many times (in actuality it is the "erase" function which clears a block of space on the drive that this really relates to) and so they in a sense "get used up" after a period of time. All in all it boils down to the old MTBF (Mean Time Before Failure) that regular magnetic hard drives (HDDs) are measured against.

TBW is generally measured in Terabytes (unless otherwise stated) so as an example, if you have a 512GB (Gigabyte) SSD drive that has a TBW of 250 it means that you can write up to 250 Terabytes of data on the drive before you can no longer write to it. In this example, that means you could completely write to the entire drive (and erase/overwrite it) 500 times (512GB being half a Terabyte relatively).

Once you have reached the TBW of the drive, you could no longer write to it, though you can continue to read the existing data on it for as long as the drive works "electronically".

Hope that answers your question as well as possible.

**Q: Does it have power failure protection?**
A: does it matter?  the purpose of power loss protection is to write data from the dram cache to nand (flash) in the event of power loss. If an SSD does not have dram cache (such as this), there are no writes to in dram to protect.  does that necessarily mean a drive is good or will survive a power loss?  depends on firmware-if done correctly, yes.  dram is much faster, so for high end drives, dram is almost a necessity.  some of them with dram to hit high performance numbers do not have power loss capacitors...if you're looking for an application or use case that needs both the performance of dram caching and power loss protection of that dram cache, you likely already know enough to know the answer.  if you don't have one of those use cases, power loss protection is really a moot point.  This is not a drive someone would use for a ZFS ZIL, or a virtual machine swap file datastore, or big SQL server temp db..

**Q: Is this a good boot drive?**
A: I used to own a comp company..still build several high end rigs a year and enequivacly can say these are excellent "not " drives.

Very stable through all functions esp here in Hawaii with sometime spotty power supply.

Rgds and aloha

**Q: Anyone else have problems with this drive not registering on userbenchmark?**
A: I have not had any issues at all with this drive. I just recently installed it on my pc and it works perfectly
